Why does my door latch stuck?
The most common cause of sticking door handles is some kind of malfunction within the tubular latch itself. To test this, firstly open the door and check that there are no obvious obstructions on the tubular latch plate such as loose screws, or signs of internal parts of the latch or lock poking through.
Why is my door not closing?
Wonky hinges are responsible for most door closing issues, so make sure to examine them before anything else. Loose screws or a door that appears to be sagging are the main signs that the hinges need a refresh.
