Door closer service contracts — overhead, transom and concealed closers tuned and serviced to BS EN 1154 standards, the closer-side equivalent of the annual MOT.
Door closers are the most over-looked and least-understood piece of door hardware. They have 2–4 internal valves that need periodic tuning to compensate for spring relaxation, weather-driven frame movement and seal hardening. A correctly-tuned closer brings the door home in 4–6 seconds with a positive latch; a mis-tuned closer slams, stops short, or refuses to close at all. Every uncontrolled close shock-loads the pivot, hinges and glazing. A service contract catches the drift before it becomes the cascade-failure pattern that destroys the rest of the door.
Door closers must comply with BS EN 1154 (controlled door closing devices). Closers on fire doors must additionally be CE/UKCA marked for fire performance to BS EN 1634-1 and must close the door fully from any open position. Closers on accessibility-required entrances must allow opening within BS 8300 force limits (typically <30N). Closers fitted to electromagnetic hold-open systems must release on fire-alarm signal.
Wherever your premises are, the same engineer team carries your documentation between visits. One contract, one accountable team, one document trail — whether you have a single site or a multi-region estate.
Annual is the sensible baseline for most commercial closers. Six-monthly for closers on doors that get heavy weather exposure (external entrances on a windward face) or seasonal frame movement. The valve tuning is a 5-minute job at each visit and is the single biggest determinant of closer working life.
Replacement once internal seals leak — the body is sealed and not field-serviceable. The value of a service contract is catching the early-stage leak before the closer fails outright, so replacement can be scheduled outside trading hours at standard rate.
Overhead and transom closers are covered as standard door closer line items. Floor springs are a separate door type with their own service-contract page — they're the same hydraulic principle but mounted at floor level and serviced differently. Both can be combined in a single multi-line contract.
Tested at every visit — activation by fire-alarm signal must release the door reliably so it self-closes. Failure to release on test is a critical fire compliance issue, immediately flagged and quoted for remedial work.
A repeatedly-loosening closer usually means the door material is too soft for the standard fixings (often the case on hollow aluminium doors). Solution is either through-bolting, blind bolt fixings, or in extreme cases a reinforcing plate. Quoted separately at the service visit.
First visit typically within 2–3 weeks of contract sign-off. Emergency response priority kicks in from contract start date.
A short email or a photo of your door inventory is all we need. No site visit required in most cases.
