DOOR ALIGNMENT & MOVEMENT

Door Keeps Closing by Itself

A door that keeps closing by itself may be hanging out of plumb, affected by hinge alignment or controlled by a fitted door closer.

!

Check the door type before altering it

Fire doors, security doors, glazed doors and external doors may need specialist adjustment. Do not remove excessive timber or disable closers, seals or locking hardware.

MOST LIKELY CAUSES

Start with hinges, gaps and the first contact point

Frame out of plumb Gravity pulls the door toward the closed position.
Hinge line misalignment The hinge pins are not vertically aligned.
Door closer action A fitted closer is designed to shut the door.
Air pressure Extract systems or draughts can pull the door closed.
◫ Symptom variations Match the movement, rubbing and closing pattern. ⌄
  • Door swings shut from any position
  • Door closes faster near the frame
  • Movement changes when windows open
  • Door slams
  • A closer is fitted above the door
✓ Quick checks Simple checks before trimming or moving hardware. ⌄
  1. Check for a door closer.
  2. Switch off nearby extractors temporarily.
  3. Use a level on the frame.
  4. Check hinge screws and hinge wear.
  5. Observe whether the door accelerates near closing.
Important: Mark the exact cause before making adjustments. Random trimming can create bigger gaps without fixing the real fault.
1 Step 1 — Identify whether a closer is responsible Make the smallest safe correction and recheck the door. ⌄

Do not alter a fire-door closer without understanding its purpose.

2 Step 2 — Check hinge and frame alignment Make the smallest safe correction and recheck the door. ⌄

Secure loose hinges and confirm the hinge line is vertical.

3 Step 3 — Correct the cause Make the smallest safe correction and recheck the door. ⌄

Adjust only suitable hardware or have the frame reset if badly out of plumb.

⌁ Why the problem happens How hinges, frames, timber and gravity affect the door. ⌄

Gravity moves a door when the hinge axis leans. A closer or room pressure can add to the movement.

⌘ Advanced checks Further diagnosis for persistent alignment faults. ⌄
  1. Check closer make and adjustment instructions.
  2. Check latch and seals for resistance.
  3. Measure frame plumb.
  4. Inspect hinge knuckles for alignment.
  5. Check room pressure with extract fans operating.

? Frequently asked questions Common door alignment questions. ⌄

Should a fire door close by itself?

Usually yes. Fire doors commonly use self-closing devices.

Can I disconnect the closer?

No. That can compromise fire safety.

Why does it close only when the extractor is on?

Air pressure may be pulling the door toward the room.
