Shimming, Re-Leveling and Replacing Piers
Under a raised floor, wood joists sit on beams, and the beams sit on posts or piers set into the ground. A sill plate runs along the top of the foundation wall, and thin shims fill the space between each pier and its beam. When shims crush, a post settles or damp wood softens, the floor above starts to dip.
The specialist may tap in new shims to re-level a beam, add posts where a beam spans too far, or replace a settled pier. Weak joists can be sistered, with a new board fastened alongside the old one.
Crawl spaces are common under the older houses around downtown and Austin Peay. Downtown also has an H-1 historic district, so if a repair changes the outside, such as new vents, check with the Regional Planning Commission first; exterior changes there may go through design review.
Is Crawl Space Repair What Your House Needs?
A trip under the house by the local foundation specialist settles that question. We can tell you which signs belong in your request.
- Floors that sag or bounce. A soft dip in the middle of a room, or a floor that shakes when someone walks past, can mean a post has dropped.
- A damp crawl space. Standing water, wet soil or a musty smell from below keeps moisture close to the wood and the ground under the piers.
- Soft sill plates or joists. Wood that crumbles when you press a screwdriver into it has usually stayed wet for a long time.
- Leaning or cracked posts. Piers that tilt, crack or pull away from the beam no longer carry their share of the floor.
The Cost Side of Crawl Space Repair
A crawl-space job can be a handful of shims or new piers plus joist work, so these national ranges from home-cost sites are wide. None is our price, a quote or a bid.

Our cost calculator counts piers, so treat its answer as rough for a raised home where shims or new posts may do the job. The foundation repair cost guide lists every row.
How Long Crawl Space Repair Takes
It depends on how much wood comes out and how easy the space is to reach; the schedule comes with the estimate.
- Request a visit. Tell us about the floors and anything you have seen below, and we book a local foundation specialist.
- Under the house. The specialist checks each post, pier, shim, beam and joist, notes moisture, and measures how far the floor is out of level.
- The written scope. It should name which piers get reset or added, which boards get sistered or replaced, moisture or drainage steps, who pulls any permit and the warranty.
- The work and a recheck. The repair crew jacks the beams a little at a time, sets new supports, swaps damaged wood and measures the floors again.
What Delaying Crawl Space Repair Can Cost
Wood under a house seldom improves while it stays damp, and one soft patch is a smaller repair than a whole rotted wall. An early check gives you a shorter list, and the timing stays your choice.
Local ground plays a part. Soils like Baxter and Crider have clay subsoil over limestone, and Dickson soils carry a dense fragipan 18 to 36 inches down, and water can collect on top of it (NRCS). With about 50 inches of rain in a typical year (Visit Clarksville), a poorly drained crawl space can stay wet for long stretches.
Common Questions About Crawl Space Repair
How can I tell if my house has a crawl space?
Walk around the outside. A small access door or a row of vents near the ground usually means there is a crawl space. The floors sit a step or more above the yard and can sound a little hollow. Slab homes sit lower, with no way to get under the floor.
Are new shims enough to fix a sagging floor?
Sometimes. If the posts and beams are sound, re-shimming may bring the floor back close to level. A settled pier or a rotted beam calls for more work. Ask the specialist to explain in writing why the plan picks shims, new posts or new piers for your house.
Does a damp crawl space matter for the foundation?
It can. Wet soil can let posts settle, and wet wood softens over time. A specialist may suggest gutter or downspout changes, regrading, better vents or a ground cover. Moisture steps like these often help a structural repair hold up for longer.
What should I ask before signing?
Ask what licenses and City registration the specialist holds. A Tennessee contractor's license comes into play at $25,000, and you can check it on the state's license verification site. Also ask for an insurance certificate, a scope that names each support and board being replaced, and warranty terms that say whether they pass to a buyer.
