What is the biggest maintenance risk for a timber home?

Moisture ingress is the single greatest risk to a timber home's longevity. Timber can tolerate brief wetting (rain during construction, occasional splash), but sustained moisture above 20% creates conditions for fungal decay.

Moisture ingress is the single greatest risk to a timber home's longevity. Timber can tolerate brief wetting (rain during construction, occasional splash), but sustained moisture above 20% creates conditions for fungal decay. The critical maintenance focus is therefore keeping water out: maintaining cladding coatings, clearing gutters, ensuring ground clearance, sealing around penetrations, and monitoring moisture levels in vulnerable locations (ground floor sole plates, around windows, at roof junctions).
