Window Cleaning FAQs

How much does window cleaning cost in San Francisco?

Window cleaning costs vary based on number of windows, accessibility, and property type. Residential: $150-400 for average home. Commercial: $200-1,000+ depending on building size. We provide free quotes. Call 415-725-0999 for exact pricing.

How often should windows be professionally cleaned?

Residential: 2-4 times per year (seasonally). Commercial storefronts: Monthly or bi-monthly. Office buildings: Quarterly. High-traffic or coastal properties may need more frequent cleaning due to salt air and pollution.

Do you clean windows in the rain?

We generally reschedule for heavy rain, but light rain or overcast days are actually ideal for window cleaning! Windows dry more slowly, reducing streaks. Rain after cleaning won't make windows dirty - it's the dirt particles rain carries that causes spots.

Can you remove hard water stains from windows?

Yes! We specialize in removing hard water stains, mineral deposits, and oxidation from windows. This may require additional treatment and specialized solutions. Severe staining may need multiple treatments for best results.
