The standard appointment allocates an arrival window in which a technician will arrive.  The technician may arrive at any time within this period. Standard Appointments are usually available as a next day service. This affords us time and flexibility to manage the variability of job times and travel, and as such is the most affordable type of on-site service. Prices start from $110 per hour.  A minimum of 1 hour is charged for each visit and surcharges may apply depending on the service required.
