Technicians can be booked by the hour, with a minimum visit/callout duration of 1 hour.
The technicians will work for as long as necessary to compete the job (irrespective of the number of hours booked by you). If a job can not be completed on the same day, then you will be advised of that by the technicians.
For complex jobs, ServiceMarket can provide lump sum quotes for the complete service. You can reach us on support@serviemarket.com for such inquiries.
