Foundation Repair questions, answered by experts

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.

Most building departments will require that a certified and licensed foundation repair professional or a structural engineer pull permits for foundation repair, so homeowners usually cannot pull them themselves. This helps ensure that an experienced professional completes all structural work on your home. Minor repairs that are technically DIYable often won’t require permits, but it’s still a good idea to hire a professional to carry out foundation repairs.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.
