Indoor Mould Cleaning Brisbane – Mould Assassins
Assess. Infiltrate. Exterminate.
At Flood Responders & Mould Assassins, our indoor mould cleaning Brisbane service is designed to do more than simply remove visible mould. We locate the source, treat the contamination, and address the conditions that allow mould to grow. Our goal is to leave your home or workplace safe, clean, and protected against future mould issues.
Indoor mould is often a symptom of deeper problems such as hidden leaks, trapped moisture, or poor ventilation. We use advanced tools including thermal imaging cameras and moisture meters to detect mould activity in walls, ceilings, flooring and air-conditioning systems. This allows us to target the root cause with precision and deliver lasting results.

Why Indoor Mould Requires Specialist Attention
Mould spores thrive in damp, poorly ventilated environments. Bathrooms, laundries, kitchens, and rooms with inadequate airflow are common problem areas. Left untreated, indoor mould can affect air quality, cause damage to building materials, and impact the health of occupants. Our indoor mould cleaning Brisbane process goes beyond surface cleaning. We take a systematic approach:
- Assessment – Complete property inspection with detailed reporting and photographs
- Detection – Thermal imaging and moisture testing to identify hidden contamination and moisture sources
- Treatment – Safe, effective mould removal using environmentally friendly products suitable for humans and pets
- Prevention – Application of mould inhibitors and recommendations for improved ventilation and moisture control
- Restoration – Cosmetic repairs to restore the appearance and condition of affected areas
