uPVC door repair – your questions answered
This is almost always a gearbox fault. The gearbox is the mechanism behind the handle that drives the locking points. When it fails, the handle lifts freely but the bolts do not engage. We carry gearboxes for all common uPVC door profiles on every van and replace them same visit.
