Key takeaways
- Fixing a chain link fence means tightening loose mesh, straightening bent rails, and replacing broken sections so it stays sturdy.
- If you’re wondering how to fix a chain link fence, start by checking for sagging areas. Tighten them with pliers and extra tension wire.
- Leaning posts need to be reset in concrete or reinforced with support brackets before they collapse completely.
A busted chain link fence is an eyesore and a risk. A weak spot can let pets escape, invite trespassers, or make your whole yard look neglected.
Luckily, fixing it isn’t rocket science.
Whether your fence is sagging, leaning, or has holes in the mesh, you don’t need to replace the whole thing.
Most repairs are simple and require basic tools from any hardware store.
This guide walks you through seven easy fixes so you can get your fence back in shape without spending a fortune.
1 — Check for all damage before starting
Before you grab your tools, do a full inspection. The last thing you want is to fix one issue only to realise there’s a bigger problem lurking nearby.
- Walk along the fence and look for rust, loose fittings, or damaged posts.
- Shake different sections to see if they wobble too much.
- Check for missing tension wires, broken links, or gaps at the bottom where animals could squeeze through.
- Look for signs of impact damage — like dents from a fallen branch or vehicle.
If you only patch up the most obvious issue, the rest of the fence might still be weak. Fixing everything at once saves time in the long run.
2 — Tighten loose chain link mesh
Sagging chain link fabric makes your fence look terrible and weakens its structure. If the mesh is hanging loosely, tighten it before it gets worse.
Re-secure loose tie wires
Tie wires hold the mesh to the top rail and posts. Over time, they loosen or break.
- Use pliers to twist them tighter or replace missing ones with fresh ties.
- Space them evenly so the mesh stays secure across the entire section.
Pull the mesh tight again
If a large part of the fence is sagging, reattach it properly.
- Remove any loose tension bands using pliers.
- Grab the mesh with pliers and pull it taut.
- Re-secure it with new ties or move it higher on existing supports.
For serious sagging over long fences, install extra tension wire along the bottom edge. This keeps the mesh tight and prevents it from pulling away again.
If the mesh is stretched beyond repair, it may be time to replace that section entirely.
3 — Fix bent top rails without replacing them
A bent top rail throws off the whole fence. It looks bad, weakens the structure, and can lead to further damage. But unless the rail is completely crushed, you probably don’t need a new one.
Straighten minor bends
For small bends, try this:
- Place two wooden blocks on either side of the bend.
- Press down firmly until the rail straightens out.
- Repeat as needed, but don’t apply too much force or you’ll snap it.
Reinforce weak spots
If the rail is weakened but not broken, add support instead of replacing it.
- Slide a metal sleeve over the damaged area.
- Secure it tightly so it reinforces the weak spot.
This saves money while keeping the fence strong. If the damage is severe, though, replacing the rail may be the better option.
4 — Replace broken links in damaged sections
Holes in the mesh are a security risk. Whether caused by rust, weather, or an accident, damaged sections should be replaced fast.
Cut out damaged parts
- Use bolt cutters or wire snips to remove broken or rusted links.
- Keep the edges clean — jagged ends can be dangerous.
Weave in new material
- Get a replacement piece of chain link mesh that matches the size of your fence.
- Weave it into place, following the same pattern as the original mesh.
- Tie the ends securely so there are no open gaps.
If done correctly, this patch job blends in seamlessly and restores strength to the fence.
5 — Straighten leaning fence posts before they collapse
A leaning post is bad news. Left alone, it can pull the whole fence down. Fix it before it gets worse.
Dig around the base
- Remove dirt around the post to check the foundation.
- See if the concrete footing is cracked or if the post is simply loose.
Reset the post
If the post isn’t broken, reposition it properly.
- Push the post back into its upright position.
- Pour fresh concrete around the base for stability.
- Let the concrete set for at least 24 hours before applying pressure.
Fix a leaning post to stop the problem from spreading to the rest of the fence.
6 — Secure wobbly posts with added reinforcements
Even if a post isn’t leaning, it might still feel unsteady. A shaky post today is a collapsed fence tomorrow. Reinforce it now to avoid bigger problems later.
Add extra support
- Attach a metal brace to the post and anchor it into the ground.
- If the post sits loosely in its hole, pack gravel or additional concrete around it.
Prevent soil erosion
Loose or eroded soil can weaken posts over time.
- Fill in any gaps around the base of the post with packed dirt.
- Compact the soil firmly to prevent further shifting.
A solid post means a sturdy fence that won’t fall apart after the next storm.
Prevent future damage so you don’t have to keep fixing it
Once your fence is back in shape, keep it that way. Regular maintenance stops small issues from turning into expensive repairs.
- Apply a rust-resistant coating to protect against corrosion. If rust has already started forming, check out this guide on how to remove it.
- Check tension regularly — tighten anything that starts to loosen.
- Trim branches near the fence to prevent impact damage.
- Inspect posts after storms to catch issues before they worsen.
A little upkeep goes a long way. Spend a few minutes checking your fence every few months to save hours of repairs down the road.
Chain link fences are tough, but they’re not indestructible. Sagging mesh, bent rails, and wobbly posts happen over time.
Fortunately, most fixes are simple and don’t require professional help.
With a bit of effort and some basic tools, you can keep your fence sturdy, secure, and looking good for years to come.
Big repairs take time, tools, and patience. If that sounds like more trouble than it’s worth, let an expert handle it so you can avoid the headache.
