Alpha Construction Firm handles foundation repair and slab work for San Antonio homeowners who can't afford to guess. Foundation issues are the kind of problem that looks small on the surface and turns into a full structural crisis if the wrong contractor gives you the wrong diagnosis. Our licensed crew comes out, assesses the actual cause of the problem — soil movement, poor drainage, settling — and gives you a written estimate that explains exactly what needs to be done and why. We handle pier leveling, slab crack repair, void filling, and new slab pours for residential and commercial properties across San Antonio and surrounding communities.
Your Go-To Team for Foundation Repair & Slabs
At Alpha Construction Firm, we know that foundation problems don't fix themselves — and the longer they go unaddressed, the more expensive they get. Our licensed crew diagnoses the issue correctly the first time and gives you a clear, written plan before any work begins. Here are our most in-demand foundation services:
1. Pier & Beam Foundation Leveling
Why Clients Choose It: Uneven floors, sticking doors, and visible cracks in your walls are all signs your foundation is shifting. Pier leveling stops the movement and restores your structure to level — before the damage spreads to the rest of the home.
Best Fit For: Older San Antonio homes on pier and beam foundations showing signs of settling, sagging floors, or structural movement due to soil expansion and contraction.
2. Slab Foundation Repair
What Sets It Apart: Most San Antonio homes sit on concrete slabs, and our crew specializes in diagnosing and repairing slab cracks, voids, and settlement issues using proven methods that stabilize the foundation without tearing up your entire property.
Perfect For: Homeowners seeing cracks in interior walls, floors separating from baseboards, or doors and windows that no longer close properly — classic signs of slab movement.
3. New Slab Pours
Why It's Essential: Whether you're building an addition, a new structure, or replacing a damaged slab entirely, a properly formed and poured concrete slab is the foundation everything else depends on. We do it right the first time so you're not dealing with it again.
Perfect For: New construction, garage slabs, room additions, ADUs, and any project that requires a properly engineered concrete base before building begins.







Alpha Construction Firm has been serving San Antonio homeowners and businesses with a Texas contractor license, a trained crew, and zero subcontracting on your job. From roofing to foundation repair, we've built our name one completed project at a time — and every job we take on gets the same level of care as the last.
No two properties are the same, and we don't treat them that way. Whether you need a full custom build, a kitchen remodel, or a foundation repair before things get worse, we assess your specific situation and build a plan around it — not a one-size-fits-all package.
If your roof is under 10 years old and damage is isolated to one area, a repair is usually the right call. If it's older, has multiple problem spots, or you're seeing interior water damage, a replacement will save you more money long-term. We'll inspect it and give you an honest recommendation either way.

A bathroom remodel usually runs 1–2 weeks. A full kitchen remodel is typically 3–5 weeks depending on scope — cabinet delivery, countertops, and tile all affect the timeline. We give you a projected schedule before we start so you're never guessing.
