Foundation Warning Signs Quiz for Durham, NC Homes
A new crack or a door that drags in Durham, NC is not proof that a foundation has moved. The City of Durham describes the soil in parts of the area, weathered from ancient Triassic rock, as "very clay-rich, non-draining", and clay like that can swell when wet and shrink as it dries. The five questions below place what you notice in one of three results.
- No Cost to Request
- Written Estimates
- Local to Durham County & Nearby
- Crawl Space & Slab Homes
Using This Tool Well
Base each answer on what the house shows right now. Start outside: walk the brick, block or siding at the base of each wall, then go indoors to the rooms where doors catch or windows stick. A credit card is a handy gauge for crack width, and a marble on a hard floor shows which way the floor leans. Step 2 takes more than one answer, and "Not sure" is always a fair pick.
Homes across Durham County sit on slabs and over crawl spaces, and both can show the same signs. If you can safely look into a crawl space, note any standing water or damp wood. After a long soaking, such as the 6 to 10 inches Tropical Storm Chantal dropped on Durham County and its neighbors in July 2025, it makes sense to look again for new cracks. Think of the result as a signpost; it does not diagnose anything.
