The whole window world experience was great. From the initial sales and estimate to the install was stress free and smooth. Steve Bell our salesman was not pushy, the company gave us accurate lead time, and the installation crew lead by Daniel O. was on time,very professional, friendly, and worked very hard. read more

had Mike Cook come over and look at some side bay windows to get replaced. I told him they were not closing and don't think they could be fixed. Mike took a look at them and was able to fix them without being replaced. It took him a little while to figure it out but him being the stand up guy and obviously very honest man he is he was able to do it and did not even wanna charge me but I couldn't resist to give him something. If I ever need windows replaced I'd definitely choose this company in a heart beat. Very honest, professional and courteous which is hard to find in companies these days. read more

TERRIBLE - both the company AND their windows! As a female homeowner who knew nothing about windows, I feel completely taken advantage of and hope to spare anyone else the same terrible experience. I had 19 windows and 10 sills replaced totaling $16,248 and could be more unhappy. READ THE FINE PRINT - if you have any problems and want to sue, your contract says you will pay for THEIR attorney fees. Mike C, the Sales Agent, completely lied when he told me the windows would reduce the sound of street noise compared to what I already had. Unfortunately I believed him and replaced several windows I now realize were superior to these and did not need to be replaced. In fact, my whole home is actually much louder now - I can hear everything through them - even birds! These windows are cheaper than others for legitimate reasons!!! Installation was a nightmare. They trashed my house, made very little effort to protect floors, put their tools down on furniture and scratched it, left dirty gloves on my son's bed, left nails, a saw blade and glass in my driveway on day 1, peed all over the toilet bowl and floor in my bathroom...the list goes on. GM and Owners did not return my emails or calls. Mike C/Sales also wrote "Routed Edge" for the new window sills on the "Installation Checklist" original AFTER I had signed it and been given the carbon copy. This mistake resulted in me receiving a very different looking window sill than what I was replacing and expecting. The Installer tried to cut down the sills and make them work but I am not happy with the end result. See pics. Mike C denied his fraud and a man named Scott was sent to my home during installation and I felt like he was there with the intent to intimidate me. The General Manager Alyse offered me a measly $400 credit after they completely ruined the window sills and when I said they was not enough, and asked to speak to the owners, Rick & Chrissy Rose, I was ignored - that is, until I posted a Google review. Then they added the credit back on to the bill and began threatening me. See pics. And now one of the windows won't even close. AVOID read more

We were told 12-16 weeks and it's now going on 8 months. The customer service desk isn't helpful and downright rude. Steve Bell, the sales rep, is unresponsive and does not return calls or emails within a week. When he does finally reply he is full of excuses and will do NOTHING to actually help his customers. HORRIBLE experience! This place is not worth the little you save! At the time of the contract they said when they received the windows it would take a week to install. They have me scheduled for install in ANOTHER MONTH! The timeline is frustrating for sure but with COVID it is understandable for everything to take a little long than usually. However, my one star review is due to Window World and their sales rep, Steve Bell's rude and awful customer service. read more

Mike, the sales guy was great. I can not say enough good things about the installer Diego. He was efficient professional, and did an amazing job, all in the rain. My window and door look great. With all the rain and hail everything has been perfect. No leaks or anything. read more

I got 3 estimates for 6 windows. Not only did the representative come to the house, he also checked in to give status updates. We were told 10 weeks and excited to have them installed within 4 weeks. The installers were very professional and re-washed windows because they weren't happy with the first time. I have recommended them to my family. read more

ZERO STARS. I purchased a basic, wooden, exterior flat door with no windows or trim, to be painted by owner and hardware provided by owner, November 2021. It was installed 3/18/2022, about a half a year later. It would cost about $300 at Home Depot. It was sold to a single mother asking for the lowest possible price at a huge profit of 1424.19. I have now paid a total of $1764, making consistent payments over the minimum due and am still being charged. RUN DON'T WALK AWAY FROM WINDOW WORLD. read more

I've had my new window and sliding door for a month now and they work and look great! It's a small condo so it was just those two to replace. I already notice a difference in noise reduction and room temperature compared to the old original single pane aluminum frame ones I had. I also got quotes from Renewal by Andersen and Home Depot, and WW not only had the lowest price of all three but also the best warranty. Renewal by Andersen quoted me over double what WW charged me for the same product, yet they have a 20 year warranty when WW's is 30 years! Which really is the better value? Don't get ripped off by Andersen. Steve Bell was the tech who initially came to take measurements and start the order. The guys who came did a professional well done job. read more

Worst warranty policy of all time. The seller of the home has 30 days post sale to call in to Window World and transfer the warranty for the buyer. Like that's going to ever happen. What a scam. The seller who bought these windows paid thousands of dollars and that got factored into the purchase price when I bought the home. "But sorry they had 30 days and you don't have a warranty." I definitely won't be using Window World for any of the homes I build going forward. read more

So I got a refund, they took the door back. This turned into a four month ordeal, my suggestion to you my fellow yelpers is don't use this company. They don't care their products are garbage, their customer service is a nightmare. I ended up going to Home Depot for a real door, Home Depot did an outstanding job read more

So, after a lawsuit threat from both myself, and my HOA, a second set of installers did eventually come out and replace all of the broken trim, the caulking nightmare, and they pulled-out my patio door, and replaced the stud underneath that the previous installers ripped out and didn't replace the first time, which caused my door to start sinking into the ground. These installers were nice, and it looked much better. However, I had to front the expense for all the exterior paint needed to make everything match the condo color scheme again, and I had to repaint in every single room of my home, as well. I did all the painting myself, and spent over $200 for several quarts of all the colors needed. But, there are still issues that I mentioned in emails to Brian, that were never even addressed. Like, one screen was installed with a tear in it, and no one still even wanted to talk about the stud that was also ripped out of my bedroom wall, never replaced, and back-filled with standard caulking, because this "super construction material" aka caulk, would dry tough as concrete, and I wouldn't need a stud, according the the original installers..........uuugggghhhhh........*rubs temples*... Whelp! Whatever!! I'm on the bottom floor of a two story unit! Hope that's not structural! Otherwise, the death of Window World will be from giving it's last dime for property repairs, damaged personal property, personal injury of multiple residents, and vehicle damage, as the parking lot is outside that wall. But, go ahead and ignore it.....sweet.....*thumbs up* Also, the screen door on my patio can never stay on track. Why? Because when the patio door was reinstalled after the structural stud replacement, the door was installed slightly convex (bowing out), so the track is not straight, and the screen will be doomed to come out of its track for eternity. Also, according to the second opinion I got from a different contractor, this slightly convex installation of the door will comprimise the strength of the glass itself, because obviously, there is inappropriate pressure on it. However, when I ask Brian about the remaining things that no one even mentioned, he told me this is the first time he's hearing of any of it. SO, I RESENT HIM ALL OF THE EMAILS SENT WEEKS AGO THAT OUTLINED ALL OF THE THINGS I MENTIONED ACCOMPANIED BY PHOTOS. Maybe, read your messages every now and again! I DID mention all of these things long ago and have proof. But, if I have to see anyone from this company in my home again, I will lose my mind. The simple sound of y'alls voices spikes my blood pressure. I've already personally been solicited by two different law firms about a potential class-action suit. I'm sure some of the others with bad reviews have been contacted, as well. I hope Window World is ready for things to get "real" in a hurry, because it seems the bees nest has been stirred-up all over this city. It's not an issue of "if" they will be legally held reponsible now, but "when". P.S. Saw a Window World ad on Facebook. "Window World cares about Colorado!" Almost died laughing....thanks for that.... read more

The installer was one of the best experiences I've had in a very long time. No complaints, no issues, courteous, professional, understanding and respectful. After first review, the windows appear to be installed to perfection. I will be referring your company in the future. Thank you again read more

What a piece of work this company is. Just a heads up, if you ask then to fix their poor quality installation, they will threaten you with their legal department. The process of getting the windows was fairly seem less. Afterwards....it's been hell. The day of installation, I was unhappy with the quality and I was told nothing was wrong. I then reach out to sales and am told that the quaint was in fact terrible and not the normal way they do business. What a joke this establishment is....spend your money elsewhere. read more

The windows look great and perform well! The installation was the same day. Here's the bad part, they broke a 95.5" inch marble window sill. Their response is it's not their problem per the contract. Can you believe that? They also left glass fragments on the ground in several locations. I'm only giving one star for the actual window. Do not hire this company! read more

Window World of Denver - They even tried to silicone the tile - Windows Installation Near Me - Denver, Colorado

I referred Window World (WW) to another homeowner and he contracted with this business to have 16 windows installed. I was told about an ongoing referral promotion when I had my windows installed. At the time of sale for my referred friend, he was also verbally informed about the referral program. However, it seems WOW does not honor their program and changes the effective dates quite often. He was told by the office manager that his $16,000 sale does not qualify after the fact. I wonder if this is considered a deceptive business practice or if it is just bad business. When I went to WOW's website they have a link and a page dedicated to their referral program with fine print that can be changed at any time. WW it seems like you have had some bad business transactions, now you can add deceptive promotions to your portfolio of bad business. read more

Called me 10 minutes before the appointment to give me an estimate and the guy said they don't want to take liability for replacing my windows since my townhouse has stucco. Confused me since many of my neighbors have had their windows replaced and the companies they used didn't have any issues. If your company doesn't do stucco you should probably make people aware before you schedule an estimate. Gentlemen went on to say that he was going to text a picture to his boss and then call to reschedule if he could replace them. So...guess I'll be happy they called. Waste of time. read more

My best friend had windows put In Her condo. She is a single mom, and deals with a strict HOA. Window world made a complete mess of her home. There is caulking spread all over the place, as though a 5 year old did the install job. She has been trying to get window world to correct the issue, to no avail. I have to replace 3 large windows in my house and will NOT use Window World. BEWARE!!! read more

Where do I begin? Let's start with the sales guy (Mike C.)... pre-contract, I was told window world didn't offer triple pane windows. So I had the double pane windows installed, and the noise in my home is now horrendous. I hear all the traffic from miles around, planes/other aircraft, people conversing in the street - all of which I couldn't hear before the install of window worlds cheap windows. So, I mention the noise problem to the sales guy and ask again about the triple pane windows to verify whether it was an option, and even offered to pay the difference in upgrade price if it was viable. Again I'm told window world doesn't offer triple pane; however, only days later I observe a window world ad on Facebook promoting a free upgrade to triple pane windows (and I took a few screenshots to support my case - attached). What happened here window world? Was your sales guy's commission on the double pane more money? Or maybe there was a backlog of triple pane orders causing your your sales guy's commission paycheck to be delayed? I'll be filing a bbb claim, contacting local news media to save others from your bogus and deceptive sales practices, and I'll definitely be speaking to an attorney. Now let's talk about the install (wow, bad)... the installers caused some minor damage to my exterior siding and made no effort to correct it, even after I brought it to their attention various times. I had to caulk it up/repair it myself. They also severely damaged the metal edging on the interior of two different window sills. They will both need mud, texture and paint (but also needed to be screwed back into the frame. They were left loosely hanging there.). This is A LOT of rework for me to do. The caulking was poorly done overall (at best) and left large open air gaps at the tops of two windows on the exterior, which left me at risk of possible severe water damage to the interior wall of the home. They also left the windows filthy, and didn't clean them even after I mentioned it and asked. To top it off, your sales guy measured the windows incorrectly (he even openly admitted it), and as a result, there was a larger than normal gap between the frame of the home and window frame, likely contributing to the noise problem. I brought it to Mike's attention, and was reassured that he would replace the windows with new ones measured to correct specs if I wanted. So, we replaced one that was measured very poorly with the largest gap, to first see if it would help with the noise, before deciding to replace all the windows. Now it seems replacing the other windows is no longer on the table as previously promised now that they've been paid. Moot point tho right? I wanted triple pane to begin with. Just more deceit. The sales guy gave me a $200 personal check to cover some of the damage, but it wasn't nearly enough to compensate me for the lies that led to an overall massive increase in noise, a less than quality install of cheap windows, and damage caused by Window World's installer's blatant disregard for my home. Save yourself the time, money, anxiety and heartache, and avoid Window World at all costs. Go with anyone else but window world. I wish that I did, and would do anything to give their crappy windows back for a full refund for the opportunity to hire a quality contractor with a good reputation that would have done a quality job and used quality windows. This is just the beginning of my reviews. I'll be contacting consumer alerts on local news stations, I'll be leaving Facebook and google reviews, and I'll be sure everyone I come into contact with is made aware of this terrible experience. I've attached pics of the damage to my interior window sills, demonstrating the level of rework I'll have to do, and pics showing the gaps they left on the exterior. I've also left a screenshot of the ad for free triple pane upgrades. Window World, you should be ashamed. Sincerely, Dana R. read more

Contacted the company twice requesting an estimate for a window installation. (77x71 triple pane low-e) Both times I was promised a call from a sales rep to discuss the project at hand. Not one call from the promised sales rep has occurred. Not able to recommend this company due to the utter lack of follow-through and customer service. Avoid. read more

I've had a really great experience working with Window World. Robert was the salesman and put NO pressure on me (unlike Champion... ick) to buy but was ready to answer all my questions. When I said I was nervous about a poor install job (after reading some scary reviews), Robert said they've been working on training and improving the quality of their installers and, to make me feel at ease, he would personally do the installation to make sure I felt comfortable. And, he did a great job (along with Diego). I'm super happy and my new windows are a huge improvement to the house! read more

We had a roller-coaster of a ride with this company. Our first sales guy didn't show to our first appt, which is inconvenient to us because we took work off to be there. After days of not hearing from anyone, they finally called back to say the first guy quit and they were behind and to give them another chance. The second sales guy came out and was very helpful and professional. We ended up attempting to schedule an install and never heard back. We called back in and got a recording saying they are busy. Finally got someone to call us back after a weeks time. They scheduled our install. We loved our installer and he did a very good job. He was on time and did all 4 of our windows in about 6 hours. We also love the look of the windows and the quality. Pros: very reasonably priced, very nice windows, friendly staff, great installation Four stars for a rocky start but quality install read more

Tried to get a quote on a window for a 4-unit property in Denver and was told that they required the owner to be at the property (I live in California). I've never had a contractor require my physical presence - I often pay electronically and in advance of work to avoid any problems with being out of state. The sales person would not even discuss the issue - must be nice to be able to turn down work. I can only imagine how poor their follow-up service must be once they have gotten the work. Property Owners Beware!!!! read more

Getting new windows installed from Window World was a pretty smooth transition, shon the sales representative came over to my house to give me an estimate gave me a sample of the windows that they will install and a pretty good presentation. I had to think about it for a couple of days but in the end decided to go with Window World.shon said it could take up to 8 weeks to get the windows installed at first it's look like a long time but guess what 4 weeks later my windows are installed... Edgar came in this morning right on time and started working, him and his partner work quietly and efficiently they were done in about six and a half hours, installing 5 windows and a new sliding door for the patio. They made sure to clean after the job was done and left the place spotless. Thank you Window World for a job well done read more

I ordered 4 windows from Window World of Denver. The day they showed up to install, I was informed that two of the windows were measured incorrectly and would not fit. They installed the two windows that did fit. After 7 more weeks of waiting for my two casement windows, the day finally came for install. The installers did not wear masks in my home. After the installers left, I noticed the windows did not have the factory NFRC labels on them, which seemed suspicious. I got no care instructions, just a "sign here" single page when they were done. The glass (viewable) area of the windows were a full 4" smaller horizontally and 5" smaller vertically than my previous casement window! The company claims that this is because they are a replacement window and without considerable modification to the window bay, they needed to be smaller. These windows look ridiculous next to the full-sized windows they were meant to replace. There is a full size window that I didn't replace right next to the new window, and the new one looks like a toy next to the original window. It has an excessive amount of trim around the window (they even had to double up the trim on the top). The WORST part is I WAS NOT TOLD THAT THE WINDOWS WOULD HAVE A MUCH SMALLER VIEWABLE AREA THAN MY PREVIOUS WINDOWS! If I was told that they would have a much smaller viewable area, I never would have had them installed. Thank God I didn't do the entire house, or my house would feel like a cave. To top it all off, one screen had a hole in it, the glass was dirty on the outside when they put them in, and the bright white trim on the outside of the windows was darkened to a grey with dirt upon installation. DO NOT USE THEM! Period. I requested a 100% refund. Take your toy windows back, I don't want them on my home. Are you listening Window World? So much for 100% satisfaction guarantee. read more

On 5/14/2015 I scheduled a 4 window installation thru Brian Goldberg for Monday (5/18) @ 8:30am. Later that day Chesia from the office called me to reschedule for another time on Mon. because, according to her, the installer had a doctor appt. that morning. Between 12:30pm and 1:30pm became the agreed upon new install time. Well, the installers did indeed show up on the 18th ... eventually ...@ 4 in the afternoon. LOL. I asked the guy when he arrived "Well, how did it go at your doctor appointment? His response ....."What appointment?" They did end up installing 3 of the 4 windows. They couldn't install the last because evidently they don't have enough sense to carry a long enough ladder on their vehicle to accommodate a 17 ft high window installation. The 4th window is still in my garage as I am writing this. I called WW this morning to try to set up another install date but Chesia said the scheduler was busy at the moment and took my number. Haven't heard back from either of them. I emailed a complaint to Brian Goldberg (scheduling) as well as Vivian Price (sales). Haven't heard back from either of them. I'm certain that I'll hear from WW sooner or later. Why? Because they want to get PAID. LOL. Pls. allow me to offer up my 2 cents worth of advice .... If you expect even a minimum amount of competence WW should be the very last on your list. AMENDED REVIEW: Rick, the owner of WW, was kind enough to respond to an Email that I sent this AM complaining about the service or lack thereof I was getting. He assured me that the last window could be installed either this afternoon or early tomorrow morning. So I have set up an install appointment thru Brian for 8:30 am Fri. Hopefully this gets resolved tomorrow. Because of his quick response to my complaint and his sincere attempt to make things right, I don't believe this incident should reflect negatively on the company as a whole. Actually they do very good work and I am more than pleased with the look of the windows that were installed. In retrospect, I may have jumped the gun in submitting a negative review .. but when a business doesn't call back in a timely manner, it does seem as if some of their employees (not all) are taking their customers for granted. I am upgrading WW from 1 star to 4 stars. read more

Yesterday my kitchen blind literally fell out of the window. It should of because it was only held by screws into a thin piece of wood by the previous handyman. I thought it was from the new Window World installation. From the initial call to WW yesterday- the office manager, Alyssa was eager to help and sent out Scott, the service manager to remedy the situation. They were friendly, prompt and their customer service was great. Call them for any window needs. :D read more

- Edited at the end - I had a very disappointing experience with Window World. I spent $11,000 to have some windows and sliding glass doors replaced. I was at first pleased with the speed at which my windows were ordered and scheduled for installation and the installers themselves were also quick to get everything finished in one day but that's where things stopped being good. The installers were not careful and scratched up the brand new windows and doors in several places, chipping the white coating off of the framing in places. They also left smudges and smeared silicone on the outside of the windows in places that I cannot get to from the outside, basically leaving me with permanently dirty windows. They rendered my alarm system inoperative by pulling the sensors out of the sills and filling in the holes with silicone, leaving them dangling with 6" to 12" of wire hanging out. I will have to call the alarm company and pay to have all of the window and door sensors fixed. They left scratches on the exterior of my house where pieces of the old windows hit the outside during removal and when dropped from above then hitting side of house. They also dragged dirt into and throughout the house with their dirty work boots, taking no precautions to keep carpets clean from boots. They even left spots on carpets trailing out of the house from old windows dripping. When I called the company to complain about these issues, they told me all these things are normal and to look on the back of the contract where it is explained that they are not responsible for alarm systems. There is a difference between not being responsible and going out of your way to make something inoperable. All they had to do was not pull the sensors so far out and not fill holes with silicone and I could have reattached the sensors myself but now I can't. This lack of quality and care may be "normal" for Window World but it is not normal in my opinion. They did at least offer to provide a window cleaning service but, when I accepted the offer, they did not respond and the windows have not been cleaned. Based on my experience, I would not recommend Window World to anyone that cares about quality and customer service when choosing a replacement window company. -- Update -- When I wrote this review, I gave only 2 stars but have upped it to 3 because the window cleaners the company offered have since come out and made the windows look much better to look through and one of the windows that was damaged on the outside has been fixed by the company. I appreciate that the company at least took those actions. I would now consider recommending them to others but would warn them, or at least prepare them, for what to expect during installation and to not have their hopes up for a 5 stat job. read more

Window World is the best! My old sliding patio door was REALLY old, and the handle broke. Window World gave me the best price for a beautiful new door.

My new door works like a dream! Thank you, Window World! read more

The windows i ordered was taking too long its covid I understand so I called to cancel they responded with they are keeping the deposit so the response i got back was from the most unprofessional angry lady threatening to sue me for the rest of money owed and that I must delete my reviews so I did and now here an updated review. The manager I believe called me very angry at me and instead of trying to be nice and work things out I was threatened. I agreed to do the windows and pay the rest I just want the world to know what kind of leadership works there. The installer was good and salesman was good its whoever lady called me and threatens its customers should not be there is my opinion. read more

After receiving several "energy hog" letters from Excel Energy, I had Window World come out to do a free energy audit and estimate. The energy audit was informative and told me what I had suspected, my windows were drafty. They said my 20 year old wooden windows and sliders used caulk as insulation which tends to disintegrate after 5 years, thereby letting air in. They use a fiberglass insulation instead. I liked their professionalism and bid so I booked them to do my first floor windows and sliders. The crew was courteous and tidy, leaving no mess, which was a huge plus for me. My new doors and windows make my house look new again. I recently received my first Excel bill after the new windows and it showed a little over a 20% savings. I can't wait to have my second floor windows replaced! Thanks Window World. It's refreshing to work with contractors of your caliber. Sincerely, Angie R. Louisville, CO read more

I purchased my Window World Windows about 8 years ago. I was originally looking for tilt sash windows. The salesman told me that their tilt sash windows sometimes howled in high winds. Since I live in a high wind area I was told to go with the windows that lift out of the frame for cleaning. Since most of my windows are 48x72 inches, they are very heavy. I sacrificed this ease of cleaning so that I would not end up with howling windows. Fast forward a few years, the windows begin to howl when opened partially If I opened them all the way, They did not howl. Fast forward a few more years, open the window for some air and they howl ALL the #*! ing time!! They also get foggy. Called window world because they have a Lifetime Warranty. NOT!!!! It's not worth the paper it is written on. Can't turn on the whole house fan to cool my room because I have to listen to the windows howl. So sleep hot or listen to windows howl. Thanks window world. Worst product and customer service ever. read more

My windows were installed in December 2015. The windows themselves are great and my home is much more quiet and warmer in the winter. However, the install quality was less than desirable. After the installers left I had to vacuum broken glass out of my carpet. There was snow on my patio during the install so I did not notice the broken glass the installers left covering my patio. I am grateful that neither of my dogs nor I stepped on any of this broken glass before I was able to discover and clean it up. Last week I discovered that the installers did not completely caulk around one of my windows and yellow jackets built a nest in there, allowing easy access to the inside of my home TL;DR: I love the windows, installers cut corners. EDIT: I was contacted by Window World after my review and a manager came out the same day to review the install and address my concerns. I feel that my concerns were taken care of and I have updated my rating to reflect this. read more

I purchased windows from Window World Denver about 5 years ago. I was happy with the installation and quality of the window. Before purchasing them, I had several other companies give me an estimate. After considering the quality, price, Good Housekeeping Seal, and the warranty, I did not see how I could go wrong. I have had to use the warranty 3 times. I had a screen that did not fit properly. There was no argument, they came out and ordered a replacement. 1 year ago moisture showed between the glass on a window. Again, I called, no hassle, no argument, they ordered new glass, called when it was ready, replaced the window no charge. I called last week as a window would not stay up. Zack King came out this last Monday and replaced a few parts. Again no hassle, no charge. I have recommend them to 2 neighbors and they are also happy. My brother in Longmont is getting an estimate on 2 bay windows. All I can say is my experience has been great. Thank you for the great product, and outstanding service after the sale. K.

Just got my new windows installed and I LOVE them! I got triple pane, double hung & some side sliders. The security features - being able to vent the windows at night & not worry about someone getting in - are exactly what I was looking for. The salesman, Mike Cook, was very knowledgeable, and I really like that they are transparent about the cost unlike other window companies I met with. You know exactly what you are paying for. Roberto and Diego installed them and did a fantastic job! Seriously, they are perfectionists. The work was great, they showed me all the amazing features of the windows, and they cleaned up everything. I would definitely recommend Window World to anyone looking to upgrade their windows. read more
