The hardware does the work
When a gate stops behaving, the culprit is usually one of four small parts: the hinges, the latch, the wheels or the closer. Each has recognizable signs of wear, and most are cheap to fix if you catch them early. This article is about those parts, rather than the gate as a whole. For general cleaning and finishing, the basics are covered in the beginner’s maintenance guide.
Hinges
Hinges carry the entire weight of the gate and take the stress of every swing.
Signs of wear:
- squeaking or grinding
- a gate that drops or drags
- visible play when you lift the free end and feel the hinge move
- rust staining or flaking
- screws loose in their holes
Quick fixes:
- Tighten all screws. Replace stripped screws with longer ones that reach solid wood, or re-fill and re-drive.
- Clean and lubricate the pin and knuckle. Wipe off the excess.
- If hinge screws will not hold in the post, consider through-bolts or moving the hinge to fresh wood, depending on the post.
- Replace hinges that are bent, cracked or worn through. Choose a type suited to the gate’s weight and swing; gate hinge types compares them.
- In wet or coastal climates, corrosion-resistant hardware lasts longer.
Hinge placement matters. The top hinge takes much of the pulling force and the bottom hinge takes much of the pushing, so both must be secure.
Latches
A latch needs to engage, hold and release smoothly.
Signs of wear:
- the gate must be lifted or pushed to latch
- the latch bounces off the keeper
- rust or stiffness in the moving parts
- play between the latch and keeper
- a latch that holds only when the gate is closed gently
Quick fixes:
- First check that the gate hangs correctly. A dropped gate will never latch well.
- Clean and lightly lubricate the latch, unless the maker says otherwise.
- Move or slot the keeper a small amount to match the latch.
- Replace the latch if the spring is weak or the parts are worn. Gate latch types explains the differences between thumb, gravity and magnetic designs.
- For pool and play areas, a child-resistant latch and a gate that closes by itself are important safety features; check local rules and keep them in working order.
Do not bypass or tape over a latch that is hard to use. Find out why it sticks.
Wheels and support rollers
Wide gates, especially wood or steel, often rely on a wheel to take weight off the hinges.
Signs of wear:
- a wheel with a flat spot, crack or wobble
- a wheel that no longer touches the ground, or that scrapes
- a gate that drags on uneven ground
- squealing from the axle
Quick fixes:
- Clean out dirt and wrap-around debris.
- Lubricate the axle if the design allows it.
- Check the height setting. A wheel should carry some weight without lifting the gate unevenly.
- Replace worn or damaged wheels. Gate wheels discusses the options and where support rollers help.
- Level or fill ruts where the wheel travels.
On slide gates, the track matters as much as the wheel. Keep it clear and straight.
Closers and springs
Self-closing gates use springs, hydraulic closers or spring hinges, and they are valuable around pools, play areas and pets.
Signs of wear:
- the gate no longer closes fully
- it slams shut or closes too slowly
- the gate swings back the wrong way
- the closer leaks oil
- the spring is rusted or visibly stretched
Quick fixes:
- Adjust the tension as the manufacturer directs. Small turns make a difference.
- Replace tired springs. Take care, as springs under tension can hurt you. If you are unsure, ask a professional.
- Replace leaking hydraulic closers; they do not usually repair well.
- Check that the closer still pulls the gate fully into the latch.
Self-closing hinges and springs describe typical designs.
Drop rods and bolts
Double gates often use a drop rod or cane bolt on one leaf to hold it while the other latches. Keep the rod straight, clean the hole it drops into and replace bent rods. Drop rod covers their purpose.
A tip for finding problems early
Listen and feel. A squeak is a request for lubrication. A rubbing sound is a sign of misalignment. A latch that needs a shove has moved. Most hardware gives warning before it fails.
Parts worth replacing together
If one hinge is worn, the other probably is too. Replace them as a set so they wear evenly. If you replace a latch, check the keeper as well. When you buy parts, keep your fasteners suited to outdoor use so you are not putting new hardware on old screws that will rust.
When it is more than hardware
If you tighten and replace all the hardware and the gate still sags or fails to latch, look at the posts and frame. The article on common gate problems and the one on gate moving parts take up alignment questions. Automatic gate hardware, such as arms and sensors, is a job for the manual and a qualified technician.
