Coverage Every Pressure Washing Business Needs

🛡️

General Liability — $1M minimum

Required

Covers property damage (broken windows, stripped paint, etched surfaces, chemical overspray on vehicles) and bodily injury (clients slipping on wet surfaces). Commercial clients, HOAs, property managers, and apartment complexes require proof of GL before any pressure washing work begins.

🔧

Inland Marine (Equipment)

Highly Recommended

Covers your pressure washers, hoses, surface cleaners, chemical tanks, and trailers at job sites and in your vehicle. Commercial pressure washers cost $2,000–$15,000. Equipment stolen from your vehicle overnight is an inland marine claim — not covered by commercial property (fixed location) or auto.

🚚

Commercial Auto

Required

If you drive to job sites in a work vehicle, you need commercial auto. Personal auto policies exclude business use. If you haul a pressure washer trailer and are in an accident, commercial auto covers the vehicle and trailer liability.

👷

Workers' Compensation

Required with employees

Required in most states for any employer. Pressure washing employees face slip hazards, chemical exposure, and heat-related illness. WC covers medical treatment and lost wages for work injuries.

☣️

Pollution Liability

Recommended for commercial ops

Covers environmental liability from chemical cleaning runoff entering storm drains. Required by some municipalities for commercial pressure washing contractors. Essential for fleet washing, parking structure cleaning, and restaurant exterior operations.

Pressure Washing Insurance FAQ

Frequently Asked Questions

What insurance does a pressure washing business need?+
Pressure washing businesses need: (1) General Liability — covers property damage (window cracks, surface etching, paint strip) and bodily injury (client slipping on wet surfaces near your work area). This is non-negotiable — commercial clients and HOAs require proof of GL before you start. (2) Inland Marine — covers your pressure washers, hoses, and equipment at job sites and in your vehicle. (3) Commercial Auto — required if you use a work vehicle. (4) Workers' Comp — required if you have employees, covers slip injuries, chemical burns, and equipment-related injuries.
How much does pressure washing insurance cost in 2026?+
Solo pressure washing operator (residential only): $55–$95/month for GL + basic equipment coverage. Add commercial auto for $80–$150/month. Small operation with 2–3 employees and trucks: $250–$500/month (GL + WC + equipment + vehicles). Total for a fully insured solo operator: $135–$245/month. Companies doing commercial pressure washing (parking structures, fleets, restaurants) pay more due to pollution liability exposure and higher revenue.
What is the most common pressure washing insurance claim?+
Window damage is the most frequent pressure washing claim. High-pressure water applied at the wrong angle or PSI can crack aged window glass, force water behind window frames, and damage weatherstripping seals. Surface damage is second most common — wrong pressure or nozzle angle on painted wood, EIFS stucco, or aged concrete can strip paint and etch surfaces. Both are GL property damage claims. Pre-job surface photography and client walk-throughs to document pre-existing damage are your best loss prevention tools.
Do I need pollution liability for pressure washing?+
Possibly — it depends on your services. If you do parking lot cleaning, fleet washing, restaurant exterior cleaning, or any application involving concentrated chemical cleaners (sodium hypochlorite, degreasers, acid-based cleaners), runoff entering storm drains can create pollution liability exposure. Standard GL policies typically include a pollution exclusion. If you work commercially or use strong cleaning chemicals, ask about a pollution liability endorsement or standalone policy. Some municipalities require it for contractors working near storm drain systems.
Does GL cover damage to a client's vehicle from overspray?+
Yes — chemical overspray or high-pressure water hitting a client's or neighbor's vehicle is a GL property damage claim. This is particularly relevant for exterior house washing where bleach-based cleaning solutions can run onto vehicles in driveways. Best practice: cover or move vehicles before applying any chemical cleaning solution. If damage occurs, document it immediately and contact your carrier — do not offer out-of-pocket settlements without carrier involvement.
Do pressure washing companies need a business license?+
Most states do not require a specialty license for pressure washing. However, many municipalities require a general business license to operate commercially. Some cities require a separate license or permit for commercial contractors working within city limits. If you apply any chemical cleaning agents (pesticides, herbicides, algaecides), verify whether a pesticide applicator license is required in your state — some states classify bleach-based algae treatments as pesticide application requiring a license.
