Installing a Welded Wire Mesh Fence the Right Way From Start to Finish

Installing a welded wire mesh fence is well within reach of a competent do-it-yourselfer, but the difference between a fence that stands straight for decades and one that leans within a year comes down to preparation and patience. The mesh is rarely the part that fails; the groundwork is. This guide walks through the full process, from planning the line to tensioning the final panel, with the practical details that the instructions on the packaging tend to skip.

Planning the Line and Checking Boundaries

Before any tools come out, confirm exactly where the fence is allowed to go. Check your property boundary, and if the fence sits on or near a shared line, talk to your neighbour first to avoid disputes later. Look into local rules on fence height, since many areas limit how tall a boundary fence can be, particularly at the front of a property. If there is any chance of buried services such as gas, water, electricity, or telecoms, have them located before you dig, because striking a utility is both dangerous and expensive.

Once the line is agreed, mark it with a string line pulled tight between two end stakes. This string is your reference for everything that follows, and a few extra minutes getting it straight and level saves hours of frustration. Walk the line and note any slopes, drainage channels, or obstructions that will affect post spacing.

Setting Out and Spacing the Posts

Post spacing depends on the panel or roll system you have chosen. Rigid panel systems demand precise spacing because each panel is a fixed length, so measure carefully and mark each post position along the string line. For rolled mesh, spacing is more flexible, but posts placed every two to three metres usually give adequate support. Always begin by setting the two end or corner posts first, because these carry the most load and define the run.

Corner and end posts take more strain than intermediate, or line, posts, so they are often larger and set more deeply. Some installers add a diagonal brace or a strut on these key posts to resist the pull of tensioned mesh. Taking the time to make the corners truly solid pays off, because a fence that fails almost always fails at a weak corner first.

Digging and Concreting Post Holes

A reliable rule of thumb is to bury roughly a quarter to a third of the post in the ground. For a typical fence, that means a hole around two to three times the post width and deep enough to sit below the frost line in cold climates, since frost heave can lift a shallow post over a few winters. A post-hole digger or auger makes this far easier than a spade and produces a neater, narrower hole that uses less concrete.

Set each post in the hole, check it for vertical with a spirit level on two adjacent faces, and brace it temporarily with timber stays. Pour in concrete, working it to remove air pockets, and slope the top of the concrete slightly away from the post so water drains off rather than pooling at the base. Recheck the level after pouring, because posts love to shift while the concrete is still wet. Then allow the concrete to cure fully, ideally for a day or two, before hanging any mesh, since tensioning against green concrete can pull a post out of plumb.

Attaching and Tensioning the Mesh

With the posts set and cured, you can hang the mesh. For panel systems, lift each panel into place and fix it to the posts with the supplied brackets or clips, keeping the top line level by eye against your string. For rolled mesh, attach one end firmly to an end post, then unroll along the line, keeping the mesh upright and roughly in position as you go.

Tensioning rolled mesh is what gives a fence its taut, professional appearance and its resistance to sagging. Pull the mesh tight along the run, using a fence puller or a length of timber clamped to the mesh for leverage, before securing it to each intermediate post. Work from one solid end post toward the next, and resist the temptation to fix the middle first, as this traps slack you cannot later remove. Staple, clip, or tie the mesh at the top, middle, and bottom of each post for even support.

Dealing With Slopes and Corners

Sloping ground is where many DIY fences look untidy. There are two main approaches. Stepping keeps each panel level and creates a stair-step profile along a slope, which suits rigid panels and gives a crisp look. Raking, or following the contour, angles the mesh to match the slope and suits flexible rolled mesh, leaving no triangular gaps at the base. Choose based on your material and the steepness of the ground, and decide before you start rather than improvising mid-run.

At corners, make sure the corner post is braced to handle pull from two directions. Carry the mesh fully into the corner so there is no gap, and overlap or join sections neatly so the join is not the obvious weak point of the fence.

Finishing, Gates, and Final Checks

Close the bottom gap that animals and intruders exploit. Depending on your needs, you can bury the bottom edge of the mesh, fit a bottom rail, or peg the mesh down at intervals. Trim any sharp wire ends and treat freshly cut ends with cold galvanizing paint to stop rust starting at the cut. If the fence includes a gate, hang it on the strongest posts you have, since a gate concentrates load and use every time it swings.

Finally, walk the whole line and inspect it. Push on the panels to confirm the posts hold firm, check that the mesh tension is even, and look for any low points where the base lifts. A fence
