Love the product and level of service. One downside was material was on back order due to Covid-19 which made the turn around time about 2.5 months. But it was... well worth the wait. The screen door was well made and it closes very smoothly. Plus it cost us about $200 cheaper then from Home Depot.

Sheila C. from Mansfield, TX
I love my new windows! I'm amazed at how much sound & heat they keep out. The installers were quick & professional. Brennan gave me options other vendors didn't take... the time to consider. The quote was exactly what I paid - no price changes! I absolutely recommend Brennan Enterprises for new windows & doors. :)

Frequently Asked Replacement Window & Door Questions

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.

What’s the window buying process like?

The window buying process is easier if you already have an idea of what type of windows you want. Consider how they should work and how you want them to look. Once you have an idea of what you’re interested in, you’ll schedule a meeting with a window consultant to discuss product options, measurements, and installation. After you sign a contract for your project your windows are ordered from the manufacturer and installation is scheduled after your windows are delivered.
