Choose based on use—not a rule
Weekly service can make sense for larger households, frequent entertaining, heavy kitchen use, or homes with pets. Biweekly service may suit smaller households with steady routines and lighter day-to-day use.
Look at the reset between visits
If the home feels difficult to recover before the next visit, a more frequent schedule or a narrower priority list may help. If surfaces and floors stay manageable, biweekly service may be enough.
Revisit the plan
Schedules change. Ask for a plan that can be reviewed after the first few visits rather than treating frequency as permanent.
