Cost Ranges for Foundation Repair
Each figure below comes from a national home-cost website, with its source and year beside it. None of them is our price, and none is a quote for your house. Local numbers spread even wider: a 2024 estimate for Columbia, SC ranged from about $2,300 to $23,800, depending on how severe the problem was (HomeBlue, 2024). No neutral South Carolina per-pier figure was found, so the pier rows are national.
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical foundation repair, national | about $2,225 to $8,133 (average about $5,174) | Angi (2026) |
| Steel piers, per pier | about $1,000 to $1,600 | HomeGuide (2026) |
| Piers or underpinning, per pier | about $1,000 to $3,000 | Angi (2026) |
| Crawl space repair | about $2,500 to $8,000 on average; $15,000 or more for multi-step jobs | HomeGuide (2026) |
| Pier and beam repair | about $750 to $25,000 | Angi (2026) |
| Crack repair, per crack | about $250 to $800 | HomeGuide (2026) |
| Structural engineer's report | about $500 to $3,000 | HomeGuide (2026) |
Check the unit on each row before you add anything up. Pier figures are for one pier, and a single job can use four or a few dozen. The crawl space and pier and beam rows cover a whole job. Smaller crawl-space fixes are priced on their own: HomeGuide (2026) puts sistering one floor joist at about $150 to $325, and shim leveling at about $1,000 to $3,500 for the house.
Pier Count, Depth and Access
Ground changes fast around the Midlands. Red Piedmont clay lies to the north and west, and loose Sandhills sand lies to the south and east, so piers may stop at very different depths on two nearby lots. With a median owner home value of $264,300 in Columbia, SC (Census QuickFacts), a repair is a large expense, and these are the things that move it.
- How many piers. Every pier adds labor and steel, so the count shapes the total more than anything else on the list.
- Depth to firm soil. Piers driven through deep sand or uneven weathered rock take longer and use more material than short ones.
- Access around the house. Decks, porches, tight side yards and interior piers all slow the crew and raise the labor line.
- Crawl-space height. A low crawl space means slow, cramped work under the floor, which shows up in the price of joist and post repairs.
- Plumbing repairs. A leak found under a slab or in a crawl space is fixed by a plumber, and that bill sits apart from the foundation work.
- Drainage work. Downspout extensions, grading or a drain line may be added so the soil stays drier after the repair.
- Permits. Structural work inside City of Columbia limits needs a permit; ask whether the price covers pulling it and the inspections.
- An engineer's report. A written evaluation or repair design adds about $500 to $3,000 nationally (HomeGuide, 2026).
Spotting Gaps in a Foundation Quote
A quote you can compare line by line is worth more than a single total. When the specialist hands you one, look for each item below. If something is missing, ask before you sign.
- Written scope. The number and type of piers or supports, with a drawing that marks where each one goes.
- Floor readings. Elevation measurements taken before the work, plus a plan for checking them again after.
- Permit owner. Which party pulls the permit with the City, Richland County or Lexington County, and who books the inspections.
- Insurance certificate. A current certificate of liability insurance in the company's own name.
- Warranty terms. What the written warranty covers, how long it lasts and whether it moves to the next owner if you sell.
- Cleanup. Who repairs floors, patches concrete and replaces shrubs or sprinkler lines moved during the job.
There is no South Carolina license made just for foundation repair. Builders of homes must hold a license, and many specialty trades must register, with the SC LLR Residential Builders Commission, so get the number and search it on verify.llronline.com. For homes inside city limits, ask to see the company's current City of Columbia business license too. If insurance is involved, the deductible is yours to pay. State law lets buyers cancel certain financed sales signed at home; ask the company whether yours qualifies. Our South Carolina foundation repair rules page covers each point in more depth.
Why an Engineer's Report Can Help
An engineer you hire yourself answers to you, not to the business selling the piers. That second opinion is useful when two quotes disagree, when you are buying or selling, or when the house is old, large or built in an unusual way. In South Carolina, engineers are licensed through a state board within SC LLR, and you can look one up on verify.llronline.com.
Some foundation companies bring an engineer into every job, and some never do. Ask the specialist whether a licensed professional engineer will design or review the repair. Then ask the permit office whether your repair needs an engineer's plan or letter. For the City, that office is Planning & Development Services at 1401 Main Street. Nationally, a structural engineer's report runs about $500 to $3,000 (HomeGuide, 2026).
Move From Ranges to a Quote
The calculator above estimates a pier count from your footprint and the share of the house that has moved. It assumes about one pier every 8 feet along the affected walls. That spacing is our planning assumption, not a rule, and the specialist sets the real count. Crawl-space homes often need shims, posts or sistered joists instead, so their range is looser.
For a real number, request an estimate through the form. There is no cost to send it. We arrange a visit from a local foundation specialist who works across Richland and Lexington Counties; the specialist checks the house, writes the quote and leaves the choice with you. Many foundation specialists give estimates at no charge, but ask before the visit.
