Sliding balcony door repair in Kensington SW7.
The sliding door mechanism has become detached from the handle mechanism. The handle mechanism is working from the outside but not from the inside.
Therefore the door is jammed shut. There is an identical sliding door on the balcony on the above floor which is working and this allowed us to see how the mechanism works.
There is no way of establishing where the fault is. Because there is no way of getting to the mechanism without opening the door. The door will have to be opened using specialist tools before a full survey can be done.
