"They were good. Matt was our inspector. We needed to get an inspection done on a new home and they came out with little notice and gave us a great breakdown and report. We are looking to hire them for the foundation repairs so I will let you know how the service goes beyond the inspection!"

"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!!"

"MVP Remodeling did an amazing job repairing our slab foundation. We also needed new stucco and exterior paint as part of the project and they did great with that too! Josef went above and beyond my expectations. He had amazing communication before, during, and after the repair and the painting. Super professional, the team was here every day on time, and always left everything clean after them! I’m so excited to partner with them for my next project, thank you, Josef!"

"Sept 2020 =Paramount Pavers replaced our ugly cracked circular driveway with beautiful Belgard pavers. We selected Paramount pavers because of the excellent reviews on Angie's list. Isaac was always responsive and answered many of our questions. Can't find many contractors like him. The employees consistently came to work for 10 days. They did a beautiful job. Minor issues: the transformer to the step lights had to be replaced after 2 days and broken sprinklers were replaced. Highly satisfied. Highly recommend. See also my Yelp review that included pictures."

"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."

"HIC builders is a family owned company, and they did a terrific job at my house. We added an ADU above the garage, remodeled two bathrooms, and did other extensive work on the house. Abraham, the field manager, was responsive and available, flexible when plans needed to change to accommodate structural issues that we discover as the project progressed, and answered my endless questions. The workmen were always on time, courteous, and cleaned up the site every day before they left. Probably the easiest way to find out if HIC can provide what you want is to call Abraham Moryossef directly (818 850 5062) and chat. I know it will be a good investment of your time. They are terrific!"

Foundation Repair FAQs, answered by experts

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

It depends on the bank and the extent of the issue. Some banks will lend against homes with minor foundation damage, but most won’t if the issue is structural since the home acts as collateral for the mortgage. Banks that offer renovation loans might still finance a home with structural problems. More minor issues like settling cracks and intermittent problems with humidity are unlikely to stop a bank from financing.

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.

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.

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.
