Most window cleaning companies you hire will carry basic liability insurance, but the gaps in coverage can leave you liable for damage or accidents—especially on larger homes or commercial properties. Understanding what's covered, what's not, and when you need extra protection is critical before signing a contract. Here's what every homeowner and building manager should know.
Why Standard Window Cleaning Insurance Isn't Always Enough
Window cleaning involves working at heights, handling glass, and accessing areas prone to accidental damage. A reputable cleaning company typically carries general liability insurance (usually $1–2 million in coverage), which covers bodily injury and property damage caused by their negligence. However, this doesn't automatically protect you from every scenario.
Consider a common situation: a cleaner's ladder scratches your vinyl siding, or their equipment damages your gutter. Most policies have exclusions for certain types of damage, deductibles ($500–$2,500 is standard), or caps on what they'll pay for specific incidents. If the cleaner causes damage valued at $5,000, but their policy only covers up to $3,000, you're out the difference.
What Standard Policies Actually Cover
A typical window cleaning company's general liability policy covers:
- Bodily injury if a cleaner falls or gets injured on your property
- Third-party property damage (e.g., damaging a neighbor's fence during work)
- Accidents directly caused by the cleaner's negligence
- Some water damage from cleaning runoff (terms vary)
What they often don't cover:
- Damage to your home's interior if water enters through windows
- Pre-existing structural issues that cleaning work exacerbates
- Damage to landscaping or outdoor décor
- Injuries to the homeowner or guests during the service
- High-value custom or stained glass
- Damage claims that fall below their deductible
When You Should Request Extra Coverage
For typical single-story residential cleaning (a few hundred dollars per service), standard liability is usually sufficient. However, consider additional coverage or stronger terms if:
Your home has high-value windows or special glass. Custom stained glass, restoration windows, or specialty glazing can cost $1,000–$5,000+ per pane to replace. Ask your window cleaner if they can add a rider for high-value windows or confirm their policy covers accidental breakage at replacement cost.
You have a multi-story home or commercial building. Larger jobs involve more workers, higher fall risk, and greater exposure. Request proof of coverage of at least $2 million and ask about workers' compensation insurance (required in most states).
Your property has unique vulnerabilities. If your home sits on a hillside, has recently plastered walls, or features expensive siding, damage risk is higher. Discuss these specifics with the cleaner and your homeowner's insurance agent before booking.
You're having interior or hard-to-reach windows cleaned. Interior work increases the risk of water damage to furniture, electronics, or flooring. Confirm the cleaner carries equipment damage and water damage coverage before proceeding.
Steps to Take Before Hiring
- Request a Certificate of Insurance. Ask the window cleaning company to provide a current COI naming you as "additional insured." This document proves they carry active coverage and shows the policy limits and deductible.
- Call your homeowner's insurance agent. Discuss the planned service and ask whether your policy covers damage caused by a contractor. Some policies have gaps; knowing this beforehand prevents surprises.
- Get the job in writing. Include what areas will be cleaned, what cleaning solution will be used, and who's responsible for damage to specific items (skylights, solar panels, etc.).
- Ask about workers' comp. If the company has employees, they should carry workers' compensation. This protects you from liability if a worker is injured on your property.
- Compare quotes through a trusted platform. Services like Mercoly help you find and compare window cleaning providers in your area, read customer reviews, and verify insurance details—saving time and reducing risk.
The Cost-Benefit Reality
Adding extra coverage through a rider to your homeowner's policy typically costs $50–$150 per year and covers contractor-related damage up to your chosen limit. For homes with valuable windows or multi-story layouts, this is inexpensive peace of mind. For basic single-story window cleaning on standard glass, your contractor's standard liability policy is usually adequate if they're insured and reputable.
Frequently Asked Questions
Q: Can I ask a window cleaner to add me to their insurance policy? No—you can only be named as "additional insured" on their policy, which means you're protected if their coverage applies, but you can't modify their coverage limits. Request a current Certificate of Insurance instead.
Q: What should I do if a window cleaner damages my property? Document the damage with photos, notify the cleaning company immediately, and file a claim with their insurance within 30 days. If they're uninsured, your homeowner's policy may cover it (subject to your deductible), or you may need to pursue small claims court.
Q: Are window cleaners required to have insurance? Insurance requirements vary by state and locality. Most professional companies carry it, but sole proprietors sometimes don't. Always verify before hiring.
