“Ryan was very helpful and answered all of my questions about building a home addition.
Definitely the best remodeling company in San Antonio!
Melanie
“We reached out to dozens of contractors and ultimately decided to go with GTex to rebuild and restore our home. It was the best decision we could have made because GTex rebuilt our home into something out of our dreams.“
Desiree G.
“I can’t recommend Ryan Gabriel and the GTex team enough. As an architect for 20 yrs, I’ve worked through many house remodels and new construction builds. I was prepared for a lengthy and complicated experience, full of surprise expenses – that’s the norm for many homeowners at this point. GTex was exactly the opposite, and I’m so thrilled that I worked with them for our home remodel.“
