A door closer controls how a door shuts: speed, latching force and hold-open. When a door slams, will not latch, closes too slowly, or the closer leaks oil, we adjust or replace the closer so the door closes safely and latches every time.
When to call us
- The door slams shut.
- The door does not fully close or latch.
- Oil is leaking from the closer.
- The closer arm is bent or detached.
How the job works
- We check the closer, arm, door alignment and latch.
- Closing and latch speeds are adjusted where possible.
- Leaking or failed closers are replaced.
- Arms and mounting are repaired.
- The door is tested for safe closing and latching.
Adjusting a closer correctly
Most closers have separate valves for sweep speed, which controls how fast the door swings most of the way closed, and latch speed, which controls the last few centimetres. A door that slams usually needs a slower latch speed; a door that fails to latch needs a slightly faster latch speed or a stronger spring setting.
Adjustments should be small and tested in real conditions, because wind and building pressure change how a door behaves. A closer that leaks oil has failed seals and cannot be adjusted back into service; it needs replacing.
What affects the price
The dispatcher explains the service call before anyone is sent, and the technician confirms the total with you before starting any work that adds cost. The main price drivers are:
- Adjustment versus replacement.
- Closer grade and mounting type.
- Door weight and exposure.
- Hold-open or delayed-action features.
Hardware we see in Toronto
Surface-mounted and concealed closers, parallel-arm and regular-arm mounting, with hold-open and delayed-action options.
Door Closers in Toronto: local context
Wind off the lake, winter drafts and heavy foot traffic are hard on closers in Toronto storefronts and building entrances.
What we will and won't do
On fire doors, closers must remain functional and compliant; hold-opens must meet code.
