A one-time deep clean resets a neglected building fast, but the standard fades within weeks. A recurring plan costs less per visit and holds the building at standard all the time — no rescue cleans, no frantic calls.

Do the math over a quarter, not a week. Three months of steady visits almost always beats a deep clean plus two months of slide, especially once you add the hours you spend managing it.

The hybrid move works well: start with a deep clean so the crew sees the building at its best, then roll straight into the recurring plan that keeps it there.
