What most NEXT pressure washing customers pay, data updated October 2026
Insureon’s medians for pressure washing customers who buy through it come to about $879 a year for general liability, $1,761 for workers’ comp and $3,143 for commercial auto, with a business owner’s policy at $1,699. Most of those customers have fewer than five employees and five years or less in business. NEXT says 86% of its pressure washing customers pay about $75 a month for general liability, and most pay $57 to $300 depending on limits of $300,000 to $1 million per occurrence. Insureon notes large commercial properties cost more to insure than residential work, and employees, vehicles and higher contract limits add to the bill.

Risks
The risks insurers price for
A pedestrian slips on a wet walkway
Water and cleaning solution leave sidewalks, entrances and pool decks slick. The Hartford says slips, falls and customer injuries were the third most common type of claim small business owners faced in 2025, and storefront jobs put the public beside your spray.
Spray strips paint, gouges siding or cracks a window
Too much pressure or the wrong tip can etch wood, strip paint, force water behind siding or crack glass. Progressive and The Hartford both use damaged siding, paint and windows as their examples of what a pressure washing liability claim looks like.
Wash water runs into a storm drain
Ohio EPA treats power washing wastewater as industrial wastewater under the Clean Water Act, even with biodegradable soap. Letting it run into a storm drain, ditch or creek without a permit is a common violation it sees, and it can bring fines.
Stripping paint from a pre-1978 house
Washing loose paint off an older home can spread lead. EPA requires firms paid to disturb paint in pre-1978 homes and child-occupied facilities to be lead-safe certified, and wash water may not carry debris out of the contained work area.
A gas engine running in a garage or warehouse
NIOSH warns that gasoline-powered pressure washers produce carbon monoxide that builds up quickly indoors; it documented one death and four poisonings from washers run inside farm buildings. Keep the machine outside on garage and warehouse jobs.
The rig is stolen from the truck or trailer
Washers, surface cleaners and pumps sit in an open trailer or truck bed at job sites and overnight. The Hartford and Progressive both use stolen equipment as an example claim, and replacing your own gear takes tools and equipment coverage.
Coverage
Coverage to consider
General liability
Pays for injuries to the public and damage to client property, such as a passer-by who slips on a wet walkway or paint stripped from a house. Insureon’s typical pressure washing policy carries $1 million per occurrence, $2 million aggregate and a $500 deductible.
How general liability works →Commercial auto
Covers the truck or van that tows your trailer and tanks. Progressive notes personal auto typically does not cover business use, and Insureon says most states require commercial auto for vehicles a business owns.
How commercial auto works →Tools and equipment
Inland marine coverage for washers, surface cleaners and pumps that are stolen, vandalized or damaged while stored or moved. NEXT’s pressure washing customers typically pay $30 a month for $3,000 to $5,000 blanket limits; a trailer rig may need more.
Workers’ compensation
Covers crew injuries such as the example The Hartford gives of a worker who hurt a knee lifting the washer into the truck. Insureon says state laws typically require it once you have employees.
How workers’ compensation works →Business owner’s policy
Bundles general liability with property coverage for a shop or storage building, plus business income after a fire or storm. Insureon’s pressure washing median is $142 a month.
How commercial property works →Janitorial bond
Reimburses a client if an employee steals from the property, which some commercial contracts require. Insureon puts the median at $9 a month; unlike insurance, you repay the surety for any claim.
Pollution liability
Runoff, overspray and contaminated wash water are where washing claims get disputed. Ask how your general liability policy treats pollution and, if it limits it, whether contractors pollution liability fits your work.
Umbrella or excess
Adds limits in $1 million steps above general liability, auto and employer’s liability when a contract asks for more. Insureon’s median for cleaning businesses is $76 a month.
How umbrella / excess works →Rules
Requirements and filings
No federal license covers pressure washing, but environmental, lead paint and workers’ comp rules reach the work, and commercial clients set their own insurance terms.
| Requirement | Applies to | What it means |
|---|---|---|
| Wash water discharge | Mobile power washing companies in Ohio | Ohio EPA, June 2025: wash water is industrial wastewater under the Clean Water Act. Keep it out of storm drains; use a sanitary sewer with the treatment plant’s permission, collect and haul it or get an NPDES permit. |
| EPA lead Renovation, Repair and Painting Rule | Paid work that disturbs paint in housing and child-occupied facilities built before 1978 | The firm must be lead-safe certified, and EPA says pressure washing must be contained so no dust or debris, including in wash water, leaves the work area. |
| Workers’ comp in California | California employers, including those with one employee | Required by state law, per CSLB. CSLB licensees must file a certificate of coverage or a signed exemption stating they have no employees (Business and Professions Code 7125). |
| California D-38 classification | Contractors using water force to clean or prepare surfaces in California | CSLB defines the D-38 Sand and Water Blasting classification for this work. Ask CSLB whether your jobs require a license. |
| Commercial auto on business vehicles | Trucks and vans owned by the business | Insureon says most states require commercial auto for business-owned vehicles; state minimum limits apply. |
| Client certificates and bonds | Property managers, HOAs, retailers and other commercial clients | Clients often set limits, ask to be named as additional insured or require a janitorial bond, which Insureon notes may be needed to sign a contract. |

How to lower the cost
- Contain and recover wash water with berms, drain covers and a vacuum or pump, the methods Ohio EPA lists, so a runoff complaint never becomes a fine or claim.
- Test pressure, tip and mix on a hidden spot before washing siding, wood or paint, and photograph the property first.
- Keep gas-powered machines outside on every garage, parking deck and warehouse job, as NIOSH advises.
- Lock washers and pumps to the trailer, and do not leave the rig unattended in an open truck bed overnight.
- Choose limits and deductibles deliberately: Insureon says higher limits and lower deductibles raise premiums, so match limits to what clients actually require.
- Compare several quotes at renewal; Florin is an independent broker that compares options from several insurers.

Common questions
Pressure washing insurance: questions
Does general liability cover damage I cause to a customer’s house?
It is designed to. Progressive’s example is equipment that malfunctions and damages the paint on a customer’s house, which general liability can pay to repair, subject to your policy’s terms.
Can I use my personal pickup for pressure washing jobs?
Progressive notes personal auto typically does not cover business use. Insureon points to commercial auto for vehicles the business owns and hired and non-owned auto for personal or rented vehicles used for work.
Can I let wash water run into the street drain?
Generally not. Ohio EPA says storm drains usually lead straight to streams and wash water counts as industrial wastewater even with biodegradable soap, so letting it reach a storm sewer can violate the Clean Water Act.
Do I need lead certification to pressure wash an old house?
If the work disturbs paint on a home or child care facility built before 1978, EPA’s RRP Rule requires a lead-safe certified firm, including sole proprietorships. EPA also requires containment so no debris leaves the work area in the wash water.
Is workers’ comp required for a pressure washing business?
Insureon says state laws typically require it once you have employees, and California requires it even with one. A solo owner can often go without, though Insureon recommends it because health plans can deny work injury claims.
What is a janitorial bond and do pressure washers need one?
It reimburses a client if one of your employees steals from them, and some commercial clients require it before signing. Insureon reports a median of about $112 a year.
Can I run a gas pressure washer inside a parking garage or warehouse?
NIOSH warns against it: gasoline engines produce carbon monoxide that builds up quickly indoors. Keep the machine outside and bring the hose in.
