Houston Window Replacement You Can Count On

We’re a Texas-based home improvement company that’s been helping homeowners upgrade their windows and doors since 1979. We’re known for our expert installation, top-rated products, and a pressure-free approach.

We’re local! Our headquarters is in Arlington, Texas, close to where we were founded. Since 1979, we’ve worked with homeowners across the Texas Golden Triangle. We’re not a national brand, franchise, or private equity–backed. Brennan is a true Texas treasure and we intend to stay that way for generations.
