DIY Mould Removal: When It’s Safe and When It’s Not

Not every mould problem needs a professional. But getting the boundary wrong — tackling something that should be professionally handled — can make the problem significantly worse and expose your family to concentrated mould spores.

When DIY Is Appropriate

• Mould on hard, non-porous surfaces (tiles, glass, metal)
• Area smaller than 1 square metre
• Surface-only growth (doesn’t penetrate the material)
• No musty smell suggesting hidden mould
• No one in the household has respiratory conditions

When You Need a Professional

• Mould on porous materials (plasterboard, carpet, timber)
• Area larger than 1 square metre
• Mould keeps returning after cleaning
• Musty smell without visible source
• Black mould present
• Anyone in the household has asthma, allergies, or immune issues
• Mould is in roof cavities, subfloors, or wall cavities

Understand the health risks before deciding. When in doubt, a professional inspection costs $150-$400 and gives you certainty. Get matched with qualified Adelaide specialists.
