Pressure Washing Business Insurance

Of all the small service businesses, pressure washing has one of the most awkward insurance profiles. The work itself is low-skill and the equipment is cheap, but the damage you can do with high-pressure water and cleaning chemicals is meaningful. A bad afternoon can cost you a window, a deck stain, a customer's plants, or in rare cases the customer's roof. You need real coverage, but the policies sold to pressure washers are often loaded with exclusions that the operators don't notice until they file a claim.

This article walks through what most solo pressure washing operators actually carry, the coverage gaps that consistently bite people, and how to have a useful conversation with an insurance broker without getting upsold on coverage you don't need.

It's part of the Pressure Washing Business guide.

Talk to a licensed insurance broker before you buy a policy. What we describe below is the typical setup for a typical solo pressure washing operator using residential equipment in 2026. Your specific state, the kinds of jobs you actually take, whether you have employees, whether you handle hazardous chemicals (sodium hypochlorite, hydrofluoric acid for rust removal, etc.), and the types of property you work on can all change what coverage you genuinely need. A licensed broker can usually tell you what's appropriate for your specific situation in a 15-minute phone call, often for free, because they're paid by the insurer when you buy a policy. Use that resource. The wrong policy can be worse than no policy if you find out at claim time that you weren't covered for what you thought you were.

The four types of coverage worth understanding

For a pressure washing operator, there are four kinds of insurance that come up. Most solo operators carry the first one, sometimes the second, and rarely the others until they have employees or contracts that require them.

1. General liability insurance

This is the one almost every pressure washing operator needs. General liability covers third-party bodily injury and property damage caused by your work. If you crack a customer's window, kill their plants with cleaning solution, or chip the paint on their car with a high-pressure stream, this is the policy that pays the claim.

Typical coverage limits for solo operators:

• $1 million per occurrence
• $2 million aggregate per policy year

In our research, premiums for typical solo pressure washing operations usually run $400 to $1,200 per year, depending on state, coverage limits, the kinds of jobs you take (residential vs commercial), and the carrier. Operators we've talked to typically pay $600-$900 for a $1 million / $2 million policy.

What general liability usually covers:

• Property damage to a customer's house, car, fence, plants, or other property caused by your work
• Bodily injury to a customer or third party caused by your equipment, your slip-and-fall, or your operations
• Legal defense costs if you're sued, even if the suit is unfounded

What general liability usually doesn't cover:

• Damage to your own equipment (that's an inland marine policy)
• Damage to your work itself, called "your work" exclusion (if you blast a deck and the stain comes off because of poor prep, that may be excluded)
• Pollution or environmental claims (cleaning chemical runoff into a storm drain, etc.)
• Workers' compensation claims by employees
• Auto-related claims while driving
• Damage from equipment that wasn't properly maintained

The exclusions matter. We'll come back to them.

2. Commercial auto insurance

If you're using your personal pickup or van for the business, your personal auto policy may or may not cover you. Most personal policies have business-use exclusions, though the exact rules vary by insurer and state. If you're driving from job to job and you cause an accident, and the insurer determines you were "in the course of business," your personal policy may deny the claim.

The two paths to fix this:

• A business use endorsement added to your existing personal auto policy (usually adds $100-$300/year)
• A separate commercial auto policy ($800-$2,000/year for one vehicle, depending on coverage)

The endorsement is cheaper and works for many solo operators. The separate commercial policy is more appropriate if the vehicle is used primarily for business, has business signage on it, or is owned by the LLC rather than personally.

Call your existing personal auto insurer and describe what you'll actually be doing with the vehicle. Ask them in writing whether business use is covered, and what the specific exclusions are. Don't assume. The answer varies by insurer. Get the answer in writing so you have something to point to if there's ever a dispute.

3. Inland marine insurance (equipment coverage)

This covers your pressure washer, hoses, surface cleaners, and other equipment from theft, damage, or loss. If your trailer is broken into and your $3,000 hot water pressure washer is stolen, this is the policy that pays.

For a lean operator with $1,000-$2,000 of residential equipment, inland marine isn't usually worth the premium. For an operator with $5,000+ of commercial equipment (especially a hot water unit), it usually is. Premiums typically run 1.5-3% of the equipment's replacement value per year, so $5,000 of equipment costs $75-$150/year to insure.

This is also a good place to ask your broker about combining inland marine with general liability into a Business Owner's Policy (BOP), which can sometimes lower the combined premium.

4. Workers' compensation

You only need this if you have employees. Most states require it once you hire your first W-2 employee, even part-time. Some states require it even for sole proprietors in certain industries. Your state's Department of Labor or the equivalent will tell you the rules.

Workers' comp is expensive (typically 5-15% of payroll for a moderate-risk industry like pressure washing) and is one of the reasons many pressure washing operators stay solo for as long as they can.

The coverage gaps that bite operators

Here are the things that actually go wrong, in roughly the order we see them.

Gap 1: The "your work" exclusion

Standard general liability excludes damage to your own work. If you're hired to soft-wash a customer's house and the paint starts peeling because of incorrect cleaning solution dilution, the resulting damage to the house siding is your work product, and most policies will deny the claim.

The fix: ask the broker specifically about "your work" coverage and whether the policy includes "completed operations" coverage. Some carriers will offer broader coverage at a slightly higher premium. Whether it's worth it depends on the kinds of jobs you take.

Gap 2: Pollution exclusion

Almost every general liability policy has a pollution exclusion. If your cleaning chemicals run off into a storm drain, into a customer's koi pond, or onto a neighbor's property, the resulting environmental claim is excluded.

This matters more for commercial work than residential, because commercial properties often have specific stormwater compliance rules.¹ Some commercial contracts require you to carry pollution liability coverage as a condition of the contract.

The fix: if you're doing commercial work, ask about a "limited pollution liability" endorsement. It's usually cheap ($100-$300/year added to the GL policy).

Gap 3: Hot water and chemical-specific exclusions

Some general liability carriers exclude or limit coverage for hot water pressure washing or for the use of specific chemicals like sodium hypochlorite (bleach), hydrofluoric acid, or caustic strippers. The exclusion may be in the fine print rather than in the application questions.

The fix: tell the broker exactly what equipment you're using and exactly what chemicals you're working with. Get them to confirm in writing that the policy covers your specific operations.

Gap 4: The "additional insured" requirement on commercial contracts

If you ever bid on commercial work (HOAs, retail centers, office complexes, restaurant chains), the contract will almost always require you to add the property owner as an "additional insured" on your general liability policy. Most policies allow this for free or for a small fee per certificate. Some don't.

The fix: ask the broker whether the policy supports adding additional insureds at no charge, and how the certificate request process works. Some carriers have an online portal that issues the certificate in 5 minutes; others take 2 days and charge a fee.

What we'd actually buy

If we were starting tomorrow as a solo residential pressure washing operator with $4,000-$5,000 in equipment, here's what we'd carry in year one:

• General liability: $1M per occurrence / $2M aggregate. Approximately $500-$800/year. Confirm the broker that "your work" damage and pollution endorsements are available if you ever want them.
• Commercial auto endorsement added to personal auto, since the truck is also our personal vehicle. About $150-$250/year added to existing premium.
• Inland marine: Skip it in year one if equipment is under $2,000. Add it in year two when we upgrade to a commercial unit.
• Workers' comp: Skip it. Solo operator, no employees.

Total year-one insurance budget: $650-$1,050.

In year two, after adding a $3,000 hot water unit:

• Same general liability ($500-$800/year)
• Same commercial auto endorsement ($150-$250/year)
• Add inland marine for the equipment ($75-$120/year)
• Still no workers' comp

Year two total: $725-$1,170.

The premium grows slowly compared to the revenue. In a typical solo operator's $40K-$70K annual revenue, insurance is 1-3% of revenue. That's a small enough line item that you should not be cutting corners on it.

Questions to ask the broker

If you call a broker tomorrow, here are the questions to actually ask. Bring this list to the call.

1. What's the per-occurrence limit and the aggregate limit?
2. Does this policy cover residential and commercial pressure washing, or only one?
3. Is the "your work" exclusion in this policy, and is broader coverage available?
4. What chemicals are excluded? (Specifically ask about sodium hypochlorite if you'll be soft-washing.)
5. Is hot water pressure washing covered or excluded?
6. Is there a pollution exclusion, and is a limited pollution endorsement available?
7. Can I add additional insureds at no extra cost? How is the certificate requested?
8. What's not covered? (Make them go through the major exclusions verbally.)
9. What's the deductible? Can it be lowered?
10. How are claims handled? Is there a 24-hour claims line, or do I email a form?

If the broker can't answer most of these without hesitation, find a different broker. The good ones know this stuff cold.

Where to get quotes

Most solo operators we know start with three quotes from these channels:

• Online quote tools like Thimble, Next Insurance, Hiscox, Insureon. Fast, no phone call, suitable for simple solo operations.
• Local independent insurance agents who specialize in commercial/business policies. Slower, but they shop multiple carriers and can sometimes find better coverage at the same price.
• Industry-specific insurers like RPS Pro Insurance or specialized cleaning industry brokers. Usually the most niche-aware option.

Get quotes from at least two channels. The price spread between providers can be 2x for the same coverage, and the coverage details vary even more.
