7 Signs Your Home May Have Foundation Problems

Foundation problems are one of the most common - and most stressful - issues Triangle homeowners face. North Carolina's expansive clay soils, seasonal moisture changes, and aging housing stock create the perfect conditions for foundation movement.

Here are 7 signs that your home may have foundation problems:

1. Cracks in Interior Walls or Ceilings - Diagonal cracks radiating from door and window corners are a classic sign of differential settling. While hairline cracks can be cosmetic, wider or growing cracks warrant professional evaluation.

2. Sticking Doors and Windows - When a foundation shifts, door and window frames go out of square. If doors that used to close smoothly now stick or won't latch, foundation movement may be the cause.

3. Uneven or Sloping Floors - Place a ball on the floor. If it rolls consistently in one direction, your floors may be out of level due to foundation settling or crawl space issues.

4. Gaps Between Walls and Ceiling or Floor - Visible gaps where walls meet ceilings or floors indicate structural movement. These gaps often worsen over time if the underlying cause isn't addressed.

5. Exterior Brick Cracks - Stair-step cracks in brick mortar joints are a telltale sign of foundation movement. These are especially common in homes built on clay soils in the Triangle.

6. Bowing or Leaning Walls - Basement or crawl space walls that bow inward suggest lateral soil pressure. This is a serious structural concern that requires engineering evaluation.

7. Water Intrusion or Moisture in Crawl Space - Persistent moisture in your crawl space can deteriorate structural framing and accelerate foundation problems. It's both a symptom and a contributing factor.
