Foundation Repair questions, answered by experts

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.

Foundation problems are costly to repair, but if you already own the home, you can either handle the issues or allow the property to (literally) sink into disrepair. The opposite is true when buying a home. Walk away if the seller refuses to lower the asking price once foundation issues are exposed or if they refuse to handle the problems before the completion of the sale.
