Find the cause before replacing the lock
A door that catches or needs lifting to lock may have an alignment problem, a worn handle or a fault in the locking mechanism. Replacing the cylinder alone may not solve it. David checks how the door and lock work together to identify what needs attention.
Door locks, handles and mechanisms
DFM works on uPVC door locks and handles, including faults with multipoint mechanisms. Describe whether the key turns, whether the handle moves and whether the door is stuck open or closed. Photos of the door and its lock can help David understand the issue before visiting.
Window repairs and security
Loose handles, failing locks and worn window fittings can make a room harder to secure. David also handles window lock and handle problems. Call to discuss the type of window and the fault so he can advise on a suitable repair or replacement.
