If you would like us to be at your home at a specific time, we recommend that you sign up for service at the beginning of the day (especially those with large size homes). As we clean homes during the day, we often encounter things that delay our arrival at our next home, like traffic, or a customer who would like some additional help. For afternoon service, we give you a two-hour window for when we expect to arrive but will do our best to be on time whenever possible. Should we be running behind schedule rest assured we will communicate with you.
