Is your fence looking a bit worse for wear? Over time, due to weather conditions and encroaching vegetation, it is common for flexible fencing to eventually sag, rust, or become misshapen. Beyond the unflattering aesthetic, a damaged fence no longer fulfills its role in terms of security or boundary marking. Before tearing everything down on a whim, you should evaluate whether renovation is possible or if a total replacement is inevitable. Here are the steps to effectively manage your old fencing.
Assessing the condition of the fence
Before undertaking any work, observe the structure carefully. If the problem is limited to a few loose tension wires, a simple tightening using the tensioners may be enough to restore stability to the whole unit. On the other hand, if the mesh has holes, if rust has attacked the core of the metal, or if the posts are moving in their footings, any repair will only be a temporary fix.
A fence that “bellies” (sags toward the ground) is often a sign that the posts are no longer plumb or that the braces have shifted. In this scenario, attempting to retension the mesh risks pulling the posts out completely. If more than 30% of the surface area is damaged, dismantling is necessary.
Can damaged fencing be repaired or concealed?
If the structure (posts and tension wires) is still sound, you can replace only the mesh roll. This is a cost-effective operation, but it requires patience to detach the old mesh from the wires. Be wary of the common misconception that installing a privacy screen will hide the mess: this is a bad idea.
Installing screening on old flexible fencing is risky. The additional wind load will exert enormous pressure on an already weakened structure, which will eventually blow the fence over during the first serious gust of wind. Only conceal a fence if it is perfectly tensioned and securely anchored.
How to properly dismantle your old installation
Dismantling must be done methodically to avoid injury and facilitate transport. Equip yourself with thick protective gloves, as old rusty metal is sharp and can carry bacteria (tetanus). Start by cutting the tie wires or staples holding the mesh to the tension wires using wire cutters.
Once released, roll the used mesh onto itself to form compact rolls, which are easier to handle. Next, cut the tension wires and remove the tensioners. For the posts, you have two options: either you manage to dig them up by breaking the concrete, or you cut them flush with the ground using a grinder if the footing is too deep.
Where to dispose of old fencing and posts?
Fencing, whether chain-link or welded, is made of metal (galvanized steel, iron). It must absolutely not be discarded in nature or in standard household waste bins. It is a waste product that can be easily recycled.
Take your rolls and posts to a recycling center, placing them in the bin reserved for scrap metal. If you have posts with concrete blocks still attached, try to separate them using a sledgehammer. Otherwise, ask the site attendant for advice, as the concrete/metal mixture (rubble/scrap) sometimes requires specific processing.
What should you replace your flexible fencing with?
Once the ground is clear, it is the ideal time to upgrade. If your budget allows, rigid panel fencing is the natural successor to flexible mesh. More aesthetic, much more robust, and maintenance-free, it immediately adds value to your property.
If you wish to stick with flexible options for economic reasons, opt for a professional-grade welded mesh (such as Jardingor or Axial). More rigid than traditional chain-link, it is easier to install and offers better durability over time, while remaining financially accessible.
The benefits of switching to rigid fencing
Replacing with rigid panels permanently solves the problems you encountered with your old fencing. The panels do not sag and are resistant to corrosion thanks to modern galvanization and powder coating.
Furthermore, unlike flexible options, rigid mesh fencing is designed to accommodate privacy systems (wood, PVC, or composite slats) without the risk of sagging, provided that the post installation recommendations are followed. It is a long-term investment that prevents you from having to redo the work in 10 years.
