How Often to Clean Commercial Windows

Window cleaning frequency is the most over- and under-bought line in facility budgets. Set it by exposure and use, and you'll spend the right amount in the right places.

A Practical Frequency Matrix

• Retail storefront glass: weekly to twice-weekly in high-traffic districts — fingerprints, poster tape, and street splash are brand damage at eye level.
• Restaurant and café glass: 2–4× weekly, or fold exteriors into a morning porter route.
• Office low-rise / interior visibility: quarterly exteriors keeps views tenant-grade; high-visibility entries get monthly.
• Mid- and high-rise exteriors: 1–4 runs per year depending on neighborhood grime and tenant expectations — Class A Manhattan towers tend toward 2–4.
• Interior partitions and conference glass: monthly detail via your janitorial rotation.

Exposure Beats Habit

Ground floors facing bus routes or construction soil 3× faster than courtyard glass. Many properties save by putting street-facing elevations on a higher frequency than the rest — your vendor should propose this by elevation, not one flat rate for the building.

Scheduling Around Operations

Pole-system work from the sidewalk needs no notice for most properties; lift and descent work needs scheduling, permits, and pedestrian protection in New York. Book post-winter and post-construction runs early — every property manager in the city has the same idea in April.
