Window cleaning insurance: what every window washing business needs

Window cleaning combines height work, water, squeegees, and client property — creating real liability exposure at every job. Here's what window cleaning businesses need to operate covered and professional.

6 most common window cleaning insurance claims

1. Squeegee or pressure cracks a window — $200–$8,000 replacement depending on type
2. Water infiltration from window seal damaged during cleaning — $3,000–$15,000 interior damage
3. Ladder placed against siding or trim causes damage — $800–$3,000
4. Client trips on hoses or equipment on property — $5,000–$18,000 medical claim
5. Cleaning solution damages painted or treated surfaces around windows — $1,000–$4,000
6. Worker falls from ladder — workers' comp claim, $20,000–$150,000+

Coverage stack for window cleaning businesses

High-rise vs. low-rise: what changes

Standard GL policies like Thimble cover ground-level and low-rise window cleaning. Work above 3–4 stories typically requires specialty coverage and OSHA rope access or swing stage certifications. If you plan to do commercial high-rise work, disclose the building heights to your insurer — doing high-rise work on a low-rise policy creates uninsured exposure.

5 practices that reduce window cleaning claims

1. Inspect windows for existing cracks before cleaning and document with photos
2. Test cleaning solutions on an inconspicuous area before applying to frames
3. Use proper ladder standoffs to prevent contact with frames and sills
4. Protect landscaping and AC units from runoff before starting
5. Never work on windows when temperature is below 40°F — solution can freeze and cause thermal shock
