What our customers are saying

Excellent Service & Products! Technician's craftmanship was fantastic. Looking forward to using them again! I had a new storm door installed.

Doug

These guys are the best. They installed the most beautiful, high quality door for me. And they were so patient with me. I will use them forever.

Jules

We love our new windows and doors! We should have done it years ago. We highly recommend Brennan Windows and Doors!

Brennan was able to replace our custom windows and entry door. They were even able to get a duplicate of the half moon window above our entryway door. Their work looks great and the price was very reasonable.
