California businesses filed under foundation and waterproofing work, open and reviewed.
Roofers, plumbers and insulation companies with a side service were left out.
Services come from what each company says on its own site.
No answer on the site means "no information yet", never a guess.
Every listing starts from public business data for California companies filed under foundation and waterproofing work. We kept businesses that are open and have Google reviews, merged duplicates, and left out roofers, plumbers, insulation companies and other trades that list waterproofing only as a side service.
Then we read each company's own website and recorded the services it names, such as wall anchors, piers, drain tile, sump pumps or crawl space encapsulation. When a site does not say, the listing says so instead of guessing.

A crack in a foundation, a floor that has started to slope or water where it should not be is stressful, and the first company you call may not be the right one. Some companies listed here mostly fix foundations that have moved. Others mostly keep water out. Many do both. This guide covers what to look for before you sign anything.
Floors that slope, doors that stick or cracks that keep growing point to a structural problem that may call for piers, foundation jacking or wall repair. Water in a crawl space, garage or basement is usually a drainage or waterproofing job. California adds one more concern: the California Geological Survey maps the potential for earthquake ground shaking, fault rupture, liquefaction and landslides, and it publishes a Landslide Map Index you can use to look up your area. A good company will tell you which problem you have after an inspection, and many listed here say they offer that inspection for free.
California's Contractors State License Board licenses contractors. Work of $1,000 or more for labor and materials needs a licensed contractor, and so does smaller work that needs a permit. Contractors must put their license number on bids and contracts, but CSLB warns that seeing a number does not mean the license is valid. Look it up with CSLB's Check a License tool or call 800-321-2752. The listings on this site show whether a company states a license on its own website. This site does not check licenses.
A home improvement contract over $500 must be in writing and signed before work starts, and it must show the contractor's license number. The down payment may not exceed $1,000 or 10 percent of the contract price, whichever is less. In most cases you have three business days to cancel, and more after a declared disaster.
California's building code requires a permit to alter or repair a building or structure, and each city runs its own permit office. Ask the company who pulls the permit. If the job means digging outside, state law requires notice to 811 at least two working days, and no more than 14 calendar days, before digging starts. The ticket is free and good for 28 days. In Southern California the center is DigAlert; in Northern California it is USA North 811.
Each listing shows the services a company names on its own website: foundation repair, piers, crack repair, crawl space work, waterproofing, drain tile, concrete lifting and more. A service under "No information yet" means the company's site does not say. Call and ask.
Ask what they think is causing the problem and how they know. Ask which CSLB license class they hold for this work, what the warranty covers and whether it is in writing. Get at least two written estimates that describe the same scope of work.
Each listing is an open California business with Google reviews that does foundation repair, basement waterproofing or crawl space work. Roofers, plumbers and other trades that only list waterproofing as a side service were left out. Owners can claim a listing to fix details or add photos.
No. A basic listing is free. Companies can pay for a featured spot or a premium listing, and those are always marked as featured.
No. A listing shows whether a company states a license on its own website, but nothing here is verified. Check the contractor's license or registration with the official agency before you hire.
Waterproofing keeps water out of a basement or crawl space, with drain tile, sump pumps, crack sealing or encapsulation. Foundation repair fixes walls and footings that have moved, with wall anchors, braces or piers. Many companies here do both. Each listing shows which services the company names on its own website.
Yes, for most jobs. The Contractors State License Board requires a license for work of $1,000 or more, and for smaller work that needs a permit. Look up the license number with CSLB's Check a License tool before you sign.
California law requires notice to 811 at least two working days, and no more than 14 calendar days, before excavation starts. The ticket is free and good for 28 days. Ask your contractor whether they place the request.
