A window cleaner loses their footing on a ladder and damages your gutters—who pays? Your hired contractor's truck sideswiped your car during a job—is it on you or them? Without proper insurance, these scenarios become your financial problem, not theirs.
Why Window Cleaner Insurance Protects Your Wallet
Window cleaning involves heights, ladders, and access to your home's exterior. Accidents happen even with experienced professionals. Insurance protects you from liability if someone gets hurt on your property or damage occurs to your home during the service.
When a window cleaner is uninsured, you're essentially absorbing all risk. If a worker falls and needs emergency care, you could face a lawsuit. If they damage your siding, gutters, or roof while reaching upper windows, you're responsible for repairs—often costing $500 to $3,000+.
What Types of Insurance Matter
General Liability Insurance is the baseline. This covers property damage (broken siding, damaged trim) and third-party bodily injury claims. Most legitimate window cleaners carry this; ask for a certificate of insurance naming you as an additional insured.
Workers' Compensation Insurance is required by law in most states if the cleaner employs staff. This protects you from being sued if a worker is injured on the job. If someone is working solo, verify they're either a registered business or carry workers' comp anyway.
Commercial Auto Liability matters if the cleaner uses their vehicle to transport equipment or materials. A ladder falling off their truck into your fence is covered here—not general liability alone.
How to Verify Coverage
Don't just take someone's word for it. Request a Certificate of Insurance before the work begins. This document shows:
- The insurance company name
- Policy number and expiration date
- Coverage limits (typically $1–2 million for general liability in window cleaning)
- Your address listed as an additional insured
Call the insurance company yourself if you're uncertain. Verification takes 5 minutes and prevents major headaches. Many window cleaners can email certificates same-day.
What Coverage Limits Are Reasonable
Standard general liability for window cleaning ranges from $1 million to $2 million in coverage. For residential work, $1 million is adequate protection for most homes. If you have high-value property, ask about umbrella policies that provide additional coverage beyond standard limits.
Some customers assume higher limits mean better quality—they don't. A $500,000 limit is still legitimate; it just means the cleaner works on smaller jobs or newer properties. What matters is that some insurance exists.
Red Flags to Watch
- The cleaner has no insurance certificate at all
- The policy expired months ago (ask for renewal proof)
- Their coverage limits are under $500,000 (unusually low)
- They claim insurance is "too expensive" and offer a discount for cash-only work
- They're reluctant to provide documentation without a lengthy explanation
Any of these warrant finding someone else. Professional window cleaners expect this question and answer it immediately.
Comparing Window Cleaners: Beyond Insurance
Insurance is necessary but not sufficient. When comparing providers, also check:
- Service scope: Do they clean frames, sills, interior, screens, and gutters, or just glass?
- Pricing: Residential window cleaning typically runs $150–$400 per visit depending on home size and window count.
- Frequency options: Most offer one-time, monthly, quarterly, or seasonal service.
- Guarantees: Do they guarantee streak-free results? What's their response time for touch-ups?
Mercoly lets you compare trusted window cleaning providers in your area, check their insurance status, and read reviews in one place—making it easy to find a cleaner who's both insured and reliable.
When You Need Insurance Most
- Multi-story homes with second- or third-floor windows
- Historic homes with fragile frames or trim
- Properties with expensive landscaping near gutters and siding
- Homes with skylights or solar panels requiring careful cleaning
In these scenarios, an insured professional is non-negotiable.
Frequently Asked Questions
Q: What if the window cleaner has insurance but the certificate lists a previous address for my house? A: Ask them to request an updated certificate from their insurer naming your current address. This takes 1–2 business days and ensures coverage applies to your specific property.
Q: Does my homeowner's insurance cover damage caused by a contractor I hired? A: Usually no—your policy covers accidents on your property that you cause, not those caused by someone you hired. That's why their insurance matters.
Q: How much should a window cleaner's insurance cost them? A: General liability runs $300–$600 annually for small window cleaning operations, depending on the insurer and service area.
