Customer Testimonials

I can’t say enough good things about Rex and his team at JDI. Rex (owner of the company) was the third quote I got on my windows and I’m sure glad I waited on his estimate before going with one of the other guys. Not only was he the only one that actually broke down the quote into line items for me to see what was the raw cost of the materials, the labor, his profit margin, but he was also the cheapest! Now, rest assured, I was not just looking for cheap on this window replacement. I really wanted top-quality to reduce the draftiness and give me a significant reduction in my heating bills. The Amerimax windows that JDI sells are superb. Locally made in Colorado (an added bonus to support local manufacturing) which means that they have the correct amount of Argon gas for our high altitude. They came in on schedule (was estimated 4-6 weeks and they came during week #5), and despite a small delay due to subzero temps in early November, the installation was handled seamlessly by Darrin and Tony. Top-quality work all-around. No reason to look elsewhere or to spend 2-3x’s as much money with one of the big-name guys. Go with Rex and JDI Windows for your window replacement job!

I wanted to express my 100% satisfaction with the job JDI Windows did providing and installing our new windows. From the owner, Rex, to the installers Lee and Joe, they all displayed the highest professional work during the entire process. I would recommend them for anyone considering a window contractor!

Really enjoyed every member of the team. The crew finished installing windows in one day, caulked the next. Everything went smoothly. Great job!

Kelly W., Facebook

We had a large amount of windows replaced in our home. Their price and honesty were second to none. They followed up with is when we weren’t getting our homeowners to respond to our request and got the windows ordered and put in place in less than a month. They guys that came out to do the install did it in less than 3 days and did a great job. I would highly recommend them.

Rex with JDI blew away the competition. Excellent service, price, and quality. The windows are beautiful and he was able to have them installed before anybody else could and he beat all other bids. I cannot recommend these guys any more highly. I use to install windows and the crew that did mine was a professional prompt and put the extra finishing touches on the windows. Thank you, JDI my house looks awesome!

JDI just replaced 4 windows at my house and I’m very happy with the results. Within a few weeks of contacting them the windows were measured, ordered and installed. Rexford and his guys were very professional and took the time to make sure everything was installed perfectly. I’d definitely recommend JDI to anyone.

Brian S., Home Advisor

I can’t believe how warm my house is since they did the work, and they did it in such a timely manner and they were just the best out of every company we looked at. I’m just very, very thrilled that I will be saving some money on our heating bills as well as the tax-deductible.
