Understanding the problem
Roller and sectional doors use different mechanisms, but both can develop problems with guides, rollers, alignment and general wear. The door type helps a repairer plan the visit.
What to include in your enquiry
Tell the repairer when the issue started, whether the door stops at the same point and whether there was an impact. Include the approximate age and door brand if known.
Before you book
Ask which parts need attention, what can be serviced and what may need replacing. The final quote depends on the fault, access and parts required.
