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!

Do you do glass replacement?

We do not offer glass-only replacement services. If you are unsure if you only need your glass replaced or need complete new windows, give us a call. Our company focuses on full window replacement which means we take out the existing windows and install new windows (frames and glass sash).

LEARN MORE: Window Replacement vs. Glass Replacement

How do you buy windows?

There are four primary considerations when purchasing new windows for your home; the materials used in the frames, type of windows, glass package, and your budget. Think about what you like and want then contact your local window pros to schedule a consultation.

How are replacement windows measured?

We take multiple horizontal and vertical measurements of the window to determine the smallest points of the window as well as the window depth. That allows us to order a properly sized window that’s not too big for the opening and not small enough to leave big gaps around the window frame.
