After having experiencing contractors in the past that had left us feeling frustrated, disappointed…read moreand taken advantage of... It has been a breath of fresh air to work with Gravina's Window Center of Littleton. We had tried going the route of "finding a great deal" in the past, only to discover cheap is expensive in the long run, and our "deals" had left us with poor quality products and even worse quality workmanship. We decided this time around we would research and interview for all of the projects we were about to begin - this time it would be about finding the best value for our money, professionalism, quality and workmanship. Our first meeting with Gravina's was to look into replacing a few basement windows. After meeting with Jim Gravina, Mike Gravina and Justin Shyong - loving their energy, knowledge and ideas - we decided to have them replace the windows in the basement and replace our back patio doors. I can't begin to express how excited we were to see the finished project - the back door had become a favorite focal point of our home! Once we had actually seen, and experienced the difference with the windows, door and workmanship from Gravina's, it was a "no-brainer" to have them handle "phase two"... siding our garage and replacing the garage windows. Again, everything was awesome! Knowing that our James Hardy siding was done according to all of the proper guidelines of the product was important to us. Of course, with everything going better than we could have expected, I can honestly say, we were excited to hire Gravina's again for "phase three"... replacing the windows and front entry door on our main level (the remainder of the house), they continued to exceed our expectations and we are absolutely ecstatic about everything! John Gravina and his crew did an incredible job with our window & door installation, as well as Wynette & Samantha who had come back to do perfect staining of the interior windows, door and casings to match the hardwood floors in our home. It seems a little strange to say I was excited to work with a contractor - because I think many of us have experienced that nightmare of having someone in your home and just praying for the day they will leave - but the peace of mind knowing that things are going to be completed right, all of the proper follow thru will be done, having qualified and respectful people working in your home, knowing that you have a company you can trust, and knowing you will have beautiful windows, doors and siding to enjoy for years to come, is something to be excited about! Upon writing this review, I have reached out to Gravina's to let them know if they have a client that would like to see the work they have performed at our home, they are welcome to schedule a time with me to bring them by (this is something that we have only offered to do with Gravina's and Luxescapes, the landscape/hardscape company we worked with on our backyard that was also incredible). Because I don't want to post my personal contact information over the internet, if you wish to call me regarding our experience with Gravina's, you are welcome to get my number from Gravina's. If you are looking for windows, doors or siding, I would highly recommend contacting Jim, Mike or Justin to come by... you will not be disappointed! We hope you will find this information helpful in your search for a qualified contractor for your project! ~ Kevin & Jeri-Lynn ~

If I could give zero stars, I would. Our windows were ordered last Fall (September) and they still…read morehaven't been installed. My husband has called several times to find out why. He usually has to leave a message, and no one returns our call. We were told that our windows would be installed in December. The last time my husband spoke to anyone, he was told late April/early May. It is now May 10th. It's been 9 months. No one has ever called us to inform us why it is taking so long. I assume the ball was dropped somewhere in the process. I want to cancel the order and forget it. I chose this company based on a personal recommendation. I thought we would get better customer service over the corporate options. Nope; it has been THE WORST CUSTOMER SERVICE we have EVER received. DO NOT hire this company. 9 months and counting.

We were looking to replace our 28-year-old, builder-grade siding that was showing signs of water…read moreretention. After getting four quotes, I came to realize that each company pretty much has one type of siding they recommend and install. For one company we interviewed it was LP (engineered wood), for two companies it was Hardie (fiber cement), and for the last company, Superior Industries, it was a material we hadn't heard of before: Gentek ALIGN Composite Cladding (aka Alside ASCEND Composite Cladding). I was initially skeptical because I hadn't come across it in my research. How good could it be? Turns out, amazing. Really glad I called Mike to come take a look, as otherwise we would have ended up spending a lot more to get a not-quite-as-good product. Superior Industries replaced all of our siding, soffits, and facia, and aluminum-wrapped all new trim boards for us. They did precise, high-quality work and it really shows. Communication was good throughout and the guys who did the work were friendly and competent. Mike only has a couple teams, so these guys have been with him for many years and really know their stuff. They listened to everything I had to say, they consulted me when there were any decisions to be made, and they answered all my questions. Everything looks great and we are very pleased.

Inferior Product Installed…read more I needed new windows for a remodel I am doing in my daughter's condo. I contacted Superior Industries for one of three quotes I received. Mike came to respresent Superior. Mike and I discussed in detail about the color of the windows. I probably told Mike at least a dozen times "I need brown windows," "The windows must be brown." Not once did Mike speak up to tell me the windows he had in mind would be white inside. I fully expected the windows to be brown inside and out. Mike emailed me a work order where he added "white inside" to the description of the windows. I didn't notice this detail in the work order, but at the same time, I did not approve or sign-off on this work order. I approved the install solely on the promise of brown windows at a quoted price of $11,262. What business person would believe that simply sending out a work order, with no sign-off by the customer, indicates acceptance by the customer? The windows Superior installed are much cheaper windows than all-brown windows would have been. I accepted their quote believing I would get all brown windows. Quotes from the other vendors indicate brown and white windows sell for three to four thousand dollars less than all brown windows. I overpaid by three to four thousand dollars! I entered into agreement with Superior in good faith. I did not get respect or good faith in return. Instead, I got an inferior product where a much better product was promised. I will never do business with this company again. Update to Mike's response: What contract? A contract is a document where both parties sign-off agreeing to the terms of the contract. My signature does not appear on any such document. The email Mike references approves only the quote based on a promise of seven brown windows. I never approved the work order via email. I challenge Mike to post here any proof that I signed-off or otherwise approved the terms of his "work order."

Extreme disappointment regarding the quality and installation of the 18 Simonton windows I…read morepurchased from JDI. The overall product quality is unsatisfactory, and the installation was subpar. I continue to experience drafts and excessive noise through all the windows. The amount of noise I receive from planes (I live nowhere near an airport) and cars is crazy; it was never like this with my old builder grade windows. Furthermore, the caulking is very sloppy. The owner said he was ok with the work and threatened to place a lien on my property the day after the windows were installed if I didn't pay, even though I was not satisfied. Following the owner's suggestion, I completed a Home Energy Audit. I have attached a few photos from that audit which clearly demonstrate significant temperature differences. I have also attached videos demonstrating the air leakage using a fog machine.(I can't attach all the pictures and videos I have and would be happy to share) After I called the troubleshooter radio show, the owner sent a crew to insulate three of the windows that I felt were the worst (which helped a little). I was then asked to pay for the insulation of the remaining windows. It is unclear why new windows would be installed without proper spray foam insulation in the first place. Additionally, two of the windows still do not close or lock correctly, even after the sashes were replaced twice. Given my significant investment, this has been a regrettable experience.

Replacing Our Interior Doors From the start, Kale came to…read moreour home and gave the sales pitch of a lifetime, from selecting the style to the color and explaining the process from beginning to end. He shared that it would take about 4 to 6 weeks to receive the doors. In addition, being a military veteran, Kale ensured that we received a military discount. Several days later, another employee came and digitally measured all of the doors that were going to be replaced. The big door was going to be 96" across, which was for our den storage closet. He explained the process for this door and what to expect. Five weeks later, our doors were received and installed. The team of two came prepared and installed all the doors within three hours. Talk about professionalism! The doors finish was outstanding, and the black enhanced the white doors. The storage closet, which was 96 inches across, was awesome. One of our neighbors was looking at the work and wanted their phone number, which I gladly gave to them. Living in a retirement community, we do a lot of word-of-mouth referrals for our neighbors. And I'm gladly going to spread the word about this company and their excellent service.

The windows look beautiful installed, the install and surrounding areas are clean and tidy, and the team is professional. I got a handful of quotes and Window Doctor beat them all on price, lead time, quality reviews, and knowledge (such as needing tempered glass near entry ways to be up to code). Each window has an individual QR code to scan if service is needed in the future, which I find to be nifty. Overall an incredible local Denver family company to work with!

He was very friendly and did an excellent job getting the project started. Joe and his crew came for installation.

They did a wonderful job the windows look and operate per and we couldnt be happier. Rare these days when something like this actually goes as well as it possibly could have. And to top it off their pricing was more fair than anyone we got quotes from. I would highly recommend them!

We got an old security door and a problematic screen door that no handyman could install correctly replaced by DSD, and they did a great job on both. They remove your old doors, and they'll dispose of them too. You don't realize what a difference a modern, clean storm door can make on the look of your house until you do it, and then you wish you did it sooner. Not only does DSD use only high quality doors, they align them perfectly and make sure that they're calibrated to close at a speed that works for you and will securely keep your door closed. We used to have a significant draft on both our front and back doors, and our new storm doors fit so perfectly that those issues are completely gone. Also, the doors open and close quietly, while adding security to our home. Could not recommend these guys more. If you've been wondering if it's worth going outside of Lowes or Home Depot for a screen door, or you're looking to get a security door without spending a fortune, give Denver Storm Door a call. They are the perfect Goldilocks for most homeowners.
