Mould removal and remediation in Melbourne
Mould remediation is the controlled removal of mould contamination and the moisture that feeds it. We contain the affected area, remove mould at the source, dry the structure and verify the result, so the problem doesn't come straight back.

Removing mould properly means fixing the moisture too.
Mould spores are in the air inside and outside every building. They only become a problem when they land on something that stays damp: a ceiling under a leaking roof, a wall behind a failed shower, a wardrobe on a cold external wall. Once established, mould spreads into plasterboard, timber, carpet, furniture, clothing and anything else it touches.
Wiping or spraying visible mould treats the symptom. Our remediation follows the ANSI/IICRC S520 Standard for Professional Mould Remediation, which centres on finding the moisture source, physically removing contamination under controlled conditions, and confirming the area is clean before you move back in.
We remediate homes, rental properties, apartments, strata common areas, offices, retail and industrial sites across Melbourne and Victoria.
Black mould removal.
Black mould is the name most people use for dark mould on ceilings, walls, grout and furniture. Colour alone doesn't tell you the species or the risk, so we treat it with the same care as any contamination: contain it, remove it properly and fix the moisture that let it grow.
- Where it shows upBathroom ceilings, window frames, wardrobes, behind furniture on cold external walls, and around leaking showers. Melbourne's cold, damp winters make it common in poorly ventilated homes.
- Don't scrub or dry-brush itDisturbing heavy growth releases spores into the rest of the home.
- Don't paint over itMould keeps growing under paint while the moisture remains.
- Colour isn't the riskHow much there is, what it grows on, what's causing it and who breathes the air matter more than whether it's black.
Commercial mould remediation.
Mould in an office, classroom, aged care room or shared hallway is a health and compliance issue, and the site usually has to keep running. We plan containment and the order of work around your operations, so the rest of the building stays in use.
- Offices, retail and warehousesStaged and after-hours works, with containment and HEPA air filtration keeping work areas separate.
- Schools, childcare and aged careWork planned around occupants, with clearance before rooms are handed back.
- Healthcare and hospitalitySealed work zones and documented clearance before areas reopen.
- Strata common propertyHallways, basements, roofs and plant rooms, reported to the owners corporation and insurers.
Signs you need mould removal & remediation.
- Black, green or grey spots on ceilings, walls, grout or window frames
- A musty smell that doesn't go away with cleaning
- Mould that returns after you've wiped it
- A recent leak, flood, burst pipe or roof damage
- Condensation running down windows and walls in winter
- Asthma or allergy symptoms that are worse at home or at work
Recognise any of these?Get it checked before it spreads. We'll find the cause.
Water damage becomes mould damage in 24 to 48 hours.
Every hour water sits, it spreads further into walls, floors and ceilings. Once mould grows, it affects the air everyone breathes, especially people with asthma or allergies.

Mould removal questions, answered.
Still unsure? Talk to a technician. Ask us anything.
How long does mould remediation take?
It depends on how much area is affected and how wet the structure is. A single bathroom ceiling is very different to a whole level of a building after a flood. We give you a timeframe in your written scope, and we keep you updated with readings as drying progresses.
Do I need to leave my home during remediation?
Often you don't, because the work area is sealed off with containment and filtered air. If the affected area is large, or someone in the home has asthma, a lung condition or a weakened immune system, we may recommend staying elsewhere until clearance. We'll tell you on the day.
Will the mould come back?
Mould returns when the moisture source isn't fixed. That's why every job starts by finding the cause, and why we tell you exactly what needs repairing, whether that's a leak, failed waterproofing, poor ventilation or subfloor damp.
Does home insurance cover mould removal?
It depends on your policy and the cause. Mould from sudden and accidental water damage, like a burst pipe, is more likely to be covered than mould from long-term leaks or condensation. Check your policy or ask your insurer. We provide the photos, readings and reports insurers ask for.
Can I remove mould myself?
Small patches on hard surfaces can often be cleaned with good ventilation and protective clothing. Get a professional if the area is large, keeps returning, has a musty smell with no visible source, follows water damage, or if anyone in the home has a respiratory condition.
Is black mould dangerous?
Any mould growing indoors can affect health. It can cause sneezing, coughing and wheezing and worsen asthma and allergies, and people with weakened immune systems or lung conditions are most at risk. Colour doesn't tell you how harmful a mould is, so extensive growth should be removed properly whatever its colour.
Why does black mould keep coming back on my ceiling?
Because the moisture is still there. Common causes are condensation from showers without a working exhaust fan, roof leaks, cold spots from poor insulation, or a leak from the floor above.
How much does mould removal cost in Melbourne?
It depends on how much area is affected, which materials are involved, what caused it and access to the area. We inspect first, then give you a written scope and quote before any remediation starts, so you know exactly what is being done and why.
Is mould cleaning the same as mould remediation?
Not quite. Mould cleaning treats what you can see. Remediation finds the moisture source, contains the area, removes contaminated materials and checks the result. Cleaning can suit a small patch on a hard surface; anything larger, recurring or after water damage needs remediation.
