A new fence is a significant investment for any homeowner. But too often, we see quality timber rotting years before its time simply due to neglect. In the damp climate of the South West, wood is constantly fighting against moisture, mould, and UV damage.
At Joe's Fencing & Landscaping, we build fences to last, but a little annual TLC goes a long way. Here is our 5-step maintenance checklist to keep your boundary secure and looking great.
1. The "Wobble" Test
The most critical part of a fence is the post, specifically the point where it enters the ground. This is where rot starts. Once or twice a year, give your posts a firm shake. If there is movement:
- Timber Posts: The wood may have rotted at ground level. If caught early, you can install a Concrete Repair Spur (Godfather). This bolts to the good wood above ground and concretes into the soil, saving the fence without replacing the whole post.
- Concrete Posts: If these are wobbling, the concrete foundation has likely cracked. You may need to dig out around the base and add fresh Postcrete.
2. Fight the "Green Fuzz"
Algae and moss are not just unsightly; they are sponges. They hold moisture against the wood, preventing it from drying out, which accelerates rot.
The Fix: You don't always need a high-pressure jet wash (which can sometimes damage the wood fibres). Often, a bucket of warm soapy water and a stiff deck brush is enough. For stubborn grime, apply a dedicated fungicidal wash. This kills the spores to stop the algae coming back so quickly.
3. Clear the Bottom Board
Take a look at the bottom of your fence. Is soil, piles of wet leaves, or grass piled up against the timber?
Wood needs to breathe. If the bottom board (gravel board) is buried in damp soil, it will rot rapidly. The Fix: Dig a small trench or clear the debris so there is a 20mm air gap under the fence. If your bottom boards are already rotting, replace them immediately before the rot spreads to the main panel.
4. Treat It (But Check the Weather)
Even pressure-treated wood loses its water resistance over time as the sun dries out the natural oils.
The Fix: Every 2–3 years, apply a quality wood preservative or oil. Pro Tip: Do the "Splash Test." Sprinkle water on the wood. If it beads up, it's fine. If it soaks in and creates a dark patch, it's time to re-treat. Wait for a spell of dry weather (at least 24 hours of no rain) before painting.
5. Tame the Ivy
We love greenery, but heavy climbers like Ivy or Wisteria are fence killers. Firstly, they trap moisture against the wood. Secondly, they act as a massive "sail" in the wind. A fence panel covered in thick Ivy weighs significantly more than a bare panel, putting massive strain on the posts during winter storms.
The Fix: Keep climbers trimmed back, or install a separate trellis structure so the plants aren't growing directly on the structural fence.
Too Little, Too Late?
If your fence passes the point of no return—where the posts snap or the panels crumble—it might be time for an upgrade. A professional install now saves money on endless repairs later.
