Lancashire is one of England's most rain-soaked counties. Squeezed between the Irish Sea to the west and the Pennine hills to the east, the county receives some of the highest annual rainfall in England — particularly across the Forest of Bowland, the Ribble Valley, and the upland mill towns of the east. Even the coastal strip from Blackpool to Morecambe, while somewhat drier, faces persistent moisture from the Irish Sea and strong prevailing westerly winds that accelerate the degradation of any untreated outdoor surface.

Composite decking boards are the ideal solution for Lancashire homeowners. Made from recycled wood fibre and polymer, they are fully moisture-proof, frost-resistant, and require no treating, sanding, or staining from one year to the next — a critical advantage in a county where natural timber decking can show significant deterioration within two or three seasons. At Paving & Slabs Ltd, we supply a full range of composite decking boards with delivery across all Lancashire postcodes, in grey, black, oak, and teak finishes.

Composite Decking Boards Across Lancashire

Preston

Preston is Lancashire's county town and one of the North West's fastest-growing cities. A mix of Victorian terraces, interwar semis, and modern housing developments creates diverse demand for garden surfaces across the city. Composite decking boards are popular here for garden rooms, raised terraces, and outdoor entertaining areas that perform reliably through Preston's wet and changeable weather. Read our dedicated guide: composite decking in Preston. We also supply Indian sandstone in Preston for complementary paved surfaces.

Blackpool & the Fylde Coast

Blackpool's Irish Sea-facing position creates persistent coastal exposure — salt air, strong westerly winds, and high humidity all year round. This makes natural timber decking a poor long-term investment on the Fylde Coast. Composite boards are far better suited to the conditions in Blackpool, Lytham St Annes, and Fleetwood. Read the full local guide: composite decking in Blackpool. We also supply patio slabs in Blackpool and porcelain paving in Blackpool.

Blackburn & East Lancashire

Blackburn and the East Lancashire mill towns — Burnley, Accrington, Nelson, and Colne — sit against the Pennine foothills and receive some of the highest rainfall in the county. The combination of high moisture, cold winters, and frost makes natural timber decking a maintenance-heavy choice in this part of Lancashire. Composite boards are an excellent fit for East Lancashire's urban and semi-rural gardens. Read our local guide: composite decking in Blackburn. We also have a dedicated composite decking Blackburn page.

Lancaster & Morecambe Bay

Lancaster and Morecambe sit at the northern edge of Lancashire, where the Irish Sea's influence is strongest and winters are coldest. Morecambe Bay's tidal exposure creates salt air conditions comparable to any southern coastal location. Composite decking boards are an ideal choice for homes across Lancaster and the Morecambe Bay area, performing reliably in the face of salt, moisture, and frost with no annual maintenance required.

Chorley, Wigan & South Lancashire

South Lancashire's towns — Chorley, Wigan, Leyland, and Skelmersdale — sit at the interface between Lancashire and Greater Manchester. High rainfall, cold winters, and significant frost periods make composite decking the smart long-term choice over timber for gardens throughout this area. We supply paving slabs in Wigan for complementary outdoor surfaces.

Installation in Lancashire

DIY Installation

Our 10 tips for installing composite decking and guide to laying decking on soil cover the full DIY process. For Lancashire's sloped gardens — particularly in the Ribble Valley and Pennine foothills — a raised composite deck on a properly supported joist frame is an excellent solution for uneven terrain.

Subframe & Drainage for Lancashire's Rainfall

In Lancashire's high-rainfall environment, drainage is paramount. Use C16-grade treated timber or aluminium joists at 400mm centres, build a minimum 1:80 fall, and ensure clear airflow beneath the frame. On Lancashire's clay-heavy soils, a compacted gravel base beneath the joist frame significantly aids drainage. Finish edges with our composite decking corner trim to seal board ends against wind-driven rain.

Ongoing Maintenance

Clear debris and leaves regularly — particularly important under Lancashire's deciduous trees in autumn. Full care guides: cleaning composite decking, preventing fading, removing rust stains, and removing scratches.
