No. You are not required to be home at any point during your cleaning. That being said, if this is your first appointment, it’s usually a good idea to be present when the cleaning crew arrives so that you can provide them with a walk-through of your home. Once your cleaning is complete, it’s also a good idea to walk through the home again in order to ensure that everything is to your satisfaction.
Spend your time doing what you love and leave the cleaning to us!
