Drywall contractor insurance in California

Where drywall jobs lead to claims

Drywall looks low risk until a screw finds a pipe. General liability (GL) pays when your work injures someone else or damages property that is not yours. These are the claims drywall contractors see:

• Punctured pipes and wires. A screw or nail through a water line behind the board can leak for weeks before anyone sees it. By then the wall, floor and the unit below are damaged.
• Dust and overspray. Sanding dust and texture overspray on an occupied home's furniture, flooring, HVAC system or a neighbor tenant's inventory.
• Trip and fall. Stacked board, buckets, cords and scaffolding in a home or an open office where people still walk.
• Completed operations. Ceilings that sag or come loose after the job is finished, or fire-rated assemblies that were not built to spec.
• Damage to other trades' work. Gouged door frames, broken windows or cracked tile from moving board through a finished space.

Ladders and stilts are where your own crew gets hurt, but those injuries are a workers' comp matter, not GL. GL also does not cover your tools, your truck, or the cost to re-hang or re-finish work that was wrong.

What commercial GCs and property managers ask for

Much of drywall work is commercial tenant improvements (TI): offices, stores and medical suites inside occupied buildings. Those contracts come with strict insurance terms:

• A certificate of insurance (COI) with GL of $1M per occurrence / $2M aggregate. Some commercial jobs ask for higher limits through an umbrella, which Aster quotes by phone.
• Additional insured status for the GC, the building owner and often the property manager, on ongoing and completed operations.
• Primary and non-contributory wording and a waiver of subrogation.
• Proof of workers' comp before badging onto the site.

Homeowners on residential jobs usually just want to see that you carry GL. A certificate holder is not an additional insured; our certificate of insurance guide explains the difference.

Exclusions to read for in a drywall policy

• Mold and fungi. Many GL policies exclude mold. Drywall is where mold grows after a leak, so a mold exclusion can cut deep into a water claim. Read it closely.
• Water damage. Check whether the policy limits or excludes water damage, especially from leaks that are found late.
• Tract homes, condos and multi-family. Some policies exclude residential new construction of these types because of construction-defect suits.
• Height and scaffolding. Some policies limit work above a set height or number of stories.
• Classification. If you also do framing, metal studs, insulation, painting or acoustical ceilings, say so in the questions so the policy matches the work. Work outside your class may not be covered.
• Contractual liability. TI contracts often include indemnity clauses. Check that the policy covers the indemnity you sign.

Every quote on our board lists what is included and excluded, so you can compare before you submit.

CSLB rules for C-9 drywall contractors

This is general information from the CSLB, not legal advice.

• Workers' comp. Every licensee files a workers' comp certificate or an exemption with CSLB (B&P §7125). A C-9 with no employees may file the exemption today. Under current law, workers' comp becomes required for all licensees on 1/1/2028 (SB 216, delayed by SB 1455). See our workers' comp guide.
• LLC licenses. An LLC must carry liability insurance with an aggregate of at least $1,000,000 if 5 or fewer people are on the personnel of record, plus $100,000 per additional person, up to $5,000,000, from a California-admitted or eligible surplus line insurer. See the LLC requirement.
• Other entities. CSLB does not require GL by law for non-LLC licensees but strongly recommends it. Commercial GCs require it by contract.
• Home improvement contracts. When you contract directly with a homeowner, the contract must include a "Commercial General Liability Insurance" notice with your insurer and phone number, or state you have no CGL (B&P §7159 / §7159.10).
• Small jobs. Since 1/1/2025, unlicensed work is allowed only under $1,000 in labor and materials, with no permit and no hired help.

How the online quote works from your license number

1. Enter your CSLB license number. We find your business in the CSLB public record and show how many A-rated insurance companies write C-9.
2. Confirm you are the owner with your name, mobile and email.
3. Answer about a minute of tap-to-answer questions: homes or businesses, new construction, sales, payroll, subs, crew, years, claims, current insurance and start date.
4. Your quote board shops A-rated programs live. Prices arrive one by one with deductible, limits, and what is included and excluded. The link is also texted and emailed.
5. Tap "Submit for approval." A licensed agent handles it. Approval usually takes 30 minutes to 4 hours depending on the carrier, and the final quote is emailed to you to sign.

Nothing is bound until you sign. Once you are covered, we send the certificate to your GC. Your price depends on sales, payroll, residential versus commercial, new construction share, subs and claims. See what drives it in our cost guide, or browse the insurance by trade page.
