Use this quick audit to spot humidity risks before they become expensive problems. Walk the route, record readings and implement fixes the same day.

Tools

• Access to drains for test-runs

Targets

• General interiors: 45–55% RH (acceptable 40–60%)
• Server rooms: 45–55% RH with stable temperature
• Pool/spa zones: use inverter models for quiet, steady RH

Checklist (15 points)

2. Cold external walls — condensation signs
3. Ceiling voids — hidden damp, blocked drains
4. Stores & archives — mould odour, packaging damage
5. Server/IT rooms — airflow paths unobstructed
6. Fitness/Wellness spaces — fogging on glazing
