It’s advisable to schedule move-in/move-out cleaning services well in advance, ideally a few weeks before your desired cleaning date. This allows you to secure a convenient time slot with the cleaning service, especially if you’re moving during a busy season. Booking early also gives you peace of mind, knowing that your cleaning needs are taken care of, and you won’t be rushed as moving day approaches. However, many cleaning services can accommodate last-minute requests, but availability may be limited, so it’s best to plan ahead when possible.
