Foundation & Masonry Crack Repair in San Angelo, TX

Not every crack means your foundation is failing — and not every crack is harmless. The value of a crack inspection is knowing the difference before you spend money or lose sleep.

Cracks are the most visible — and most misread — foundation symptom. A hairline in the drywall might be nothing. A stair-step crack marching up your brick veneer is telling you something moved. The problem is that from the outside, homeowners can't always tell which is which, and the internet is full of both false alarms and dangerous reassurances.

Here's the honest framework we use:

  • Likely cosmetic — thin hairline cracks, stable over time, common in a home's first couple of years as it settles and as drywall and paint cure.
  • Worth watching — cracks up to about a quarter inch that aren't growing, with no displacement. Often manageable, but worth documenting.
  • Structural signals — stair-step cracks in brick or block, cracks wider than a quarter inch, cracks with one side higher than the other, horizontal cracks in a foundation wall, and any crack that's actively growing or paired with sticking doors and sloping floors.

The crack itself is a symptom. Sealing it without understanding the movement behind it is cosmetic. We diagnose the cause first, then seal — so the repair holds instead of reopening next season.

Warning signs

When to call about foundation crack repair

Stair-step cracks in brick or blockDiagonal cracks that follow the mortar joints in a stepped pattern — the classic sign of differential foundation movement.
Cracks wider than a quarter inchWidth matters. Cracks you can fit a coin or a pencil into signal real movement, not just surface shrinkage.
Horizontal cracks in a wallA horizontal crack across a foundation or basement wall is the most serious pattern — it can indicate lateral soil pressure. Get it looked at promptly.
One side of the crack higher than the otherVertical displacement across a crack means the two sides are moving independently — active movement.
Cracks that keep coming backA crack you've patched that reopens is telling you the underlying movement was never addressed.
Cracks around windows, doors, and cornersCracks radiating from the corners of openings concentrate the stress of a flexing structure.

Seeing two or more? It's worth a free inspection to catch the cause before it spreads.

Our approach

How we diagnose and repair cracks

Inspect and classify the crack

We examine width, direction, displacement, and pattern — and check for the companion signs (doors, floors, exterior brick) that separate cosmetic cracking from structural movement.

Trace the cause

A structural crack has a driver: settling, heave, drainage, or soil movement. We identify it, because the crack is the last thing to fix, not the first.

Inject and seal

For appropriate cracks, we use epoxy or polyurethane injection to seal and, where structural, bond the crack — restoring integrity and keeping water out.

Repair masonry and brick

Stair-step and mortar-joint cracks in brick veneer are repaired and repointed so the exterior is sound and the repair isn't an eyesore.

Stabilize if movement is active

If the inspection shows the crack is a symptom of ongoing foundation movement, we address the foundation itself — with slab or pier-and-beam repair — so sealing actually lasts.

Why it matters here

Why do cracks show up so reliably in the Concho Valley? Because brick and mortar are rigid, and the clay-loam soil under the house isn't. When a wet year swells the soil under one corner and a drought year shrinks it back, the rigid veneer has to give somewhere — and it gives at the mortar joints, in that telltale stair-step. The crack is real, but it's a messenger. Reading the message correctly is the whole point of the inspection.

Answers

Foundation Crack Repair — questions we hear

Is a crack in my brick a foundation problem or just old mortar?

It can be either, and the pattern tells the story. Random crumbling mortar is usually age and weathering. A clean, diagonal, stair-step crack that runs through both brick and mortar in a consistent line points to foundation movement. We'll tell you which you have.

Can't I just caulk the crack myself?

You can seal the surface, and for a truly cosmetic hairline that may be fine. But if the crack is caused by movement, caulk hides the symptom while the cause keeps working — and it reopens. A quick inspection tells you whether DIY sealing is enough or whether you'd be papering over something bigger.

How serious is a horizontal foundation crack?

Horizontal cracks are the pattern we take most seriously because they can indicate lateral pressure against the wall rather than simple settling. If you see one, it's worth an inspection sooner rather than later.

Will the crack come back after you fix it?

If we only sealed it and ignored an active cause, it could. That's exactly why we diagnose the movement first. When the underlying cause is addressed, a properly injected and sealed crack stays closed.
