Coastal gardens — particularly along the Dorset coast, the Solent shore and around Bournemouth and Poole — face fencing challenges that inland gardens do not. Salt-laden air accelerates corrosion and rot, and exposed sites experience significantly higher wind loading than sheltered inland positions. Choosing the right material and design makes an enormous difference.
Material Choices for Coastal Fencing
Standard treated softwood fencing performs significantly less well in coastal conditions than it does inland. Consider these alternatives for better longevity.
- Hardwood timber: oak, western red cedar — far better salt resistance
- Powder-coated aluminium: will not corrode, excellent for coastal sites
- Marine-grade galvanised steel: strong, long-lasting, needs periodic painting
- Composite fencing: no corrosion, excellent coastal performance
- Stainless steel fixings: essential in all coastal applications
Design for Wind Exposure
Solid close-board panels act as a sail in high winds — coastal fencing should either use slatted designs that allow some wind through, or be on very substantial posts with deep concrete footings. A slatted design at 50% opacity is roughly equivalent to a wind-speed reduction of 50% compared to solid panels.
Maintenance in Coastal Areas
Coastal fencing requires more frequent inspection and maintenance than inland equivalents. Inspect annually for corrosion, rot or structural movement. Clean salt deposits from surfaces regularly and re-treat timber at shorter intervals than manufacturers recommend for inland applications.
