How to Maintain Your Garden Fence

Why Fence Maintenance Matters

South London’s rain, wind and occasional frost take their toll on garden fences. Without regular maintenance, wooden fences rot, warp and eventually collapse. A little care each year extends the life of your fence significantly and saves the cost of full replacement.

Annual Fence Inspection

Once a year, ideally in spring, walk along your entire fence line and check for:

• Loose or broken panels that rattle in the wind
• Rotten posts especially at ground level where moisture sits
• Leaning sections that may indicate post failure underground
• Missing or damaged gravel boards at the base
• Gaps where panels have shrunk or shifted
• Faded or peeling treatment that has worn off

Treating Your Fence

Fence treatment protects the wood from moisture, UV damage, rot and insect attack. Untreated fences can deteriorate in as little as two to three years.

Types of Treatment

• Fence stain — penetrates the wood grain, available in many colours from natural to dark brown
• Fence paint — sits on the surface, gives a solid colour finish
• Preservative — clear or lightly tinted, protects without significantly changing the appearance
• Creosote alternatives — heavy-duty treatment for maximum protection

How to Apply

1. Choose a dry day with no rain forecast for at least 24 hours
2. Brush off dirt, moss and cobwebs with a stiff brush
3. If the fence is very dirty, use a pressure washer on a low setting and let it dry fully
4. Stir the treatment thoroughly before use
5. Apply with a fence sprayer for speed, or a wide brush for precision
6. Work from top to bottom to catch drips
7. Apply a second coat once the first has dried if recommended

Repairing Common Problems

Loose Panels

Fence panels sit in slots in the posts or are nailed to arris rails. If a panel is loose:

• Check if the arris rails (horizontal support bars behind the panel) are intact
• Refix panels with galvanised nails or screws
• Add metal panel clips for extra security in exposed positions

Rotten Fence Posts

Rot usually starts at the base where the post meets the ground. If caught early, you can use a concrete post support (a metal socket driven into the ground) to reinforce or replace the rotten section without removing the whole post.

If the post is badly rotten, it needs full replacement. Dig out the old post, set a new one in postcrete or concrete and reattach the panels. Our landscaping team regularly replaces fence posts across South London.

Broken Gravel Boards

Gravel boards sit at the base of the fence and protect the bottom of panels from ground moisture. Replacing a cracked gravel board is straightforward and prevents the panel above from rotting prematurely.

Storm Damage

After heavy storms, check your fence immediately. Leaning or blown-down panels should be secured quickly to maintain boundary security and prevent further damage. Temporary props can hold panels in place until proper repairs are made.

When to Replace Rather Than Repair

Consider full replacement when:

• More than a third of the panels are damaged
• Multiple posts have rotted through
• The fence is leaning along its entire length
• Repairs would cost more than 60% of a new fence
