CORE™ decision support
The short answer: frequency is usually the single largest lever on monthly commercial cleaning cost — larger than square footage. More visits per week means a higher monthly total, but fewer visits means more work (and often more cost) per individual visit, because soil, trash, and wear accumulate between cleanings. The right frequency depends on occupancy and traffic, not habit or what a neighboring building does.
Frequency multiplies almost every other cost driver: restrooms, trash, floors, and touchpoints all get touched on every visit, so going from 2x to 5x per week doesn't just add visits, it multiplies the recurring labor. This is why two identical buildings on different frequencies can have very different monthly costs even though nothing else changed.
A quiet single-tenant office with light foot traffic often holds up fine on 2-3x per week. A public-facing lobby, a medical suite, or a high-traffic multi-tenant building usually needs nightly service to stay presentable and sanitary during business hours. Occupancy days per week matters too — a 5-day office doesn't necessarily need 5x cleaning if usage is light.
Less-frequent service is not proportionally cheaper. A building cleaned once a week accumulates five days of soil and trash by the next visit, which means more time on-site, more supplies, and sometimes a larger crew per visit. Compare frequencies on both monthly total AND average cost per cleaning — the second number often changes the decision.
Complaints about appearance between visits, overflowing trash before the next cleaning, or a lobby that looks tired by midweek are signs of under-frequency. A largely empty checklist and cleaners with little to do each visit can be a sign of over-frequency relative to actual use.
Most occupied offices land on 3-5 nights per week; light-traffic single-tenant space can work on 2x; high-traffic, public-facing, or medical space usually needs 5x (nightly on business days).
No. Monthly cost increases with frequency but not linearly, and per-visit cost typically goes down slightly as visits get shorter and more routine.
It can work for very light-traffic space, but expect a longer, more thorough (and costlier per-visit) cleaning each time, and be realistic about how the space looks by day 5.
Not necessarily — cleaning frequency should track occupied days, not calendar days. A Monday-Friday office with light weekend use rarely needs weekend service.
Use the CORE calculator to run your building's profile at two or three frequencies side by side and compare both the monthly total and the cost per visit.
Yes. Frequency is one of the easiest things to adjust once you have real experience with how the space holds up, and a reputable provider should accommodate a frequency change without a full contract renegotiation.
