We understand your time is valuable! When we schedule your service appointment we do not give appointment windows (i.e. between 2pm-4pm). Appointments are scheduled at a specific time. If we schedule an appointment for 10 am we usually arrive several minutes prior to the scheduled appointment time. If we are running behind due to our previous appointment we will call ahead and let you know what our adjusted arrival time will be. Rarely are we late but we do not rush one appointment to make the next appointment. We will not sacrifice quality!
