Why Choose Texas Buildmart?

At Texas Buildmart, we don’t just manufacture air vent covers, we address genuine design and performance challenges. Our story started over 20 years ago, when a small construction firm, Skuadra Developers, struggled to find contemporary vent covers that matched the quality of homes they were constructing. They partnered with us to develop air vent covers they’d proudly feature in their projects. The positive response from builders and designers was overwhelming. Since that time, we’ve advanced through four generations of product development, consistently focusing on quality, sophisticated design, and straightforward installation. What began as a contractor’s solution has become a trusted brand for designers, builders, and homeowners throughout the United States.
