One of the tools I give my clients is emergency service. A handyman can be booked out for several weeks in advance, but emergency situations arise pretty frequently in this field of work. I intentionally keep Friday unscheduled every week so that I can handle situations that need immediate attention. I will either schedule that pressing work for Friday, or reschedule a client that was booked on another day that week to Friday if I have a situation come up that must be dealt with immediately.
