The insurance you need for pressure washing isn't one-size-fits-all. What works for residential jobs will get you turned away from commercial contracts -- and the gap between the two markets is bigger than most contractors expect.

The Quick Answer

Here's how insurance requirements differ by market:

Residential GL coverage: $1M per occurrence / $2M aggregate
Commercial GL coverage: $1-$2M required (often $2M minimum for contracts)
Specialty commercial (high-rise, hospitals): $2-$5M
Average GL cost -- residential focus: $70-$75/month ($840-$900/year)
Commercial auto insurance: ~$170/month average
Workers' comp: Required in most states once you hire your first employee

If you do both residential and commercial work, one policy can cover both -- but you need to tell your agent what's actually in scope.

Residential Pressure Washing Insurance

For residential work, basic general liability covers most situations. Homeowners rarely ask to see a certificate of insurance before you start -- but that doesn't mean you can skip it.

General Liability

A $1M/$2M general liability policy covers property damage and bodily injury caused by your work. At 3,000+ PSI you can shatter windows, strip paint, and damage siding. GL is what pays when that happens.

Average cost for a solo residential operator: $75/month through providers like NEXT Insurance or Insureon.

What Residential Work Doesn't Usually Require

Homeowners rarely ask for:

Certificates of insurance (COI) before you arrive
Additional insured endorsements
Umbrella policies
Completed operations coverage

That's the upside of residential. The downside is that most homeowner jobs are one-time, and you're constantly chasing new leads to fill the calendar.

Commercial Pressure Washing Insurance

The moment you knock on a property manager's door, the requirements change. Commercial clients sign contracts. Contracts have insurance clauses. Those clauses are non-negotiable.

General Liability: $2M Minimum

Most commercial clients require $2M per occurrence, not $1M. Some larger properties -- shopping centers, medical facilities, HOAs -- want $2M aggregate across the full policy year. If you're quoting commercial work on a $1M/$1M policy, you'll be turned down at the contract stage.

The cost to upgrade from $1M to $2M coverage typically adds $10-$30/month to your GL premium -- well worth it for access to recurring commercial contracts.

Additional Insured Endorsements

This is the part most new contractors don't expect. Commercial clients routinely want to be named as additional insureds on your policy. That means if a claim arises from your work, your insurer also defends them.

Adding an additional insured typically costs $25-$75 per client per year. If you're managing 10 commercial accounts, budget $250-$750 annually just for endorsements. Build it into your overhead.

Workers' Compensation

Workers' comp isn't just a crew concern -- many commercial contracts require it even for solo operators. Property managers need to confirm their building isn't liable if you get hurt on-site.

Most states require workers' comp once you hire your first employee. New York requires it with just one part-time worker. Florida allows up to four employees before requiring coverage. Know your state's threshold before you hire.

Commercial Auto Insurance

If your truck or trailer is used for business, personal auto coverage doesn't protect you -- and won't pay out in a work-related accident. Commercial auto insurance averages $170/month for a pressure washing operation with a work vehicle and trailer.

The Real Cost Difference

Here's how annual insurance spend breaks down at each level:

Residential solo operator (GL only): $840-$1,080/year
Residential + commercial, no employees (GL + commercial auto): $2,400-$4,200/year
Full commercial with employees (GL + commercial auto + workers' comp): $5,000-$15,000+/year

The jump looks steep. But a single quarterly commercial contract worth $3,000-$8,000 covers most or all of your annual insurance cost. The math works if you're actually doing commercial work.

How to Get the Right Policy

Don't just buy the cheapest GL policy and assume you're covered. When you talk to your broker, tell them:

What surfaces you clean. Roofs and high-rise work trigger different underwriting than driveways.
Whether you use chemicals. Some GL policies exclude chemical damage claims by default.
Commercial or residential. Specify both if you do both -- coverage gaps often appear at the commercial/residential boundary.
Your annual revenue. GL premiums scale with revenue for most providers.
Number of employees. Even one part-time helper changes your workers' comp requirement in most states.

Insurance as a Growth Tool

Here's the thing most contractors miss: proper insurance isn't just protection -- it's a sales tool. When you hand a property manager a COI showing $2M GL, additional insured endorsement capability, and commercial auto coverage, you're signaling professionalism. Competitors who show up without it lose the contract before the pricing conversation even starts.

Getting bonded and properly insured is one of the fastest ways to move from residential one-timers to commercial recurring contracts. The paperwork takes a few hours. The contracts it unlocks can be worth $30,000-$80,000 per year from a single client.

Bottom Line

Residential pressure washing needs basic GL. Commercial contracts need $2M GL, additional insured capability, commercial auto, and often workers' comp. The extra $1,500-$3,000 per year unlocks access to contracts that pay 5-10x more per job and renew annually.
