"I highly recommend Titan Foundation Repair. I had gotten multiple inspections/quotes from bigger companies who were wanting to do unnecessary expensive work in my crawlspace. Jon identified the water issue I was having in my foundation and gave knowledgeable explanations. The work done was priced fairly and well done! I will be using Titan Foundation repair again for future projects."

"We had a section of our walkway "mudjacked" at few years ago. That repair did not last, so we decided the best remedy would be to replace the walkway. We called Legacy and Cindy came out promptly to provide us with an estimate. The estimated was reasonable and included a solution to our drainage problem that had caused the sidewalk to "sink". The work was completed promptly and ahead of schedule. The crew was polite and competent. The Walkway turned out great! I will definitely use Legacy Concrete again!"

"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."

"It went great! They were awesome. The service was high quality. Adrian was extremely helpful and had great idea of what the final outcome would look like. They were very responsive and efficient. They accidentally messed up part of my back fence when completing the project and Adrian came back personally to complete a repair! I would highly recommend them to others."

Foundation Repair FAQs, answered by experts

Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.

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.

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.
