I live in the Harvey Park neighborhood of West Denver where the original 1950s windows are aluminum…read moreframe crank style windows that are very drafty and transfer outside noise into my home. JDI gave me outstanding options for replacing my windows at a great price. I did not get their premium windows. I just went for their second tier basic windows. The entire process from the initial consultation, measuring and ordering windows custom made for my home and installation was roughly 6 weeks. The owner who conducted the initial consultation, scheduler, crew foreman, and crew members were fast, efficient, cleaned up the demolition of the original windows beautifully and were very friendly. Some were even born and raised in the same neighborhood as me. I can't believe how nice these windows are, how they have improved the beauty, air tightness of my home for drafts, temperature changes and for outside ambient noise reduction. Their ease of use is outstanding. I can't say enough superlatives about JDI. I would give them 10 stars if I could. 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.

We hired Five Seasons last year to replace most of our windows for our home. Some of our windows…read morewere fairly large, and we also had two sliding glass doors replaced. So, this was a big project and we were very nervous as it was our first time doing this. From the start, we were impressed by the sales process. They went over our preferences and needs multiple times, made many iterations, and finally, we settled on the windows to replace, the style, the amount of sun filtering, etc. We chose Marvin windows as the window manufacturer, and Five Seasons then handled the installation. Now that it's been a year, we can say that Five Seasons supports their work really well. We had some problems with the hardware side of some of our Marvin windows and doors. It wasn't anything major, but things that should have been working properly. Dylan and Makayla provided exceptional support and actually rebuilt our sliding glass door locks for us, and since they did their work, the door locks have been working perfectly. The window installers, under Mike, did a great job installing windows that were large and in difficult locations. We have now had a year to see how they have held up to wind, rain, and cold weather and they are doing great. We are glad we went with Five Seasons. They were reasonably priced, installed the windows when scheduled, and have been providing excellent support.

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.
