“We have worked with Roger L. previously and were well aware of his excellent work. We purchased a Century Home that needed all new windows and doors. Roger traveled 1-1/2 hours to quote us. We did get other quotes before Roger/Clera Windows arrived and we were very please that Roger’s bid came in lower. We replaced 19 windows and 2 doors keeping with the character of the home. Work was done quickly and efficiently. Roger and his team made this experience pleasant. We are thrilled with how the new windows look and the insulation factor is fantastic.” -Mary V

“Sales, quality, pricing, timing, and installation all were excellent!

Renaud was very knowledgeable about the windows in our home (original from 1962). He took the extra precaution to have the installer come by after our initial quote to ensure the work could be done the way he had told us – without damaging our walls. They did the job (13 windows plus a front door) over 2 days. The installers were polite, efficient, and professional. Best of all, it was only 4 weeks from payment to INSTALLATION!

They look amazing, and they even put in a door handle we purchased on our own. They went beyond my expectations for cleanup in and around the home. One installer even raked up some of the debris. We are very, very happy.”  -Karen Rose
