Common Causes of Ceiling Mould
- Upstairs Leaks: Bathroom, kitchen, or balcony water seepage from unit above
- Roof Leaks: For top floor units, rainwater ingress through roof
- Pipe Leaks: Concealed plumbing running through ceiling
- Condensation: Temperature difference between ceiling and room air
- Poor Ventilation: Moisture trapped in ceiling corners
- Aircon Issues: Condensate drainage problems, cold spots

Ceiling Types & Treatment
Concrete Ceiling
Common in HDB. Requires proper surface preparation, mould killing, and anti-mould primer before repainting.
Plaster/Skim Coat Ceiling
May need repair if water-damaged. Damaged plaster must be removed and replaced.
False Ceiling
Gypsum boards may need replacement if water-damaged. Hidden areas above false ceiling must also be checked.

Frequently Asked Questions
Why is there mould on my ceiling?
Ceiling mould typically indicates water issues - either leaks from above (upstairs bathroom, roof), condensation from temperature differences, or poor ventilation trapping moisture. Identifying the source is crucial for permanent resolution.
Is ceiling mould dangerous?
Yes, ceiling mould can spread spores throughout the room. As heat rises, ceiling mould has optimal conditions for growth. Spores fall from ceiling onto beds, furniture, and are inhaled during sleep.
How do I know if ceiling mould is from a leak?
Leak-related mould often appears in specific patterns following water flow. It may have water stains, peeling paint, or soft/damaged plaster. Condensation mould is usually more diffuse and appears in corners or around vents.
Can I paint over ceiling mould?
Never paint over untreated mould. The mould will grow through new paint and the problem will return worse. Mould must be properly killed and removed before any painting.
