What insurance does a pressure washing business need?
Pressure washing is low-cost to start but easy to get wrong. Too much pressure, the wrong nozzle or the wrong chemical can damage a client's home in seconds. That is why general liability is the first policy most pressure washers buy. It covers third-party property damage and bodily injury, plus advertising injury.
Your equipment is the second big risk. Tools and equipment insurance (inland marine) covers washers, pumps, hoses and surface cleaners wherever they are. Commercial auto covers the truck that tows your rig. Once you hire help, workers' compensation covers employee injuries.
How much does pressure washing insurance cost?
Pressure washing falls under cleaning services. According to Insureon's 2026 data from 100,000 small-business customers, cleaning businesses pay a median of $48 a month for general liability, $76 a month for a business owner's policy and $136 a month for workers' compensation.
Your price depends on:
- Services: roof soft washing and commercial work usually cost more to insure than driveway cleaning
- Chemicals used
- Equipment value and vehicles
- Payroll and crew size
- State, claims history, limits and deductibles

Example claims (illustrative)
- Example: High pressure strips paint and gouges cedar siding on a client's house. General liability can help pay for repairs.
- Example: Water forced past an old window seal damages drywall inside. General liability may respond, depending on the policy.
- Example: A soft-wash mix drifts onto a neighbor's prize roses and kills them. Coverage depends on how your policy handles chemicals and pollution.
- Example: Your trailer-mounted unit is stolen from your driveway. Tools and equipment coverage can help replace it.
Is insurance required for pressure washers?
Insurance is not usually required by law for a solo operator, but HOAs, property managers and commercial clients often require a certificate of insurance. Workers' comp is required in most states once you have employees; see workers' comp requirements by state. Some cities also regulate wastewater runoff, so check local rules.
Pollution and runoff: read the exclusions
Many general liability policies contain a pollution exclusion. If you use detergents, degreasers or bleach-based soft-wash mixes, ask your insurer how runoff and overspray claims are handled and whether you need extra coverage. Getting a clear answer before a claim is far better than finding out after.
Residential vs. commercial pressure washing
Residential jobs like driveways, decks, siding and fences carry a high risk of surface damage, because homes vary so much in age and materials. Older paint, soft woods and aging window seals are easy to damage.
Commercial jobs such as storefronts, parking garages, fleet washing and restaurant hood or dumpster-pad cleaning often involve degreasers, larger equipment, after-hours work and stricter contracts. Commercial clients typically require a certificate of insurance, set minimum liability limits and may ask to be named as an additional insured.
Water damage and hidden defects
Some of the most expensive pressure washing claims involve water getting inside: past window seals, under siding or through gaps in older buildings. Walk the property with the client before you start, point out loose siding, cracked seals and peeling paint, and photograph everything. Written notes and photos make it much easier to show what existed before your work.
Working at height
Second-story siding, gutters and roofs bring ladder and fall risks. If you employ people, workers' comp is your main protection against these injuries. Some general liability policies also restrict work above a certain height or on roofs, so ask before you buy if you offer roof soft washing or gutter brightening.
Certificates of insurance
HOAs, property managers and commercial clients will ask for a certificate of insurance (COI) that shows your coverage, limits and policy dates. Choose an insurer that can issue certificates quickly, ideally online, so you don't lose jobs waiting for paperwork.
Questions to ask before you buy
- Is there a pollution or chemical exclusion, and can I add coverage?
- Are roof soft washing and work at height covered?
- Is my trailer-mounted equipment covered while towing and while parked?
- How are water intrusion claims handled?
- Can I add clients as additional insureds?
Solo operator vs. growing crew
A solo operator usually starts with general liability, equipment coverage and auto coverage that allows business use. Workers' comp often isn't required yet for a one-person business, though some clients still ask for it.
As you add employees, your needs change. Most states require workers' comp once you reach the state's threshold, and you'll want commercial auto for every vehicle the business owns. If helpers drive their own cars to jobs, hired and non-owned auto (HNOA) coverage can protect the business. Review your policies each time you hire, buy a new rig or add a service like roof washing or fleet washing, and tell your insurer about the change.
How to lower your premium
- Train every operator on pressure settings, nozzles and surfaces.
- Take before-and-after photos of each job to document existing damage.
- Use runoff controls and follow local wastewater rules.
- Store equipment in a locked garage or use trailer locks.
- Bundle policies where possible and pay annually if discounted.

Frequently asked questions
What insurance does a pressure washing business need?
Most pressure washers carry general liability, tools and equipment insurance and commercial auto, plus workers' compensation once they hire. If you use chemicals, ask whether your policy excludes pollution and runoff claims.
How much does pressure washing insurance cost?
Pressure washing is grouped with cleaning businesses. Insureon's 2026 data shows a median of $48 a month for general liability and $136 a month for workers' comp. Your cost depends on services, chemicals, equipment, payroll and location.
Does general liability cover damage from pressure washing?
General liability usually covers accidental damage to a client's property, such as stripped paint or a broken window, subject to the policy terms. It does not cover your own equipment or the cost of redoing your work.
Do I need insurance for soft washing roofs?
Roof soft washing uses chemicals and involves ladder or roof work, so insurers may rate it as higher risk. Disclose it when buying coverage, and ask about pollution exclusions and any roof-work limits in the policy.
Is my pressure washer covered if it's stolen?
Not under general liability. You need tools and equipment (inland marine) insurance or property coverage to protect washers, pumps, hoses and trailers.
Do pressure washing companies need workers' comp?
Most states require workers' comp once you have employees, with thresholds that vary by state. Even when not required, it protects you from the cost of employee injuries.
