How do I maintain timber cladding on the exterior?

Timber cladding maintenance depends on the finish system: opaque (painted) coatings need recoating every 5–8 years with light sanding and one fresh coat; semi-transparent stains need refreshing every 3–5 years; natural/uncoated timber (e.g. larch, cedar) requires no coating maintenance but will silver/grey over time.

All cladding should be inspected annually for: loose boards, open joints, failed sealant, moss/algae growth, and any signs of decay at board ends or around fixings.
