What insurance does a pressure washing business need?
Start with general liability, then cover your vehicle, your rig and your crew. If you use cleaning chemicals or soft-wash, add pollution cover to the list, because general liability leaves that risk out.
| Coverage | What it pays for | Who needs it |
|---|---|---|
| General liability | Damage to client or neighbor property, injuries to other people, defense costs | Every pressure washer; clients ask for a certificate of insurance |
| Contractors pollution liability | Damage and clean-up from chemicals, overspray and runoff | Anyone using detergents, bleach mixes or soft-wash solutions |
| Commercial auto | Accidents involving the truck, trailer or skid rig | Anyone driving a vehicle for the business |
| Tools and equipment (inland marine) | Theft of or damage to pressure washers, surface cleaners, hoses and ladders | Anyone whose rig would be costly to replace |
| Workers' compensation | Medical bills and lost wages for injured employees | Businesses with employees, subject to state rules |
| Business owner's policy (BOP) | General liability plus property at a shop or yard | Businesses with premises and stored equipment |
| Umbrella | Extra limits above general liability and auto | Anyone whose commercial contract asks for higher limits |
Does general liability cover chemical overspray or runoff damage?
Usually not. The standard ISO general liability form (CG 00 01 04 13) treats cleaning chemicals as pollutants and excludes most damage they cause on a job:
- Exclusion f(1)(d) removes injury or damage from pollutants you bring onto a site where you are working.
- The form defines "pollutants" as any solid, liquid, gaseous or thermal irritant or contaminant, including "acids, alkalis, chemicals and waste".
- Exclusion f(2) removes costs of cleaning up pollutants when a regulator or anyone else demands or orders it.
So if bleach overspray kills a neighbor's hedge, spots a car or runs into a pond, don't expect a standard general liability policy to pay. Insureon says the same in plainer words: "Damage caused by cleaning chemicals or runoff is often excluded" (Insureon). The policy built for this is contractors pollution liability. Ask whoever quotes you whether they can place it; it may need a specialist insurer.
Policies can be endorsed differently, so read your own exclusions. The ISO form text is public in a state filing.
Will insurance pay if you etch the driveway you're washing?
Probably not. The same form excludes damage to "that particular part of real property" you are working on when the damage comes from your work (exclusion j(5)), and the cost of redoing work you did wrong (j(6)). Etched concrete, stripped paint or gouged siding on the surface you are cleaning usually lands in those exclusions. Damage to something else, like a window you break while washing the siding, is the kind of claim general liability is built for.
How each insurer and court applies these exclusions varies. Ask the insurer how its policy treats damage to the surface being washed.
Can you wash into the storm drain?
Usually not, and a fine or clean-up order is not something general liability is written to pay. Federal rules require cities with stormwater permits to "effectively prohibit, through ordinance" non-stormwater discharges into the storm sewer (40 CFR 122.34). The duty that reaches you comes from your city's ordinance, so check it.
State guidance shows what compliant washing looks like:
| State | What the guidance says | Source |
|---|---|---|
| Washington | Collect washwater and send it to the sanitary sewer, recycle it in a closed loop or haul it for treatment; plug storm drains; don't discharge to the ground, storm sewers or surface waters | WA Ecology washwater manual (vehicle and equipment washing, revised Nov 2012) |
| Oregon | Mobile cleaning with soaps or detergents on an impermeable surface, with wash water collected to the sanitary sewer or recycled | Oregon DEQ washing guidance (1998) |
| Florida | Only cosmetic washing unless you use a mobile zero-discharge closed-loop system | Florida DEP mobile washing BMPs |
These are guidance documents, some of them old, and the Washington and Florida documents are written for vehicle and equipment washing. We did not find a federal EPA rule written specifically for mobile pressure washing; the rules that bite are mostly local and state. Ask your city's stormwater office what it expects for house, roof and flatwork washing.
Do you need workers' comp for a helper on a ladder or roof?
If you have employees, check your state's rule. Texas lets most private employers choose whether to carry it (Texas Department of Insurance). Florida requires it from the first employee for construction businesses and from four for others (Florida DFS); ask your insurer which category your work falls into. Our workers' compensation guide covers other states.
The safety rules matter for claims too. OSHA requires employers with hazardous chemicals in the workplace to have labels and safety data sheets and to train workers (OSHA Hazard Communication), and that includes sodium hypochlorite. Portable ladders used to reach an upper landing must extend at least 3 feet above it (29 CFR 1926.1053(b)(1)).
Is soft washing roofs covered under the same policy?
Ask before you take the job. Roof work can be classified differently from flatwork and house washing, and an insurer prices and covers you based on the work you declare. List roof cleaning on your application if you do it, even occasionally.
Is your pressure washer covered if it's stolen from a job?
Not by general liability. Tools and equipment cover (inland marine) pays for stolen or damaged rigs, surface cleaners and hoses, on site or in transit. Check the limit: NEXT's basic pressure washing tier includes $3,000 of tools and equipment cover (NEXT, read October 10, 2026), which may not replace a trailer rig. Ask whether a trailer-mounted unit sits on the auto policy or the equipment policy.
How much does pressure washing insurance cost?
Pressure washing businesses that buy through Insureon pay a median of $73 a month ($879 a year) for general liability with a $1 million per-occurrence and $2 million aggregate limit and a $500 deductible. Insureon calls these figures averages; its method note says they are medians of policies bought by its own pressure washing customers.
| Policy | Median monthly cost (Insureon pressure washing customers) |
|---|---|
| General liability | $73 |
| Workers' compensation | $147 |
| Commercial auto | $262 |
| Business owner's policy ($1,000 deductible) | $142 |
| Commercial umbrella | $76 |
| Janitorial bond | $9 |
Source: Insureon pressure washing insurance cost, updated September 8, 2026, read October 10, 2026.
The BOP figure stands out: $142 a month, against $83 for Insureon's carpet cleaning customers and $77 for its janitorial customers. For window cleaning, see window cleaner insurance costs.
Check the limit as well as the price. NEXT's pressure washing page shows a "Basic" tier with $300,000 of general liability per occurrence and a "Pro" tier at $1 million. If a commercial client asks for $1 million, the basic tier won't meet it.
Can you pressure wash without a license?
We did not find a state license written specifically for pressure washing, though we didn't check every state. You may still need a business license from your city or county. Some states treat work on structures as contractor work above a dollar limit; our handyman license table lists the thresholds we verified. Check your state contractor board if you do repairs as well as cleaning.
Will California's small-engine rules affect your equipment?
If you work in California, yes, when you replace large gas units. The California Air Resources Board's rule makes new pressure washers with engines of 225cc or more subject to a zero-emission standard from model year 2028; you can keep using equipment you already own (CARB, December 2021). CARB committed to reviewing the technology before then, so check the current rule before you buy a new rig.
What to have ready when you get quotes
- What you wash: houses, roofs, decks, flatwork, fleets
- Whether you use chemicals or soft-wash, and how you handle runoff
- How many people you employ and your payroll
- Vehicles, trailers and the value of your rigs
- Any liability limit or additional insured wording a client contract requires
The form on this page doesn't promise pollution cover, so ask about contractors pollution liability separately if you use chemicals. When you're ready, compare business insurance quotes across providers.
Frequently asked questions
What insurance do you need for pressure washing?
General liability, commercial auto for your truck and trailer, tools and equipment cover for the rig, and workers' comp once you hire (state rules vary). If you use chemicals or soft-wash, add contractors pollution liability, because standard general liability excludes most chemical damage.
How much does pressure washing insurance cost?
Insureon's pressure washing customers pay a median of $73 a month for general liability, $147 for workers' comp, $262 for commercial auto, $142 for a BOP and $76 for an umbrella (September 2026 figures).
How much is $1 million liability insurance a month for a pressure washer?
Insureon's pressure washing customers pay a median of $73 a month, or $879 a year, for general liability with a $1 million per-occurrence and $2 million aggregate limit. Cheaper online tiers can carry lower limits, such as NEXT's $300,000 basic tier.
Does general liability cover chemical overspray or runoff?
Usually not. The standard form treats chemicals as pollutants and excludes damage from pollutants you bring to a job, plus regulator-ordered clean-up costs. Contractors pollution liability is the policy for that risk.
Can I wash into the storm drain?
Usually not. Cities with stormwater permits must ban non-stormwater discharges by ordinance, and state guidance in Washington, Oregon and Florida tells mobile washers to capture washwater. Check your city's ordinance, and don't expect general liability to pay a fine or clean-up order.
Can I pressure wash without a license?
We did not find a pressure-washing-specific state license, but you may need a city or county business license, and some states treat work on structures as contractor work. Check your state contractor board.
