24/7 Emergency Response Across Hobart
The flash floods of May 2018 served as a harsh lesson for Hobart, as the Hobart Rivulet breached its banks and water inundated properties from South Hobart to Sandy Bay. That kind of sudden water intrusion, followed by our cool, damp winters, creates the perfect conditions for hidden mould growth. In Tasmania, mould isn’t just a stain on the wall; it’s often a sign of a deeper issue, like trapped moisture in a sandstone foundation, poor sub-floor ventilation under a weatherboard cottage, or persistent condensation from the cold air that drains down from kunanyi/Mount Wellington.
At Water Damage Hobart, we provide technically precise mould remediation that is grounded in the globally recognised AS/NZS S520 Standard for Professional Mould Remediation. Our IICRC-certified technicians do not just wipe away visible mould. We find the moisture source, build engineered containment zones, and methodically restore your property’s structure to a condition that resists future growth. We work daily on homes across the region, from the Georgian sandstone cottages of Battery Point to the post-war brick builds in Glenorchy. We are available 24/7 because we understand the stress and worry that comes with property damage, and we know that in our climate, a fast, calm, and professional response is the first step to making things right.
What Is Mould Remediation in a Temperate Maritime Climate?
Mould remediation is much more than cleaning with household products. In Southern Tasmania, it is a scientific process designed to remove existing mould contamination while stopping airborne spores from affecting other areas of your property. As defined by the IICRC S520 standard, true remediation addresses both the visible mould and the specific moisture condition that allowed it to thrive.
This is especially critical in Hobart. A remediation method designed for a dry, hot climate will fail here. Simply opening windows during a cold, damp winter day can introduce more moisture into the home, feeding the very problem you are trying to solve. Professional remediation involves creating a controlled indoor environment, using commercial LGR (Low-Grain Refrigerant) dehumidifiers and specialised air movers. This forces dense, cold materials like double-brick walls and sandstone footings to release their trapped moisture, effectively breaking the cycle of mould growth.
Our Mould Remediation Process: Adhering to the AS/NZS S520 Standard
Inspection & Assessment
We begin with a detailed visual inspection, using calibrated moisture meters and thermal imaging cameras to trace the path of moisture. This is essential for discovering damp hidden inside wall cavities or within the sub-floor space of older homes, which is a common issue in Tasmania.
Containment Setup
To stop cross-contamination, we establish critical containment barriers using 6-mil polyethylene sheeting. We then create negative air pressure inside the work area, using HEPA filtration units to exhaust air outside. This ensures microscopic mould spores are captured and cannot drift into unaffected rooms of your house.
Safe Mould Removal
Our technicians, equipped with proper PPE, physically remove the mould. Porous materials that cannot be salvaged, such as contaminated plasterboard or saturated insulation, are carefully removed and bagged according to industry protocols. We then meticulously clean non-porous and semi-porous surfaces with industry-approved antimicrobial treatments.
Air Filtration & Decontamination
Throughout the remediation, industrial-grade HEPA air scrubbers operate continuously. These machines capture airborne mould spores, dust, and other microscopic particles, effectively "scrubbing" the air and improving the indoor environment.
Moisture Correction & Prevention
This is the most crucial step. We identify and document the source of moisture, whether it’s a burst pipe behind a wall, a leaking roof flashing, or systemic rising damp from inadequate damp-proof coursing in a heritage property. We provide clear, actionable recommendations to ensure the underlying problem is resolved for good.
Final Verification
After our work is complete, post-remediation verification (PRV) is performed to confirm the success of the project. This can involve a final visual check, moisture content readings to confirm dryness, and optional third-party air or surface sampling to provide independent assurance that the area is safe to reoccupy.
Specialised Mould Services for Hobart Homes & Businesses
We offer a complete range of mould services tailored to the specific building challenges found in Southern Tasmania.
Mould Inspection
A musty smell or a patch of discolouration on a skirting board is often just the tip of the iceberg. Our inspections go further, using tools like the FLIR E8 thermal camera to find temperature differences that show hidden dampness behind walls. We use non-invasive moisture meters to check saturation levels in materials common to Hobart properties, from the bluestone footings of Battery Point cottages to the timber frames of homes in Moonah and New Town. This data allows us to precisely define the scope of the problem.
Mould Testing
We can organise air and surface sampling to identify the types and concentrations of mould spores present (e.g., Aspergillus, Stachybotrys). This is often required for insurance claims, rental disputes, or when occupants have specific health concerns. Post-remediation verification testing by an independent hygienist provides unbiased proof that your property has been returned to a normal fungal ecology.
Mould Removal and Cleaning
This is our primary service, where we apply the full IICRC S520 protocol for physical mould removal. This includes removing heavily contaminated materials and performing a detailed cleaning of the remaining structure. For example, many older homes in South Hobart and Sandy Bay affected by the 2018 floods required removal of lower wall plasterboard and specialised drying of the exposed double-brick and timber structures before any rebuilding could start.
HVAcC and Duct Mould Cleaning
Poorly ventilated sub-floors are one of Hobart’s most common causes of mould, musty odours, and rising damp. Our technicians are trained to work in these confined spaces, clearing debris, treating mould on joists and bearers, and installing mechanical ventilation systems to ensure constant air exchange and prevent moisture buildup. This is critical for protecting the structural integrity of Hobart’s many heritage and weatherboard homes.
IICRC-Certified & Experienced Mould Remediation Specialists in Hobart
Our lead technicians are certified by the Institute of Inspection, Cleaning and Restoration Certification (IICRC), the international body that sets the standard for our industry. We strictly adhere to the AS/NZS S520:2025 Standard for Professional Mould Remediation, ensuring our work is based on proven science and best practices. This isn’t a handyman service; it is a technical trade that demands a deep understanding of psychrometrics, microbiology, and building science. We are fully insured and hold a valid [your license number, e.g., QBCC] license, providing peace of mind and protection for our clients.

Frequently Asked Questions About Mould Remediation in Hobart
In Hobart’s cool and damp climate, mould can begin to grow on a wet surface like plasterboard or timber within 48-72 hours. During winter, when homes are often sealed up and condensation is high, this process can be even faster.
Yes, for many people it is. Exposure to mould can trigger allergic reactions, worsen asthma, and cause respiratory irritation. The Tasmanian Department of Health advises that people with existing allergies, asthma, or compromised immune systems are at greater risk. Certain mould types can also produce mycotoxins, which pose more serious health risks with ongoing exposure.
Yes, when it is performed correctly according to the S520 standard. Our use of critical containment and negative air pressure systems is specifically designed to prevent the spread of spores and ensure the safety of anyone in other parts of the building. For very large projects, or if a household member has severe respiratory issues, we may recommend temporary relocation as a precaution.
A small, localised problem (like mould on a bathroom ceiling from a minor leak) might be resolved in 1-2 days. A larger project, such as one involving drying a saturated sub-floor area after a plumbing failure, could take several days to a week. We provide a clear, detailed timeline after our initial assessment.
Yes, if the underlying moisture problem is not fixed. Simply cleaning the mould is a temporary fix. Our process focuses heavily on identifying and providing solutions for the moisture source, which is the only way to achieve a long-term solution. This is the fundamental difference between professional remediation and surface cleaning.
