Foundation Repair questions, answered by experts

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

Yes, a house can collapse from severe foundation problems if left unchecked, which is why it’s so important to carry out routine foundation inspections and call for repairs at the first sign of an issue. Foundation cracks often take years to get to the point where your home is at risk of collapsing. Implementing a solution quickly, even if your issue seems minor, is always worthwhile.

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.

It is possible for a slab leak to cause a sinkhole, but it would have to be a particularly serious leak. A slab leak causes the land under your home to erode and if there is enough movement depressions will form in the ground, potentially causing a sinkhole.

There are many actions that specialists can take to repair a bad foundation. However, just like a car, a specialist will determine whether the cost of repairs is worth it in the long run. In many cases, repairs to the surrounding property—such as regrading your lawn or addressing lawn drainage issues—will also be necessary.
