Overview
A door closer decides whether a door actually latches. Set wrong, it either slams or drifts shut without engaging the latch — and a door that does not latch is an unlocked door, regardless of how good the lock is. We size the closer to the door's weight and width, mount it, and set the sweep and latch speeds so it closes properly every time.
A door that does not latch is an unlocked door
The closer decides whether your door actually engages its lock. Set too weak, the door drifts to rest against the strike without latching — and every lock on it becomes decoration. Set too strong, it slams: hard on the hardware, the glass, and everyone who uses the door. The failure is invisible because the door looks closed; you find out when the alarm company calls, or when the inspection does. Fitting and adjusting closers correctly is unglamorous work that quietly carries the security of the whole doorway.
Sized to the door, tuned to the people
Closers are rated by door weight and width — an undersized unit fails within a year, an oversized one turns the door into a workout. We size to the actual door, mount it, and set the two speeds that matter: sweep, so the door closes at a civilised pace, and latch, so the final inches carry enough energy to seat the latch every time — not most times. Opening force is kept low enough that the door stays usable for people who cannot pull hard, which on accessible routes is not a courtesy but a requirement.
The visit
Step 1: Assess the door
Weight, width, traffic and exposure — the numbers that pick the closer, and a check of hinges and alignment that adjustment cannot fix.
Step 2: Size and mount
The correctly rated closer, mounted to the door and frame the way its template intends, not the way the last one happened to be.
Step 3: Set sweep and latch speed
The door closes smoothly and finishes with enough force to latch — verified over repeated closes, not one lucky one.
Step 4: Confirm the latch, every time
The test that matters: the door latching itself from a range of opening angles, so “closed” means locked, not resting.
Included
Sized to the door rather than fitted generically, which is why cheap closers fail within a year
Latch speed set so the door engages the strike on every close, not most closes
Adjusted to stay easy enough to open in everyday use, including for people who cannot pull hard
Questions
Sometimes it is only adjustment: closers have separate sweep and latch valves, and a slam is often a latch speed set wide open. If the closer has lost fluid or the valves no longer hold a setting, it is done — we tell you which case yours is before replacing anything.
