"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!!"

"After finding a crack in my drywall I searched for a contractor to inspect my foundation. I spoke with Maya in the office who was pleasant and helpful setting up a meeting. I'm glad I called as after the inspection I learned my home's foundation had deteriorated and I needed repair. Joseph started the project right away and completed my foundation within the time frame agreed. I would definitely use MVP again!"

"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!"

"This company did everything right. They showed up on time and did a beautiful job. Two of my neighbors watched and then asked Noke to give them estimates on work they wanted done. I would definitely recommend Top Concrete Design to anyone needed concrete work done. My driveway apron looks perfect now and I couldn’t be happier. Thank you ."

Foundation Repair FAQs, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
