"Next time you walk by an egress window on one of these flipped homes - check out the workmanship - crooked, leaking glue out the sides, certainly no permit. I know this because I have witnessed it AND I called one of those "cheap" window people for an estimate (notice how they are ready at the drop off a hat and then drop out of sight when there are problems? The window placed by Egree Inc is perfect. Was it more expensive - not much more than as egress window placed in 2013 that was equal in quality. It was also permitted, inspected, and sits level without leftover glue seeping out the sides. Was there a wait time - not more than I would expect from any quality provider. I was kept informed on the timeline and the window was completed as promised. BONUS - the workmanship is guaranteed and the company will be around to stand behind the workmanship. Excellent work."

"JDI did an excellent job on my windows, I'd gotten pressured into a contract with Champion windows and Rex acted quickly to educated me about industry practices and ultimately helped me get much more for my money that I would have otherwise gotten. Rex's crew was great to work with and did a great job, everything went as expected, and I love my new windows. Would highly recommend JDI windows and have already recommended them to friends and family."

"Very nice to work with. The crew did a great job. I always imagined that getting a new window well would be incredibly expensive and a huge disruption. Not a all! I hardly knew the crew was there. And no hard sell on new window well. He gave me options and information"
