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!

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.

Amari was friendly and patient, walking us through the different options and offerings. I was sold! This was the third window quote I'd received, and I really appreciated the straightforward pricing and easy financing options. It took about three months from our initial meeting to installation. On install day, it was super cold and the crew worked efficiently, cleaned up quickly, and communicated well throughout the process. The supervisors kept us informed of their progress and were happy to answer any questions. It's only been a few days, but we haven't had any issues so far. I'd definitely recommend talking to Performance Windows if you're considering a window replacement.

K&G did a good job completing my James Hardy cement fiberboard siding. I got two other estimates…read moreand K&G solutions was the best deal. They were one of the better, well-known competition with advertisements, but they gave me an estimate that was 33% higher! On top of that, they weren't fully forth coming about the financing. They used high pressure sales techniques, saying "if you sign up now on the spot, we can give you 0% financing." However, they didn't tell me that the financing company charges a 20% loan fee. They just hid that fact. Greg, the owner of K&G, was upfront, honest and very direct. He told me directly the breakdown of the cost. He even negotiated with the same financing company and I got a lower loan fee. If I had the cash to pay for for the whole project upfront, I would have had the option to save even more money. It was nice to know what everything cost and to know that I had the option to pay cash if I had it. Greg sent about 6-7 guys come out and complete the whole job in only 4 full days from tear down to brand new siding installed. The competition said they would only send out two guys and take a full two weeks to get the same job done and charge me way more. I'd rather the company hire more men, and get it finished quickly instead of having 2 guys go at a snail's pace to complete my home. Not only was Greg able to get my siding done much cheaper and get a lower loan fee, but was able to have a new window installed in one of my bathrooms, which had no existing window. Greg was able to include the cost of installing a brand new window and new siding for much cheaper than the competition. Also there was some small corrections that needed to be made and Greg was able to take care of that for me. K&G, thank you very much for taking care of all that needed to be done on the house.

The mark of a great company isn't just price or online reviews -- it's how they handle things when…read moresomething goes wrong. I hoped K&G's reputation would hold up when we hit a snag. Unfortunately, it didn't, and Greg (the owner) fell well short of the standard I expect from a vendor with real character and integrity. First, I can't say enough good things about our installers, Jerry and Jacob. They were talented, respectful, detailed, clean, and professional from start to finish. You'd never know new windows had gone in -- that's how much pride they took in the work. They deserve five stars on their own, and if you go with K&G, ask for them by name. You won't be disappointed. That's where the good part ends. Our windows were installed in February 2025. One window and one screen arrived damaged, and we were told replacements would follow quickly. What actually happened was a year of wrong-sized orders, repeated excuses, and no real accountability from the owner. Eventually, Greg connected us with the distributor directly, and a representative there finally sourced the correct window and screen. That resolution was completed on July 24, 2026 -- nearly a year and a half after installation. We held up our end throughout: paid on time, worked around K&G's scheduling, and stayed patient far longer than we should have had to. The pricing was fair, and the installation itself was excellent -- that's the only reason I'm not giving this one star. But no customer should have to wait over a year for a replacement part. I can recommend Jerry and Jacob without hesitation. I cannot recommend the ownership's follow-through or customer service.
