35" x 59" Single Hung Window

Most projects are completed in just one day. Our small, experienced crews typically install 8–10 windows per day and work one opening at a time, carefully measuring each opening and window as they go. This approach minimizes disruption to your routine while ensuring precise, professional, high-quality results.

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.
