Contractors Pollution Liability Insurance in California
Fuel spills, sewage backups, mold, lead dust, drilling-fluid frac-outs, runoff into storm drains — pollution claims hit everyday trades, and most general liability policies exclude them. We place contractors pollution liability for California contractors, written to the limits your contracts require.
Why your GL probably doesn’t cover this
Most contractor general liability policies carry a pollution exclusion that removes coverage for bodily injury, property damage and cleanup costs caused by pollutants — with only narrow exceptions. Fuel, sewage, mold, lead, asbestos, silica, drilling fluid and runoff can all fall inside that exclusion. Contractors pollution liability (CPL) is the policy built to fill the gap.
What Contractors Pollution Liability Covers
- Third-party bodily injury and property damage caused by pollution conditions from your operations
- Cleanup and remediation costs, including costs required by a government agency
- Defense costs for covered claims
- Mold and bacteria, depending on the policy form
- Optional coverage for transporting materials and for waste you send to disposal sites
CPL can be written as an annual practice policy covering all your jobs, as a project-specific policy for a single large job, or packaged with general liability or professional liability depending on the carrier. Occurrence and claims-made forms are both available — which one fits depends on your work and your contracts.
Trades That Need Pollution Coverage
Working on fiber and directional boring or Class A general engineering projects? Pollution coverage is often a contract requirement on that work.
What Pollution Claims Look Like
Sewage backup
A plumbing crew’s line work backs sewage into a tenant space. The owner demands cleanup, mold remediation and lost rent.
Equipment fuel spill
A ruptured hydraulic line on an excavator soaks the soil on a commercial site. The owner requires excavation and disposal of the contaminated soil.
Frac-out
Drilling fluid from a directional bore surfaces in a creek bed. The agency orders cleanup and the property owner files a claim.
Lead paint
Prep work on an older building releases lead dust into occupied units, and tenants file bodily injury claims.
Examples are illustrations, not actual claims. Whether a loss is covered depends on the policy language.
When Contracts Require CPL
Public agencies, school districts, utilities, developers and many commercial general contractors require pollution liability in their subcontracts, often with specific limits, additional insured status and a requirement that coverage stay in place after the job is done. We read your contract requirements first and write the policy to match — and issue certificates within 24 hours once coverage is bound.
What We Need to Quote Pollution Liability
- Your trade and a description of the work you perform
- Annual revenue and the share subcontracted
- Limits required by your contracts, if any
- Any past pollution or mold claims
Need the rest of your program too? We place general liability, umbrella and commercial auto, workers’ comp and CSLB bonds alongside CPL.
Common Questions
Doesn’t my general liability policy cover pollution?
Usually not. Most contractor GL policies include a pollution exclusion that removes coverage for injury, damage and cleanup costs caused by pollutants, with only narrow exceptions. A separate contractors pollution liability policy covers those claims.
I’m not an environmental contractor. Do I really need CPL?
Many everyday trades create pollution exposure: plumbers with sewage and mold, HVAC with ductwork contamination, excavators with fuel spills, painters with lead. And many commercial and public contracts require CPL regardless of your trade.
Is mold covered?
Many contractors pollution policies include mold, but not all, and some limit it. Mold coverage is one of the first things we check when comparing policies.
What’s the difference between occurrence and claims-made CPL?
An occurrence policy covers pollution conditions that happen during the policy period, whenever the claim is made. A claims-made policy covers claims made while the policy is active, so keeping continuous coverage matters. Some contracts require one form.
Can I buy pollution coverage for just one project?
Yes. Project-specific CPL covers a single job for its duration, which some owners require on large or environmentally sensitive projects. An annual practice policy covers all your work.
