During this hot weather we are attending a lot of doors that cannot be locked. This is normally due to the doors being out of alignment. This most often happens to UPVC doors but can also affect wood and composite doors. If you have to use excessive force to lift the handle then very soon the mechanism is going to break. Your door should not be “knocking” when you shut the door with the handle held down.
It is far cheaper to get the doors adjusted before the mechanism breaks (possibly locking you in/out).
There is a fairly new housing estate in Coleford where we often go to conduct repairs. There’s also a new estate in Lydney with the same door mechanism. It isn’t the fault of the door mechanism, it’s the fault of the builders / installers who never took the time to line up the doors correctly to begin with.
