The installers were great
The installers were great. Cleaned up after themselves. I was disappointed with the damage in some of the screens that were installed. Now waiting for the new ones to come in. I think that this should be looked at before scheduling install to make sure all is 100%.

Excellent experience!
They were on time, very neat, explained how they were installing the windows, replaced all the rotted wood on the outside, both men were very pleasant. Everything the salesman stated at the time I signed the contract was exactly the same at the time of installation. No surprises except the windows went beyond my expectations. Also every part of the window has a lifetime guarantee.

Top-notch job.
Our whole experience been nothing but wonderful from Trish She was absolutely great explained everything that we needed to know, and afterwards if we needed her to answer a question, she would get right back to us. And I can't say enough about the installers they came out. They were friendly introduced themselves. Kept my house clean. I think it was cleaner when they left than when they showed up lol. We couldn't be happier with the job. Update had my windows inspected today, by the town. The inspector was very impressed with the quality of the install. He said you have no problem recommending.Who ever did this excellent job

9 window 2nd floor installation, Noank, Ct
Your salesman Bob Schein knew his products well. He was also friendly and very personable. The 3 man installation crew were great, finishing the 9 window 2nd floor job in one bitter cold day. Hats off to this group of workers!
