03 — Warning signs

Eight signs your door needs attention

Catch these early and the repair is small. Ignore them and you risk damage, injury liability and compliance failures.

The door slams shut or closes too fast.The closer has lost hydraulic control — an injury risk on commercial premises.

Oil is leaking from the door closer body.Seals have failed; the closer will stop controlling the door entirely.

The door won't fully close or latch on its own.A security and fire-compliance failure, not just an annoyance.

Dragging, scraping or grinding along the floor.Worn hinges or pivots letting the door sag out of alignment.

Handles, locks or panic bars feel loose or floppy.Fixings and internals wear — cheap to fix early, costly after failure.

The key is hard to turn, or the lock sticks.Misaligned strike or worn cylinder — often minutes to correct.

The door drifts open on its own.Frame or hinge misalignment defeating the closer.

Excessive force is needed to open the door.An accessibility compliance issue for public and commercial buildings.
