Pressure washing equipment runs at 3,000+ PSI. At that pressure, a wrong move can shatter a window, strip paint, or injure a bystander. That's why insurance isn't optional — it's the thing that keeps one bad day from ending your business. Here's exactly what coverage you need and what it costs in 2026.

The Quick Answer: What Does Pressure Washing Insurance Cost?

For a solo operator, expect to pay:

General Liability: $400 - $1,500/year (average ~$895/year)
Workers' Compensation: $2,000 - $6,000/year if you have employees
Commercial Auto: $1,200 - $3,000/year per vehicle
Equipment/Tools Coverage: $200 - $600/year

A solo operator running one truck typically pays $840 - $1,200/year total for GL plus commercial auto. Add employees and that number rises significantly due to workers' comp.

General Liability Insurance

General liability (GL) is the foundation. It covers property damage and bodily injury caused by your work. If your pressure washer breaks a client's window, dents their car, or knocks someone off a ladder, GL covers the claim.

Average cost: $75/month, or about $895/year for a solo operator with under $100k in annual revenue. Rates climb as revenue grows and as you add services like roof washing, which carries higher liability.

Coverage amount: Most residential clients don't specify a minimum. Commercial clients — HOAs, property managers, municipalities — typically require $1M per occurrence and $2M aggregate. Make sure your policy hits those numbers before bidding commercial work.

What it does NOT cover: Damage to your own equipment, injuries to your employees (that's workers' comp), and your business vehicles (that's commercial auto).

Workers' Compensation Insurance

If you have any employees — even part-time or seasonal — you almost certainly need workers' comp by law. It covers medical expenses and lost wages if an employee gets injured on the job.

Average cost: $133/month ($1,600/year) for a small crew. Rates vary significantly by state. New York averages $98/month per worker; states with less regulation run lower.

Solo operators: If it's just you with no employees, you can often waive workers' comp. Check your state's rules — some states require it even for single-person LLCs.

The risk of skipping it: One employee falling off a ladder during a roof wash could mean $50,000+ in medical bills. Workers' comp pays that. Without it, you pay it — or go out of business.

Commercial Auto Insurance

Your personal auto policy will not cover your truck if you're using it for business. If you get into an accident driving to a job, a personal policy can deny the claim entirely.

Average cost: $1,200 - $3,000/year depending on vehicle type, your driving record, the state, and how far you drive. A pickup truck used for local residential work is on the lower end. A truck towing a pressure washing trailer makes more trips and carries more risk — expect higher rates.

What to cover: The truck, any trailers, and the equipment in transit. Make sure your policy covers equipment theft from the vehicle — tools and pressure washers get stolen.

Equipment and Tools Coverage

Your commercial auto policy covers the equipment while in transit, but not while you're working with it. Equipment breakdown coverage and inland marine coverage protect your pressure washer, surface cleaners, hoses, and other gear against theft, vandalism, and accidental damage.

Average cost: $200 - $600/year. If you're running a $4,000 commercial-grade pressure washer, this is worth it. Replacing equipment out of pocket is the kind of hit that derails a new business.

What's Required vs. Recommended

General Liability — Required. No serious residential customer will hire an uninsured pressure washer. Commercial clients will ask for your certificate of insurance before you start.
Commercial Auto — Required. Legally required in every state if you use a vehicle for business purposes.
Workers' Comp — Required if you have employees. Most states mandate it. Check your state's threshold (some require it above 1-2 employees).
Equipment Coverage — Recommended. Not legally required, but important if your equipment represents a significant investment.

How to Get the Best Rate

Insurance rates vary by carrier. Get at least 3 quotes before choosing. Some of the most competitive options for pressure washing businesses in 2026:

NEXT Insurance — Fast online quotes, popular with small contractors
Insureon — Compares multiple carriers at once
Progressive Commercial — Good rates on commercial auto
Insurance Canopy — Specializes in cleaning businesses

Bundling GL and commercial auto with the same carrier typically saves 15-20% compared to separate policies.

A Note on Roof Washing

Standard pressure washing GL policies may exclude or limit coverage for roof work. If you offer soft washing or roof cleaning, ask your carrier specifically whether that's covered. Some require a separate endorsement or a higher premium for elevated work. Find out before you take a roof job, not after a claim gets denied.

The Bottom Line

A solo operator should budget $840 - $1,500/year for GL plus commercial auto. That's $70-125/month. It's a real cost, but it's also the price of operating professionally. When a customer asks "are you insured?" and you can say yes and hand them your certificate, you've already separated yourself from half the competition.
