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!

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."

The windows have done well this far but I have one where the brick mold, part of the window frame, has cracked. Contacted gravinas 4 months ago. Spoke with owner who had me send a text with pictures and told me he would get this ordered. A month went by with nothing. Called and the warranty person there, Tausha, told me it never got ordered, then told me I don't have lifetime guarantee but a limited warranty, I stated nope, I have the paperwork to show this. Then she tells me factory won't cover this but will see what she can do. Then get an email saying they will get it ordered and installed. Months go by, appointments to install keep getting canceled by them, and this goes on for two months. Then finally after 4 months the window guy shows with weatherstripping in his hand! I said that is not what needs to be fixed, he agrees. Call Tausha who tries to tell me that factory recommends installing this weather stripping to avoid more cracking. Umm what? I said that is not what needs fixed and was told you had ordered the brick mold around the window. Her response is "you want the brick mold replaced?" Umm, yes, that's what is cracked! Then she tells me well the warranty doesn't cover that. lol I ask for the owner to speak with him. Puts me on hold for 5 minutes then comes back on saying the owner will call you and come out and look and you guys can talk about it. Great! Well owner has yet to call or show up. Don't get suckered by this company with promises of lifetime warranty just to sell you windows. They lie 1000%! I'm over them, I will fix the window myself or take it out and replace with something better. Worst company to deal with. Constantly lie to you.

From the beginning, communication was prompt, professional, and consistent--something we deeply appreciated after months of delays elsewhere. Their pricing was fair and straightforward, scheduling was timely, and the installation process was clean, efficient, and respectful of our home. This was not a small project either--our custom shower spans more than 9 feet wide--so precision and experience mattered. The finished shower door is absolutely beautiful and exceeded our expectations. We truly could not be happier with the final result and would gladly recommend Colorado Glass & Mirror to anyone looking for quality workmanship, reliability, and excellent customer service.
