Foundation Repair questions, answered by experts

Foundation problems will likely get worse over time if they aren’t repaired. As foundation problems progress, your home may experience signs of structural damage, water damage, and health and safety risks—all of which will only get more expensive to fix the longer you wait. Repair foundation problems as soon as you’re aware of them to avoid complex and expensive remediation in the future.

No, foundation repair is not usually covered by home insurance. Most home insurance companies typically consider foundation repair as part of your home maintenance, so they won’t cover the cost. However, foundation damage is sometimes caused by covered events such as a burst pipe or a house fire. In these cases, repairs may be covered.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

Yes. A foundation wall can usually be replaced, but you’ll want to call a foundation professional.

Although it is possible for a house to collapse from a sinking foundation, it will likely take many years, and signs of major issues will be apparent for a while. Homes on hillsides or in areas that experience frequent washouts are at a higher risk of collapse. Still, barring a natural disaster or extreme circumstances, houses are unlikely to fully collapse from foundation damage.
