Signs your foundation is actually moving
- Doors and windows that used to work and now stick, drag, or won't latch.
- Diagonal cracks running from the corner of a door or window frame, especially wider than a credit card.
- Gaps opening between the wall and the baseboard, or between crown moulding and ceiling.
- Floors that feel sloped, or a ball that rolls the same direction in more than one room.
- Brick or mortar cracks outside that step diagonally up the wall.
- A gap opening between the slab edge and the soil, or soil pulling visibly away from the house in dry months.
How the repair itself works
- Piers are driven or drilled down until they reach soil or rock that doesn't move seasonally, then the structure is supported on them.
- Pressed concrete pilings are the most common residential method in Central Texas. Steel piers go deeper and are used where loads or depths demand it.
- Drilled bell-bottom piers are poured in place and are common under pier and beam construction and additions.
- Lift is a judgement call, not a setting. Recovering every millimetre can crack finishes, plumbing, and brick. A good contractor will tell you where they intend to stop, and why.
- Plumbing under a slab should be tested before and after significant lift. Movement breaks pipes, and a leak you don't find becomes the cause of the next problem.
Know which slab you have before anyone drills
- Post-tension slabs contain steel cables under tension and are extremely common in Central Texas homes built from the 1980s onward.
- Cutting or coring a post-tension slab without locating the cables is dangerous and can cause serious structural damage. Any competent contractor will scan first.
- Conventional slabs are steel-reinforced with rebar and are more forgiving to core, which matters for plumbing access.
- Look for a stamp in the garage slab or a note in your builder documents. If nobody can tell you which you have, that is itself a reason to slow down.
What slab repair involves
- Piers are placed around the perimeter, and sometimes through the interior, at spacings the engineering scope specifies.
- Interior piers usually mean opening the floor covering, which changes the cost and the disruption considerably. It should be in the bid, not a surprise.
- Lift is done gradually and monitored. The goal is stabilising the structure, not chasing a perfectly level floor.
- Expect some cosmetic cracking as the structure comes back. Ask specifically what cosmetic repair is and is not included.
- A hydrostatic plumbing test before and after is strongly worth having on any significant slab lift.
What about price?
We don't publish prices, and we won't. Round Rock Foundation Repair Pros is a referral service — we don't perform foundation work and we haven't seen your house, your soil, or how far it has moved. Any range we printed would mislead you and unfairly anchor the contractor quoting the job.

What we can do is show you exactly what a contractor is pricing, so you can read a bid
properly.
Why we won't quote you a number
Two houses on the same street can price completely differently. One sits on clay that moves, the other on shallow limestone. One needs eight perimeter piers, the other needs interior work that means pulling up flooring. That is why we won't publish a number - only a contractor who measures your house can tell you what your job costs.
What a contractor is actually pricing
| Factor | Why it moves the number |
|---|---|
| Pier count | The single biggest driver. It comes from where the movement actually is, which is why an elevation survey should precede any number. |
| Depth to stable ground | Piers go down until they reach soil or rock that doesn't move seasonally. West of I-35 that can be shallow limestone; east on the Blackland clay it can be considerably deeper. Depth is not knowable to the inch until they dig. |
| Pier type | Pressed concrete pilings are the common residential method here. Steel piers go deeper and carry more load. Drilled bell-bottom piers are poured in place. They are not interchangeable and they don't price alike. |
| Interior versus perimeter | Perimeter-only work stays outside. Interior piers mean opening the floor, working inside the house, and putting the finishes back. It is a materially different job. |
| How much lift | Stabilising costs less than attempting maximum recovery, and often risks less damage to finishes and plumbing. Where the contractor intends to stop belongs in the bid. |
| Access | Can equipment get around the house? Tight side yards, mature landscaping, pools, patios and fences all add hand-work and time. |
| Plumbing testing and repair | A hydrostatic test before and after is strongly worth having. If a line under the slab is already broken, repairing it is separate scope - and finding it after the crew leaves is far worse. |
| What gets restored afterward | Cosmetic repair, landscaping and flatwork reinstatement vary enormously between bids and are a common reason two quotes look far apart. |
How to compare bids fairly
- Put every bidder on identical scope in writing - pier count, pier locations, pier type, depth criteria, and how much lift is being attempted.
- If you have an engineer's report, hand the same report to every contractor. That is the single most effective thing you can do to make bids comparable.
- Check whether interior piers are included. A bid without them will always look cheaper than one with them, and they are not the same job.
- Confirm whether a pre- and post-repair hydrostatic plumbing test is included. Slab movement and plumbing leaks cause one another, and finding out afterwards is the expensive order to discover it in.
- Ask what cosmetic repair is included - drywall, paint, brick, tile - and what is explicitly excluded.
- Compare warranties line by line: length, transferability to a future buyer, what voids it, and who honors it if the company changes hands.
Questions to ask every contractor
- Texas does not license this trade, so: are you registered as a contractor with the city, and can I verify that myself?
- Can your insurer send me certificates for general liability and workers' compensation directly?
- How long have you personally been doing this work in Williamson County, and under this company name?
- What did you measure to reach this diagnosis, and can I see the elevation readings?
- How much lift are you attempting, and where will you stop?
- What happens if you hit rock shallower or deeper than expected - how does that change the price, and who decides?
- Who does the work - your own crews or a subcontractor?
- Can I see the full warranty document before I sign, not after?

Foundation Repair — Questions Round Rock Homeowners Ask
How much does foundation repair cost in Round Rock?
We're a referral service and we don't quote foundation work, so we won't invent a number. What we can tell you is what it turns on: how many piers the scope calls for, how deep they have to go to reach stable ground, whether they're pressed concrete or steel, how much lift is being attempted, access around the house, and what has to be repaired afterward. Get two written bids on identical scope.
Do I need a structural engineer, or just a contractor?
For anything significant, hire a licensed professional engineer first. They inspect, diagnose, and write a repair scope - and they have nothing to sell you. Contractors then bid that same scope, which is the only way to compare bids fairly. For a single hairline crack with no other symptoms, a contractor assessment is usually enough.
Are foundation repair contractors licensed in Texas?
No. Texas has no state license for foundation repair, which surprises almost everyone. There is no license number to look up. Verify city contractor registration, general liability insurance and workers' compensation instead, ask how long they have worked in Williamson County, and insist on a written scope.
Is my foundation problem urgent?
Usually not. Foundation movement is slow damage measured in seasons, and a company telling you on a first phone call that it's an emergency deserves a second opinion. The real exception is water: an active leak under the slab, or water pooling against the house, should be dealt with immediately because it drives the movement.
Will repair damage my plumbing?
It can. Lifting a slab moves everything cast into and under it, including drain lines that are already decades old. Ask whether a pre- and post-repair plumbing hydrostatic test is included, and get the answer in writing. Finding a broken line after the crew has gone is a far worse conversation.
How do I know if I have a post-tension slab?
Many Central Texas homes built from the 1980s on are post-tension. Check for a stamped notice in the garage or on the slab edge, or your original builder paperwork. It matters enormously: cutting a post-tension slab without scanning for cables first is genuinely dangerous.
Can a slab be repaired without going inside the house?
Sometimes. Perimeter piers alone are enough for many houses. Interior piers require opening flooring and are more disruptive and more expensive. Which one you need is determined by where the movement actually is, which is what an elevation survey measures.
What does slab repair cost in Round Rock?
We don't publish prices - we're a referral service and haven't seen your house. Slab repair turns on pier count, depth to stable ground, pier type, whether interior work is needed, and access. Bids on identical scope are comparable; bids on different scope are not.
Will the cracks in my walls close up?
Some will close as the structure comes back, some won't fully, and new hairline cracking during lift is normal. Cosmetic repair is a separate scope item. Ask whether drywall, paint, brick or tile repair is included before you sign.
How long does slab repair take?
A straightforward perimeter job is often a few days. Interior piers, heavy access constraints, or a large pier count extend that. Weather matters too - this work involves excavation, and Central Texas clay is miserable to dig wet.
Why are two Round Rock foundation quotes so different?
Nine times out of ten they are not quoting the same job. Different pier counts, different depths, one includes interior piers and one doesn't, one includes plumbing testing and cosmetic repair and the other excludes both. Put both on identical written scope and the gap usually shrinks dramatically.
Is the cheapest foundation bid ever the right one?
Sometimes, if it is genuinely the same scope. Far more often it is cheaper because it is less work - fewer piers, no interior, no plumbing test, no restoration. Read what is excluded before you read the number.
Should I pay for an engineer before getting bids?
On any significant repair, yes. An independent engineer's report costs a fraction of the repair, gives you a scope every contractor can bid identically, and comes from someone with nothing to sell you.
Does homeowners insurance pay for this?
Usually not. Texas policies typically exclude earth movement and settling. Damage traced to a sudden covered event such as a plumbing leak is sometimes handled differently. Read the policy and speak to your agent rather than assuming.
Can I do part of it now and part later?
Sometimes, and a good contractor will tell you honestly whether phasing is structurally sensible or just deferring. Drainage correction first is frequently the smartest sequence in this soil.
