How the referral works
How our contractor-matching service works
Tennessee Foundation Repair is an independent referral service. We don't inspect, diagnose, or repair foundations, and we don't employ crews or engineers. We connect you with participating independent foundation repair contractors who do the work.
You call the number on this site
Have the property address or ZIP code ready, plus what you are seeing: cracks, sloping floors, sticking doors, a bowing wall, and how long it has been going on.
Your call is routed to a participating contractor
Your call is connected with a participating independent foundation repair contractor who serves your area, if one is available. We do not inspect or send anyone ourselves.
You deal with that contractor directly
The contractor evaluates the house, recommends a repair, quotes the price, and does any work you agree to under their own business name, license, insurance, and warranty. You decide whether to hire them; there is no obligation.
Good to know: availability and eligible services depend on which participating contractors cover your ZIP code. Whoever you hire, ask for their Tennessee license number (if the job needs one) and check it with the state's license verification search. Our hiring questions cover the rest.
Common warning signs of foundation problems
These are the signs that send most Tennessee homeowners looking. They are symptoms, not a diagnosis: some have harmless causes, and finding out which takes an on-site look.
Main foundation repair services
Signs, causes, repair methods, typical costs, and what to ask a contractor.
Foundation Settlement Repair and Stabilization
When part of a house sinks lower than the rest, the job is to stop the movement first and level what can be leveled second. Here is how settlement repair and foundation stabilization work, and what is different about Tennessee ground.
- Settling and sinking foundations
- Stabilization with piers
Foundation Crack Repair
A crack in the basement or crawl space wall is the most common reason people start looking into foundation repair. Here is how to tell what kind you have, what the repair options are, and when a crack is a sign of something bigger.
- Poured, block, and brick walls
- Injection and reinforcement
Crawl Space Structural Repair
Many Tennessee houses sit on crawl spaces, and the structure down there carries every floor above it. Here is what goes wrong with crawl space supports, how it gets repaired, and how that differs from encapsulation.
- Sagging and bouncy floors
- Posts, beams, joists, and sills
What causes foundation settlement and movement in Tennessee
Foundations move when the soil under or beside them changes. In Tennessee, that usually comes down to rock, clay, fill, and water. Read the full guide.
Karst and sinkholes
About 43.5% of Tennessee sits on karst or rock that can form it: limestone and dolomite that dissolve into voids (USGS).
Thin soil vs. deep soil
Median depth to bedrock is about 8 ft in the inner Central Basin and about 42 ft in the East Tennessee Valley and Ridge (USGS).
Fill and clay
Poorly compacted fill settles; clay shrinks in dry spells and swells when wet.
Water
Most of the state averages 44 to 56 inches of rain a year (NOAA). Runoff at the foundation softens and erodes soil.

What to expect
Common foundation repair methods
The right repair depends on the cause, the foundation type, and the soil. These are the methods most Tennessee proposals draw from.
Foundation piers and underpinning
Steel push piers or helical piers carry a settling section down to firmer soil or rock. Foundation piers
Settlement repair and stabilization
Stopping movement and, where possible, lifting back toward level. Settlement repair
Wall anchors, braces, and carbon fiber
Holding a bowing or leaning basement wall. Bowing wall repair
Crack injection and masonry repair
Epoxy or polyurethane for poured walls; repointing or rebuilding for block and brick. Crack repair
Crawl space supports
New posts, beams, and joist repair under sagging floors. Crawl space repair
Drainage corrections
Gutters, extensions, grading, and drains: often part of the fix, sometimes the whole fix for minor problems.
Straight answers
What you can do vs. when to get a professional evaluation
Watching, measuring, and fixing drainage are things a homeowner can do. Diagnosing the cause and repairing structure are not.
| What you are seeing | What you can do now | When to get a professional evaluation |
|---|---|---|
| A thin vertical crack in a poured concrete wall | Photograph it with a ruler or coin for scale and date the photo; check it again after a few months and after heavy rain | It widens, one side sits higher than the other, or water comes through |
| Stair-step cracks in block or brick | Photograph and date them; note any doors or windows nearby that stick | The cracks are getting longer or wider, or bricks or blocks have shifted out of line |
| A basement wall leaning or bowing inward | Keep the area clear and dry; do not try to push or brace it yourself | Always: horizontal cracks and inward bowing are a structural question |
| Sloping or bouncy floors over a crawl space | Look (safely) for standing water or wet wood; note where the floor dips | Floors are getting worse, posts or beams look damaged, or wood is soft or rotted |
| Doors and windows suddenly sticking | Note which ones and when; seasonal humidity can do this too | Several stick at once, with new cracks above the frames |
| A depression or hole opening near the house | Keep people and pets away; on public land or a road, report it to local officials | Always, and call 911 if a building is moving or there is any immediate danger (TEMA) |
General guidance, not a diagnosis. Safety steps follow the Tennessee Emergency Management Agency'sgeological hazards guidance. Never jack, cut, or remove a structural support yourself.

- How many piers or supports: priced per unit.
- Depth to firm ground: varies from a few feet to dozens across Tennessee.
- Access: finished basements, tight crawl spaces, decks, and landscaping.
- Engineering, permits, and drainage work, often separate line items.

Frequently asked homeowner questions
Is Tennessee Foundation Repair a foundation repair company?
No. Tennessee Foundation Repair is an independent contractor-referral service. When you call, you are connected with a participating independent foundation repair contractor who serves your area, if one is available. That contractor evaluates the house, quotes, and performs any repair under their own business name, license, insurance, and warranty.
How much does foundation repair cost in Tennessee?
HomeAdvisor's June 2026 national data puts the average foundation repair at $5,174, with most projects between $2,225 and $8,133. Crack repair runs $250 to $800, piers $1,000 to $3,000 each, bowing walls $4,000 to $12,000, and a settling or sinking foundation $5,000 to $25,000.
Does a foundation repair contractor need a license in Tennessee?
Jobs of $25,000 or more need a state contractor license. In Bradley, Davidson, Hamilton, Haywood, Knox, Marion, Robertson, Rutherford, and Shelby counties, residential jobs from $3,000 to $24,999 also need a state Home Improvement license. Check any license at verify.tn.gov.
Are foundation cracks always serious?
No. Thin vertical cracks in poured concrete are often shrinkage. Horizontal cracks, stair-step cracks in block, cracks wider at one end, and cracks that keep growing are more likely to signal movement and deserve a professional evaluation.
Does homeowners insurance cover sinkholes in Tennessee?
Only if you have sinkhole coverage. Tennessee law requires insurers to offer it, but it is optional and usually costs extra, and standard policies often exclude settling and earth movement. Ask your agent what your policy includes.
Do you offer free inspections?
We don't inspect anything ourselves. Whether a contractor's evaluation is free or paid is up to that contractor, so ask when you're connected. For an assessment with nothing to sell, an independent structural engineer typically charges $340 to $780, per HomeAdvisor.
