Residential window cleaning costs $10 to $15 per window or $4 to $8 per pane on average. A professional window washer charges $151 to $366 to clean an average-sized house, which is $40 to $75 per hour.

Commercial window cleaning prices are $0.50 to $2.50 per square foot or $5 to $15 per window for storefront or building windows. A 1,000 to 5,000 SF building costs $250 to $450 per month for one cleaning per week.

Professional window cleaners typically use tools such as a window mop, window razor, squeegees, sponges, microfiber cloths, ladder, pole, and cleaning solution or soap.

Window washers do not expect a tip. However, if they go above and beyond or spend more time than expected, a $5 to $20 tip is appreciated.

1. Professional window cleaners start by removing and cleaning all the screens with a wet mop.
2. Cleaners then wash the inside and outside of the windows with a cleaning formula to remove stains and debris.
3. Any remaining debris are safely scraped with a razor blade and brushed clean. The glass is then squeegeed clean, leaving them free of dirt and streaks.
4. Lastly, they wipe the window sills, tracks, and edges clean, replace the screens, and alert you of any broken seals, trim, or scratches.

To find window cleaning companies, do the following:

• Start your search on websites like HomeGuide and Google.
