If you’ve ever looked at your windows and wondered, “Is it time to clean these again?” — you’re not alone. Window cleaning frequency depends on several factors, from your location to the type of building and exposure to dirt, dust, or weather. Knowing how often to schedule professional cleaning can help protect your glass and keep your home or business looking its best year-round.

🏡 Residential Window Cleaning

For most homes in the Inland Empire, professional window cleaning is recommended at least twice a year — typically in spring and fall. These seasons bring moderate weather and help reset after the buildup of:

Pollen and dust in the spring
Water spots, smog, and grime in the summer
Rain and mineral deposits in the winter

If you live near major roads or construction zones (common in Rancho Cucamonga, Ontario, or Riverside), consider cleaning every 3–4 months for best results.

🏢 Commercial Window Cleaning

For businesses, frequency depends on visibility and traffic:

Retail stores, cafés, and restaurants: Every 2–4 weeks. Customers notice dirty windows quickly.
Office buildings: Every 6–8 weeks, depending on foot traffic and exterior exposure.
Warehouses or industrial buildings: Every 3–4 months to maintain light and visibility.

Clean windows directly affect curb appeal and customer impressions, especially for storefronts and entryways.

🌦️ Local Factors in Southern California

The Inland Empire’s dry climate and frequent winds mean windows accumulate dust and mineral deposits faster than coastal areas. Seasonal Santa Ana winds push large amounts of dust and debris across neighborhoods, leaving windows and screens dirty even after just a few weeks. Add in pollen season, wildfire smoke, and the occasional heavy rain, and it’s clear why a consistent cleaning schedule makes a difference.

Regular maintenance helps prevent permanent glass etching caused by hard water, pollutants, and wind-driven dust — something Ecoworks sees often during service calls.
