Garden & paint the fence.

A professional gardener or fencer ensures the wood is correctly prepared and treated, extending the life of your boundary by several years. This guide covers the essential steps, costs, and considerations for getting your garden woodwork back into top condition.

What Does the Work Involve?

• Site Assessment: Inspecting panels, posts, and gravel boards for structural integrity, woodworm, or "wet rot."
• Preparation: Removing algae, moss, and dirt using a stiff brush or light pressure wash, followed by sanding back flaking old paint.
• Minor Repairs: Re-securing loose slats, replacing rusted fixings, and filling small cracks with exterior wood filler.
• Protection: Masking off nearby brickwork, paving, and covering delicate plants or garden furniture with dust sheets.
• Application: Applying a minimum of two coats of high-quality fence paint, stain, or oil using brushes, rollers, or specialized sprayers.
• End-Grain Treatment: Ensuring the tops of posts and cut ends are heavily saturated with preservative to prevent water ingress.

Typical Costs

Total costs are primarily driven by the condition of the wood. If a fence has been neglected for years, the labour required for cleaning and sanding can often exceed the cost of the paint itself.

How Long Does It Take?

• Small Garden (4-6 panels): 4 to 6 hours, including basic preparation and two coats.
• Medium Garden (10-15 panels): 1 to 2 days, depending on the complexity of the trellis work or repairs.
• Large Garden (20+ panels): 2 to 4 days, often requiring a two-person team for efficiency.
• Drying Times: Most water-based paints require 2-4 hours between coats; oil-based treatments may need 24 hours.

DIY or Professional?

Painting a fence is a common DIY task, but it is physically demanding and time-consuming. Professionals have access to commercial-grade sprayers that provide a more even finish than a brush, particularly on rough-sawn timber.

While there are no specific "Part P" style regulations for fence painting, you must ensure that any chemicals used (preservatives or fungicidal washes) are handled safely. If your fence is higher than 2 metres, or 1 metre next to a highway, you may need to consult local planning rules before making structural changes.

Choosing the Right Tradesperson

• Check Insurance: Ensure they hold Public Liability Insurance to cover accidental damage to your (or your neighbour's) property.
• Waste Licence: If they are removing old fence panels, they must have a valid Waste Carrier Licence from the Environment Agency.
• Application Method: Ask if they use a brush or sprayer; sprayers are faster but require much more careful masking of nearby surfaces.
• Questions to Ask:
  • Do you include the cost of the paint in your quote?
  • How do you protect my plants and the neighbour’s side of the fence?
  • What happens if it rains halfway through the job?

UK Regulations

• The 2-Metre Rule: In most UK residential areas, fences in rear gardens cannot exceed 2 metres in height without planning permission.
• Boundary Ownership: Check your title deeds (T-marks) to confirm which fence you are legally responsible for maintaining.
• Party Wall Act: While usually for brickwork, it is good practice to notify neighbours if you are working on a shared boundary.
• Environmental Disposal: Paint tins and treated timber cannot be put in general household waste; they must be taken to a licenced recycling centre.

Common Problems

• Painting Damp Wood: Applying paint to wet timber traps moisture inside, leading to rapid rot and the paint peeling off within months.
• Overspray: Using a sprayer on a windy day can result in "paint mist" landing on cars, windows, or your neighbour’s prize roses.
• Ignoring the Bottom: Failing to treat the bottom edge of the fence where it meets the soil or gravel board is the most common cause of premature failure.
• Poor Colour Matching: Different batches of the same paint brand can vary slightly; a pro will "box" (mix) tins together to ensure a consistent shade.

Expert Tip: Always check the weather forecast for the 24 hours after the job is finished. A sudden British downpour on fresh paint can wash your investment straight into the flowerbeds.
