Essential Fencing Repairs for a Smallholding Boundary

A boundary fence on a smallholding takes more punishment than most people expect. It holds back sheep that lean on it, cattle that rub against it, and ponies that test every gap for weakness. Add a winter of gales, a summer of dry ground shrinking away from straining posts, and the inevitable fallen branch, and you have a structure that is quietly failing long before it actually breaks. Walking the boundary regularly, and knowing what to look for, saves a great deal of time, money and heartache.

Start With a Slow Walk Along the Line

Before you touch a single tool, walk the whole boundary with your eyes open. Take the same route every time so you notice what has changed since your last inspection. Early morning is ideal, when the light is low and any sagging wire or leaning post shows up as a shadow against the sky.

Carry a notebook or make notes on your phone, and mark anything that needs attention by severity. A smallholding boundary is rarely one continuous fence, it is usually a patchwork of stock fencing, post and rail, hedging and the odd bit of temporary electric. Note which sections are which, because repairs differ enormously depending on what you are dealing with. Look particularly at corners, gateways, watercourse crossings and anywhere the fence changes direction, as these are where stress concentrates.

Checking Posts and Stays

Posts fail in predictable ways, and catching them early is far cheaper than replacing a whole run.

• Test by hand. Give every post a firm shove. A post that moves at ground level is already on its way out, even if it looks sound above the soil.
• Look for rot at the base. Wooden posts rot just below the surface, where moisture sits. Probe with a knife or a screwdriver. If it sinks in easily, plan a replacement.
• Check the lean. A post leaning with the lie of the land may simply need re-ramming. One leaning against the strain is a sign the ground has softened or the post is rotting.
• Inspect stays and struts. Diagonal stays at corners and ends carry the load of the whole run. If a stay has lifted out of its notch or rotted where it meets the ground, the corner will move next.

When you replace a post, put it back in the same hole if the ground is sound, but dig a little deeper and wider. Set it with well-tamped soil or concrete, and remember that a slightly thicker post than the original will last longer without costing much more.

Tensioning and Repairing Wire

Stock netting should be taut enough that you cannot pull it more than a centimetre or two between staples, but not so tight that it snaps in the first hard frost. Wires that have stretched after storm damage or livestock leaning will sag, and a sagging wire is an invitation to any animal that fancies its chances.

Re-tension in stages rather than all at once. Use a wire strainer on the horizontal wires and work along the run, pulling evenly. If a section has been badly stretched, it may be quicker to cut out the damaged length and join in a fresh piece using proper wire joiners or a figure-of-eight knot, then tension the new section back to the original line.

Check every staple as you go. Loose staples let wire move, and moving wire wears through galvanising and rusts far faster. Tap them home, but avoid driving them so hard that they crush the wire. On electric fencing, walk the line with a tester and look for shorting against grass, nettles or a fallen branch, which is the most common cause of a fence that suddenly stops working.

Patching Gaps Before They Widen

Animals find gaps. A fox, a badger or simply a heavy ewe can push through a hole the size of a fist, and once one animal has been through, others follow. Repair small holes straight away with a piece of matching netting wired securely to the existing mesh, leaving no sharp ends pointing into the field.

Beneath hedges and along ditches, gaps appear where the ground has eroded or where animals have scratched away the soil. Fill these with a short run of netting or a few well-driven stakes and rails, and consider adding a line of electric wire at nose height to discourage persistent rubbing. If a gateway is the weak point, a well-hung metal gate on solid hanging posts will outlast any makeshift barrier.

Working With Weather and Livestock

Timing makes a real difference. Ground is easiest to work in spring and early autumn, when it is neither rock-hard nor waterlogged. Frozen ground makes digging almost impossible, and a wet autumn means new posts may settle unevenly. If a storm has brought down a tree across the boundary, clear the timber first, then assess the fence underneath, as the damage is often worse than it first appears.

Keep the animals in mind throughout. Move stock to a safe field before you start, and never leave a gap open overnight, even for a few hours. If you must leave a temporary repair, make it obvious to yourself with a marker so it does not get forgotten. And once the job is done, walk the line again after the next big blow. A fence is never finished, only maintained, and a smallholding boundary rewards the person who checks it often and fixes it early.
