DOOR ALIGNMENT & MOVEMENT

Door Dragging on Floor

A door dragging on the floor is usually caused by hinge movement, a sagging door, a raised floor finish or timber swelling.

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 top hinge A small hinge movement lowers the opposite corner.
Worn hinges Pins or leaves can develop play.
Raised floor finish New carpet or flooring reduces clearance.
Swollen lower edge Moisture can expand the timber.
◫ Symptom variations Match the movement, rubbing and closing pattern. ⌄
  • Door scrapes carpet
  • Bottom corner catches
  • Door closes when lifted
  • Marks appear on flooring
  • Problem started after new flooring
✓ Quick checks Simple checks before trimming or moving hardware. ⌄
  1. Check the top hinge first.
  2. Look for hinge pin movement.
  3. Measure floor clearance across the opening.
  4. Check whether the floor itself is high or uneven.
  5. Inspect the lower edge for moisture swelling.
Important: Mark the exact cause before making adjustments. Random trimming can create bigger gaps without fixing the real fault.

3 Step 3 — Trim only when necessary Make the smallest safe correction and recheck the door. ⌄

Remove the minimum amount and reseal the lower edge.

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

The closing edge of a door acts like a lever. Tiny movement at the hinges can make the bottom corner drop enough to scrape the floor.

⌘ Advanced checks Further diagnosis for persistent alignment faults. ⌄
  1. Check hinge mortises are not crushed.
  2. Check the frame is secure.
  3. Measure door squareness.
  4. Inspect thresholds and flooring transitions.
  5. Check for moisture at the lower edge.

? Frequently asked questions Common door alignment questions. ⌄

Can I just cut the bottom off?

Check hinges and floor height first. Trimming too much can leave a poor gap.

Why does the top hinge matter?

A loose top hinge lets the far bottom corner drop.

Should I seal the trimmed edge?

Yes, especially on timber doors.
