We offer a wide selection of windows and doors designed to match or complement the style of your home. Our experienced design consultants are specialists in helping you explore the best options—whether you want to maintain your home’s existing look or discover new possibilities to elevate its design.

Window pricing varies because no two products or companies are exactly alike. Differences in brands, materials, and energy efficiency features, customization options, installation expertise, and even vendor relationships all influence the cost. Additionally, some companies may not include key factors like labor, warranties, or additional fees in their initial quotes. It’s important to compare quotes carefully and consider the overall value—not just the price—when making your decision.

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.

We’re seeing an increasing number of clients request casement windows and large multi-slide patio doors. Both options help homeowners achieve clean sightlines and maintain energy-efficiency.
