"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!!"

"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

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

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.

You could DIY the work, but unless you have plumber’s knowledge for identifying and fixing a slab leak and specialized equipment in your tool shed, attempting to DIY your slab leak repair isn’t a good idea. It’s simply not something that the average homeowner can take on themselves, regardless of how many successful DIY projects they’ve got under their belt. You could, however, do something simple like foundation waterproofing yourself to save some money on the post-repair work.

Crumbling concrete steps will affect your ability to drill into the material and affix a sturdy railing. If the damage is primarily cosmetic, you might be able to DIY the repair with a patch kit. If the concrete is badly crumbling, hire a professional who specializes in pouring concrete. The average concrete step repair cost is $500 from a professional, but the extent of the damage will determine your actual cost. The professional may recommend a replacement if the damage is extensive.

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.
