Fixing musty, damp underfloor spaces in Batemans Bay, Moruya, Narooma and along the Eurobodalla coast - fans, vents and moisture barriers that actually solve the problem.

This stretch of coast gets some of the highest annual rainfall in NSW, and homes tucked in against the escarpment around Malua Bay and Surf Beach often sit in damp, shaded ground for long stretches. When vents get blocked by landscaping, retaining walls or decking, that moisture has nowhere to go, and it condenses under the floor, feeds mould, and eventually softens the bearers and joists. Subfloor ventilation work restores that airflow with extra vents, mechanical fans, and moisture barriers over exposed ground.
Multi-fan systems that pull moist air out and push fresh air through, wired to a discreet switch or humidistat. A single fan runs $800-$1,500 fitted; a full multi-fan system for a larger home is usually $1,500-$3,000.
Cutting in new brick or timber vents, replacing corroded coastal vents, and unblocking vents covered by retaining walls, decking or garden beds. Typically $50-$150 per vent supplied and fitted.
Heavy-duty polythene sheeting over exposed subfloor soil to stop ground moisture rising into the timber, particularly useful on shaded, high-rainfall blocks around Malua Bay and Surf Beach. Around $15-$25 per m2 including installation.
A crawl-through with a moisture meter and torch to check vent coverage, timber condition and mould before it becomes structural. $150-$300, often credited back against recommended work.
The Eurobodalla coast gets significantly more rain than most of the NSW coastline, and many blocks around Batemans Bay, Malua Bay and Surf Beach back onto bush or escarpment that keeps the ground shaded and damp for days after rain. Older homes here often have vent placement designed for a drier assumption than the area actually gets.
It's also common along this stretch for retaining walls and terraced gardens - needed on the area's sloping blocks - to have covered original vents without anyone realising, since the change happens gradually over several landscaping projects.
