A gate that swings sweetly on a Saturday morning and groans like a banshee by Wednesday is a very British problem. Our weather asks a lot of metal. Driving rain washes away whatever lubricant was there, damp air encourages surface rust, and grit thrown up from paths and driveways works its way into the joint. Add a few freeze-thaw cycles in January and even a well-made hinge will start to bind.
The good news is that hinge maintenance is one of the cheapest, quickest jobs in the garden. Fifteen minutes, a rag, a brush and the right lubricant will typically buy you another six months of silent, easy movement. Left alone, a stiff hinge doesn't just annoy you — it gradually works the screws loose, strains the gate post, and eventually drops the gate until it drags on the ground.
You cannot lubricate a hinge that is full of grit. Grime mixed with old grease forms a grinding paste, and that is what wears hinge pins out.
For gate hinges that lift off — the pin-and-cup type common on timber gates — take the gate down if you can. It makes cleaning and inspection far easier, and it is a two-person job at most. Lay the gate flat on a couple of offcuts of timber so you can see the whole hinge assembly.
This is where most people go wrong. A thin spray oil is fine for shifting a stuck pin, but it disappears within weeks outdoors. You want something that clings.
What to avoid? Cooking oil and general-purpose household oil. They gum up, attract dirt, and go rancid. Also resist the temptation to drown the hinge — a thin, even film worked into the joint with a small brush or an old syringe is far better than a puddle that collects grit.
Apply your chosen grease to the top of the hinge knuckle, then open and close the gate slowly several times. This draws the lubricant down through the joint. Wipe away the excess that squeezes out, because surplus grease becomes a magnet for dust and grass clippings. If the hinge has a grease nipple, use a grease gun and give it two or three pumps, no more.
Finish by lubricating the latch, the bolt and the catch plate, plus any spring or self-closing mechanism. A gate that swings freely but won't latch is only half fixed.
Lubrication is only part of the job. Give the gate a quick once-over while you have the tools out.
Aim for at least three lubrications a year: early spring after the worst of the wet, midsummer, and late autumn before the frosts. If you live on an exposed or coastal site, add a winter check. Autumn is also the ideal moment to clear fallen leaves from around the gate's swing path, since wet leaf litter holds moisture against the bottom rail and hinge.
Hinges are cheap, and there is no shame in replacing one. If the pin is deeply pitted, the hinge is bent, or it has developed more than a couple of millimetres of play, swap it. Choose galvanised or stainless steel replacements for outdoor use, fit them with the same fixing centres if you can, and grease them before you hang the gate. It is a half-hour job that will keep your gate quiet, easy to use and safely hung for years to come.
