Composite Decking in Newbury
Garden design, patios, planting and full landscaping across West Berkshire. Free surveys, fixed written quotes, tidy workmanship.
Newbury Landscaping designs and builds composite decking across Newbury and West Berkshire. We fit composite first and timber by request, for a simple reason: an English deck spends eight months a year wet, and composite boards don't rot, don't splinter and never need staining. On a shaded deck under trees, that's the difference between a surface and a maintenance hobby.
The board is only half the job, though. What decides whether a deck bounces, creaks or sags is the sub-frame — and that's where our quotes differ from the cheap ones. Every deck gets a fixed written price after a free design visit.

Composite against timber, honestly
Composite boards
Wood-polymer boards from established names — Millboard, Trex, Composite Prime — in solid or capped construction. No rot, no annual oiling, consistent colour, and modern capped boards resist the fading early composites suffered.
Softwood timber
The budget route: pressure-treated boards at roughly half the material cost, but committed to annual cleaning and re-oiling, and a 10–15 year life against composite's 25+.
Grip and shade
Textured composite boards keep grip when wet — worth having on north-facing decks that stay damp, where timber turns lethal without regular treatment.
Balustrades & steps
Matching composite or powder-coated aluminium balustrade, and boxed steps that tie the deck into the lawn or patio below.
The sub-frame is the real build
Under every deck we build sits either C24 structural-grade treated timber or, increasingly, an aluminium joist system. Joists go at 300mm centres for composite — not the 400–450mm that suits timber boards — because composite spans shorter distances stiffly. The frame stands on adjustable pedestals or concrete pads clear of soggy ground, with a weed membrane below and airflow designed in: a ventilated deck dries, a sealed one rots from underneath. On Newbury's sloping gardens a deck is often the cheapest way to create a genuinely level outdoor room over a drop that would cost far more to terrace in masonry.
Aluminium sub-frames add around 15–20% but remove the last piece of rot risk entirely — worth discussing on a deck you want to outlive the mortgage.
