What our customers are saying

We love our new windows! They are a dark charcoal color and they make the home look great. Scott Brennan showed us some great options and we loved working with him. And you will not find a better installer than Howard. We did not have one single issue with the install. We are very pleased.

Landra P. from Arlington, TX

Had a great experience with our complete new window replacement. Many compliments from neighbors. Best decision we made since we bought our house in 1996. Were so happy, we went ahead and also had a new front and back door made and installed. Would whole-heartedly recommend Brennan Enterprises to anyone.

Jay S. from Frisco, TX

I can't say enough good things about this company. From my first call, all the way to installation. They were attentive, professional and prompt. They delivered what I asked for and they went above and beyond to meet our expectations. Use them, you won't regret it.

Dora S. from Northlake, TX

Initially, I had Brennan Enterprises replace some large windows in my house. The windows they sold me are high quality, and they did a great installation job. Soon, I had them come back and replace all the other windows in the house. The windows look and function great.

Brian B. from Southlake, TX

We used Brennan for new windows in our house and went with the Traditions and couldn't be happier! They are very high quality windows and the crew led by Jeremy Delgado did the best work and we're very kind and courteous! Jeremy had to fix up some brickwork that was shortcut during the build and his work was top notch! I will definitely be buying any future windows from Brennan and highly recommend them to anyone who wants quality windows at a fair price!
