Questions about subfloor ventilation.
Will ventilation fix every moisture problem?+
No. Ventilation can improve airflow, but plumbing leaks, groundwater, drainage or building defects may also need to be corrected.
Why does subfloor moisture matter for termites?+
Persistent dampness can create favourable conditions for termite activity and timber deterioration, so moisture reduction is an important risk-management measure.
Can ventilation be added to an existing home?+
Yes, where there is suitable access and an appropriate installation layout. The number and position of units depends on the subfloor.
