Top 7 Signs You Need Professional Mould Removal (Not DIY)
If one of these seven signs applies, DIY is either unsafe, ineffective, or both. An S$50 on-site assessment — deductible if you engage us — costs less than repainting the same wall three times.
Quick Answer
Call a professional when the patch is larger than about one square metre, when mould returns within weeks of cleaning, when there is a musty smell but no visible mould, when the surface is damp without an obvious leak, when anyone at home has asthma, eczema, allergies or is pregnant or immunocompromised, or when mould appears after a flood or ceiling leak. Below those thresholds a careful DIY clean plus a ventilation fix is reasonable.
Musty smell that returns within days of cleaning
Hidden colony behind the visible surface. DIY can't reach it.
Black patches larger than 1 m²
US EPA/WHO threshold. Above this, sealed containment is mandatory.
Family member has asthma, eczema, or is pregnant
Spore aerosolisation during scrubbing spikes 100–1,000× background.
Mould keeps returning to the same spot
Environmental cause is unfixed. Moisture meter + thermal camera finds it.
You can see mould but not where it starts
60% of inspections locate hidden sources DIY missed.
Signs of Stachybotrys ("black mould")
Slimy, dark green-black. Higher mycotoxin risk. Do not scrub.
Selling or renting the property
You need documentation. Professional inspection + warranty protects the sale.
