Fixing Common Door Problems: Sticking, Squeaking, Scratches and Swelling

Almost every door develops a small problem sooner or later. The good news is that most of them are simple to diagnose and often easy to fix. This guide covers the four most common complaints, what usually causes them and when it is wiser to call a carpenter.

A door that sticks or rubs

Start by finding where the rubbing happens. Close the door slowly and look for shiny or worn marks on the edge or the frame. The usual causes are:

• Loose hinge screws. The leaf sags slightly and its corner drags. Tightening the screws, especially the top hinge, often solves it.
• A frame that has moved. Settling of the wall or a poor installation can shift the frame out of plumb.
• Swelling from moisture. Wood-based leaves can take on moisture, particularly at the edges.
• Thick paint or finish build-up on the edge or in the frame.

If a screw hole is stripped, a common repair is to fill it with small wooden sticks and glue, then re-drive the screw. Do not remove material from the leaf until you are sure that the hinges and frame are fine, because cutting is hard to undo.

A door that squeaks

Squeaking almost always comes from dry or dirty hinges. Support the door, remove the hinge pin if possible, clean it and apply a suitable light lubricant, then replace it. Wipe off any excess so it does not drip onto the finish. If the noise continues, check for loose screws and for a latch that rubs on its strike plate.

Scratches and small damage

The right repair depends on the surface:

• Painted doors: light scratches can be touched up with matching paint after gentle cleaning. Deeper ones may need filling and sanding first.
• Melamine and HPL: surface scratches are harder to repair invisibly. Color-matched repair fillers or markers can hide minor marks, while chipped corners may need a professional.
• PVC: very light marks may blend in with careful cleaning, but deep scratches usually remain visible.

Whatever the surface, cover exposed edges promptly, because a break in the finish lets moisture reach the core.

Swelling and warping

Swelling usually appears at the bottom edge or around the lock, where water and humidity enter most easily. Warping can come from uneven moisture on the two faces of the leaf or from heavy sun on one side.

• Find and stop the source: leaking pipes, wet mopping against the door, or a damp wall.
• Let the leaf dry naturally with good ventilation. Do not use strong heat.
• Once dry, check whether it returns to shape. Minor swelling often does, to some extent.
• Seal exposed edges so the problem does not repeat.

Serious warping or soft, crumbling material is usually a sign that the leaf should be replaced rather than repaired.

When to call a carpenter

• The frame is out of plumb or loose in the wall.
• The leaf needs trimming or the hinge recesses need adjustment.
• The lock does not line up with the strike plate even after tightening.
• Swelling is deep or the surface is peeling.

How to choose what suits your home

• Humid rooms: choose finishes and edge sealing designed for moisture, such as PVC or HPL, to reduce swelling risk.
• Busy households: a harder surface such as HPL resists everyday scratches better.
• Heavy leaves: insist on enough good-quality hinges to prevent sagging and sticking.
• Budget: a well-made door fitted carefully costs less over the years than repeated repairs.
• Maintenance: a quick yearly check of screws, hinges and edges prevents most of the problems above.
