Why Your Door Slams or Won't Shut: Door Closer Problems
Slamming doors and doors that won't latch are usually a door closer fault — common on shops, offices and communal entrances. Here's the fix.
What a door closer does
A door closer (an overhead closer, concealed closer or floor spring) controls how a door shuts — smoothly, at the right speed, and fully into the latch. When it fails, the door either slams, drifts open, or won't shut properly.
These are common on commercial entrances, communal doors and fire doors.
Common closer faults
Closers can leak their hydraulic fluid, lose adjustment so they slam or close too slowly, or wear out so the door won't latch. Floor springs under heavy glass shop doors are a frequent failure point and a safety concern when they go.
A slamming fire door or one that won't self-close is also a safety and compliance issue.
How a locksmith fixes it
A locksmith can adjust the closing speed and latching action, or replace a failed closer or floor spring with the correct type — including BTS80, Dormakaba and Axim units carried for same-visit repairs where possible.
We repair and replace door closers and floor springs for shops, offices and communal doors across Catford and SE London.
