Window cleaning schedule for storefronts and offices in Spokane
October 15, 2026, 3 min read
In Spokane, storefront glass and entry doors need cleaning weekly to monthly, and office windows about once a quarter. Plan extra cleanings after spring pollen, late-summer smoke and the end of winter.
Customers judge a business by its glass before they walk in. Fingerprints on the door, a film on the storefront or streaks in the afternoon sun all send a message. Spokane's seasons add their own challenges, so a window schedule here works best when it follows the calendar.
A baseline schedule
- Entry doors and door glass: every visit, as part of janitorial cleaning
- Storefront glass: weekly to monthly, depending on traffic and the street
- Office windows, inside: quarterly
- Office windows, outside: two to four times a year
- Glass partitions and interior doors: monthly
Spokane through the seasons
Spring: pollen and the end of winter
When snow melts, road grime and de-icer spray leave a film on lower glass. Pollen follows in late spring. An exterior cleaning in April or May resets the building after winter.
Summer: dust and smoke
Dry summers bring dust, and in some years wildfire smoke leaves a haze on exterior glass. Plan a cleaning after smoky weeks clear.
Fall: before the cold
A full cleaning in September or October leaves glass clean going into winter, when exterior work gets harder.
Winter: inside and entries
In the coldest weeks we focus on interior glass and entry doors, which get the most fingerprints and slush splashes, and schedule exterior work on mild days.
