Ratings & Reviews for Brennan Enterprises

We chose Brennan Windows from the great reviews we read and they really delivered! There is a reason they have so many 5 star comments. Frank Peters was great to work with and helped us along the way as we had never replaced windows before. It's harder than it seems! They have a super nice and professional team of people that help to keep everything organized. John, their installer was great as well. We found Brennan to be great to work with and highly suggest you contact them first for your windows. You'll be glad you did.

All windows replaced same day, lead technician was very helpful and easy to work with, love my new sound insulating, differential pane thickness windows!

Purchased Anderson 100 series windows and an Anderson 16' French Door with glass panels. Had Brennan install door unit. Very satisfied with the delivery and a great crew on the installation.
