How to Verify California Foundation Repair Licensure (5 Steps)

For any and every construction project, it is imperative to ensure your contractor is appropriately licensed, bonded, and insured – but particularly when it comes to foundation repair.

Your foundation is the heart and soul of your home – any damage or failure puts your home in jeopardy.  

California requires every contractor performing northward of $500, including labor and material, to be licensed through the CSLB: Contractors State License Board.  

Our Ron Swanson readership might see this as government overreach and oversight (we’re not saying you’re wrong), but this process does provide legal protection for your home.

  • C-8 – CONCRETE

The two most important licenses when it comes to foundation repair are the A-General Engineering Contractors License and a C-61/D30 License (which specifically allows pile driving and foundation jacking).
