Trusted local pros: the trades that work alongside a foundation

A foundation problem in Williamson County rarely stands alone. Here are the other trades you may need — and, because we don’t take kickbacks to name names, exactly how to find and verify a real one yourself.

We deliberately don’t publish a paid list of “preferred” vendors. The value of an independent opinion disappears the moment money changes hands for the recommendation. Instead, this page tells you which trade solves which problem and links the official Texas license lookups so you can confirm anyone you hire — whether we referred them or you found them — is really licensed, insured, and in good standing.

Structural / geotechnical engineer (P.E.)

The most important call you can make. A licensed professional engineer assesses whether you need repair and specs the scope — and because they don’t sell repairs, the read is neutral. In Texas the engineer is the only licensed party the job legally requires. Verify: look up any engineer on the Texas Board of Professional Engineers & Land Surveyors (TBPELS) license search.

Plumber / under-slab leak detection

On active clay, an under-slab plumbing leak is a common hidden driver of movement — and a pre-repair plumbing test can save you from lifting a house over a leak that just re-breaks it. Plumbers are licensed in Texas. Verify: the Texas State Board of Plumbing Examiners (TSBPE) license lookup.

Drainage & grading contractor

Often the cheapest real fix. Correcting grading, extending downspouts, and installing area or French drains keeps moisture even around the slab — sometimes solving what looked structural. See our drainage guide for what each system does. There’s no statewide drainage license, so lean on insurance, references, and a written scope; many foundation crews handle drainage too.

Masonry / brick repair

After a lift, stair-step cracks in brick and separated mortar joints usually need a mason to close cleanly. Bring them in after the foundation is stabilized, not before — repointing a wall that’s still moving just cracks again. No state license; verify insurance and ask to see recent local work.

Electrician & HVAC (when movement reaches the systems)

Significant slab movement can stress conduit, gas lines, and condensate drains. Electricians are licensed in Texas — verify through the Texas Department of Licensing & Regulation (TDLR), which also handles A/C and other trades. Ask for the license number and check it.

Trim carpenter / handyman (the cosmetic finish)

Doors that need rehanging, trim and crown that opened at the seams, drywall touch-up — the last-mile cosmetic work after a repair. No license required; use insurance and references, and confirm with your foundation contractor whether cosmetic repairs are already included in their scope so you’re not paying twice.

How to verify anyone — in five minutes

Whoever you’re considering: (1) get the exact business and license-holder name; (2) run it through the relevant board above; (3) ask for a certificate of insurance and call the carrier to confirm it’s active; (4) read recent, local reviews on their real Google Business Profile — watch for a site claiming “100+ reviews” whose actual profile shows a handful; (5) get the scope in writing. Our contractor vetting guide has the full checklist and free lookup links.

Where we fit

For the foundation work itself, we match you — free — with up to three independent local crews so you can compare quotes by method, pier count, and depth. We’re not a contractor and we don’t perform work; you contract with and pay whoever you choose, directly. The point of this page is the opposite of a pay-to-play directory: hire the right trade, and prove to yourself it’s legitimate before you authorize a dollar.
