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

Professional mould removal in Melbourne costs $650-$950 per room and takes two to five hours, depending on how far the mould has spread. Treatment neutralises the growth you can see and the spores you can't - but lasting results depend on finding the moisture that feeds it, which is where every one of our jobs starts.

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

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Removal of the dead growth. Once neutralised, visible mould is carefully cleaned off all suitable surfaces.
  6. 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

  • Mould on the ceiling corner above a tiled shower - bathroom mould removal
    Bathrooms

    Ceilings, walls, grout and sealant lines, window reveals; the highest-humidity room in the house.

  • Bedrooms

    Corners, window frames and the walls behind wardrobes and bedheads, where airflow is lowest.

  • Mould on a kitchen splashback wall beside the cooktop, under the rangehood
    Kitchens

    Walls behind appliances, around rangehoods and under sinks, where steam and slow leaks meet.

  • Mould growing low on a living room wall beside the sliding door to the garden
    Living and dining rooms

    External-facing walls, ceilings and the spaces behind large furniture.

  • Black mould in the ceiling corner of a hallway landing at the top of the stairs
    Hallways and landings

    Dead-air zones that condensation loves, especially in older Melbourne homes.

  • Mould spreading around a laundry window and ceiling above the washing machine and dryer
    Utility and laundry rooms

    Around washing machines and dryers, where warm damp air does its work.

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.

Mould help for renters, owners, landlords and businesses

  • 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.

Mould removal FAQs

Q: How much does mould removal cost in Melbourne?
A: $650 per room for a small affected area (around a window or in a corner), $850 where a large section of a wall is affected, and $950 where mould has spread across more than one wall or the ceiling. A 30-minute residential inspection is $100, and corporate surveys are free. Fantastic Club members can apply $60 of credits.
Q: How long does professional mould removal take?
A: Two to five hours per room. Small areas take around 2–3 hours, a heavily affected wall around 4, and multi-wall or ceiling jobs around 5.
Q: Can’t I just remove the mould myself?
A: Small surface spotting on tiles or glass can be a DIY job. Call a professional when the mould keeps returning to the same spot, covers a large section of wall, has reached porous surfaces like plasterboard or ceilings, appeared after a leak, or when you can smell it without finding it - those are signs the roots and the moisture source have outgrown the spray bottle.
Q: Do you remove black mould?
A: Yes. Colour doesn’t change the method: black mould gets the same inspection, containment, HOCl treatment and removal as any other visible growth. Note that on porous surfaces, dark staining can remain even once the mould is dead.
Q: Will the mould come back after treatment?
A: Treatment neutralises and removes the existing growth, but mould returns wherever moisture persists. That’s why every job ends with the technician showing you the moisture source and how to fix or manage it - deal with the damp, and the treatment lasts.
Q: Do you fix the leak or ventilation problem that caused the mould?
A: No - repairs aren’t part of the treatment service. What you will get is a clear diagnosis of where the moisture is coming from, so the right trade can fix it (or so you can manage it with ventilation and heating habits).
Q: Is the mould inspection free?
A: Residential inspections are $100 for a 30-minute visit that maps the mould, finds the moisture source and locks in your fixed price. For corporate and commercial clients, the 30-minute survey is free.
Q: Can you treat a rental property?
A: Yes - tenants, landlords and property managers all book this service. Victorian minimum rental standards make mould and damp a legitimate repair issue, so a documented inspection is useful evidence for either side.
Q: Why are there stains left after mould removal?
A: On painted and porous surfaces, mould can permanently discolour the material it grew on. Treatment kills and removes the growth; the shadow it leaves sometimes needs a coat of paint. You’ll be told at inspection if that’s likely.
Q: Do you use fogging, and is it extra?
A: We use ULV dry fogging when contamination has spread beyond a defined patch - it carries the antimicrobial treatment to settled spores across the whole space. It’s applied where the job requires it.
Q: Which Melbourne suburbs do you cover?
A: We cover Greater Melbourne - inner city, east, north, west and south-east, from Werribee to Ringwood and Epping to Frankston. The quickest way to check your address is to enter your postcode in the booking form: it confirms coverage and shows real availability instantly. Prices don't change by suburb - every room is a fixed $650, $850 or $950 based on the size of the mould, anywhere we service.
