Wire fencing can break from storm damage, fallen brush or interference from wildlife. If your fence breaks, it's not doing the job of keeping livestock or pets on your property and it's exposing your land to invaders. Whether your fence is made from barbed wire or chicken wire, you need to repair the damage fast. Check your fence line often to make sure your wire fence is in good condition.
Dig a hole with a small shovel near the base of a splintered post. You will need to remove the post and replace it with another one. If you have spare fence post or old wood on hand, use that instead of buying a new piece of wood. Once you've dug out the ground near the broken post, grasp the post with your hands and pull it up.
Put on safety goggles. Remove the wire from the fence post. If you used a staple gun to attach the wire, remove the staples using a mini pry bar or back end of a hammer. If you used nails, pull the nails out with the split end of a hammer.
Sink your new post into the hole where the old post was and firmly tamp the soil back in place. Attach your wire to this new post using a staple gun or a hammer.
Cut through the wire on the posts that surround the damaged section using wire cutters. You'll be replacing that panel of wire with a new panel. Before continuing, make sure the rest of the wire fence is snug. Damage that caused a hole may have loosened other parts of your fence. If the wire is snug and you've identified the only poor patch of fence, proceed. If the wire is not snug, you will need to remove the staples, tighten the wire by tugging it back in place, and re-staple it.
Measure the distance between the two posts with a measuring tape. Cut a new length of wire to fill that gap, adding 2 inches extra on each side so you can attach the wire.
Hold the new wire up to the fence post. You may need an extra pair of hands to secure the wire at the top, midpoint and bottom with a staple gun.
Stretch the wire to the next post. Ensure that it's tight and even with the rest of the fence. Staple the wire to the second fence post using at least two staples per foot of fence post. Once the second side is secure, go back to the first post and add additional staples.
Always wear safety goggles when working with wire under tension. Many people have been blinded by snapping wire.
