Lock snapping in 30 seconds: that is how long it takes to open a standard euro cylinder with nothing but mole grips.

Tightening the hinges takes minutes. We do it daily across London.

Your uPVC door won't lock? Before calling anyone, try this: lift the handle firmly while pushing the door gently inward. If the hooks engage, it's misalignment and a hinge adjustment usually cures it. If they don't, it's the multipoint gearbox or the euro cylinder. We repair uPVC mechanisms from 99 GBP and change cylinders from 69 GBP labour, with no call-out fee.
