Window cleaning has among the highest profit margins of any home service โ€” labor is the main cost (no materials to speak of) and most homeowners avoid it completely. A solo window cleaner charging $100โ€“$250/home cleans 4โ€“6 homes per day.

Startup Kit ($200โ€“$500)

Squeegees (various sizes): $40โ€“$80. Extension poles: $30โ€“$60. Cleaning solution (Dawn + water is fine): $10/month. Microfiber cloths: $20. Ladders (may already own): $80โ€“$200. Bucket and scrubbers: $30. Professional window cleaning kit from Amazon: $80โ€“$150 (contains most of the above).

Commercial vs. Residential

Residential: easier to get, lower per-job income ($100โ€“$300), friendly clients. Commercial (storefronts, office buildings): recurring monthly contracts, $150โ€“$600/building, more reliable income. Target commercial buildings once you have a vehicle and professional equipment.
