"I hired Dalinghaus Construction to install two push Piers for a freestanding column/wall (bad clay soil causing movement). I meet with Kevin to go over the scope of work and he explained everything in detail. The price was the best I can find. Took one extra day to finish the work, but they did not charge me any additional fees. 3 month later, I had a feeling that the column/wall is moving again and call Kevin. He show up in a few days and show me there is no way that wall is still moving and he was right. They are very good at what they do and customer service is the best. Thank you very much."

"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"This was an usual project. It was redoing a mini bar. Hard to find a contractor that would do it or had the time. Homepro was great lead by project manager Shir Hadad. Jumped right in there and took it on and got the job done. Really appreciate their professionalism."

Customers say: Terrific value

"Todd and the WestPro crew did a very fine job in a difficult working conditions. We had them repair portions of our crawlspace foundation and our perimeter stem wall as well as well as some slab and curbing work in the garage area. Todd shows up when he says he will and goes over everything very carefully with the guys so they are less likely to miss details. Very hard working guys. When he gave me the quote, there was no guess work. He crawled around and measured everything. I wish I could say this about other contractors."

Foundation Repair FAQs, answered by experts

Minor slab leaks normally take around three hours to access and fix, provided the leak is in an accessible location. However, a more extensive leak or a leak in a hard-to-reach location can take several days to fix, depending on the resulting damage. You might also want to consider the timeline for the build-back if the leak damages building materials like flooring or cabinets, which can take several weeks, including delivery of the materials.

The average cost to repair a concrete driveway ranges from approximately $830 to $2,800, with a typical project costing around $1,765. The price varies widely depending on the type and extent of the damage. Minor crack repairs can be as low as $0.10 to $0.15 per linear foot and may be a DIY project. More significant repairs are priced per square foot: replacing a damaged slab costs about $6 to $14, while raising or leveling sunken concrete costs $3 to $25. Resurfacing is another option, costing around $3 to $5 per square foot. Factors influencing the total price include the size of the affected area, whether reinforcement is needed, and labor costs.

Violating building codes can lead to a number of consequences, including fines, citations, and even being required to demolish the structure and start over. If your house isn’t compliant with code requirements, you can also run into trouble when it comes time to get homeowners insurance or sell your house. Following all applicable building codes will avert costly consequences.

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.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.
