Decking

About our decking range

Decking can turn an awkward patch of garden into a level place for seating, pots or a small garden building. The first decision is the material. Our wooden decking section covers pressure-treated timber kits in 45 footprints. The composite decking guide explains the lower-treatment alternative and its stricter fitting requirements.

Timber is the natural choice when you want warmth, repairable boards and the option to stain the surface later. Composite suits customers who would rather wash the deck than retreat it each year. Neither material excuses a weak base. Drainage, ventilation and joist spacing decide how the finished deck feels after several winters.

Plan the deck with the rest of the garden. A patio cover can shelter seating, while garden fencing adds privacy. You can also compare garden structures, garden furniture, sheds, summerhouses and garden rooms before fixing the final footprint.

Wooden or composite decking?

Decking sizes, handrails and planning

Our prepared timber range runs from 4x4ft to 20x20ft. The 45 footprints make it easier to match an existing patio or garden building. Optional two-side and three-side handrail layouts can protect exposed edges while preserving an open entrance.

Measure the available area, door swings, steps and nearby drains. Decking beside a greenhouse also needs enough clearance for glazing replacement and cleaning. Our greenhouse foundation comparison, ground preparation guide and installation mistakes guide explain the same base principles.

Frequently asked questions

• Is wooden or composite decking easier to maintain?

  Composite decking usually needs less routine treatment. Both materials still need cleaning and clear drainage around the subframe.

• What base does garden decking need?

  Decking needs a firm, level and well-drained support structure. Soft ground should be stabilised before any joists or modules are fitted.

• Can I put decking directly onto soil?

  No, untreated soil is not a dependable structural base. Prepare the ground and use suitable supports specified for the chosen system.

• Do I need handrails around a low deck?

  Handrail needs depend on height, access and exposed edges. Check local requirements and design safe steps before ordering the kit.

• How should I measure for a decking kit?

  Measure the usable footprint and every fixed obstruction. Include steps, doors, drains, furniture clearance and access for assembly.

• Does composite decking need expansion gaps?

  Yes, composite boards move as temperatures change. Use the board manufacturer's exact end gaps, edge gaps and joist centres.
