Pressure washing looks like a low-risk trade from the outside: a truck, a trailer, a machine, and some water. But the claims that cross our desks at Shurr Insurance are rarely small. We’ve seen everything from stripped cedar decks and dead HOA landscaping from bleach runoff to fall injuries and stolen trailers loaded with $18,000 worth of gear.
Here’s a clear breakdown of what pressure washing and soft wash contractors actually need, where the hidden policy traps are, and how to protect your hard-earned business.
Most pressure washing businesses need five core coverages: general liability (third-party property damage and injury), inland marine / contractor's equipment (your machines, trailers, and tools), commercial auto (trucks and towing), workers' compensation (employee injuries), and contractors pollution liability (chemical discharge and runoff). Contractors bidding commercial, municipal, or property-management work usually add a commercial umbrella to meet contract limits.
Here is why each coverage matters—and where standard policies leave you exposed.
General liability (GL) is the policy every customer, property manager, and general contractor asks to see. It responds when you damage someone else’s property or injure a third party—like overspray that ruins a parked car's finish or a slip on a wet walkway.
However, two major exclusions inside a standard commercial general liability form catch pressure washers off guard constantly:
Soft washing is chemical work. Whether you're running sodium hypochlorite, degreasers, rust removers, or brighteners, your tank contains materials that insurance companies treat as pollutants. Standard GL policies feature strict pollution exclusions.
Without specific pollution coverage, you are exposed to:
Contractors Pollution Liability (CPL) is a standalone policy—or a targeted endorsement—that covers third-party injuries, property damage, and environmental cleanup.
Pro Tip: If you use a wash water reclamation system, let us know! It can significantly reduce your CPL premiums with our carriers.
This is the second biggest pitfall we see with local contractors.
To protect your gear on the road and on the job, you need Inland Marine / Contractor's Equipment Coverage.
Always check with us to ensure your policy pays out on Replacement Cost rather than Actual Cash Value (depreciated value), and that your per-item limit covers your most expensive rig.
If your truck is titled to your business, wrapped with your logo, or towing a commercial rig, personal auto insurance won't cut it—a claim will likely be denied.
Pressure washing carries real physical risks: high-pressure injection injuries, roof falls, severe chemical burns, electrocution from outdoor power sources, and heat exhaustion.
Indiana law requires employers to carry Workers' Compensation if they have employees. If you operate as a sole proprietor or single-member LLC, you may legally opt out—but many commercial clients will still demand proof of coverage before letting you bid.
If you hire 1099 subcontractors, you must collect a valid Certificate of Insurance (COI) from them before they touch a job site. If you don't, your insurance auditor will classify those subcontractors as employees and hand you an unexpected audit bill for thousands of dollars at the end of the year.
| Coverage | When You Need It |
| Commercial Umbrella | Required by property managers and national accounts needing $2M–$5M in total limits. |
| Business Owner’s Policy (BOP) | When you buy or lease a dedicated shop, office, or storage yard. |
| Business Income Extension | Keeps your income flowing if a fire or major disaster shuts down your operations. |
| License & Permit Bonds | Required for municipal, school, or public bid contracts in Indiana. |
| Employment Practices Liability (EPLI) | Protects your business against employee lawsuits as you build a larger team. |
Premiums in the pressure washing industry are primarily rated on your gross receipts and payroll. Underwriters also look at:
Because power washing in Northwest Indiana is seasonal, talk to us about flexible reporting options so you aren't paying peak-season rates during slow winter months.
Do I need insurance to start a pressure washing business in Indiana?
While Indiana state law doesn't strictly mandate general liability just to open your doors, you practically need it to work. Commercial clients, HOAs, and homeowners will demand a Certificate of Insurance (COI) before hiring you. Workers' comp is mandatory as soon as you hire your first employee.
Does general liability cover damage to the surface I’m cleaning?
Not by default. Standard GL forms exclude damage to "that particular part" of the property you are servicing. You need specific buy-back endorsements or Errors & Omissions coverage for stripped wood, etched concrete, or damaged siding.
Is bleach overspray or chemical runoff covered?
No. Standard GL forms exclude pollution. You need a Contractors Pollution Liability policy (or endorsement) to cover chemical damage to landscaping or storm sewer contamination.
Is my equipment covered if my trailer is stolen off a job site?
Only if you carry an Inland Marine / Contractor's Equipment policy. Auto, home, and standard business property policies exclude off-premises equipment theft.
The cheapest policy isn't worth much if a single ruined deck or chemical runoff claim gets denied because of hidden exclusions.
