The build

Hi Mikey. Its a disabled access supposedly stable door, but it not what I really wanted. He built it in a door frame with a tilt and turn window at top, that was first to break. Its in the kitchen extension, so seems to be set into a upvc surround, which has the locking system in. Its the lock and hinges that is really broken, as it seems to have dropped but there is no adjustment left. My husband can fit yale locks, so hoping he can fit the weird upvc lock.

What type of door is it, wood or UPVC. If the first that’s easy enough and reclamation yards carry old doors so a quick call should find something . The latter in a stone building is a bit harder as you need to measure from outside and measure its narrowest points. You infill the gaps then with expanding foam before cutting some thin plastic to cover the foam. There are a few miss measure upvc companies in South Wales where you can pick up new doors more cheaply.
