Sinking Foundation? Quick Fixes and When to Call the Pros
If your floors feel spongy, doors won’t close, or you see cracks in walls, your foundation might be sinking. It’s a scary thought, but catching the problem early can save you a lot of money and stress.
What Causes a Foundation to Sink?
Most sinking foundations are the result of soil movement. When the ground beneath your house shifts, it can settle unevenly and pull the concrete slab down. Common culprits include:
- Heavy rain that saturates the soil, turning it into a soft mush.
- Improper drainage that leaves water pooling next to the house.
- Tree roots that pry apart the soil.
- Poorly compacted fill during construction.
Even a small change can create noticeable cracks or sloping floors. The key is to watch for the signs before they get worse.
Early Signs and Simple DIY Checks
Grab a level or a long straightedge and run it across several points on a floor. If it tips noticeably, you might have a slope. Look at the exterior walls for vertical cracks that start near the roof and move downwards—those often signal foundation movement.
Other quick checks:
- Test doors and windows. Hard-to-close frames usually mean the house is shifting.
- Check the garage; a concrete slab that feels uneven is a red flag.
- Walk around the perimeter and feel for soft spots in the soil, especially after rain.
If you spot any of these, don’t ignore them. Small problems can become big ones fast.
When DIY Isn’t Enough
There are a few things you can do yourself, like improving drainage, adding downspout extensions, or filling small cracks with epoxy. But if you see horizontal cracks, large gaps, or the entire house seems to be dropping, it’s time to call a professional.

Don’t wait for the next storm to reveal how bad it is. Get a qualified inspection, fix the drainage, and protect your home’s value.
Bottom Line
A sinking foundation is a serious issue, but early detection and swift action keep it from spiraling. Look for floor slopes, door problems, and cracks. Fix simple drainage problems yourself, but call in experts for anything beyond minor cracks. With the right help, you can stop the sinking and keep your home safe and solid.
