Often adjustment
Door slams or closes too fast
Closing speed and latching action set too aggressively, or drifting out of adjustment over time. Usually corrected on the existing device where it is otherwise sound.

Fire Door Closers: Adjustment, Repair & Replacement
A fire door that does not close and latch fully, every time, is not doing the job it was fitted for. This page is for landlords, block managers and property teams dealing with doors that slam, stick, stop short of the latch, or have closers that have been removed altogether.
What a Closer Fault Actually Looks Like
Closer defects rarely announce themselves as closer defects. They arrive as complaints — the door bangs at night, the door is too heavy for an elderly resident, the door has been propped open with a fire extinguisher — or as a line on an inspection report saying the door failed to close and latch from any angle.
Our first job on site is to establish which it is. A door that will not latch may have a tired closer, or it may have dropped on its hinges, or the latch may be catching a misaligned keep, or the seals may have been painted until the leaf binds in the frame. Fitting a new closer to a door with a hinge or alignment problem simply forces the fault through a new device.
Adjustment, Repair or Replacement
Often adjustment
Door stops short of latching
Insufficient latching action, or resistance from seals, carpet or a binding leaf. Adjusted where the device has the range, investigated further where it does not.
Usually replacement
Leaking or seized device
Oil staining down the leaf, jerky travel or a device that has lost its power. Internal seals cannot be renewed reliably in situ, so a compatible replacement is the sound route.
Depends on evidence
Device not suited to the leaf
An underpowered or unsuitable closer struggling with a heavy leaf, or a device fitted in an arm arrangement it was not intended for. Specification comes from the doorset and device documentation.
Reinstatement
Closer removed or arm disconnected
Very common on communal and flat entrance doors. Reinstated with a compatible device, with fixing points made good where the previous installation has torn out.
Wider works
Fixings pulled out of leaf or frame
Where fixing zones can no longer hold, making good may be possible; where the leaf or frame has been repeatedly cut about, replacement of the doorset is often the more defensible outcome.
Specification Comes From the Doorset, Not a Rule of Thumb
There is no single closer that belongs on every fire door. Device power, arm arrangement, fixing method and any intumescent protection required behind the device all relate to what that doorset was tested and documented with, and to how the door is used.
Where the doorset can be identified, we match the replacement device to that evidence and to the manufacturer's installation instructions. Where it cannot be identified, we say so plainly rather than fitting something that looks right and calling the item closed.
- Device matched to the doorset documentation and manufacturer instructions
- Fixing method and any specified protection behind the device observed
- Closing speed, latching action and back-check set and tested on completion
- Door checked to close and latch from a range of opening angles
- Associated hinge, seal, latch and alignment defects checked at the same visit
- Device and settings recorded against your door reference
Closer Work in Occupied Buildings
Most closer work happens in buildings full of people. Communal doors are done without leaving escape routes obstructed, and flat entrance doors are left secure and working before we leave the property. Our guide to remedial works in occupied buildings sets out how access and sequencing are planned.
If you hold an inspection report or fire risk assessment action list, send it over and we will price the closing and latching entries against your door references, along with the hinge and latch and lock items usually recorded on the same doors. Where a formal fire door inspection report is required, that can be arranged through a specialist fire door inspection contractor; our own site assessment confirms remedial scope and is not a formal inspection report.
