Who We Are

A Trusted Name in
Northwest Houston

GT Holdings & Construction was built on a simple belief: every homeowner deserves a contractor they can fully trust. We serve Cypress, Spring, Tomball, Klein, Champions, The Woodlands, and surrounding communities.

When hurricanes battered Houston and the February freeze tested every pipe in the city, our team was there — not just as contractors, but as neighbors helping neighbors recover. That's the standard we hold ourselves to every day.

Integrity

Transparent pricing, honest timelines, no surprises.

Precision

Every detail matters. We measure twice and cut once.

Community

Northwest Houston isn't just where we work — it's home.

Care

We treat your home the way we'd treat our own.
