Foundation FAQ
These answers are general information, not legal advice and not a diagnosis of any home.
How does a request work?
You fill in the estimate form, and we hand it to one local foundation specialist. That specialist contacts you to arrange any visit, then does the inspection and any written estimate. There is no cost to send a request. Many foundation specialists also charge nothing for an estimate, but ask before the visit so there are no surprises.
Does North Carolina license foundation repair contractors?
Not as a separate trade. The state licenses general contractors, and that license applies to projects of $40,000 or more. Durham's own renovation checklist repeats the line, with a notarized Owner Exemption Affidavit as the owner's alternative. On a job that size, the specialist should give you a license number, which you can verify with the NC Licensing Board for General Contractors. For work under $40,000, that license law doesn't reach the job, so the contract, references and permit matter even more.
Does foundation work need a permit in Durham?
Yes. North Carolina exempts many smaller home projects from permits, but repairs to load-bearing parts of a house are not among them, whatever the cost. The Durham City-County Building & Safety Department (919-560-4144) issues permits for the City and unincorporated Durham County, and its Small Project Review handles repairs to existing single-family homes. Ask the specialist who will apply.
Will I need a structural engineer?
That depends on the house and the plan. The state's engineering board, in its published foundation repair guidelines, advises sending any suspected foundation failure to a licensed professional engineer to evaluate. So ask the specialist whether an engineer's report is part of the plan, and ask Building & Safety whether your permit needs drawings from an engineer. You can also hire an engineer yourself.
What should a written contract include?
The total price; a scope that names each pier or support by count, type and placement; start and finish dates; and when each payment is due. Changes to price or work should go on signed change orders. Ask for the warranty terms in writing too, including whether they carry over to the next owner if you sell.
Can I cancel after I sign?
North Carolina's three-day right is narrow. It covers a job bought on credit that the seller sold to you in person at your home. Then a written cancellation works up to midnight on the third business day after signing. A notice sent by mail counts from the day you mail it, and any written form will do. Other contracts may give no such right, so read the cancel terms first.
Who handles plumbing or electrical pieces of a job?
In North Carolina, that work needs a licensed plumber or electrician. We do no plumbing or electrical work and offer none, so ask the specialist who will handle any sump, drain or wiring piece. If you suspect a leak under a slab or in a crawl space, a licensed plumber can tell you whether a leak test makes sense.
Why do foundations move around Durham?
Parts of the Durham area sit in the Triassic Basin, and the NC Geological Survey names those basins as areas where shrink-swell clay turns up more often. The Creedmoor soil series, for one, is rated high. Such clay can swell when wet and shrink when dry, and some soils here can stay wet near the surface in spring. Gutters, grading and trees close to the walls matter too.
What does foundation repair cost?
National figures from This Old House (2026): most repairs run about $2,224 to $8,134, piers about $1,000 to $3,000 each and an engineer's report about $500 to $1,000. We use no Durham figure, and none is our price; they are planning ranges, not a quote or bid. Whether your homeowner's policy pays for anything is a question for your own insurer. See the cost guide.
