Typical Costs by Repair Type
Six of these rows are national ranges taken from home-cost websites. The Clarksville row is the odd one out: it is a single cost site's local average from 2024, and it sits lower than the national figures. Read every row as a planning range. We don't set any of these prices, and no row is a quote or bid. We found no Tennessee per-pier number, so the pier row is national as well.

Check the units before you compare rows. Piers and cracks are priced one at a time. The crawl space and pier and beam rows describe a whole job, and the engineer's report pays for a written review, not for any repair. Leveling is priced its own way: HomeGuide (2026) lists shims at about $1,000 to $3,500 and underpinning for extensive damage at about $10,000 to $20,000.
The Biggest Cost Variables
Much of the ground around Clarksville is clay subsoil over limestone. That clay soaks up water, then dries and shrinks, and 2026 has been a dry year. NIDIS ranked January through September as the seventh-driest such stretch in 132 years for Montgomery County. With the median owner home valued at $263,600 (Census QuickFacts), a repair bill is worth planning for. These items move the total most.
- The pier count. Each pier carries its own price, so a short run along one wall costs far less than a ring around the whole house. The specialist sets the count after measuring.
- Crawl space access. A low or cramped crawl space slows every step. If your home sits over a crawl space, as many older homes near downtown and Austin Peay do, the plan may add posts, shims or joist repairs.
- Plumbing repairs. A leak under a slab or in a crawl space adds water to the soil. If a plumbing test turns one up, the plumber bills that fix apart from the foundation work.
- Drainage work. Turning downspouts away from the walls or regrading a yard that slopes toward the house can be part of the plan, and it adds a line of its own.
- Any permit. Ask whether the price covers pulling a permit and booking inspections with the City or County Building and Codes office.
- An engineer's report. A written evaluation adds about $500 to $1,000 nationally (This Old House, 2026).
- Sinkhole work. Sinkholes are a common feature of Montgomery County. Fixing one falls under County rules that require a report from a Tennessee-licensed geotechnical professional or engineer, so it is planned and priced as a separate project.
What a Good Foundation Estimate Includes
A written estimate is only useful if you can hold it next to another one. Look for these items in each estimate the specialist hands you, and ask about anything that is missing.
- A support plan. How many piers or supports, what type, and where each one goes, marked on a sketch of the house.
- Floor measurements. The elevations taken at the visit, and whether a second set will be taken after the work.
- What is left out. Plumbing, drainage, flooring and landscaping, each marked as included or not.
- Permit duty. Who pulls any permit and who books the inspections.
- Papers to check. A current certificate of liability insurance and, on a job of $25,000 or more, the state license number and classification.
- Warranty terms in writing. What the warranty covers, how long it lasts, and whether a later owner can take it over.
Tennessee asks for a state contractor's license on jobs of $25,000 or more, and the City of Clarksville runs its own contractor registration. Look up any license number on the state's license verification site. The state's consumer guidance also says a home improvement contractor generally may not ask for over one-third of the total as a deposit. Our Tennessee foundation repair rules page explains each point. This is general information, not legal advice.
What a Structural Engineer Checks
A structural engineer you hire on your own answers only to you. The engineer looks at how the house has moved, studies the floor levels, cracks and framing, and puts the likely cause and a fix in writing. The report is worth paying for if two estimates disagree sharply on pier count, if the house is about to change hands, or if you want a sealed plan.
Some foundation specialists bring in a licensed professional engineer as a routine step, and some don't. Ask if an engineer will look at your house or put a seal on the plan, and whose bill that is. We found no City or County page calling for an engineer's letter on routine foundation work, so ask the Building and Codes office for your address.
Find Out What Your Repair Costs
The calculator turns your footprint and the part of the house that shows movement into a rough range. It assumes about one pier every 8 feet along the walls that moved. The 8-foot gap is a planning assumption we chose, not a rule. Your real pier count comes from the specialist's visit. Crawl space homes often need shims, new posts or beam work instead, so their range is looser.
For a figure tied to your own house, send a request through the form. Sending it costs nothing. We book the visit. Then a local foundation specialist working in Montgomery County walks the house, measures it and puts the estimate in writing. Many specialists don't charge for that visit, but ask before it is booked. Whether to hire anyone stays your call.
