The Window Source of Houston is a veteran-owned and locally operated window and door replacement company proudly serving homeowners throughout the Greater Houston area. Led by owner and U.S. Marine veteran David Mallette, the company was built around a simple philosophy: provide quality products, professional installation, fair pricing, and an exceptional customer experience without high-pressure sales tactics.

The Window Source of Houston believes a replacement window or door is only as good as the installation behind it. Their experienced team focuses on the details that help protect a homeowner’s investment, including proper preparation, high-quality materials, careful installation, and thorough jobsite cleanup. Their installation standards are designed specifically with Houston’s demanding heat, humidity, heavy rain, and weather conditions in mind.

From the initial consultation through final installation, customers receive straightforward recommendations, clear project pricing, and knowledgeable guidance to help them choose the right products for their home and budget. The company offers a wide range of energy-efficient replacement windows and doors designed to improve comfort, curb appeal, efficiency, and long-term performance.

As a locally operated business, The Window Source of Houston understands that its reputation is built one homeowner and one project at a time. The entire team—from the office and sales staff to the installation crews—is committed to treating customers’ homes with respect and standing behind their work long after the installation is complete.

At The Window Source of Houston, the goal is not simply to replace windows and doors. It is to provide Houston-area homeowners with a better overall experience and an installation they can feel confident about for years to come.
