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!!!!!

Very reasonable pricing and availability very good. Obviously, very knowledgeable and professional- we had a glitch in that the old door was a custom size and we were replacing with a standard size (slightly shorter) door. Dean assessed the situation and had an excellent solution which he was able to implement without delay. He came prepared and handled the problem professionally. The installation took less than a day. They kept the worksite clean and left it the way they found it. We are very happy with the job and will call again for any window needs we may have. Definitely would recommend!

Kat was super responsive to all of my emailed questions and the company as a whole was super reliable (showed up when they said they would, took as long as they would, etc.) They also have you pay for the windows directly so there's no markup there, just the cost of labor. Very transparent. On top of everything they are the nicest people! Highly recommend.

I tried hard to get the owner to come to my house to take a look at a blown out window but had to…read moretry many times. He finally came over and I was excited that I finally found someone who could do the work and was pleasant and price conscience. He presented me with an estimate for the window repair and I immediately agreed to the price and let him know. That's where everything stopped. I waited and waited and waited even more for a call back with an estimate but my numerous calls, texts and emails were never answered. I finally sent an email asking for his advice on window repair versus replacement and he emailed me back basically telling me what a bad idea we were thinking of, but he never gave me the courtesy of even a short email saying he was too busy to take care of the repair of our windows, especially the one that was blown out by the wind. Summit county has very few people who do the work the owner does, so I totally understand he was too busy, but why did he not respond to my repeated texts/ calls/emails so I could just move on and find someone else? When I agreed to the pricing I figured he was at least interested in doing the work and we were willing to wait. I also had a house full of other windows needed adjusting, so it wasn't like this job was too small. I eventually had to go out of county to find a reputable service but I would have contacted them much sooner had I figured out the owner did not want my business. Unfortunately I had to have his business removed from my realtor's recommended service providers because I could no longer endorse the company. I am disappointed that so many contractors and service providers don't give potential customers the courtesy of a quick text or email saying sorry, they have plenty of work and don't want extra work. Maybe some day these folks will need the work and I won't be using them. If you are looking for window repair or servicing in the Summit County area, look further west to the Vail Valley or Eagle area. Summit County has so few, and the one I thought was the best fit is unresponsive.

There is no extra "trim coil" at the top to fill the opening. (note: some trim coil is required around any window frame along with insulation and sealant.) I am updating my rating to 4/5 to account for the trouble I had convincing them this was the right thing to do. Kudos to Lifetime Windows for ultimately replacing this at their expense. I will report the same to the BBB. FYI, nobody asked me to update my review. I only want to be fair and complete. The windows they sold me are very nice.

They are an excellent replacement for our original. We got an estimate from another window company, and it was TWICE the cost of CCE's estimate. This is January 2025 so weather is not good. It was a factor in the length of the installation, but it went very well, and the windows look great.
