"From start to finish our experience with Foundation Works was top notch. We did contract them to bolt the foundation on our 1921 Spanish Bungalow home and repair some minor foundation cracks in a 1950's addition. Prior to calling Foundation Works we had two other estimates for work, one was in line with the quote provided by Foundation Works and one was higher with a few additions to the work. So I would say their price was in parity with others. Myron did our initial inspection and spent a lot of time crawling around under our home and doing a very detailed inspection. He spent a long time sitting with us afterwards discussing what he discovered and what he recommended. He was very patient with our many questions. When we tried to add some additional work reinforcing what looked like some long term slippage on the peers under the house he carefully informed us of the history of how houses like ours were built and why we did not need to spend more money doing this repair as it wasn't slippage but rather just how it was built. Once we accepted the bid FW was able to start work quickly. They worked cleanly and while they don't clean up every day before going home they also don't leave a bad mess and the work was all in the backyard so a few piles of tools was not a big deal at all and was painless. The team that did our work was professional, friendly, and efficient. When we had questions they were always there to answer. When we had one (very small) issue related to the nails originally used in the 1920s to hold the corner floorboards in which had jumped up a bit due to the installation of blocks needed to support the bolting in a few places, they stopped work, immediately fixed the issue and adjusted how they worked so it didn't happen again. When the work was done you wouldn't even have known they were here. The yard and all entry points to the crawl space were spotless. The Burbank city inspection was a few days later, they handled it completely and we never needed to worry about a thing until they handed us approvals. The back office and payment process was professional, pleasant, and very low touch. I can't recommend this company more highly."

"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

Foundation Repair questions, answered by experts

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.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

Periodic sealing and cleaning to maintain appearance and integrity.

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.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.
