Pressure washing and soft washing might seem straightforward—spray, clean, done—but hiring the wrong contractor can leave you with damaged siding, stripped paint, or worse, flooded foundations. Insurance and liability gaps are where most homeowners get burned, often discovering gaps only after something goes wrong. Before you hand over your keys or deposit, here's exactly what to verify.
Why Insurance Matters More Than You Think
A pressure washer operating at 3,000–4,000 PSI can strip paint, crack wood, shatter windows, and damage roofing shingles if mishandled. If a contractor causes damage to your property and has no liability coverage, you're stuck paying for repairs yourself. Many inexperienced operators skip proper insurance altogether to undercut their competition—a red flag that should disqualify them instantly.
The Two Insurance Types You Need to See
General Liability Insurance covers property damage and bodily injury. If a contractor's hose hits your gutter and causes water damage to your fascia, or if they slip on your driveway and break an ankle, this is what protects you both. Ask for a minimum of $1 million in coverage; most reputable pressure washing companies carry this as standard. Request a Certificate of Insurance (COI) naming you as an "additional insured"—this ensures the coverage extends to protect you on your property.
Workers' Compensation Insurance is legally required in most states if the contractor has employees. If they work solo, they may carry a "sole proprietor" policy instead. This covers medical bills and lost wages if a crew member gets injured on your job. Never hire a multi-person team without verifying this coverage exists.
What to Ask For—Specifically
Don't just take their word for it. Request these documents before signing anything:
- Certificate of Insurance with current expiration date (should be dated within the last 30 days)
- Proof of business licensing in your state
- A written estimate that includes the scope of work, pressure levels (PSI), cleaning methods (pressure vs. soft wash), and areas being treated
- References from 3–5 recent residential jobs (not just commercial)
- A written liability waiver for YOUR signature, acknowledging any inherent risks
Red Flags to Walk Away
A contractor who gets defensive or vague when you ask for proof of insurance is hiding something. If they claim "I'm covered under my homeowner's insurance," that's false—homeowner policies explicitly exclude business use. Anyone quoting work without seeing the job in person, or offering a price drastically lower than competitors (typically $200–500 for average residential exterior cleaning), is cutting corners somewhere.
Also watch for vague descriptions like "we'll clean it." Legitimate contractors specify whether they're using pressure washing (ideal for concrete, some siding) or soft washing (safer for roofing, delicate surfaces, stucco). This distinction directly affects risk.
Verify Licensing and Bonding
Many states require pressure washing contractors to be licensed. Check your state's licensing board or the Better Business Bureau to confirm they're registered and dispute-free. Some areas also require bonding—a financial guarantee that they'll complete the job as promised. While not always mandatory, it's a sign of professionalism.
The Contract and Insurance Timeline
Once you've confirmed insurance, get everything in writing. Your contract should state:
- Start and end dates
- Weather contingencies (rain stops the job)
- What surfaces will and won't be washed
- Pressure levels and chemicals used (if any)
- Insurance coverage details and the additional insured clause
- A clear cancellation and refund policy
Never pay the full amount upfront. Standard terms are 50% deposit, 50% upon completion. If a contractor demands full payment in advance, move on.
Making Comparisons Easier
Finding and vetting multiple contractors can be tedious. Platforms like Mercoly let you compare several trusted pressure and soft washing providers in your area at once, review their credentials, and see real customer feedback side-by-side—saving you time and reducing the risk of hiring an uninsured operation.
Frequently Asked Questions
Q: What's the difference between pressure washing and soft washing, and does it affect insurance claims? Pressure washing uses high-pressure water jets (2,500+ PSI) for concrete and driveways; soft washing uses low pressure with cleaning solutions for delicate surfaces like roofing and vinyl siding. A contractor doing soft wash work on a roof that gets damaged via pressure washing may not be covered by insurance if it violates their policy limits or methodology.
Q: If a contractor causes damage, will my homeowner's insurance cover it? Not typically—that's why the contractor's liability insurance is critical. Your homeowner's policy covers sudden accidents, but won't cover negligence or damage caused by a third party's work.
Q: How much should I expect to pay for residential pressure washing? A typical house exterior costs $250–$500 depending on size and condition; driveways run $150–$300. Suspiciously low quotes often indicate poor insurance coverage or inexperience.
