Why a Timber Gate Rewards Regular Attention

Few features say British countryside quite so plainly as a well-hung wooden gate — whether it is a five-bar field gate, a close-boarded pedestrian gate at the end of the lane, or a modest wicket opening onto a kitchen garden. They all do the same job, and they all tend to fail in the same order. First the joints loosen. Then water finds its way into the end grain and the bottom rail. Rot takes hold quietly, often out of sight behind a hinge or beneath a coat of paint, and by the time the gate is hanging at a drunken angle the repair bill has trebled.

The reassuring truth is that a well-made timber gate, properly looked after, will comfortably outlast the person who hung it. It does not ask for much: a careful inspection twice a year, and a willingness to deal with small problems before they become structural ones.

The Twice-Yearly Inspection

Walk your boundary after the first proper gales of autumn and again in late spring, once the worst of the wet has passed. Take a notebook and a small flat-bladed screwdriver, and check four things at every gate.

• Joints and bracing: look for gaps opening at mortise-and-tenon joints, pegs working loose, and movement in the diagonal brace.
• Ground clearance: the gate should clear the ground by 25–40mm. If it is dragging or the bottom rail is permanently damp, it will rot from below.
• Ironwork: check for worn hinge pins, loose screws, and a latch that has stopped meeting its keeper cleanly.
• Timber condition: probe the bottom rail, the foot of the hanging stile and any point where the gate meets its post. Sound timber resists the screwdriver; soft, dark, spongy timber does not.

Note anything that has changed since last time. A gate that will not stay shut is rarely a latch problem — it is almost always a frame that has moved.

Tightening Joints and Correcting Droop

A wooden gate is meant to move a little with the seasons, but it should not rattle. Where a joint has opened, draw it back with a sash clamp, work exterior-grade polyurethane glue into the gap — not ordinary PVA, which softens with damp — and drive a slightly oversized hardwood peg or stainless steel screw through the original fixing point. If a peg is loose in its hole, drill it out to the next size up and fit a fresh oak or ash dowel, glued and tapped home, then cut flush.

A gate that has dropped on its hinges usually needs the brace looking at. On a ledged and braced gate, the diagonal should rise from the hinge side at the bottom to the latch side at the top. If it runs the other way, the gate is braced against itself and will sag for the rest of its life. Correct the brace before you touch the hinges, or you will simply be adjusting a symptom.

Treating the Timber Without Trapping Moisture

Timber needs to breathe. A gate sealed under thick varnish will blister, crack and then hold water against the wood far more effectively than it ever kept it out. Stick to penetrating finishes: boiled linseed oil, Danish oil or a good quality wood preservative. Apply two or three thin coats on a warm, dry day, working with the grain, and keep going on the end grain until it stops drinking. Never treat a gate in direct hot sun, and never apply a finish to damp timber.

Where you find localised wet rot, cut back to sound timber, treat the exposed area with a boron-based gel or paste, and let it dry thoroughly before filling with an epoxy wood repair compound. Watch for dark staining around fixings: oak contains tannic acid, which corrodes ordinary steel and leaves black streaks. Always use stainless steel, hot-dip galvanised or silicon bronze fixings on hardwood gates.

Hinges, Latches and Ironwork That Lasts

Ironwork fails slowly and then all at once. Hook-and-band and T-hinges should be greased once a year with a little white grease or petroleum jelly — not engine oil, which attracts grit and turns into a grinding paste. If the screws have loosened, the holes are worn. Glue a hardwood dowel into each hole, cut it flush, drill a pilot hole and refit. A screw driven back into a worn hole will simply work loose again within a season.

When a hinge pin is genuinely worn through, replace the hinge rather than feeding it more grease. Check the latch keeper too: it is common for the gate to have moved a few millimetres while the keeper has stayed put, which is why the latch suddenly needs a shove.

Posts, Clearance and the Yearly Rhythm

Most gate failures begin at the post, not the gate. Rot sets in at ground level, where damp and air meet the timber, and works upwards unseen. Keep the base clear of soil, leaves and long grass, and check that water drains away rather than pooling. Where a post has rotted at the foot, it is often possible to cut out the decayed section and bolt a new length alongside in treated timber, but a post that is soft well below the ground line should be replaced properly — set deep, bedded firm, and left to settle before the gate is rehung.

Two sessions a year, an hour or so each, will cover it: a spring check of joints, clearance and drainage before growth takes over, and an autumn treatment of timber and ironwork before the wet arrives. Do that, and the gate will still be swinging sweetly long after the fence beside it has been replaced twice.
