What is Fence Repair?

If you have a wooden fence around your property with proper upkeep and maintenance, it can last for up to 12 years if made of cheap, budget untreated timber.

However, if it is made of pressure-treated lumber, you can get up to 30 years or even more from your fence before you have to replace it!

The weather is the main culprit for damaging fencing and the need for fence repairs.

Heavy rainfall, snowstorms, harsh winds, and salt air can all cause degradation of your fence, or, in some cases, Other common reasons for repairing a fence may be vehicle damages, vandals or an insect infestation.

What Common Repairs Need to Be Carried Out?

• If your fence has wet or dry rot, remove the infected area using a saw. Then patch or replaced with new timber to prevent any of the rot from spreading.
• Rusted or popped nails sticking out of your fence need replacing asap to prevent them from causing injury to people or animals or snagging your clothes. This can be a quick fix.
• Sometimes your fence can sag or become wobbly due to dampness or other weather conditions. If this happens, you need to support the sagging area with a brace or tension rod and make a fencing repair immediately.
• Fence posts will often sag due to either the post itself, which has rotted or the hole it has been put into. If this is a problem for your fence, you should fill in the hole with crushed stone or concrete if the hole is too big for the post or replace the rotten post.

What Maintenance Should I Be Doing?

Fence maintenance by repairing a garden fence is the best way to avoid most problems. With only a few regular checks and using simple procedures to make garden fence repairs, your fence will continue to look pristine!

Wooden Fences

There are many types of wooden fencing, and due to the organic nature of wood, they can be susceptible to mould, rot and insects. Panels and posts can become loose over time due to windy conditions.

Metal Fences

Fences, such as chain-link and wrought iron, can be badly damaged by the weather. When not properly protected by paint, moisture will cause them to rust.

Other damage includes paint peeling and Damage from impact, causing bending and sometimes knocking the fence down completely.

PVC Fences

Very durable and strong, PVC fences will only need to have small cracks or holes repaired, which will only happen if the fence is very old.

Electric Fences

Used to control livestock, these fences can be damaged by the weather or hit by a hard object or animal.

The type of fence being fixed affects the cost. For example, a small hole in a wooden fence can be cheaply repaired as the wood cost to patch this is not expensive.

On the other hand, repairing a metal fence can be much more complex and time-consuming, pushing up the cost.

How to Repair a Fence

Just because a section of fencing is damaged doesn't mean the whole fence has to be replaced. Follow these fence repair tips.

Always repair fencing with the most rot-resistant timber you can afford. Pressure-treated timber is saturated with preservatives and lasts almost indefinitely, even when buried in the ground.

Rot is a fence's worst enemy. Posts improperly treated or set in concrete typically rot away at ground level. For a comprehensive article on how to concrete in a fence post, click here.

Inspect your fence at least once a year. When a problem occurs, correct it before the damage spreads.

Depending on how rotted the joint is, a rail that's pulled loose from one or more of its posts may be salvageable. You could mend the break with a 2x4 scrap or a couple of metal T-braces.

To repair a rail with a 2x4:

• saturate damaged areas and a 2x4 liberally with a wood preservative to prevent the rot from spreading.
• Support the rail with a cleat to make sure the rail is level, then fit a 2x4 underneath. Nail the 2x4 to the post with galvanised nails. Hammer a couple of nails down through the rail into the cleat.
• Caulk the top edge and sides of the repaired post to ensure no moisture gets in moisture.

To use galvanised T-braces in rail repair:

• Level and drill pilot holes into the post and rail.
• Secure the T-braces to the rail with galvanised screws.
• Caulk the joint.
• Paint the T-braces to match the fence.

If the whole rail needs replacing, dismantle that section of fence and rebuild it.

• Make 2x4 rails to fit along the tops of the posts.
• Measure and cut each rail individually, allowing for variations in the spacing of the posts.
• Position the ends of the rails tightly together.
• Nail rails in place using galvanised nails.
• Measure and cut the bottom rail to fit neatly between each pair of posts.
• Nail the bottom rails into place with galvanised nails were driven in at an angle through the fence post.
• Measure and cut the fence boards. They should be of uniform length.
• Nail the boards to a single side of the railings, leaving equal space between each one.
• Secure each board to the rails using galvanised nails at the top and two at the bottom.
• Dig around a loose post before re-filling it in with concrete.

If a post wobbles, find the cause before repairing it. Rotted or broken posts may be repaired with a pair of splints or replaced.

If the post seems strong but has come loose in its hole, a pair of stakes or a new concrete base can steady it. For a more permanent fix, dig out around the post, plumb it with temporary braces, and pour concrete around the bottom.

Using premixed concrete, stir and pour into the hole around the post. Periodically slice the concrete mix with a spade to eliminate air pockets. Mound the concrete around the base of the post to help shed water.

If you put in the time now to repair your fences, you'll save yourself a lot of time, money and effort by preventing any further damage.

As always, make sure you wear protective clothing if taking on any DIY project.

Cracks and Splits in Fence

It might look minor now, but a crack in your fence panels or posts could finish off your entire fence. Use waterproof glue designed specifically for wood and outdoor use.

Clean any loose debris out of the cavity. Put some glue onto your paintbrush and force it inside the split from the top-down. Make sure you coat it thoroughly, and it is a thick enough coat to hold everything together.

Use strong clamps to hold the split glued wood together and leave it to dry for several hours or, if possible, overnight. On removing the clamps, the glue will have to set properly, making a good seal.

Rotten Fence

If you notice your fence panels or posts are rotten beyond repair, they will need to be removed and replaced.

Detach the rotten piece from the healthy fence panels so you don't cause further damage to the structure.

Dig the base of the fence post out using a shovel. If it's set in concrete, you'll have to break into it. Clear out the hole of debris.

Your replacement post or panel needs to be the same size as the rotten one in order to fit perfectly into the hole already in the concrete. Coated the wood with a thick layer of wood preservative and allow it to dry thoroughly before placing it in the ground. This will prevent any more rotting.

Put the new post into the hole, and brace it temporarily. Then, pour in a new concrete footing around the base of the post. Ensure that the concrete slopes downwards as this will stop any water pooling at the base and eventually soaking into the fence post.

Use a waterproof seal at the base of the post with a waterproof filler added once the concrete footing has completely dried. Re-attach the rest of the fence structure. This should now be completely secured and fully protected from the rest of the season's harsh weather!

Wobbly Fence

If your fence has become wobbly, it's possibly due to the wood shrinking inside the concrete footing. Squeeze some waterproof filler into any of the gaps and allow it to dry, and it should stay in place.

If there is no concrete footing at your fence's base, add a support post next to the wobbly post in order to strengthen it. This second post should be a little thinner, as the wobbly post, but the same width. Drive the new post a few feet into the ground and then bolt the two posts together to strengthen the weaker post.

Leaning Fence

A leaning fence is also a straightforward fence repair. Detach the leaning posts or panels from any surrounding fence structures.

Dig up the post, breaking up the concrete and clearing it away. Reset the post into its former position, making sure that it is level. Brace it to keep it upright, and pour the new concrete footing in. When the footing has set, reassemble the fence using new galvanised nails, making sure everything is tight and strong.

• When undertaking any fencing project, ask for assistance.
• Always wear protective safety gear when necessary.
• If using concrete, wash your hands after use as wet cement can burn.
• Don’t allow concrete to dry on your tools. Clean it off with a stiff brush.

How Long Does It Take to Repair Fencing?

The time it takes to mend a fence depends upon the Damage you need to repair. Will a repair job sort the problem or is it time to bite the bullet and completely replace the fence? Replacing a fence completely will normally take just 1 – 2 days.

Keeping fences in good repair adds value to your property and increases the security of your property. If you have an electric fence surrounding your property, then electric fence repairs may take longer if they need to be undertaken by a qualified contractor.

Concrete footings used in the base of your fencing are an important element of your fence's integrity and strength. Because of this reason alone, it is important to take care of fence repairs quickly.

When fence posts have become loose, it is usually due to problems in the footing. Over time, footings can crack or move and often prove very difficult to repair. The best solution is often to replace the entire fence post and the footings.

If you have earth and gravel footings, simply dig out as much of the backfill as possible and then re-plumb the fence post. By backfilling and tamping the integrity of the fence post will be restored.

When posts have rotted beyond repair, they can be replaced with a new post using new footings in the same location. Sometimes, this project may threaten the rest of the fence's strength and integrity, and it will require lots of work. If this is what's happened to your fence, it may be better to reinforce the old post with another post or a partial post.

You repair damaged concrete posts by shoring up the fence on all sides of the broken posts. Place blocks beneath the rails. Any backfill should then be removed down to the bottom of the post. If there is a concrete footing, you should dig a new post hole next to the old one. The old fence post can then be removed an inch or two above the ground. Try to wiggle the post free of concrete and lift it out with the assistance of a helper.

Add gravel inside the base of the hole. Cut a new post from the bottom of the hole to around three feet above the ground. Then cut the top at an angle to help the post shed water. Set the uncut end of the post into the ground. Add more gravel into the hole, then tamp it down.

After mixing your concrete with a handheld concrete mixer, fill the hole with concrete. Once the concrete has set, remove any bracing or blocks you have used.

Projects such as fence post replacement and concrete footing replacement can be made much easier using concrete tools such as a concrete mixer. Make sure the concrete is mixed properly is essential. When concrete is not mixed properly, problems can result. Sometimes these problems will not show until much later.

Fixing a stretch of broken barbed wire fencing can be done be quickly! You will need:

• Fencing sleeves
• Crimping tool - (Optional)
• Heavy-duty pliers
• Gripple sleeves - (Optional)

Using a fence stretcher, pull together enough wire to repair the break. From each half of the wire, remove any barbs for about 6 to 8 inches. Slide each wire end through one gripple sleeve. They are inexpensive and available from many hardware stores or online.

To make the splice secure, separate both strands of the two-wire ends. Wrap each wire around the barbed wire. One strand is wrapped counter-clockwise around the wire.

The second strand is used to make a loop over the first wire before securing it in place. It is then wrapped in a clockwise direction several times over the barbed wire. The remaining loose ends should be cut off, and the same wraps should be made on the opposite side of the sleeve.

Building Regulations or Planning Permission Approval for Fence Repairs

  • it won't be more than two metres high (from ground level); or
  • if an existing fence, wall, or gate already exceeds the limits above, its height would not increase.
• No part of the site can be a listed building or fall within the area surrounding a listed building.
• No part of the fence, wall, gate or any other boundary involved will form a boundary with a neighbouring listed building or its curtilage.
