Window Cleaning Formula: Base Time = 5 minutes per window Adjusted Time = Base Time × Window Type × Cleaning Type × Condition × Floor Multiplier Screen Time = 3 minutes per window (if applicable) Total Time = (Adjusted Time + Screen Time) × Window Count + 30 min setup Total Cost = (Total Time / 60) × Hourly Rate Cost Per Window = Total Cost / Window Count Floor Multiplier = 1 + ((Floors - 1) × 0.15)
Example: Windows = 20 Type = Standard Windows Floors = 2 Cleaning = Inside & Outside Condition = Medium Screens = Yes Hourly Rate = $50/hour Base Time = 5 min Adjusted = 5 × 1 × 2 × 1.3 × 1.15 = 14.95 min/window With Screens = 14.95 + 3 = 17.95 min/window Total Work Time = 17.95 × 20 = 359 minutes (5h 59m) With Setup = 359 + 30 = 389 minutes (6h 29m) Total Cost = 6.48 hours × $50 = $324 Cost Per Window = $324 / 20 = $16.20

How much does professional window cleaning cost?

How long does it take to clean windows?

Professional window cleaners can clean a standard window (inside and outside) in 5-10 minutes. A typical 2-story house with 20 windows takes 2-4 hours including setup, screens, and frames.

Should I clean windows inside and outside?

For best results, clean both inside and outside. Outside windows get dirty from weather and pollution, while inside windows accumulate dust and fingerprints. Cleaning both sides ensures crystal-clear views.

Most homes benefit from professional window cleaning 2-4 times per year (every 3-6 months). Commercial buildings may need monthly cleaning. Factors include location, weather, trees, and traffic nearby.

Is it worth hiring a professional window cleaner?

Yes, for safety and quality. Professionals have proper equipment for high windows, work faster, achieve streak-free results, and can spot window damage early. It saves you time and ensures safety, especially for multi-story homes.
