Great staff and top-of-the-line products, much better than my previous experience with the other Gravinas....

We paid over $200,000 to have Gravina's replace the windows and siding on our home in 2025. The project ended with a house fire. Fire investigators concluded that a gas fireplace vent was improperly installed during the siding work. When we used our fireplace that fall, the vent failed to exhaust correctly, causing heat to build up inside the wall cavity and igniting a fire. The photos attached show the vent missing during installation, added later, and the fire damage concentrated around that location. Our family has been displaced from our home since late 2025. We got sick from smoke and debris inhalation and are still dealing with the health effects. It is now June 2026 and we still don't know when we'll be able to safely return. No contractor should leave a family in this position. The project's permits were never finalized and the required final inspection was never completed before the work was closed out. Following the fire investigator's report, our insurance company is pursuing legal action against Gravina's. If you hire this company, verify every permit is finalized and every inspection is signed off, especially any work near gas lines or venting, before you make final payment. read more

I'm really disappointed with Gravina's. They did our siding a number of years ago and they were terrific then. We are now looking to replace some windows and doors, so I put them at the top of my list because of our past experience. Wow! Have they changed! We had an appointment for an estimate on a Saturday at 10 am. 10 o'clock comes and goes and nobody. Bear in mind the guy that was supposed to show up was the same guy I had talked to and set the appointment with. I called him and when I asked if he was going to show up his response was "What?". Told me he thought he had the day off and was just relaxing. I will never reach out to Gravina's again for anything. read more

We just had 12 windows replaced. We were pleased with the installation process and Jeremy (the guy who performed the work). The end result exceeds our expectations. read more

We couldn't be more pleased with the service and quality provided by Gravina's Windows Denver! The location we used was on Evans. Owner is Nick. Salesman was Michael. There's some negative reviews here and I'm not sure why. Perhaps they used a different location, which can be confusing. In our case, from start to finish, they exceeded all expectations. The team is top-notch, offering outstanding customer service and fantastic follow-through at every stage of the process. They replaced nearly all of our wood windows--around 27 in total--and the installation was flawless. The installation team, Sterling and Tyson, were especially considerate, trustworthy, and detail-oriented. They took great care in ensuring everything was done right, leaving our home looking beautiful and making the entire process smooth and worry-free. In today's world, it's so refreshing to find a company that not only delivers a fantastic product but also goes above and beyond with excellent follow-through. Gravina's Windows Denver truly stands out in this regard, and we would highly recommend them to anyone in need of window replacement. We will definitely use them again for any future window projects! read more

If you are thinking of replacing windows in your home, stay away from GRAVINA SIDING AND WINDOWS located in Denver. They make a good sales pitch, but the people they hire to do installation were extremely incompetent. When they arrived, I could tell they were in a hurry; and as a result, they did not clean up properly and left me with wood cuttings on the ground outside the window. The caulking was uneven and sloppy on the inside of the window as well as outdoors. In addition, there were gouges on the outside siding (See attached pictures). Initially, I gave the owner half of the entire amount. The other half was due after installation. I asked the incompetent installer if the owner would be there to inspect the work before payment. He said that the owner doesn't do that. Red flag for me!! The installer refused to leave until I gave him a check. However, upon inspection of the horrible job, I stopped payment on the check and told the owner, I would only release payment when all errors were corrected to my satisfaction. The owner, after seeing the pictures, said it was only "cosmetic", and he refused to compensate me for the paint I needed to buy to fix the poor craftsmanship. He said, in a threatening way, if he did not receive payment, he would put a lien on my house!!!! While I did end up paying him after he sent another employee to fix the bungled job, he reluctantly gave me a minor $100 discount for the hassle and stress and trauma that this has caused me. Choose another window company!!! read more

Just had replacement windows installed. Cost was in line, delivery was on time. Install crew was knowledgeable, professional. Thank you Gravina's. read more

I was so put off by the Renewal by Anderson and Pella sales people, that I thought going with a local business would be a good choice. Wow! Was I WRONG in a big way! We ordered our windows in Feb and the installation wasn't "done" until July. we bought the highest end Great Lakes windows. First, they sold us windows that didn't fit the width of our window wells - so they had to jury-rig a 1.5" spacer to make them fit. When I paid $40k for windows, I wasn't terribly happy about a ghetto fix to the job. I was shocked at how poor the windows looked in our house. My old windows had a nice aluminum frame that the windows fit into. The Great Lakes windows didn't have the frame, so the installers used massive amounts of caulk to fill in the surrounding area. I would typically expect at the end of having new windows put in, to have clean windows. I was wrong! We had to pay our window washers 700$ to get all the crap off of our windows from the installers (when it's usually 200$). The installers said they would split it with us, but never did. To add insult to injury, Gravina's accounting person hounded is to pay for the job before it was even complete. When we finally paid the last bit, but had the promise to get the last couple bits done, we didn't hear from them again. I've attached a couple pictures - one is my old windows, they are dirty but look nice, the other is the caulk-filled ghetto version from Gravina's. read more

Gravina's Windows & Siding - Old windows with a nice frame. - Windows Installation Near Me - Denver, Colorado

We replace 8 windows from hail damage. One window we upgrade to insulated and one more upgrade of the bathroom window to open. We never should have upgraded to insulated. We were never told that these window collect dew or moisture on the outside making it impossible to look out should there be a high moisture day. They never told us. Their screens are horribly cheap and floppy. They cut through our old screens and scrapped them so we could not reuse them. I would prefer my old screens, Gravina's are junk.....We will not use them again. Although we were not completely dissatisfied, we were not satisfied either. read more

like Mike D , I too am extremely disappointed at the lousy service going on two months since paying over three hundred to trouble shoot and the parts aren't here and more charges are coming $75 an hour for warranty worK?? Give me a break , Mr Gravina does NOT care the least bit. These windows are terrible and cant open or close,and they are brand new. Go buy some where else Make sure you read all the negative reviews there are many. Joe C said what I was thinking Nick Gravina got his fathers business and is ruining it whit terrible customer sevice , his attitude and rude demeanor is loud and clear. Talking to him is painful because he has excuses for everything . Worst customer service after 55 years of homeownership and I take pride , Gravina does not have any. go elsewhere.. read more

John came by and took window measurements and had a long discussion with us about the process. Said he would give the estimate the following week (4 days later) but nothing came through. I spoke to someone at the office and he said that John said we were supposed to go to their showroom to discuss the estimate. But John clearly said he would email it to us. I finally spoke to John and he apologized and said he would send it the next day. Nothing arrived. This was a waste of our time, and with both of us working, we don't have a lot of extra time to spare. Based on the multitude of other negative reviews here, this company apparently isn't listening and doesn't seem to care how they interact with their customers. read more

Every piece of the process with this company was not only painful, but full of lies. Ordered average amount of windows Nov 2020....informed they would arrive no later than Feb. (but with weather could be later for install...reasonable). Mid APRIL they send ONE installer (and his young son) to install 20+ windows, 2 story house with bay's etc). This 2 day job took 4 (mostly because they only showed up 11am- 3 pm). OH and 5 windows broke/were missing so this fiasco dragged on til Aug Gravinas NEVER contacted us when one arrived - the windows magically appeared after we called....slowly over time. Miserable team overall. Great windows ((hopefully) but not worth their BS. read more

Terrible company, garden window was never installed properly. I submitted pictures to the manufacturer, and they indicated that the company failed to use the supplied brackets. failed to support the window adequately or accurately, and as a result their manufacturer warranty will not be honored. Contacted the company in May 1st and they agreed to send have their service department contact me. Never heard back so two months later, I emailed them the response from the manufacturer. They finally called today, and said that lead warranty representative was unqualified to evaluate the problem. They only warranty their work for 2 years, and now claimed that I was told it would be $125 for them to come out. They never made that offer. Family members with the same name and similar business have indicated that they are obnoxious to deal with. The give the owner the nickname of Nick the Pr**k. Stay far, far away. Terrible company. read more

I used them to replace one window. Delivery was scheduled within 4-6 weeks. However it took them 3 months to deliver it!! At delivery it turned out to be wrong window. In the end I went to Home Depot and purchased the same window for half the price. Terrible service, bad coordination, ones the sale is done, the service is bad!! Be careful read more

We are having our kitchen remodeled and we added a large bow window to an outside wall. We also wanted to replace our patio door. The owner came out to our home to measure the custom order and had the order delivered to our garage. During the ordering process we received updates regularly. Great communication and knew exactly what product would work perfectly! AAA+ company to purchase from! read more

The upside is we saved $2,000 over another quote for the same 4 windows but we WAY overpaid for an install that was sloppy and actually cost us more work. The windows were the last phase of a total TV room remodel so we couldn't wait to see the finished product but the windows were so filthy when the installers left it took several hours to clean them using a razor knife and industrial cleaner to remove smeared caulk, dirt and fingerprints...and they damaged brand new drywall in two places and dinged up the wall everywhere so the freshly painted wall in that room has to be completely re-painted, which is frustrating because it wasn't necessary, just careless and inconsiderate. Technically, I'd say they get a C+ for the overall install as there were other small issues as well, but they get an F for showing absolutely no pride in the final product that we paid good money for. We had to show them twice (in the same place) where there was light and cold air coming through around the window and they finally caulked it but then we showed them how one of the windows was crooked (vertically) and could be clearly seen both inside and out, and then even gave him the measurements to prove it but the installer just blew it off and dismissed it. We decided it wasn't worth the re-install anyway and just gave up on it. When looking at the windows from outside you could see caulk all over the surrounding green trim (easily prevented by just simply taping it off) and instead of looking like brand new windows, they looked like they'd been there 30 years. When you pay $1,000's of dollars for something, and then pay an additional premium for installation, you expect it to be perfect and these were far from it. That, and the fact that we had to wait 3 months to get them with zero communication from the sales staff rendered the overall purchase a very disappointing experience. We have a whole house full of windows (and siding) to replace and these guys could've won our business but I don't think I'd feel confident purchasing from Gravina's again. read more

Gravina's came out and measured my patio door. It has some framing issues. Christy left never heard back!!

I read through all the reviews, and will say I completely disagree with the negative/1 star reviews. Sales was patient and knowledgeable in answering all my questions, helping me determine which type/style of window would be best for my home. 5 stars to Jason. Installers were great, courteous, knowledgeable and treated my home like their own. They cleaned up after themselves, cleaned all windows (inside and out), and educated me on all the features of the windows. 5 stars to Sterling and team. After installation, I noticed some manufacturer defects. I called Gravina's, and their customer support was stellar. Karl came out, listened to what my issues were, and committed to addressing the issues. He did everything perfectly, addressed my issues, and ensured my satisfaction. 5 stars to Karl and team. My windows exceed expectations from comfort, aesthetics and functionality. Due to the quality of service and product, I'll be ordering a front door, storm door and a slider to match. We've used Gravina's for whole home window replacements in two homes, and when the time comes, will use them a third time. Got burned by fly by night company (Reflection windows and doors), Gravina's earned my trust and business for all future upgrades. Well done Gravina's! read more

Worst most unethical company ever. Don't waste your time go to Home Depot and get a much better price and deal. Bad work that they won't warranty and try to charge you to fix! read more

Visited them 8 weeks ago and I am still waiting for a quote on windows and doors for a new build - probably a $25k job. Clearly it's not coming so I am moving on. Only one person there seemed to know what he was doing. The other people were order takers not consultants. I would pass on these guys. read more

Bunch of new windows & a new patio door a decade ago. They used sub-contractors for installation. Many installation problems. Seemingly no insulation & sealing around the 4 sides of the windows. Cold air blowing thru the completely unsealed underside of the patio door frame. At inspection by Nick, he didn't notice the poor quality of the installation, but of course everything was closed up. Over a decade later I still find new problems. Handymen have noticed issues at a glance. I wish I could pull off all the trim around every window, seal everything, and also reinstall the patio door and some windows that are "off". What a mess. I very much regret having done business with this company. See not-recommended review Debbie P. 1/11/20. That is exactly the same as my experience (bad installers, a 3rd guy that occasionally showed up for a couple of hours and knew nothing (seemed like a substance issue), smokers, patio door not sealed on the bottom, no sealant around frames, external noise, cold air from bottoms & sides). I wonder if we had the same team of installers, and how many other Gravina's customers had similar experiences. 11/9 hmm, owners response seems to have disappeared when I edited my comments. That's not fair to them. I will try to "paste" it below. No, I did not contact you. It took years for me to realize how bad the installation was. If I knew that you would fix everything, and that I would not be out of pocket for painting, re-caulking, interior painting & caulking, and probable interior drywall or carpentry work, I would call you. If you agree to do an evaluation free of charge, that's OK by me. On the positive side, I will say that Gravina's did honor warranty and replaced 3 sashes that eventually developed mold between layers of glass. Response from the owner yesterday Sorry to hear that you are not happy with your product and/or installation. We are very curious, did you try to call to discuss the issues with us directly? The concerns you are having don't match anything that our service department is aware of. Seeing as how you didn't have the courtesy to leave your actual name, we don't feel it is fair to leave a bad review. Simply giving a negative review with an alias gives us no chance to resolve the issues you are having. We are one of the longest running window and siding companies in Denver and strive to make sure all our customers are taken care of. read more

Gravina's Windows and Siding came through for us. We purchased a house full of windows from them just over 10 years ago. These were some high end custom windows and we have been happy with the performance and longevity of the product and also the craftsmanship of the install. The reason for this current review is we had two of the glass units seals fail recently and needed Gravina's to deliver on their lifetime warranty offered at the time we bought. Well it took some time to get it done, but they just completed the work. Thank you to Paul who came out to do the work. He was a real pro and did a nice job! Part of the value of working with a locally owned company is their ability to stand behind their work even over ten years later. If you are considering a window/siding company you should give Gravina's a chance to earn your business. read more

I met with a rep 2 weeks ago and placed an order for a few windows and a sliding door. I was told it would be about 8 weeks for completion. They were very quick to cash my check. As of today, nobody from Gravina's has contacted me to do the final measurements so that the windows/door can actually be ordered. Customer service is pretty low so far. I'm giving one more week before I request a refund so I can go with another company. read more

Bought a door in April 50% down, Gravinas said 8 weeks for installation Emailed Gravinas in July (12 weeks) stating how disappointed we were that no one had contacted us about the status of our door. Gravinas says manufacturing delay, now 18 weeks to get door. Emailed Gravinas in September (20 + weeks) now really disappointed no one has reached out to us. Door finally installed on 9/25 (install team did fine.) ONE MONTH LATER, no one has contacted us to do final punch list, trim, and staining. looks terrible and we see it every day. Worst communication from a high end product / service provider. Never proactively communicated with us. Will never recommend Gravinas. read more

My experience with Gravina's goes back to early January, 2019. I contacted them to adjust or fix an Anderson french door that was having a problem with the opening/locking mechanism, and to replace a Marvin double-hung window that had some discoloration between the glass panes. Neither were purchased originally through Gravina's, and both were almost 20 years old. My initial impression was great. Jeff Gravina arranged to come and take a look at the door and window just a few days after I contacted them. He quickly diagnosed the french door as needing a replacement mechanism, and the window with a seal failure. He said he would order the replacement mechanism and suggested I contact Marvin to see if the window was still under warranty. He said that Marvin could send me the two replacement sashes and I could easily install them myself. I called Marvin and learned that the window was out of warranty, that the specific product line of my window was being phased out, but that they had a great relationship with Gravina's and could probably arrange an expedited build instead of the usual 4-6 weeks. However, they strongly recommended Gravina's install them in case there were any problems. I called and spoke with Jeff. He tried to convince me that he didn't need to come back out to do the install, but after explaining what Marvin had said, he reluctantly agreed. I told him that the Marvin rep was willing to expedite the windows and gave him the contact name. Six weeks later I called Jeff to get an update. It took several calls over a period of about a week before I could get hold of him. He said he would look into the status and get back to me. Having heard nothing, about a week later I called again. And over the period of a couple of weeks I tried repeatedly to contact Jeff directly by phone and email, and by through the website contact, and leaving multiple messages on the main Gravina's phone number. Eventually, I contacted someone in sales who promised to get hold of Jeff and get back to me. Over the period of a couple more weeks I spoke with the sales rep and he told me he couldn't get a response from Jeff, then eventually went dark on me as well. At that point I gave up with Gravina's. I hadn't put any money down. I contacted another company, emailed a photo of the sash label to them. Two days later they gave me a quote and I put down 50% for the new sashes. Four weeks later they called me to arrange the install, and three days after that the window project was done. The window company also referred me to someone they recommended who does Anderson french door work. He came out a couple of days after I contact him. I explained the history and the possible need for a new door mechanism. He examined it and said it just needed adjusting and cleaning. He did that and about 20 minutes later I had a properly functioning french door for a fraction of the cost of a new mechanism. read more

Horrible job. Didn't put in foam around the outside of the window and they had to come out to fix the caulking a few times. And now 3 years later while up on a ladder to do some painting, I noticed a 1/2" gap above one window where you can see right through to the outside. No wonder why I kept feeling drafts. read more

This is the classic case of dad building a nice company and son taking over and things change for the worse. Nick (son) is happy to take your money, but less eager on the follow through. Numerous calls went unreturned. The work was sloppy and the headaches were extreme. read more

WORST customer service I've ever encountered! Specifically LARRY - one of the owners who treated me with the most disrespectful attitude I've ever had in my life. Windows were ordered on 3/24 - and the job was not completed until 6/16 - because of their mistakes (they ordered the wrong window for our basement and the wrong color siding). They have very poor follow up and have terrible inter-company organization. They never knew who was out on what job. They also NEVER called to schedule an installation - we always had to follow up with them. But above and beyond everything else - LARRY was the RUDEST person I've ever talked to in my life. The fact that he feels comfortable treating his customers with such little respect and condescending tone. I am appalled! I will NEVER use them again and hope that you do the same. read more

We stopped in the store late May and met with Larry about replacing all our windows. He was nice to work with, very laid back so we decided to go with them. His son Nick came out a couple weeks later to do the exact measurements, he is very argumentative and seems to always want to be right when you are asking questions. I have some friends who used Gravinas and they said the same thing. I was a little worried about it but when the crew showed up they were great to work with, they took all the time I wanted to answer questions and show me how they were being installed. My lead installers name was Gary, I don't remember the other two's names. Sorry guys but thanks!! The job took about three days and they did a decent job cleaning up when they were done. The job was done the 2nd week of June. I have been in the construction industry for 30 years and I would use these guys again. read more

BUYER BEWARE!!!!!!!!! Salesman promised that windows would be installed in 4-6 weeks on 11/6/2014. It is 1/19/15 and the windows still have not been scheduled or installed. I sent an email on 11/17 with a question about my order and I never received a response. I called the office on 1/12/15 and I was told by a lady who answered the phone that someone would call me back and no one ever did. I finally received a call today (1/19/15) from Larry Gravina who told me that he was unwilling to work with my schedule to install the windows, and he threatened to take me to court and put a lien on my house when I told him that I would write a negative review about his customer service and his business. I am surprised that they are still in business treating customers like that. I would not recommend this business, and I will not order doors from them in the future like I had planned. I am going forward with a BBB complaint, and I urge you to stay away from them. They also pay people to write reviews so I would be leery about the good reviews written here! http://www.thedenverchannel.com/news/woman-paid-to-post-five-star-google-feedback ETA* Ask Mr. Gravina whether or not he RESPONDED to my email? Did he call me back when I called on the 12th? NO! If he had, he would have learned that the truck issue became a non-issue a few days after I sent that email. Money is not an issue for us at this time. And, his response to mine and other negative reviews just solidifies and confirms how little he knows about quality customer relations. Look around the internet and you will quickly find many many negative reviews about Gravina's Windows and Siding, all with the SAME THEME: Bad customer service, inability to install in a timely fashion to hold up their end of the contract, and inability to install a quality product and stand behind their work. But apparently this is all my fault, the weather is to blame, his internet server is to blame, his brother is to blame(which he claims is why he didn't call me back or answer my email), and everyone else is to blame except him. hmmmmmmmmmmmmm AGAIN BUYER BEWARE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I wouldn't even give him 1 star if that were an option. read more

We paid a little less with these guys that a few other quotes but the experience working with them was a mess from right after we signed the contract. The salesman communicate with unprofessional super short replies which are never clear and NEVER proactive. I feel like we honestly we never had had our job done if I hadn't asked several times what was happening. In retrospect it's pretty clear what the business model is... Get a sale and then order the materials. After forgetting about the customer for several month scramble to find "some guy" who can come and install it. The "some guy" was good at what he did but showed up and was immediately bitching about working with Gravina as it's "always a mess working with them". He walked off the job after a few days when I went to ask him about how the windows would be trimmed. It was clear that despite three visits to my house the salesman did nothing to create a design or installation instructions/plan. We were then asked to pay more to trim windows as they were somehow unique but it was never clear why the original quote would not have accommodated that other than the salesman not doing his job. The invoicing process is a mess as well. Find a real company to get your siding done. This place is a bunch of bozos just looking to make some money. read more

They always say, hindsight is 20/20. If I knew what I know now when I ordered windows i never would have. The windows seem cheap they do not close properly and never have. The door is so out of plumb you either can't get it opened or have it lock. They had to replace a window at less than 2 years old for damaged sill. Now they are doing the same window in less than 2 years and want to charge for the install. Last they do not show up when they have a scheduled appointment. I got them as a referral and I knew the installer that put those in. Needless to say he is no longer there and they installers now are questionable at best. Buyer Beware! Tim P. read more

First, full disclosure....... I swore I'd never use this company simply because their commercials are painful to listen to. But then I thought it best to give a local company a try. So, I called and talked with Mike, who I believe is a Gravina family member. He said that he had a 3 hour window the next day and thought he could stop for an estimate, but would call to confirm. I rearranged a few items for that day to ensure I was available to meet with him. Well, here we are over a week later and I still haven't heard from Mike, or anyone else from Gravina's. I have since called their competition and had exceptional responses. Oh! And they not only called to confirm, but they showed up too!! Since Gravina's appears to be a dealer/rep for many window and door manufacturer's, I am sure the product is very good. The CS however, I can't even say it's lacking because it just isn't there! If I were a rep for the likes of Anderson windows, I'd be disassociating my company from these guys in a heartbeat! read more

Ugh. Nick Gravina was unprofessional, didn't seem to be familiar with the installation instructions of his product, and seemed to want to blame mistakes on everyone but his crew. I did find the Gravina crew assigned to our project certainly kind, however there were parts of our project where corners were cut, and Nick repeatedly tried to get out of doing the job right. For instance, we had several arch window where Marvin instructions and the sale rep specifically indicated needed they to be flashed, Nick tried to argue (so very intensely) that these windows required no flashing and that the window nailfins alone served as adequate flashing. We also had a french door installed where the crew simply installed the door right over bare wood -- again no flashing was installed at the base of the door. I purchased close to $100K worth of windows through Gravina. We selected Gravina in part because Nick indicated our job was large and he would be present to ensure things went smoothly and provide a high level of oversight to the installation. I believe he was present twice at our house for a total of 30 minutes near the very end of the project. That said, I didn't particularly enjoy listening to his endless excuses, nor did I trust his attention to detail, so that was probably for the better. Finally, I will say that Nick's customer service was extremely poor. When we insisted that our arch windows be flashed according to the Marvin instructions (and the Marvin rep), Nick refused to take our phone calls, and insisted that all correspondence be via email exclusively. This slowed down our project timing, and certainly soured the relationship. However, even though our contract expressly outlined a payment plan of a downpayment, (which we paid before the windows we ordered) and then a final payment at the completion of the project, Nick demanded installment payments because our project ran long. Only when payment was involved was Nick willing to meet with us and talk! Quite simply, it was infuriating working with a person who seemed to approach things only from his perspective. For those with large projects I would suggest looking elsewhere. I tend to think our project was a Saks 5th Avenue project with a Walmart type attitude. read more

Too bad there is not "0" stars. I emailed for an appointment which specified the doors I needed. Salesman called and re asked the question I already put email, but so be it. After he got my address he asked, Is there was a "Mr. B"? I'm not offended easily, but a. it is none of his business, b. it made me feel unsafe, and c. it made me feel like I'd get a better deal if a "Mr." was there to negotiate. I responded, "Does it matter?" He responded, "I just don't want to be shot when I come to the front door." REALLY?!? I refrained from responding, I have a concealed handgun license. The following day he was late to the appointment, but after clearing the air he told me he'd have a bid to me the next day. I didn't receive the bid until 2 days later which only included 1 of the 3 doors. I replied, "thanks but I need the whole bid to make a decision." A week later, I haven't received it. He completely wasted my time. I would NEVER use them!! Plus, I went to the showroom to see the material of the doors he was talking about and most of the product is similar to what is in Home Depot. A waste to drive across town. Truly TERRIBLE. Home Depot and Pella were off the charts better. read more

This is a follow up of my review a couple of months ago. We had serious problems with all of our siding around the windows after only 3 years. I had called Gravinas to ask them to come out and look at our problems. They never returned my calls until I posted a review on Yelp. After our review we received an email from Larry and we sent pictures of our damage. They did not come out and look at our issues, but only stated that from the pictures I sent it appeared that the caulk that they used was not warrantied. Apparently, if you use Gravinas you will need to re-caulk your windows each year. We have now hired a contractor to replace our siding and when he did the demo we could see that the damage was clearly caused from the new windows. Again, I contacted Larry, sent pictures of the damage, and asked that they come look at the problem. There are 1/2" gaps between the OSB and windows with no caulking or filler and inadequate flashing on each of our windows. Our contractor was surprised that the windows would be installed with such large gaps. They have refused to visit our home and look at the damage in person. They claim that the damage was pre-existing. If that was the case, I would certainly expect that the damage would have been brought to our attention prior to installing new windows. That was not the case. In any case, if you use this Gravinas, be prepared for poor customer service, poor workmanship, and a company that does not stand behind their work. Be sure to read the small print and understand that their warranty is, in fact, very limited. read more

If you are looking to buy new windows DO NOT go to Gravina's Windows. I purchased 5 windows and a sliding glass door and they were installed second week of July. Installers rushed to install and never went over anything with me. I purchased double sliders so I could lift out the windows and completely clean them. First problem I could not get the windows out and I also found two of the windows sashes were made to small and if I moved sash all the way to one side I had a gap of about 1/4 inch. I placed a call to the company and left a message with the service desk. I never received a call back so 2 months later, the first week of September I called again, and this time talked to the service person and he told me that he could not return all of the calls he received. Finally got someone to come out to check things out and he made a few adjustments and had to order a couple of new sash's. October and November came and went with no calls. I finally called the manufacture to find out the order would not go out until Dec 1. Finally 12/23/20 they came out to install new sash and correct errors the installers made. I have alarms sensor inside the frame and because the windows were not installed right the sensor could not be moved. Throughout this whole mess their only explanation was it's 2020 and they had too much work and many problems. They never showed any real concern for the customer issues and said they did all they could do. Bottom line I did not know I needed to be a window installer and that I needed to check all of their work. It was bad enough that I had to call the manufacture to get answers. Just save yourself the pain of working with this company and go elsewhere. read more

I ordered a replacement screen from this company over a month and a half ago, scheduled an appointment with Derek to have him come to the house today to install and fix a broken latch on one of the windows. He never showed. Never even had the courtesy to call to let me know he wasn't coming. I call the office and nobody knows where he is at. I have wasted so much time repeatedly calling this company to arrange for the delivery and install/maintenance. Obviously they don't give a rip about the customer. Save your money folks, this is a shoddy window company at best. Call Vivax instead, excellent installs and responsive office support. Another item of note...I had VIVAX replace 3 of the Gravina windows because they had been damaged by painters. The VIVAX installers told me there was little or no insulation around any of the Gravina windows, so obviously they were''t installed correctly. Another warning...don't patronize Gravina. read more
