DOOR ALIGNMENT & MOVEMENT

Door Won’t Close Properly

A door that will not close properly usually has hinge movement, timber swelling, frame distortion or a latch that no longer lines up with the strike plate.

!

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

Loose or worn hinges Movement at the hinge side changes the door position.
Swollen timber Moisture can make a wooden door expand and bind.
Frame movement Settlement or seasonal movement can alter the opening.
Latch misalignment The latch may sit above, below or beside the strike opening.
◫ Symptom variations Match the movement, rubbing and closing pattern. ⌄
  • Door nearly closes but springs back
  • Latch misses the strike plate
  • Top or bottom corner catches
  • Door only closes when lifted
  • Problem changes with weather
✓ Quick checks Simple checks before trimming or moving hardware. ⌄
  1. Open and close the door slowly to find the first contact point.
  2. Check every hinge screw for movement.
  3. Look for shiny rub marks on the door or frame.
  4. Check whether the latch enters the strike plate centrally.
  5. Compare gaps at the top, sides and bottom.
Important: Mark the exact cause before making adjustments. Random trimming can create bigger gaps without fixing the real fault.
1 Step 1 — Tighten and assess the hinges Make the smallest safe correction and recheck the door. ⌄

Tighten loose screws and replace damaged screws with suitable longer fixings into sound timber where appropriate.

2 Step 2 — Correct minor rubbing Make the smallest safe correction and recheck the door. ⌄

Mark the exact contact point and make only the smallest adjustment needed.

3 Step 3 — Realign the latch Make the smallest safe correction and recheck the door. ⌄

Adjust the strike plate only after the door itself is sitting correctly.

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

Doors rely on a square frame, secure hinges and accurate latch alignment. A small movement at the hinge can create a much larger change at the closing edge.

⌘ Advanced checks Further diagnosis for persistent alignment faults. ⌄
  1. Check the frame diagonals for squareness.
  2. Use a straightedge to check for bowed door or frame sections.
  3. Check hinge leaves for bending or wear.
  4. Inspect for moisture damage around the frame.
  5. Confirm floor finishes have not reduced the clearance.
◇ Tools and information needed Useful items for accurate checks. ⌄
  • Screwdriver
  • Pencil or chalk
  • Straightedge
  • Tape measure
  • Spirit level
▣ Parts or improvements that may help Common items linked to this problem. ⌄
  • Replacement hinge screws
  • Hinges
  • Strike plate
  • Timber repair filler
  • Suitable door seal
! When to call a professional Conditions that should end basic DIY diagnosis. ⌄
  • The frame is badly distorted.
  • There is rot or significant moisture damage.
  • A fire door is affected.
  • The door is external and no longer weather-seals.
  • The repair would require major trimming or rehanging.
? Frequently asked questions Common door alignment questions. ⌄

Why does lifting the handle help the door close?

This usually points to hinge movement or a sagging door.

Should I move the strike plate first?

Only after checking the door position. Moving the plate can hide the real cause.

Can weather cause this?

Yes. Timber doors can expand in humid conditions and shrink when dry.
