Weatherboard homes are some of the most charming in Australia, from Federation cottages to mid-century timber homes. But timber cladding and the construction methods of their era bring a particular set of things to watch for. Here's how to inspect one properly.
The cladding tells a story
Start with the weatherboards themselves. Walk the full perimeter and look closely at the timber, paying particular attention to the lowest boards where moisture collects, the timber around window frames where rot often starts, and the areas where downpipes meet the wall. Press gently on any suspicious sections: soft timber means rot. Look for paint failure, gaps at the joins, and boards that have cupped or split.
It's worth mentioning that not all "weatherboard" is timber. Many homes have fibre cement cladding (also called fibro or Hardiplank), which looks smooth and uniform with no wood grain, sounds hard and hollow when tapped, and is common on homes from the 1980s onward. It doesn't rot but can crack. If the home was built before the 1990s, fibre cement and other materials of that era can contain asbestos, which is only a risk if disturbed, so it's definitely worth an asbestos assessment before any renovation.
What's under the house
Many weatherboard homes sit on stumps or piers rather than a concrete slab, which means there's a subfloor space underneath. This is one of the most important things to check. If you can safely look into the subfloor void (through a vent or access hatch) look for standing water or very damp soil, white fungal growth on the underside of the floor timbers, and vents that are blocked. Good subfloor ventilation is critical to preventing rot and termite activity.
If the home is on timber stumps, those stumps can rot, lean, or sink over time, causing the floors above to become uneven. Inside, walk the floors and feel for bounce, soft spots, or noticeable slopes, which can point to problems with the stumps or subfloor below.
Termites and moisture
Timber homes are more vulnerable to termites than masonry ones, so check skirting boards, door frames, and timber at floor level for mud trails, hollow-sounding timber when tapped, and small exit holes. Any signs warrant an urgent professional pest inspection before purchasing.
Check the lowest section of internal walls for damp and staining, look up at ceilings for cracks and water marks, and tap wet area tiles for the hollow sound that signals failed waterproofing or spot-fixing.
Outside and orientation
Look at the roofline from the street for sagging, and check the roof material and gutters. Note which way the main living area faces. North-facing is warmer and cheaper to run, and your phone's compass confirms it in seconds. Check the age of the hot water system, and on older properties look for a private power pole on the land, which is the owner's cost to replace.
What this doesn't replace
Careful inspection helps you choose which homes are worth pursuing. It doesn't replace a professional building and pest inspection, which is especially important for timber homes given the termite and subfloor risks. Always commission one before making an offer. Use your own inspection to decide which properties are worth that next step.
