Door Entry System Common Faults
For repairs to door entry / intercom systems, as with many things, the hardest part is usually identifying the cause. The repair is usually the straight forward part.
More often than not faults with door entry systems will be found and repaired within an hour, for which a HomeForce technician will charge £65 plus any parts and parking. (See “Why trades people make a minimum charge”)
When a fault on a door entry system requires more extensive work to repair a technician will charge for his time doing his initial investigative work and provide a quote for the further works.
