Composite Decking

Premium composite decking installation in Buckinghamshire & Berkshire. Low-maintenance, slip-resistant, weatherproof decking. 25-year warranty. Free consultation & quote.

Transform your outdoor space with premium composite decking from Garden Rooms Online. We supply and install high-quality composite decking across Buckinghamshire and Berkshire — low-maintenance, weatherproof, and built to last for decades.

Why Choose Composite Decking?

Traditional timber decking needs regular staining, sealing, and replacing. Composite decking changes all that:

Zero rotting, warping, or splitting — engineered to withstand British weather
No staining or sealing required — just an occasional clean with soapy water
Slip-resistant surface — safe for kids and pets, even when wet
25-year warranty — built to last
Eco-friendly — made from recycled wood fibres and high-density polyethylene
Available in a wide range of colours and finishes — from warm oak to modern anthracite

Our Composite Decking Range

We offer two premium ranges:

Grooved Decking

Classic ridged finish providing excellent grip in wet conditions. Available in Charcoal, Stone Grey, Savanna, and Amazon. Ideal for garden paths, patios, and around hot tubs.

Scribed Decking

A smooth, contemporary finish for a more refined look. Available in the same colour range. Perfect for modern garden designs and rooftop terraces.

All our decking boards are 3.6m lengths, 138mm wide, and 23mm thick — commercial-grade, not flimsy DIY boards.

Professional Installation

We don't just sell decking — we install it properly. Our installation includes:

Full ground preparation and levelling
Heavy-duty composite subframe (not timber, which rots)
Professional concealed fixing system — no visible screws
Fascia boards and edge trims for a clean, finished look
Optional integrated LED deck lighting
Typical installation: 1-3 days depending on size
