When a Foundation Needs Professional Repair
Stair-step cracks in brick, gaps at the ceiling, windows that stopped latching and floors that tilt make an inspection worth having, especially several at once or a crack that keeps widening. Only an inspection can say whether any repair is called for. North Carolina's engineering board advises in its foundation repair guidelines that when failure is suspected, a licensed professional engineer should evaluate the house before anyone decides structural repair is required.
Parts of the Durham area rest on the Triassic Basin, old sedimentary rock that the City of Durham says weathers into soil that is "very clay-rich, non-draining." Triassic basins appear on the NC Geological Survey's short list of state areas where shrink-swell clay is more common. Federal soil descriptions rate the Creedmoor soil series high for shrink-swell, while Cecil, the familiar red Piedmont clay, rates low. Clay that swells when wet and shrinks as it dries can shift a foundation unevenly.
Water sets that clay in motion. In July 2025, Tropical Storm Chantal dropped 6 to 10 inches over Durham County and its neighbors Orange, Alamance and Chatham, the National Hurricane Center reports, and the Eno River set a record crest at a gauge upstream. Leaking pipes, downspouts emptying at the wall, a yard sloping toward the house and big trees nearby can also keep one side wetter.
What This Foundation Repair Work Covers
We explain the options; the specialist chooses among them after the inspection.
- Steel, concrete and helical piers. Driven, pressed or screwed into the ground until they bear on firmer soil, these supports let a low section be raised onto them in measured steps.
- Crawl-space supports. New posts, piers or support jacks can carry a beam that has dropped or a span that sags.
- Shims and beam work. Shims close gaps between piers and beams; cracked or soft beams and joists can be doubled up or replaced.
- Slab lifting. Grout or foam pumped under settled concrete can raise it without adding deep support.
- Drainage. Downspout extensions and regrading are meant to keep clay near the walls from swinging between soaked and dry.

How Foundation Repair Is Usually Done
- Your request. You describe the symptoms on our form. We hand it to a local foundation specialist, and the specialist reaches out to arrange a visit.
- The inspection. The specialist walks the outside, reads the cracks, checks the slab or crawl space and takes floor levels. Gutters, grading and trees get checked too; for a suspected leak, ask a licensed plumber about a leak test.
- The written plan. Look for the method, the count and location of supports, drainage steps, warranty terms, and a clear answer on whether an engineer's report is included.
- The permit. In North Carolina a repair to any load-bearing part of a house needs a building permit at any price, and the foundation is load-bearing. For any Durham County address, city or rural, the Durham City-County Building & Safety Department (919-560-4144) issues it. Ask who will apply; it comes before the work.
- The work. The repair crew installs the supports and raises the house gradually, rechecking levels.
Why Homeowners Choose Foundation Repair
Foundation work is meant to protect the rest of the house. Steady supports can help doors and windows work and floors stay even. Drainage work alongside is meant to carry water away from the walls.
Before You Schedule Foundation Repair
Does it cost anything to ask?
There is no charge for sending a request. Many foundation specialists give estimates at no charge; ask about any visit fee before booking. The specialist inspects and prices the work, not us, and nothing obliges you to go ahead afterward.
Does the specialist need a state license?
That depends on size. Once a project reaches $40,000, the state's general contractor license applies, and Durham's own renovation checklist repeats that threshold. On a job that large, get the specialist's license number in writing and search for it with the NC Licensing Board for General Contractors. Below that point the license law doesn't reach the job, so your own checks carry more weight.
Will an engineer be involved?
Possibly. Put two questions out: to the specialist, whether the plan includes an engineer's report; to Building & Safety, whether the permit application needs drawings prepared by an engineer. If you'd like a second opinion, you can hire a licensed professional engineer on your own.
What should the contract spell out?
The price; the scope, with how many piers or supports, what kind and exactly where; the dates work starts and ends; how payments are scheduled; and written warranty terms, including whether they pass to a later owner. Ask who handles any plumbing or electrical piece, since North Carolina requires a licensed plumber or electrician for it.
