Routine Cleaning & Maintenance
Composite fencing requires little upkeep compared to timber, no painting, sealing or staining is ever needed. However, regular cleaning keeps the surface fresh and ensures that panels and posts continue to perform as intended.
How to Clean Composite Fencing (step-by-step)
Remove loose dirt and debris using a soft broom or brush.
Prepare a mild cleaning solution with warm water and standard washing-up liquid.
Scrub gently using a soft-bristle brush or cloth, working along the grain of the boards.
Rinse thoroughly with clean water to remove any soapy residue.
Allow to air dry naturally.
Additional Tips
Clean once or twice a year, or after heavy build-up.
For deeper cleaning, use a low-pressure washer (<1500 psi) held at least 30 cm from the surface.
Avoid solvents, bleach, or abrasive pads, as these may damage the finish.

Seasonal Maintenance Tips
Composite fencing is built to handle the elements, but a few simple habits will help preserve its appearance across the seasons.
Spring: Rinse away winter residue and dirt. Check all posts and fixings for stability.
Summer: A light wash will refresh the surface and remove pollen build-up. No need for paint, oil or varnish.
Autumn: Sweep away leaves and organic matter to avoid surface stains or mould.
Winter: Panels resist rot, warping, and frost damage. Use a soft brush to remove snow or debris if needed, avoid metal tools that may scratch the surface.
With routine, your composite garden fencing will maintain its original finish and structural integrity year-round.
Stain, Scratch & Mark Removal
Composite fencing resists most common stains, but if marks occur, they are usually easy to remove.
Mud or Grass Stains: Clean with warm soapy water and a soft brush, then rinse well.
Grease or Food Marks: Use a mild household detergent and wipe clean promptly.
Algae or Mould: Treat with a gentle biodegradable outdoor cleaner, avoid harsh chemicals.
Surface Scratches: Minor marks can fade naturally over time, light sanding along the grain may help.
Long-Term Durability & Colour Stability
Composite fencing systems are engineered for a lifespan exceeding 20 years, with minimal maintenance.
Natural Weathering: Colour may gently lighten in the first few months as panels settle into a stable shade.
UV Resistance: Built-in UV stabilisers protect against fading.
Structural Checks: Inspect fixings, posts and panels annually to ensure they remain secure and properly aligned.
