Timber Moves, Houses Settle: A Sensible Guide to Winter Doors That Stick, Shrink or Squeak

There is a particular noise a house makes in November. The heating clicks on, the air dries out, and suddenly the hallway door catches on the carpet, the bedroom door rattles in its frame, and a floorboard in the front room develops a squeak it has kept quiet about all summer. It can feel like the house is falling apart. In most cases, it is just timber doing what timber does.

Wood is hygroscopic, which is a fancy way of saying it takes in and gives out moisture depending on the air around it. As the heating comes on and the indoor air dries out, wooden doors, frames and floorboards lose a little moisture and shrink. In the damper months they swell again. It is not a fault. It is a characteristic of the material, and it is worth understanding before you reach for a plane or a tube of filler.

What is actually happening to your woodwork

Most interior doors in UK homes are either solid timber, engineered timber or a hollow core with a timber frame. All of them respond to humidity, though to different degrees. A solid pine door in a Victorian terrace may move more than a modern engineered door, but even MDF and veneered doors can shift enough to affect the latch or the gap around the edge.

When relative humidity drops, timber shrinks across the grain. That can mean a door slab becomes slightly narrower, so gaps appear at the lock side. It can mean floorboards shrink away from each other, leaving thin dark lines. Hinges can feel loose because the screw holes have dried out a fraction. And a door that was perfectly adjusted in July may now sit a millimetre or two differently in its frame.

Sticking is often the opposite problem: damp weather makes external doors swell, or a bathroom door swells after every shower. In winter, an internal door can also stick if the frame has moved, if paint has built up in the rebate, or if the house has settled. A squeak is usually just two surfaces rubbing together without enough lubrication.

The difference between weather and worry

A bit of movement is normal. What you want to rule out is a genuine fitting problem or a damp issue that will get worse if ignored. A few simple checks will tell you most of what you need to know.

Start with the gap. Close the door and look at the space between the door edge and the frame. A consistent gap of a few millimetres at the top and sides is fine. If the gap is even but the door rattles, the latch may simply need adjusting. If one corner is tight and the opposite corner is wide, the frame may be slightly out of square, which is common in older houses but worth monitoring.

Next, check for damp. Look at the skirting board, the wall beside the frame and the floor underneath. Dark patches, bubbling paint, a musty smell or white salt deposits are signs that moisture is involved, not just dry air. If a door sticks only after wet weather and the wall nearby feels cold or damp, treat it as a ventilation or damp question before you treat it as a carpentry question.

Finally, check the hardware. Loose hinge screws are behind a surprising number of door problems. A latch that has started to rub can usually be solved by a small adjustment to the strike plate. A squeaky hinge often just needs a drop of silicone spray or a light oil, not a new door.

Simple adjustments you can make safely

If the hinge screws have worked loose, tighten them gently with a screwdriver. If the holes are worn, you can pack them with a matchstick and a little wood glue, then replace the screw once it has dried. Do not overtighten, especially in older softwood frames.

For a latch that is catching, look at the strike plate on the frame. Sometimes it has moved a fraction, or the screw has pulled. You can loosen it, nudge it a millimetre or two and tighten it again. If the plate itself is binding, a light rub with a fine file may be enough. Go slowly. It is much easier to remove a little more metal than to put it back.

Squeaky hinges respond well to lubrication. Squeaky floors are trickier. A little talcum powder worked into the gap between boards can quieten a small squeak, but avoid soaking the wood with water-based products. If a floorboard has lifted enough to trip on, that is a different job and worth getting looked at properly.

One thing to resist is planing a sticking door in November just because it is catching now. If the sticking is caused by damp or by a door that has swollen in the wet weather, planing it may leave an ugly gap when the wood shrinks again in spring. Wait for a dry, stable spell and see whether the problem persists. If it does, plane a tiny amount at a time and check the fit often.

Keep an eye on the indoor air

A cheap hygrometer is a useful kitchen-drawer tool for a homeowner. Indoor relative humidity of roughly 40 to 60 per cent is a sensible target. Very dry air can make timber shrink and gaps appear, while very humid air encourages swelling and condensation. Opening trickle vents, using extractor fans in the bathroom and kitchen, and avoiding drying laundry indoors without ventilation will all help keep things steady.

Do not block up every draught in an old house and then wonder why the windows stream with condensation. Timber needs a stable environment, and so do you.

When to call a carpenter

Bring in a professional if a door has dropped so much that it will not latch at all, if the frame is visibly twisted, if hinge mortises are cracked, or if you have already adjusted the hardware and the door still binds. Also call someone if an external door is letting in water, or if you suspect damp behind the frame. Those are not seasonal quirks.

For most November door problems, though, a screwdriver, a pencil, a hygrometer and a little patience will see you through. Timber moves because it is a natural material in a changing house. A door that sticks in winter and frees up in spring is not failing. It is just telling you what the weather is doing.
