Fixing a Slab That Has Settled
A slab on grade rests directly on the soil, so when part of that soil shrinks, washes out or settles, the concrete follows. The edges usually show it first. They sit closest to the yard, where the ground dries fastest in a dry spell and soaks up water fastest when rain returns.
Clarksville has grown fast, from 166,722 people in the 2020 Census to an estimated 188,829 in July 2025. Plenty of newer houses stand on lots that were cut and filled during grading. Fill can settle over the years if it was not packed well, so a slab over a filled corner may drop more than the rest.
The usual fix is a row of steel or concrete piers under the low section, set down to firmer ground or rock, with the slab raised onto them in small steps.
Is Slab Foundation Repair What Your House Needs?
The specialist decides that after the inspection, not us. We can point out the signs worth listing in your request.
- Split floor tile. Tile that cracks in a line across a room can be tracing a crack in the concrete below it.
- Gaps under the baseboards. Trim that lifts away from the floor along one wall may mean that side of the slab has dropped.
- A water bill that jumps. A leak in a line under the slab can soften the soil beneath one area, so ask about a plumbing test.
- Brick that splits near a corner. Cracks that widen toward the top or bottom of an outside corner often show where an edge moved.
The Cost Side of Slab Foundation Repair
Slab jobs are priced mostly by pier count, plus any drainage or plumbing work. These are national ranges from home-cost sites, not our price, and not a quote or bid.

|---|---|---|
| Typical foundation repair, national | about $2,224 to $8,134 (average about $5,179) | This Old House (2026) |
| Piers, per pier | about $1,000 to $3,000 | This Old House (2026) |
| Structural engineer's report | about $500 to $1,000 | This Old House (2026) |
The cost calculator sizes a rough range to your house, and the foundation repair cost guide lists every row.
How Long Slab Foundation Repair Takes
Job size varies, so the specialist writes the schedule into the estimate. The steps stay about the same.
- Your request. Tell us the address and what has changed, and we set a time for a local foundation specialist to come out.
- Floor readings. The specialist runs a leveling tool across the rooms to map high and low spots, then studies the cracks inside and out.
- A plumbing question. If a leak seems possible, ask whether a plumber should pressure-test the lines under the slab before any lifting.
- Written scope. The plan should list the pier type, how many, where each goes, drainage work, who pulls any permit and the warranty.
- Piers and lift. The repair crew digs at the slab edge, sets the piers, lifts in stages, backfills and takes fresh readings.
What Delaying Slab Foundation Repair Can Cost
A slab that has moved a little is usually simpler to handle than one that has kept going for years. Early on, the talk may be a few piers and a downspout. A check sooner gives you facts to plan around, with no rush.
Dry seasons are when slab edges give themselves away. September 2026 was the 10th-driest September in 132 years for Montgomery County (NIDIS). Soils like Pembroke and Crider have clay subsoil over limestone that shrinks as it loses water. When heavy rain returns after a drought, that ground takes water back quickly, and the edges can shift again.
Common Questions About Slab Foundation Repair
How do I know my house is on a slab?
Look at the base of the outside walls. A slab home has no crawl-space door or foundation vents, and the floor sits close to the height of the yard. If you still can't tell, say so in your request and the specialist will check.
Can a leak under the slab move the foundation?
It can. Water from a broken line soaks the soil under one area, and clay over limestone can soften or wash away when it stays wet. Ask the specialist whether a plumbing test makes sense first, since raising a slab over a leak that is still running may not hold.
Will my slab be perfectly level after repair?
Don't plan on a perfectly flat floor. The aim is to bring the low area up as far as the house safely allows, and old cracks in drywall or tile may still want patching afterward. Ask the specialist to write down the planned lift and share the final readings.
Who checks the contractor's license?
You do. Once a job reaches $25,000, Tennessee wants the contractor to hold a state license for it. Get the license number and classification from the specialist, then look them up on the state's license verification site. For homes inside Clarksville city limits, ask about the City's contractor registration too.
