ONE TIME CLEANINGS One-time cleanings include move-ins and move-outs, spring-cleaning, service prior to a big event and other non-recurring services. All one-time services can be estimated. If additional time is needed, a HOUSEKEEPING representative will attempt to contact you while our staff is in your home. If you authorize additional time, our staff will continue to clean and your price will be adjusted accordingly. We will not use additional time without your prior approval.
