Pollution Liability Insurance
Pressure washing generates wash water carrying detergents, sodium hypochlorite, oils, and debris. When that runoff reaches storm drains or waterways, it creates pollution exposure that GL excludes. Contractor's pollution liability (CPL) fills that gap.
Pollution Liability for Pressure Washing Contractors
Every general liability policy contains a pollution exclusion — and pressure washing is one of the trades most exposed by it. The wash water you generate carries surfactants, sodium hypochlorite (SH), degreasers, oils, paint chips, and organic debris. When that water enters a storm drain or waterway, it can trigger an EPA Clean Water Act violation and a pollution claim that your GL will not touch.
What Pollution Liability Covers
- Runoff & discharge claims: Wastewater carrying chemicals or contaminants into storm drains, soil, or waterways
- Cleanup costs: Remediation and environmental cleanup you're ordered to perform
- Regulatory fines & defense: Defense against EPA and state environmental agency actions
- Third-party bodily injury & property damage arising from pollutants
- Chemical spills: Accidental release of the detergents and chemicals you transport and use
Why GL Isn't Enough
Many contractors assume their general liability covers "anything that goes wrong." It doesn't. The pollution exclusion is absolute for environmental claims, leaving you personally exposed to cleanup costs and fines that can reach five or six figures. Contractor's pollution liability (CPL) is purpose-built to close that gap.
Best Practices Lower Your Risk
Carriers look favorably on contractors who manage runoff responsibly — using wastewater reclamation and recovery systems, berms and vacuum recovery, and following local discharge regulations. These practices reduce both your environmental risk and your premium, and they keep you compliant on commercial sites that demand it.
What's Covered
Frequently Asked Questions
No. Every GL policy has a pollution exclusion that specifically removes coverage for environmental claims like runoff and chemical discharge. Pressure washing contractors need a separate contractor's pollution liability (CPL) policy to be protected.
In most cases, yes. Even biodegradable detergents and the dirt, oils, and debris you remove can be considered pollutants when they reach a storm drain. Many commercial clients also contractually require pollution coverage before hiring you.
