Seeing cracks in your walls or floors? Doors and windows that stick or won’t close right? We repair concrete foundations in Austin before small problems turn into expensive ones.
Austin’s clay soil expands and contracts with every rain and dry spell. Over time, that movement puts real stress on your foundation.

We work on foundations across Austin every week and we know exactly what this soil does to concrete over time. Do not wait until the damage is worse. Call us at (512) 337-4425 today.

Last spring, we got a call from a homeowner off Menchaca Road in South Austin. She had noticed her back door sticking for almost a year. She figured it was humidity. She figured it would work itself out. By the time we got out there, what started as a simple crack injection job had turned into a multi-pier repair. The bill was four times what it would have been twelve months earlier.
We are not telling you that story to scare you. We are telling you because we have seen it happen more times than we can count — and we would rather you call us early.

Warning Signs Your Austin Home Has a Concrete Foundation Problem
Most Austin homeowners don’t catch foundation problems early. They catch them when a door won’t close, when a crack shows up on a freshly painted wall, or when their real estate agent flags something during a pre-listing walkthrough.
By then, the ground has already been moving for a while.
Austin’s black clay soil — locals call it “black gumbo” — is the main culprit. It swells when it rains. It shrinks when it dries out. It repeats that cycle every single season, directly underneath your slab. Homes in East Austin, South Austin, and the Manor area that were built on filled lots tend to settle unevenly — and those signs show up faster.
Watch for these inside your home:
- Diagonal cracks in drywall, especially near corners of doors and windows
- Doors or windows that stick, drag, or won’t close the way they used to
- Floors that feel uneven or slope toward one side of the room
- Gaps forming between walls and the ceiling or floor
Watch for these outside:
- Cracks in brick, concrete, or mortar on the outside of your home
- Water sitting near your foundation after it rains
| Our take: That sticking door the South Austin homeowner ignored for a year? That was her foundation telling her something. A single hairline crack is usually not a panic situation. But a sticking door plus a drywall crack plus water pooling near the back of the house? That is three signs at once. That is a phone call. Austin’s “wait and see” approach almost always costs more in the end. |
What Causes Concrete Foundation Damage in Austin Homes
People ask us all the time: why is this happening to my house? It is a fair question — and the answer almost always comes down to one of four things. Knowing which one applies to your home is how we find the right fix the first time.
| Cause | What’s Happening | Where It’s Common in Austin |
| Expansive clay soil | Swells when wet, shrinks in drought — pushes and pulls your slab constantly | Pflugerville, Kyle, Manor |
| Poor drainage | Water pools near your slab, softens soil underneath, causes uneven settling | South Austin, East Austin, citywide |
| Tree root intrusion | Live oak and pecan roots grow under slabs, displace soil, stress edges | Central Austin, South Congress area |
| Plumbing leak under slab | Slow leak erodes soil for months before any visible sign appears | Any home with older plumbing |
On drainage and Austin’s weather cycle:
As KSAT reports, saturated soil swells like a sponge after heavy rain, only to shrink back down when things dry out. In Austin, that swing happens hard and fast. One dry summer followed by three inches of rain in a week puts enormous stress on a slab that has been sitting on contracted ground for months.
| Our take: Live oaks are everywhere in South and Central Austin and we love them — but their roots do not care about your foundation. If you have a mature live oak within 20 feet of your slab, it is worth having someone take a look. We have pulled roots out from under slabs on Bouldin Creek properties that nobody saw coming until a corner started sinking. |
Foundation Repair Methods Used on Austin Concrete Slabs
Not every crack needs a pier. Not every sunken slab needs to be torn out and replaced. Here is exactly what we use — and when we use it.
| Method | Best For | How It Works | Timeframe |
| Crack injection | Hairline cracks, water intrusion sealing | Resin injected under pressure, fills and bonds the crack | Cures in 24–48 hrs |
| Mudjacking / slab leveling | Sunken slabs, trip hazards, uneven sections | Small holes drilled, foam or slurry pumped under slab to lift it back | 1 day |
| Pier installation | Sinking corners, badly misaligned doors and windows | Piers driven down to stable rock below the clay layer | 2–5 days |
| Drainage correction | Foundations where water pooling is the root cause | Regrade soil, install French drains or downspout extensions | Varies |
A note on piers in Central Texas:
Piers in Austin have to reach stable limestone or pre-Cambrian rock — usually 10 to 20 feet down depending on your location. Our crews know the geology here. We do not guess on depth and we do not cut corners on it either.
A note on drainage:
We almost always pair drainage correction with structural repair. Fix the slab but leave the water problem, and the slab will move again. That is not an upsell — it is just how Austin soil works and we will always be straight with you about it.
| Our take: Foam lifting lasts longer than slurry in Austin’s conditions — full stop. If you are getting mudjacking done by anyone, ask them which material they use and why. We use foam for most Austin-area jobs because it holds up better through the drought-flood cycles we deal with here. |
What to Expect During Foundation Repair at Your Austin Home
The number one thing Austin homeowners ask us before a job: Can we stay in the house?
Yes — in almost every case.
Staying home during repairs:
- Exterior pier work — crew works outside, your indoor routine stays intact
- Crack injection — may need to move furniture in one or two rooms for a single day
- Mudjacking — one day job, most families are back to normal the same evening
How long does it take?
| Method | How Long It Takes |
| Crack injection | Half a day |
| Mudjacking / slab leveling | 1 day |
| Pier installation | 2–5 days depending on pier count |
What happens to your yard:
We need access along the foundation perimeter for most jobs. There will be some disturbance near the slab edge. We restore grade and sod when the work is done — we do not leave your yard looking like a construction site.
When to schedule:
Spring and fall are the best windows in Austin. Summer drought pulls moisture out of the clay and leaves soil contracted — not the ideal time for structural work. We also know how to work through Austin’s caliche and limestone layers, and we build that into every project timeline so there are no surprises on day three.
| Our take: If you are a work-from-home family — and a lot of Austin folks are — exterior pier work is genuinely low disruption. We have done full pier jobs on homes in Travis Heights and Cherrywood where the homeowner was on Zoom calls inside the whole time. You hear the crew outside. That’s about it. |
Foundation Cracks in Austin: Which Ones Are Serious and What Insurance Covers
Two questions come up in almost every conversation we have. Here are direct answers to both.
How serious is your crack?
| Crack Type | What It Means | What To Do |
| Hairline crack under 1/8 inch, no displacement | Usually cosmetic — normal settling | Take dated photos, monitor over time |
| Diagonal crack wider than 1/4 inch or with vertical displacement | Structural concern | Call for a professional assessment within days |
| Horizontal crack | Most serious type — lateral soil pressure pushing on foundation wall | Call immediately |
| Stair-step crack in brick or block | Differential settling — seriousness depends on how fast it is growing | Monitor closely, call if it is growing |
| Our take: Horizontal cracks are the ones that get our attention fast. That is soil pushing sideways against your wall — not just up and down movement. If you have got one of those, do not schedule an appointment for next week. Call us today. We have seen horizontal cracks on East Austin properties that needed same-week attention and we will always tell you honestly which category yours falls into. |
What does homeowners insurance actually cover?
- Soil movement or settling — NOT covered under standard Texas homeowner policies. This is the cause behind most Austin foundation issues.
- Sudden events like a burst pipe under the slab — may be covered
- Accidental water intrusion from a covered source — may be covered
The Texas Department of Insurance confirms that soil-movement exclusions are standard across Texas homeowner policies. Do not wait on insurance approval before scheduling an assessment — get eyes on the foundation first.
Before you call your insurer:
- Take dated photos of every crack you can find
- Get a written assessment from a licensed contractor
- Do not start repairs before you have everything documented
If you are selling your home:
Texas law requires foundation disclosures before a sale. Known issues that go undisclosed create legal liability for sellers. We provide written documentation and post-repair photos ready for your disclosure packet and lender review.
| Our take — the pre-sale story: We got a call from a homeowner in East Austin who was two weeks from closing. Their buyer’s inspector flagged a diagonal crack and standing water near the back of the slab. The buyer almost walked. We got out there within 48 hours, assessed the situation, completed the repair, and provided written documentation in time for the closing to go through. That deal nearly fell apart over something that had been sitting there for years. If you are planning to sell, get us out before you list — not after an inspector finds something. |
How Long Foundation Repairs Last and What They Do for Your Austin Home’s Value
How long do repairs hold up?
| Method | How Long It Lasts | Key Condition |
| Epoxy crack injection | 10–20 years | Only if drainage is corrected at the same time |
| Mudjacking — foam | 5–10 years | Foam outlasts slurry in Austin’s soil conditions |
| Steel pier systems | Life of structure — typically warranted | Must reach stable bearing layer below clay |
| Our take: Every one of these methods lasts longer when you fix the drainage at the same time. We tell every single customer this. It is the one thing that separates a repair that holds for 20 years from one that starts showing problems again in four. Do not skip the drainage conversation. |
What does repair do for your Austin home’s value?
- Documented, permitted repair with a transferable warranty removes the biggest negotiating chip a buyer has at inspection
- Unrepaired foundation issues can significantly reduce your Austin home’s value and kill deals during the inspection period
- For investors in East Austin, Buda, or Kyle — foundation certification from a licensed contractor is often required to close a financed sale and satisfy lender underwriting
We provide written post-repair documentation and photos for seller disclosure packets and lender review. If you are getting a home ready for the Austin market, ask us about that when you call.
