Mould removal in Melbourne
We assess the affected area and likely moisture source, then treat and remove visible mould from suitable surfaces. Your fixed per-room tier is confirmed after inspection and before treatment begins.
- Fixed prices from $590 per room - the price follows the size of the mould, nothing else
- Most rooms treated in 2-5 hours
- Low-odour HOCl antimicrobial treatment, with HEPA air filtration where needed
- ULV dry fogging for contamination that has spread beyond one patch

Why mould keeps showing up in Melbourne homes
Melbourne winters are made for mould: cold nights, closed windows and heating that pushes warm, damp air onto cold walls and glass. Add a slow leak, a bathroom fan that doesn’t quite cope or a south-facing bedroom that never sees the sun, and you get the familiar signs - black spotting in corners and on ceilings, a musty smell in one room, paint that bubbles or flakes.
Scrubbing it off with supermarket spray usually buys a few weeks. The colony’s roots stay in the surface, the spores stay in the air, and the damp stays in the wall - so it comes back. Professional treatment deals with all three at once.
When to stop scrubbing and call a mould specialist
- The patch keeps returning to the same spot after cleaning
- Mould covers a large section of wall, or has reached the ceiling
- You can smell it but can’t find it
- It appeared after a leak, flood or long spell of condensation
- Anyone in the household has allergies or asthma that flare up indoors - mould can aggravate both

Before and after our mould removal services
Mould removal, remediation or inspection - which one do you need?
The industry uses three words that sound interchangeable but aren't - and quotes vary wildly depending on which one a company actually means.
- Mould inspection - a 30-minute visit that maps where the mould is, how far it has spread and, crucially, where the moisture is coming from. You get a clear scope and a fixed price for the work. $100 for residential properties; free for corporate clients.
- Mould removal - treating and physically clearing the visible growth from walls, ceilings and other affected surfaces.
- Mould remediation - the full job: preparing and containing the area, filtering the air, treating the growth, fogging where spores have spread, and advising on the moisture problem so it doesn’t simply grow back.
Our Melbourne mould technicians do all three. Every booking is scoped up front, and remediation-grade steps - containment, HEPA filtration, ULV fogging - are built into the process wherever the job needs them, not sold as mystery extras.
How our mould removal works
- Walk-through and moisture check. The technician confirms every affected area, takes moisture readings and identifies the likely source - condensation, a leak, or poor airflow.
- Preparation and air protection. The work area is prepped and, where the job calls for it, HEPA air filtration runs while we work so disturbed spores are captured rather than spread.
- Antimicrobial treatment. Affected surfaces are treated with an HOCl-based (hypochlorous acid) solution that neutralises mould growth - low-odour, and far gentler on your home than harsh chlorine products.
- ULV dry fogging, where required. For contamination that has spread beyond a single patch, an ultra-fine mist carries the treatment to settled spores on surfaces you can't see or reach.
- Removal of the dead growth. Once neutralised, visible mould is carefully cleaned off all suitable surfaces.
- Prevention debrief. Before leaving, the technician walks you through what's feeding the mould and how to starve it - ventilation habits, humidity control, and any repairs worth making.

Rooms we treat - and what we look for in each
One flat rate applies to any room of a given mould size - a bathroom ceiling costs the same to treat as a bedroom wall.
What mould treatment can - and can't - do
Treatment neutralises and removes active mould growth. It is not a renovation, and it's fair you know the boundaries before you book:
- Stains can outlive the mould. On porous or painted surfaces, dark marks sometimes remain after the growth is dead. They’re no longer active mould - but they may need repainting to disappear completely.
- Some materials are too far gone. Where mould has deeply colonised soft or porous materials - crumbling plasterboard, rotted timber, saturated carpet underlay - replacement, not treatment, is the honest answer. We'll tell you at inspection, not after payment.
- We treat the symptom and diagnose the cause - repairs are separate. Fixing the leaking pipe, failed sealant or broken exhaust fan behind the mould isn't part of the service, but you’ll leave knowing exactly what needs fixing.
- If the moisture stays, mould can return. No treatment on the market changes that. Our prevention advice exists precisely so yours doesn't.

Before we arrive
1. Leave the mould as it is
No scrubbing or spraying before we arrive - the technician needs to see the full extent of the growth to size and treat it properly.
2. Clear a path to the problem
Move what you can away from the affected walls, corners and ceilings so every surface is reachable.
3. Give the room a break
Keep kids and pets out of the rooms being treated while we work, and have power and water available for our equipment.

- Homeowners - winter condensation, bathroom ceilings, that one cold bedroom. Treat it once, properly, and learn what’s feeding it.
- Tenants and landlords - in Victoria, rented homes must be free from mould and damp caused by or related to the building structure; where it is, it counts as an urgent repair. Whether a patch is structural or lifestyle-driven is exactly what a documented inspection settles - useful evidence for either side of a lease, and a natural pair with end of lease cleaning in Melbourne if you're moving out.
- Property managers - fixed per-room pricing makes quotes to owners simple: no open-ended “assessment” invoices.
- Offices, shops and commercial spaces - book a free 30-minute survey and get a scoped, fixed-price plan for the whole site.
