We recommend keeping some contingency time just in case the assignment takes a little longer to complete, or if the cleaning professional is running behind schedule in arriving. Most of the time they arrive on time or even early but occasionally there are delays. It is not unusual with the majority of our customers, particularly those that live in larger homes to keep their calendar clear the day of cleaning or to arrange for the cleaning assignment to take place the day before an event such as a party – this alleviates possible frustration and nervousness. We want our customers to be relaxed and stress free and for the cleaning to go hopefully like clockwork.
