Foundation Repair questions, answered by experts

Whether you need a permit for foundation repair depends on your location and the scope of the work. Major repairs like foundation stabilization typically require a building permit, while smaller projects such as sealing non-structural cracks or applying waterproofing solutions often do not. It's crucial that your contractor follows all local building codes, as an inspector will review the work to ensure it's up to standard. Failing to obtain the necessary permits can create issues when selling your home and may lead to further damage if the work is not done correctly. Your foundation repair specialist will usually know if a permit is needed and can handle the process for you. You can also contact your local building department or municipal office to confirm the requirements and verify that your contractor has filed the appropriate paperwork.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

Generally, foundation cracks and repair are not covered by standard homeowners insurance policies. This type of damage is often considered normal wear and tear or a result of poor maintenance, which is the homeowner's responsibility. For example, damage caused by settling, shifting soil, or drainage issues is typically excluded.

However, there are exceptions. Coverage may apply if the foundation damage is a direct result of a covered peril, such as a house fire, a burst pipe, vandalism, or a vehicle accident. Coverage for natural disasters like earthquakes and floods often requires a separate, specific policy or add-on.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.
