Signs of Foundation Problems: Spot the Red Flags Before They Cost More
If your home is wobbling, doors are sticking, or you see new cracks in walls, it might be more than normal wear and tear. Foundation issues start small but can turn into big, expensive headaches fast. Knowing the most common signs helps you act early, avoid costly repairs, and keep your house safe.
Common Visual Clues
1. Cracks in walls or floors – Hairline cracks are normal, but anything wider than 1 mm, especially if it grows, deserves a closer look. Look for stair‑step patterns in brickwork or horizontal cracks that run across a wall.
2. Doors and windows that won’t close properly – If they stick, bind, or warp, the frame may be shifting because the foundation is moving.
3. Uneven floors – A bouncy or sloping floor is a classic sign. Grab a level; a difference of more than 3 mm over a 2‑metre span is worth checking.
4. Gaps around window and door frames – Gaps that appear suddenly can indicate that the structure is pulling apart.
5. Water pooling near the foundation – Poor drainage can speed up settlement and cause rot or corrosion in the support walls.
6. Cracks in the exterior brickwork – Look for cracks that run horizontally or diagonally. These often signal lateral movement in the foundation.
When to Call a Professional
Not every crack means your house is about to collapse, but some situations need a structural engineer’s opinion. Call an expert if you notice any of these:
- Cracks wider than 3 mm in concrete or brick.
- Repeated movement – cracks that keep growing after you measure them.
- Signs of subsidence like leaning walls or a dropped ceiling.
- Persistent water seepage despite fixing gutters and downspouts.
- Any structural changes after a major storm or earth movement.
A professional will measure crack widths, assess soil conditions, and suggest the right repair method – from epoxy injections to underpinning. Knowing the exact problem helps you get the right insurance coverage too. Many house insurance policies won’t pay for foundation damage unless it’s caused by a covered event, so a detailed report can make a difference.
