Heavy Bathroom Mould Growth

Heavy bathroom mould caused by exhaust fan and paint that was inadequate.

PRE-INSPECTION

• Heavy mould growth to ceiling, cornice and walls.
• Exhaust fan is inadequate and not extracting air efficiently.
• Ceiling, cornice and walls are porous due to inadequate paint work.
• Moisture readings for ceiling suggest ceiling is absorbing moisture from steam.

OWNER RECOMMENDATIONS

• Upgrade exhaust fan to a model that extracts a min of 280m3 of air per hour.
• Paint ceiling, cornice and walls using a mould inhibitor additive or wet area paint.
• Leave exhaust fan running for additional 20 mins after use particularly during the winter months.

TREATMENT
Anti-microbial treatment to all mould growth designed to penetrated the substate and kill the mould at the root source.

CONCLUSION
The owner followed my recommendations and the work carried a 6 mths warranty.
