Pressure Washing Contractor Insurance: What It Actually Costs and Covers

General liability insurance for a pressure washing contractor typically costs $400 to $900 a year for a solo operator, with the market average landing around $727 a year.

How much does general liability insurance cost for a pressure washing business?

• Solo or small operator: roughly $400 to $900 a year ($39-$75/month)
• Market average: around $727 a year ($61/month)
• Larger crews doing commercial, roof, or chemical work: $3,000+ a year
• Bundled BOP (GL plus property): averaging $888 a year

$1 million per occurrence / $2 million aggregate is the standard floor for residential, HOA, and most commercial work, and property managers and GCs increasingly won't let you on-site without a valid certificate of insurance showing it.

Can I actually get fined for chemical runoff?

Yes, and most pressure washers don't know this exposure exists until they're hit with it. Detergent and surfactant runoff into a storm drain is treated by the EPA as an unpermitted discharge under the Clean Water Act, and penalties can exceed $37,500 per day, per violation. Some states, Florida among them, allow fines up to $50,000 a day for contaminated runoff reaching storm systems. Standard general liability policies carry a pollution exclusion, meaning chemical discharge from soft-washing isn't covered without a separate contractor's pollution liability endorsement.

Why won't some insurance companies cover roof cleaning?

Many standard general liability policies contain explicit language excluding any work performed on any part of a roof, regardless of the pressure or chemical mix used. Some insurers decline roof work outright; others will cover it only with documented soft-wash experience and safety protocols on file before binding the policy. Worth confirming directly before you take on roof cleaning jobs, not after a claim.

What property damage claims are most common in this trade?

Two come up constantly:

• Concrete etching ("zebra striping"): too much PSI or too-close wand distance permanently etches or pits concrete in a pattern that can't be repaired, only replaced.
• Siding and paint stripping: 1,500-3,000 PSI water routinely strips paint from siding, trim, and shutters, or drives water behind vinyl and wood panels, causing hidden rot and mold that doesn't show up until much later.

Both are real, recurring first-party property damage claims, not hypotheticals.

What licensing applies to pressure washing?

Most states, Texas, Florida, New York, Pennsylvania, Illinois, Ohio, Georgia, North Carolina, Michigan among them, require no special trade license for residential pressure washing, just general business registration. A few states have real teeth: Washington classifies pressure washing as a regulated specialty contractor requiring registration, bond, and insurance; Oregon requires a CCB license plus a surety bond above a dollar threshold; California requires a contractor's license for any job over $500.
