Our Happy Customers Love The Zen Experience

"I hope this review saves someone a lot of time and trouble. My house had garbage windows that had gotten dirty from the inside and could not be cleaned. I got a bid from Renewal by Andersen to replace them all. $28,000!!! (and this was for their more affordable product line). I got a bid from Home Depot. $18,000. Zen Windows came up with a bid very quickly. As promised, I didn’t have to listen to a lengthy sales presentation or suffer a salesman in my house for hours. Their bid was just over $12,000, and the windows seemed to be at least as high quality as the ones offered by the other two vendors. I am not a contractor and should not be trusted to judge the quality of window manufacture, but my house is now warm in winter and cool in summer and much quieter too.

The windows they put in seem just great and I am very happy with them. I got the ones that are triple-paned and they seem to offer much better insulation (both sound and temperature). The installation was very smooth and these guys treated my home with care and respect. My home had some unusual features (three, odd-shaped architectural windows in the living room) and these guys handled it quite well. I wish I got to write more reviews like this one. These guys were great and I do not hesitate to recommend them."
