FIX THE AIRFLOW, STOP THE MOULD
Subfloor ventilation.
Mould needs moisture, and stagnant subfloor air lets moisture build. Properly designed subfloor ventilation keeps the space under your home dry — the single most effective long-term mould prevention.
PREVENTION THAT LASTS
Remediation without ventilation is a temporary fix
If the airflow problem that let moisture accumulate is not corrected, mould returns — it is only a matter of time. Older homes with blocked or undersized vents, extensions built over original vents, and low-clearance subfloors all trap damp air under the house.
We design and install mechanical subfloor ventilation systems matched to your home: measured airflow in, damp air out, running quietly on timers or humidity sensors.
- Airflow and humidity assessment of your subfloor
- System design matched to the space — not one-size-fits-all
- Quiet, energy-efficient fans on timers or humidity control
- Installed by technicians who understand mould, not just fans
- Measurable before/after moisture readings
HOW IT WORKS
Designed, installed, verified
01
Assess the space
We measure existing airflow, humidity and moisture, and identify where damp air is trapped.
02
Design the system
Fan capacity, intake and exhaust positions designed for your subfloor geometry and conditions.
03
Install
Clean installation with minimal disruption — typically completed in a day.
04
Verify
Follow-up moisture readings confirm the subfloor is drying as designed.
