Foundation repair is one of those things nobody budgets for. You notice a crack, a sticking door, or a gap along a window — and suddenly you're wondering if you're looking at a $500 fix or a $15,000 problem.
The good news: most foundation repairs in Williamson County fall between $3,000 and $15,000. And once it's done right, it's done for good. Here's what drives those numbers so you know what to expect when contractors show up.
Foundation Repair Cost Breakdown
Here's what each type of repair typically costs in Williamson County as of 2026:
| Repair Type | Cost Range | What's Included |
|---|---|---|
| Pressed Steel Piers | $300 – $700 per pier | Steel piers driven to bedrock or stable soil. Most permanent solution. Lifetime transferable warranty is standard. |
| Drilled Concrete Piers | $400 – $800 per pier | Concrete piers poured into drilled holes. Good for heavy loads. Takes longer to install than steel. |
| Total Pier Installation (8–20 piers) | $4,000 – $14,000 | Full pier job for a typical Williamson County home. Most homes need 8 to 20 piers depending on size and damage. |
| Slab Leveling | $3,000 – $8,000 | Lifting and leveling a settled concrete slab foundation. Often combined with pier installation. |
| Drainage Correction | $1,500 – $5,000 | French drains, surface grading, gutter extensions. Addresses the root cause of many foundation problems in clay soil. |
| Crack Repair (Epoxy/Polyurethane) | $250 – $800 per crack | Injecting epoxy or polyurethane into foundation cracks. Cosmetic and structural depending on crack type. |
| Mudjacking / Foam Lifting | $500 – $2,500 | Pumping material under the slab to raise it. Less expensive but not as permanent as piers. Good for minor settling. |
What Affects Your Foundation Repair Cost
Two houses on the same street can get very different quotes. Here's why:
Number of Piers Needed
This is the biggest factor. A small home with settling on one side might need 6 to 8 piers. A larger home with settling on multiple sides could need 15 to 20. Each pier adds $300 to $700 to your total. A contractor should explain exactly where each pier goes and why.
Severity of the Damage
A foundation that's settled half an inch is a different job than one that's dropped two inches. More severe settling often means deeper piers, more material, and more labor. Catch it early and you'll spend less.
Accessibility
Can the crew easily get to all sides of your home? Tight fences, decks, porches, and landscaping can make the job harder. Homes with additions or sunrooms sometimes need interior pier work, which costs more because it involves cutting through the slab inside the house.
Soil Conditions
Williamson County has a wide range of soil. Homes in Hutto and Taylor sit on heavy Blackland Prairie clay that moves a lot. Homes in western Cedar Park or parts of Liberty Hill may sit partially on limestone. The soil type affects what kind of piers work best and how deep they need to go.
Home Size and Foundation Type
Bigger homes have more foundation to support. A 1,500-square-foot starter home costs less to repair than a 3,500-square-foot home. Pier-and-beam foundations (common in older Georgetown and Taylor homes) are typically less expensive to repair than slab-on-grade foundations.
Drainage Issues
If poor drainage caused your foundation problem, the repair company may recommend fixing the drainage too. This adds $1,500 to $5,000 but prevents the same problem from coming back. In Williamson County's clay soil, drainage correction is often worth the extra cost.
Foundation Repair Costs by City
Costs vary slightly across Williamson County based on local soil conditions, average home size, and contractor availability:
| City | Typical Range | Notes |
|---|---|---|
| Georgetown | $4,000 – $12,000 | Sun City homes often need 10+ piers. Older downtown homes may need pier-and-beam work. |
| Round Rock | $3,500 – $10,000 | Wide range due to limestone in west vs clay in east. Older homes near downtown settle more. |
| Cedar Park | $3,500 – $9,000 | 2000s-era homes showing early settling. Limestone substrate helps in western areas. |
| Leander | $4,000 – $11,000 | Fast-built homes on clay soil in newer subdivisions. Crystal Falls, Travisso common areas. |
| Liberty Hill | $4,500 – $13,000 | Larger lots and homes drive costs up. Limestone/clay mix creates uneven settling. |
| Hutto | $3,500 – $10,000 | Heavy Blackland clay east of I-35. 5-15 year old homes starting to show settlement. |
| Pflugerville | $3,500 – $10,000 | Wide range of home ages. Older west-side homes may need more work. |
| Taylor | $3,000 – $9,000 | Most affordable area. Older pier-and-beam homes cost less to repair. Heavy Taylor Clay soil. |
How to Compare Foundation Repair Quotes
Getting quotes can be confusing. Different companies may recommend different things. Here's how to make sense of it:
Get at Least Three Quotes
This is non-negotiable. Three quotes give you a baseline for what's reasonable. If one quote is dramatically lower or higher than the others, ask why. The cheapest option isn't always the best. Neither is the most expensive.
Ask About the Warranty
For pier installations, you should expect a lifetime transferable warranty. That means it covers the repair for as long as you own the home — and it transfers to the next owner when you sell. Be cautious of companies offering limited warranties (like 10 or 25 years) on piers. Ask if there are annual inspection fees required to keep the warranty active.
Ask About Engineering Reports
Some companies include a post-repair engineering report. Others charge extra. An engineering report from a licensed structural engineer documents the work that was done and confirms the foundation is stable. This is valuable when you sell the home. Independent pre-repair reports cost $300 to $500 and are worth every penny for repairs over $5,000.
Understand What's Included
Does the quote include cleanup? Landscaping repair? Moving and replacing any concrete walkways or driveways that are in the way? Some companies include these; others charge extra. Ask so you're comparing apples to apples.
Check for Financing
Many foundation repair companies in Williamson County offer financing. Common options include 0% interest for 12 to 18 months, or longer-term plans with low interest. If you need financing, ask about it upfront so you can factor the monthly payment into your decision.
Don't Wait — Early Repair Saves Money
Here's something foundation repair companies will tell you that's actually true: catching a problem early really does save money. A foundation that's settled slightly might need 6 piers at $400 each — that's $2,400. Wait a few years and that same foundation might need 14 piers plus drainage work — now you're at $8,000 or more.
In Williamson County, where our clay soil never stops moving, small problems tend to get bigger. If you're seeing signs of foundation trouble, get a free inspection sooner rather than later. The inspection costs you nothing, and knowing is better than worrying.
