Local, Woman-Owned, and Proud of It
Sage FX Foundation & Construction was built on a simple idea: homeowners deserve honest answers, quality work, and a company that stands behind it. As a woman-owned, family-operated business, we bring that standard to every project across San Antonio and the Greater Austin area.
We understand the unique challenges Texas climate and soil pose to residential foundations. Our certified technicians bring extensive expertise and genuine care to every job — from a single pier to a full house leveling.
When it's a big, dusty job, we send cleaners afterward. When you have a question, a real person answers. That's how we've earned five-star reviews and built lasting relationships with our neighbors.
Our Values
Honesty First
We tell you the truth about your foundation — even when it means less work for us. No scare tactics, ever.
Quality That Lasts
Proven methods, premium materials, and a lifetime transferable warranty on every repair we make.
Treated Like Family
Real people answer the phone, walk you through the process, and clean up like it's our own home.
