Our redesigned website is on the way. In the meantime, here’s who we are.
Don Young Company (DYC) was founded in Dallas in 1978 and has spent nearly five decades doing one thing exceptionally well: engineering and manufacturing high-performance aluminum and vinyl windows and doors built to stand up to the most demanding climates in the country.
We build in both aluminum and vinyl. Our thermally-broken aluminum is a best-in-class approach for hot Southern climates, delivering strength and slim, architectural sightlines, while our energy-efficient vinyl systems offer lasting performance and value. Every window and door is designed to perform through Texas heat, driving rain, and pressure.
Today, DYC operates from its Dallas headquarters and manufacturing facility alongside four branches across Texas and Oklahoma. We supply contractors, wholesale distributors, custom homebuilders, architects, and dealers across Texas, Oklahoma, and Eastern New Mexico.
That same commitment to quality has kept DYC trusted by the homeowners who live behind our windows every day, since 1978.
Premium performance isn’t a finish we add at the end, it’s built into every frame from the start.
