Timber Side Gates: What Sydney Homeowners Should Know
Updated: Oct 6
The side gate is the hardest-working part of most Sydney fences. The bins go through it twice a week, the mower and the wheelbarrow go through it every few weeks, and tradespeople drag materials through it whenever anything gets done in the backyard. It is also almost always the first part of the fence to fail. That isn't bad luck — a side gate is a small, heavy, frequently loaded structure hung off one post, and the things that make it last are decided before it is built.
Work out the width from what has to go through it
Side access gets built to whatever gap is left over far too often. Before the posts go in, take a minute and list what actually needs to pass through: If the fence either side of that opening is being replaced at the same time, our side fencing in Sydney page covers that part of the job.
The wheelie bins, with a hand either side of them and room to turn at the end of the path
The mower, the wheelbarrow and anything else stored out the back
Building materials - sheets, decking boards, bagged product, a wheelbarrow of concrete
A trailer or a small machine, if the backyard is ever likely to be dug up or landscaped
A gate wide enough for a person and nothing else will be resented for as long as it's there. On tight terrace and townhouse blocks there may be no choice, but where there is a choice, a slightly wider opening costs very little at the framing stage and saves years of shuffling sideways.
The frame is what lasts, not the palings
A side gate carries its weight diagonally, from the top hinge down to the bottom corner on the latch side. Everything that stops it dropping is in the frame. That means a properly sized frame in durable timber, fixed at the corners rather than just nailed, and a brace running the right way.
The brace direction is the single most common DIY error. A timber brace works in compression, so it has to run from the bottom hinge corner up towards the top latch corner, pushing the far side up. A steel cable or turnbuckle works in tension, so it runs the opposite way, from the top hinge corner down to the bottom latch corner. Fit either one the wrong way round and it does nothing but add weight. We cover the diagnosis and the fix in detail in how to fix a sagging timber gate.
On timber choice, hardwood framing holds a screw and resists movement better than softer alternatives, and any timber in or near the ground needs to be rated for that exposure. The same reasoning we apply to fence posts and rails applies here, and our guide to timber paling fences in Sydney goes through the options.
Hanging on a post versus a brick pier
A gate post is not just another fence post. It takes the whole leaf weight as leverage, so it wants to be heavier in section and set deeper, in a proper concrete footing, with the concrete given time to cure before the gate is hung. Skimping here is what produces a gate that opens beautifully for a season and then starts catching on the path.
Where the gate hangs off a brick pier or a house wall instead, the fixings have to suit the masonry and the masonry has to be sound. An old pier with loose mortar or a hairline crack at the base will not hold a daily-use gate, however good the hinges are. It is worth having that looked at before the gate is made, not after.
Hardware for a gate you use every day
Side gate hardware gets used far more than driveway gate hardware, and it is usually where the money is best spent:
Hinges rated for the actual leaf weight, with adjustment left in them for the small amount of settlement every gate sees
Galvanised or stainless fittings, and stainless as a default anywhere near the coast - salt finds cheap hardware quickly
A latch at a height that suits the people using it, and that can be reached from both sides if that's how the gate gets used
A drop bolt or hold-open if the gate needs to stay put while things are carried through
Small detail, big difference: a gate that self-closes onto a stop rather than onto the latch itself will keep its alignment far longer.
If the gate forms part of a pool barrier
This is the one place where a side gate stops being a convenience decision and becomes a safety and compliance matter. Where a gate forms part of a swimming pool barrier, there are strict requirements covering self-closing and self-latching operation, latch height and position, and which way the gate swings. Those requirements are not something to work out from a hardware catalogue. Check the rules that apply to your pool with your council and the NSW Swimming Pool Register, and have the barrier assessed rather than assumed. Our pool fencing guide explains where this typically bites on existing fences.
Ground clearance, paths and drainage
Most side paths have a crossfall for drainage, and many have a step or a change of level partway along. A gate set to just clear the ground at the closed position can foul the path as it swings across that fall. Enough clearance to cope with the fall, without leaving a gap a small dog or a toddler can get through, is a judgement made on site with a level, not something to guess. Where the path is rough or the fall is severe, adjusting the path is sometimes the cheaper fix.
Finishing and keeping it working
Timber gates move with the weather, so the finish matters more than on a fence panel. Seal or oil all faces, including the end grain at the tops and bottoms of the palings and framing, and keep the bottom rail from sitting in wet grass or mulch. Then once a year, check the hinge screws, re-tension the brace or cable if it has adjustment, and clear the leaves out of the latch. Ten minutes a year is the difference between a gate that lasts and one that needs rebuilding.
Frequently asked questions
How wide should a side gate be?
Wide enough for the bins with clearance either side, and ideally wide enough for a wheelbarrow or a mower. Rather than working to a number, stand at the opening with the widest thing you regularly carry through and measure that, then add clearance. On narrow terrace blocks the boundary may set the limit, and then it's about making the most of what's there.
Should a side gate open in or out?
Usually inwards, so it isn't swinging over a footpath or into a neighbour's access. The path level, the fall and where the latch can be reached from all feed into it. Where the gate is part of a pool barrier, the swing direction is governed by the barrier requirements rather than by preference.
Can a sagging side gate be repaired, or does it need replacing?
It depends where the fault is. A racked frame or slack brace can often be pulled back and re-braced, and hinge problems are usually straightforward. A rotted bottom rail or a failed post footing is a rebuild of that element. Diagnosing which of the three is at fault is the first step - the causes look similar from a distance but need different fixes.
Hardwood or treated pine for a side gate?
For the frame, durability and screw-holding matter most, which generally favours hardwood. For palings, either can work depending on the look you want and how the gate will be finished. What matters more than the species argument is that the timber suits its exposure and that the frame is built and braced properly.
Can a new gate be matched to an existing timber fence?
Usually close, yes, though a weathered fence will never be an exact match for new timber until the new work has aged. Paling widths and profiles vary, so it's worth checking what's available against what's there before the gate is built.
Talk to us about side access
If your side gate is dropping, binding or simply too narrow to be useful, we build and hang timber gates across Sydney as part of our timber fencing and gate installation work - see our full fencing services and our overview of gates for Sydney homes, or our guide to Colorbond driveway gates if the front of the property is the problem. Get in touch for a quote and we'll look at the post, the path and the hardware before quoting anything.
