Report
We had two ProVia doors installed by Brennan Enterprises. The product is truly exceptional. Our front door is beautiful; it is fiberglass, but it is nearly impossible to distinguish from a wood door except that it is much more energy efficient. I love that there are no more cold drafts in the winter. It made a huge difference during the big freeze in DFW. The installers did a great job insulating around the frame. There was a small issue with a blemish on the newly installed frame, but Brennan Enterprises made it right. The whole process took awhile, but it was worth it.

Brennan did a fantastic job with our new sliding glass door and windows. Not only are they beautiful, but they function and reduce noise so much better than our previous ones. The installer, Jake, went above and beyond. Thanks, Brennan!

I am very pleased with my new windows. The installers, Clayton and Daniel, were very careful not to damage the window frames and the paint surrounding the windows. I was pleased they put a drop cloth
in front of the window they were installing and they vacuumed after the entire installation.

Great experience with Brennan. They communicated well throughout the process and installed all 5 custom windows in one day. The installers were professional and cleaned up after. I'd definitely recommend Brennan.

Brennan is top notch and did an outstanding job from ordering to installation! Peter professionally installed my two Pro Via doors and 30 windows. Everything looks wonderful and he pays a lot of attention to detail in the installation to include clean up. I highly recommend Brennan!

We recently contacted Brennan about a window whose seal had broken. After a few emails to ascertain the facts involved, they quickly ordered the replacement pane. They came out and replaced the pane in a very timely and professional manner. The installer was friendly and competent. It was a very positive experience.
