"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."

"We had the main windows done by Power Windows in 2021 and now we had them do the windows on our outbuilding and mudroom. The entire process has been great from start to finish. The windows are fantastic, keeps the heat out in the summer and cold out in the winter. The sales(Davis, Jack, and Brad) and work crew(headed by Gus) have been very up front and professional. I highly recommend this company."
