A practical comparison of timber and composite decking, including subframes, maintenance and garden levels. This guide is designed to help you have a better first conversation and make a more informed decision, not to replace assessment by an appropriately competent professional.

Timber offers a natural material that can be maintained and refinished. Composite can reduce routine finishing but varies considerably in quality, appearance and heat response.
Height, steps, doors, planting, drainage and sight lines should be considered together rather than treating the deck as an isolated rectangle.
No material outdoors is truly maintenance free. Composite normally needs less refinishing than timber but still needs cleaning and sensible care.
It supports the entire deck and controls stiffness, longevity, drainage and ventilation.
