Most foundation problems start small. A door that suddenly won't latch, a hairline crack you didn't notice last year, a floor that feels just a little off when you walk across it. These are the kinds of things homeowners brush off until they get serious. By the time it's obvious something's wrong, the fix is usually expensive.
We pour new foundations and footings for additions, detached structures, and new construction across the Lake Norman area, but we don't do foundation repair work on existing homes. That said, we walk a lot of properties and see foundation issues constantly. Here are the warning signs worth paying attention to.
What to watch for
Doors and windows that suddenly stick or won't close right are often the first sign of foundation movement. Wood frames flex with the structure, so when the foundation shifts even a little, the openings change shape just enough to bind the door. If you've got multiple doors acting up at the same time, that's worth investigating.
Cracks in interior walls, especially diagonal cracks running from the corners of doorways or windows, are a step up in severity. Hairline cracks in drywall are normal and usually cosmetic. But cracks that run diagonally from corners, cracks wider than a quarter inch, or cracks that keep coming back after you patch them indicate the structure is moving.
Gaps between walls and ceilings, or between walls and floors, mean the framing has separated from where it used to sit. Same with crown molding pulling away from the ceiling. These can develop slowly enough that you don't notice until you look closely.
Floors that feel uneven or slope noticeably toward one side of the house point to settling under part of the foundation. NC red clay swells and shrinks with moisture, so some seasonal movement is normal. Persistent slope is not.
Water in the crawl space is a separate but related issue. Standing water means drainage problems, and drainage problems are what cause foundation issues in the first place. Even if your foundation looks fine now, untreated water in the crawl space will eventually cause settling, wood rot, and worse.
Why this matters in NC clay
The Piedmont sits on expansive clay that swells significantly when it gets wet and shrinks when it dries out. Every house in the Lake Norman area is built on soil that moves with the seasons, which is why some settling is normal in the first few years after construction. Older homes have usually settled into a stable position by the time they're 10 or 15 years old.
When older homes start showing new foundation symptoms, it usually means something has changed. A tree was removed and the soil is drying out faster, gutters stopped draining properly and water is pooling against the foundation, or the original construction had marginal footings that have finally given up.
Foundation repair is specialty work, and we don't do it. If you're seeing several of these signs together, you want a structural engineer or a foundation repair specialist to look at it. We're happy to walk a property and give you our honest opinion on whether what you're seeing is normal settling or something to take seriously, and we can refer you to people who handle the repair side.
For new foundations, footings, additions, ADUs, and detached structures, that's our work. Free on-site estimates for any new concrete project. Call (704) 313-8403 if you want to set something up.
