What carriers ask before they quote
Pressure washing claims usually involve damage to what's being washed or what's next to it: stripped paint, etched glass, water forced behind siding or windows, cracked roof tiles, or landscaping killed by soft wash chemicals. Many general liability policies exclude pollution, and wash water carrying chemicals can fall under that exclusion.
Many California cities restrict wash water going into storm drains, so how you capture and dispose of runoff matters to clients and carriers. Roof and ladder work also changes workers' comp and liability pricing. I place the work with carriers that accept it and check the exclusions before anything is bound.

- Height: whether you go on roofs and the tallest buildings you wash.
- Chemicals: what you apply and how you capture and dispose of runoff.
- Equipment: washers, tanks, trailers and their values.

Pressure washing insurance, answered
Does general liability cover damage from pressure washing?
It's meant to cover damage you accidentally cause to someone else's property, but many policies limit damage to the property you're working on and exclude pollution. The wording needs to fit the work you do.
Is soft washing covered?
It depends on the policy. Soft washing uses chemical solutions, and overspray or runoff that damages plants, cars or neighboring property can fall under a pollution exclusion. Disclose it and check that it's covered.
Does roof cleaning change my insurance?
Yes. Roof work brings fall risk for your crew and the risk of cracking tiles or forcing water under them. Some carriers exclude roof work, so it needs to be listed.
Do pressure washers need a contractor license in California?
It depends on the work. Washing alone is different from work such as painting, sealing or repairs that you might add to a job. Check the CSLB's rules for the services you offer.
Are my washers covered on the trailer?
Not by general liability. Washers, tanks and pumps are covered under an equipment policy, and the trailer itself needs to be on your auto policy.
Do you offer pressure washing insurance outside California?
Yes. Clients across the country send the same quote form. California policies are placed directly; outside California the request is handled together with a partner agency in your state, and the shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
Tell me what you wash. I'll shop it.
Your services, equipment and revenue are enough to start.
