door closer installation and repair can be appropriate when the door sags, rubs, sticks or has uneven gaps around the opening. Check the closer model against the ordinary door, mounting support and manufacturer limits before fitting or adjustment.
Signs: the door sags, rubs, sticks or has uneven gaps around the opening or the door closes poorly despite an otherwise sound visible opening. Causes: normal wear in hinges, latches or compatible mechanical hardware or loose fixings, minor alignment drift or ordinary timber movement.
The supplied template establishes bracket and body positions for the permitted arrangement. Existing holes may not match a new model. Sound ordinary fixing support is required; installation does not include structural reinforcement or modification of a rated opening.
Visible leakage or physical damage may make replacement more suitable than adjustment. Show the condition and model before buying parts. The ordinary service does not rebuild sealed hydraulic mechanisms or promise that a damaged closer can be restored by changing settings.
Install a suitable ordinary supplied surface closer, make permitted adjustments or replace an unsuitable leaking unit within the agreed scope. Limits: Ordinary non-rated surface-mounted mechanical units only. No fire, smoke or egress certification, powered systems, structural reinforcement or specialist mechanisms.
