Replacement Windows that Fit Your Home

Since 1979, Brennan Windows has been the exterior remodeling leader for the Dallas-Fort Worth Metroplex and the Austin area. We have done this not by being window sellers but by being window consultants. Brennan doesn't only help you find the window to fit the frame, but the window to truly fit into your home's style while providing the best in energy efficiency.

To acheive this we offer a variety of product types, manufacturers and finance options that can be molded to fit your desires, lifestyle and budget.

We know the window buying process can be complicated; that's why we created the Brennan Windows website as a comprehensive window information resource. Whether you need to know the differences between wood and vinyl windows or want to get a dash of inspiration with our Arts and Crafts Bungalow window showcase, it is all here.
