Wood rot or termites? Telling timber damage apart on a Ballarat house
Fungal decay is the timber pest most often found on weathered Ballarat homes. How it differs from termite damage and why both belong in the same report.
In short: In a damp, cool climate fungal decay is often the bigger threat to external timber. An AS 4349.3 inspection reports it alongside termites because both are timber pests.
Two kinds of timber pest
The standard for timber pest inspections covers subterranean termites, borers and fungal decay. On older Ballarat houses we record wood rot far more often than termite activity, mostly in places that stay wet.
Where rot starts
Bottom rails of windows, door thresholds, verandah posts, fascias under leaking gutters and weatherboards close to the ground. Paint that has failed lets water into the end grain and the timber softens from the inside.
How it looks different
Decayed timber tends to be soft, crumbly or cracked into small cubes, often with staining. Termite damage usually leaves timber hollowed along the grain with mud packed into the galleries. We probe gently and photograph what we find rather than breaking anything open.
Why damp weather matters here
Long wet winters with fog and frost mean external timber dries slowly. A board that would survive a few dry summers on the coast can rot within a few years here if paint and drainage are neglected.
What the report says
Each finding is located, photographed and described, with a note on whether it looks like maintenance or something bigger. Where rot has reached structural members such as posts or bearers, we flag it as significant.
What it does not do
We do not cut out timber to measure the extent of decay, and we do not price repairs. A carpenter or builder can scope the repair from the report.
