Ceiling Mould Treatment Brisbane – Mould Assassins
Assess. Infiltrate. Exterminate.
At Flood Responders & Mould Assassins, our ceiling mould treatment service is designed to completely remove mould from ceilings and prevent it from returning. Ceiling mould is often a symptom of hidden moisture problems such as roof leaks, poor ventilation, condensation build-up or water ingress from above. If ignored, it can damage plasterboard, stain paintwork, weaken building materials and release spores into the air you breathe.
Our trained team uses advanced inspection tools, targeted treatments and preventative measures to ensure the problem is eliminated at its source. Whether it is a living room, bedroom, kitchen or bathroom ceiling mould treatment, we provide a thorough and long-lasting solution.

Why Ceiling Mould Needs Specialist Treatment
Ceiling mould is not just a cosmetic issue. It is often an indicator of ongoing moisture problems. Common causes include:

- Moisture from air-conditioning units or exhaust fans

- Inspection – Comprehensive assessment using thermal imaging and moisture meters to locate the source of moisture
- Treatment – Application of safe, effective mould removal products that are environmentally friendly and safe for humans and pets
- Encapsulation – Where mould cannot be completely removed, sealing surfaces to prevent further spread
- Prevention – Applying mould inhibitors and recommending ventilation and moisture control improvements
- Restoration – Cosmetic repairs to restore your ceiling’s original appearance

Preventing Bathroom Ceiling Mould
Bathrooms are one of the most common areas for ceiling mould due to steam and high moisture levels. Our bathroom ceiling mould treatment service removes contamination and helps you maintain a cleaner, healthier space. To prevent mould from returning after treatment, we recommend:
- Ensuring exhaust fans are working effectively and left running for several minutes after use
- Keeping windows open during and after showers for better ventilation
- Repairing any leaks promptly
- Regularly wiping down and drying wet surfaces
- Maintaining insulation to reduce condensation build-up
