How to estimate cleaning labor hours

Calculate person-hours before assigning a crew. Two cleaners working for two hours use four labor hours, even though the visit lasts two hours.

A situation to work through
A job needs six person-hours. Three cleaners may finish in about two hours if tasks can run in parallel; shared equipment and access can change that duration.

Work through the decision
Estimate the tasks in person-hours, add setup and agreed non-cleaning time, then identify which tasks can run simultaneously. Divide only the parallel portion by available crew members. Compare the resulting visit length with the customer's service window.

Before you hand over the result
Do not divide blindly by crew size. Travel, setup and tasks in a single small room may not shrink proportionally.
