"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."

"I cannot praise this companies work enough. They literally check all the boxes when it comes to a home renovation professional. Clear and timely communication, started and completed the job when promised, very neat and tidy, and did work above and beyond expectations. I would highly recommend them for a egress window install any other services they may provide. As a bonus, their work added $10k to our homes value."

"I did my homework before deciding on where I'd buy my windows. Got three quotes; all very reputable companies. Champion (John) gave the best presentation by far! Very knowledgeable, very detailed with window samples and heat indicators to actually show me Champion windows efficiency. Best price, best financing. Now I know where to buy the next set of windows!"
