When a local window company gave us an unusually high estimate to replace our fogged up, hard to…read moreslide patio door, we checked out Yelp for a better company. We found great reviews for JDI Windows. Rex, the owner, came out to do an estimate, and it sounded reasonable. His service manager Casey came out to measure. He estimated 6 weeks for the door to arrive. 6 weeks later on the dot, the installation took place. All appointments were scheduled and conducted on time with highly competent, efficient and friendly employees. Casey and Mark arrived, covered the work area and carpet, and two hours later we had a new smooth operating, clear see-thru, sturdy sliding glass door in place. We were very pleased with the door, the cost, and the entire installation process. JDI Windows is highly recommended. 10 Stars. JDI WINDOWS 720 427-4477 Thank you!

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.

Also started the bid process with Costco's provider, which proved to be high pressure and a more expensive fiberglass option, which wasn't a fit with my needs. WD Sales guy Derek was friendly and fair, and answered all of my questions. Install crew, including one of the owners (Joe) was prompt, professional, friendly and fast. The windows look great and I can already see a huge improvement in my energy use. Also love the fact that I'm supporting a local company: they are experts at what they do.

Mike and the team at Superior were really great to work with. We received quotes from 2 other…read morecompanies in the Denver area, but when Mike visited I knew they were the right fit for us. He felt both genuine and knowledgeable, and that proved out over the quoting process and engagement. While the wait for our windows took a little longer than we had hoped, Mike was really responsive and when the window did arrive installation was scheduled immediately. I'd wholeheartedly work with them again and recommend them to others!

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.

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.

Our 1973, 168 condominiums were in dire need of siding to include all the details needed to create watertight, functional, and attractive condominiums. Prior to choosing WestPro, we did our due diligence. We identified and sought proposals from several contractors held in high esteem, to include WestPro. West Pro provided us with a fully understandable, highly detailed proposal covering all contingencies to include an offer to assist in financing the cost of this significant project for our community. Jordan spent hours with us patiently and carefully explaining what was needed, the value of James Hardie Siding and what WestPro will provide. WestPro has been and is one the most professional siding contractors in the industry. From initial contact all the way through our completed project, the team at WestPro was highly communicative. Throughout this recreation of our community, Jordan and Clay frequently met with us onsite to make sure that all contingencies were addressed and met. In certain instances, specific needs were identified by Jordan and Clay that did not fall under the original scope of work. Jordan and Clay immediately provided solutions and mitigated the challenge typically without additional cost to our community. West Pro expertly provided high-end customer service experience is second to none. Personally, as a 4-generation, real estate development, construction, and reconstruction family business, I have never experienced a contractor like WestPro. WestPro surpassed their promises and provided us with a product that is more than we ever hoped for. WestPro is a top-notch, professional, and trustworthy organization. WestPro's performance, work and product was excellent in all regards. Personally, I recommend WestPro without reservation. On behalf of our Golden Pines community and our BOD, we highly recommend any commercial or residential property owner to hire WestPro and experience first-hand WestPro's integrity and knowledge about the proper siding installation techniques that will benefit the long-term quality of their exterior siding. WestPro will be very responsive to any or all your needs! Jordan, Clay, Nick, Patrick, and team thank you for increasing the market value of our community and transforming our community to a beautiful Golden offering!

I've had WestPro come quote the same job twice, once in 2023 and once in 2025. It was two very…read moredifferent experiences to the point of being hard to believe it's the same company. The job is for removal and replacement of soffits, fascia, gutters and downspouts on a 1-story ranch with 200 linear feet of gutters. In 2023 a woman came out, did the walk through and then sent me a quote with details about the materials, a cost breakdown for each part of the project - quantity and cost for removal of gutters, removal of downspouts, installation of gutters, installation of downspouts. It was very professional (I work with contractors and job bids for a living) and provided all the necessary details of the cost. In 2023 they refused to address the soffit and fascia so I declined to move forward with them. In 2025 a man came out, did the walk through and then insisted on setting up a follow up appointment to walk through the project quote. I did not receive the info packet ahead of time and was disappointed by what I received - a detailed project description for siding work (presumably for the soffits and fascia but the material was specific to siding installation which isn't relevant to either of those locations) with no scoped quote for any aspect of the project. There were no details of the materials to be used or breakdown of the cost specifics. The dollar amounts were hand written into a spec sheet of "good / better / best" (photo attached because I don't even know what to call it, it's definitely not a job quote). I understand that materials costs have changed significantly and the job might cost more today than two years ago, but if you're going to waste my time with a second meeting to quote the job, actually quote the job. So your experience with WestPro may entirely depend upon the person you randomly end up with as your project coordinator. Homeowner be wary. I'll update this review when I've heard back with legit quotes and decisions on a path forward. For now it's a very unimpressed meh.
