Wesley J. from Frisco, 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 had a great experience from beginning to the end. The installers left the area cleaner than they found it! ;) The sales lady was extremely knowledgeable and super friendly!... I never felt pressure to purchase anything, but I ended up buying several picture windows that overlooks my pool area. I absolutely love my new windows, and they've proven to be energy efficient! I would really love to replace all of the rest of the windows, in fact, I hope they reach out to me and make me a deal that I can't refuse! I highly recommend Brennan Enterprises!
