Signs Your Foundation May Be Settling
Settlement is uneven: one part of the house drops while the rest stays put. The damage follows that line of movement. Here is what to look for inside and out.
Inside the house
- Diagonal cracks running out from the top corners of door and window frames
- Interior doors that have started sticking or will not latch, and gaps opening at the top corner of a door frame
- Gaps between the wall and the ceiling, or the floor pulling away from the baseboard
- Floors that slope or sag toward one part of the house
- Cracks in tile or grout lines that keep opening
- Nail pops and cracked drywall seams appearing in a pattern, not randomly
Outside the house
- Stair-step cracks in brick or block that step down along the mortar joints
- A gap opening between the brick and a window or door frame
- The chimney tilting or separating from the house
- Cracks where the porch, steps, or garage meet the main structure
- Doors and windows visibly out of square from the outside
- A visible dip in the roofline or fascia along one section
A quick self-check
Put a ball or a round pencil on the floor in a few rooms. If it rolls the same direction every time, part of the floor is lower. Check whether the low direction lines up with the cracks you have been seeing. Take photos of cracks with a coin for scale and the date, so you can tell later if they are growing.
What settlement is not
Not every crack is settlement. A single vertical crack in a poured wall is usually shrinkage. A horizontal crack is usually wall pressure, not settlement. Uniform hairline cracks throughout a new home are often just curing. Settlement shows up as a pattern of movement concentrated on one side or corner.
Why it matters to act
As long as the soil under the footing keeps moving, settlement usually continues. Caught early, a few piers under the affected area can stabilize the house and often lift it back, closing many of the cracks. Left for years, more of the structure is affected and the repair gets bigger.
What to do next
If you are seeing a pattern that points to one side of the house, get it inspected. We measure the actual movement and tell you whether it is active and what the repair involves.
