Coverage Types for Pressure Washing Companies
These are the key insurance policies most relevant to your business type — ranked by importance.
General Liability
RequiredCovers third-party property damage (broken windows, damaged siding, etched surfaces) and bodily injury (slip-and-falls from wet surfaces near your work area). GL is the non-negotiable foundation for any pressure washing business — client contracts, HOA agreements, and commercial property managers all require proof of GL before you start work. $1M per occurrence is standard.
Workers' Compensation
RequiredIf you have employees, WC is legally required in virtually all states. Pressure washing employees face slip hazards from wet surfaces, chemical burns from cleaning solutions, and struck-by risks from equipment. WC covers medical treatment and lost wages for work injuries — protecting both your employees and your business from financial exposure.
Inland Marine / Equipment
Highly RecommendedCovers your pressure washers, hoses, surface cleaners, chemical injectors, and trailer while on jobs, in transit, and when stored. Pressure washing equipment is expensive ($2,000–$15,000+ for commercial units) and theft-targeted. Standard commercial property coverage only covers a fixed location — inland marine covers tools wherever they are.
Commercial Auto
Highly RecommendedIf you drive a truck, van, or trailer to job sites, you need commercial auto — personal auto policies exclude commercial use. Trailers carrying pressure washers and chemical tanks need to be specifically scheduled on your commercial auto policy. A trailer-related accident on the highway without commercial auto leaves you personally exposed.
Pollution Liability
RecommendedPressure washing runoff can carry cleaning chemicals, oil residue, and other contaminants into storm drains — creating environmental liability exposure. Some commercial clients and municipalities require pollution coverage. This is especially relevant for parking lot cleaning, restaurant hood cleaning, and fleet washing operations.

What You Need to Know
- →Window damage is the most common pressure washing claim — high-pressure water can crack aged glass, force water into window frames, and damage seals. Use low pressure around all windows and use proper tips (25°–40°) on any surface near glass.
- →Surface damage claims are common — wrong pressure, wrong tip angle, or wrong distance from the surface can strip paint, etch concrete, or damage wood. Always assess the surface before applying full pressure.
- →Wet surfaces create immediate slip hazards — rope off the work area and post "wet surface" warnings near any active wash zone. A customer or passerby slipping on your wet driveway is a GL claim.
- →Chemical runoff liability is real — cleaning solutions containing sodium hypochlorite (SH) or other chemicals that enter storm drains can create environmental liability. Use best practices for containment and understand your local regulations.
- →Your COI (certificate of insurance) needs to be issued on request — commercial clients and property managers won't let you start without one. ERGO NEXT issues digital COIs instantly.
