Unsightly mould growing on your walls and other surfaces is a massive frustration in many Australian homes.

Mould is a major problem in many Australian homes. The mould fungus is a silent fungal invader that can leave unsightly permanent stains on your home’s walls, panels, furnishings, clothes, and other belongings.

There are many types of mould but they all love damp, dark walls and will happily flourish on all types of wall materials given it has a moisture source. Mould is not fussy. Mould loves bathroom and kitchen walls, bedroom walls, walls inside cupboards and even garage walls.

It’s vital to get on top of any mould invasion as a routine part of your home maintenance. If you don’t deal properly with mould it can quickly mark and damage surfaces.

More importantly, mould is actually a sign of excessive moisture and so could indicate a major water leak in the roof or wall.

But remember mould’s favourite saying, “I’ll be back”.

Many people think a good old-fashioned mould cleaning remedy will do the trick but if you rely on that you risk missing the original cause of your mould problem.

Meanwhile the water continues to damage your home and the repair bill will continue to grow just like the mould. Mould is such a serious issue it can even lower the value of your home.

You see mould on walls in your home or garage it pays to call in the experts. Mould Cleaning Australia will not only remove the visible symptoms of a mould home invasion but they will also identify the root cause such as faulty ventilation or roof or plumbing leak.

The typical DIY approach will only touch the surface of your mould problem at best. It won’t identify the cause of the mould, or assess the air quality within the home and may even make your mould problem worse. So don’t let the mould take hold.

If you see mould on walls, call in the mould removal and remediation experts: Mould Cleaning Australia.  


Mould can grow anywhere there is moisture and organic matter. This usually happens when warm moist air comes into contact with a surface at a lower temperature, then the moisture condenses on to it.

What causes mould on walls?

Mould on walls is often the result of excess moisture in the air, it is a warning sign that there is a serious problem such as a condensation or water leak behind the wall. Remove/reduce moisture by not drying clothes indoors, heat your home to a constant and consistent temperature and keep furniture away from the walls.

To remove mould from walls try to reduce moisture by not drying clothes indoors, heat your home to a constant and consistent temperature and keep furniture away from the walls.

The most common causes of mould growth on walls are poor ventilation, leaks and dust. One (and probably the most famous) way to avoid it is to install ceiling and roof vents and dust walls where is necessary.

Mould on Walls & Ceilings

Mould loves hanging out on walls especially in corners, where furniture rests close against a wall, behind curtains or up near the ceiling. That’s because mould loves damp, dark places that lack ventilation.

Many walls never see the light of day and so mould can grow quite happily for a long time before being discovered.

That mould could be telling you there is a critical leak and if you delay calling in the experts it may prove very costly.

The Mould Cleaning Australia experts use precise tools to identify moisture content, temperature, humidity, dew point and particle count measurements to analyse the cause of the mould.

It means we can identify potential structural problems. But rest assured we’ll also let you know how best to fix these faults as well as removing all the existing visible mould and reducing over all air borne mould spores to be in line with fresh air from outdoors.

Mould Cleaning Australia uses an industry-leading two-step approach to black mould removal.

Our specially formulated fogging product eliminates all mould spores from difficult to reach wall areas so the mould won’t return as soon as turn your back. We use safe, tested processes to remove the mould from all walls including:

Mould can quickly damage painted surfaces and other delicate wall coverings so it’s important to act quickly. Most painted surfaces will not require repainting unless the paint is flaking or demonstrates substandard preparation and application techniques.


Mould on Windows & Doors

  • Mould loves to hang out on windows and doors as well. That’s because:
  • Water can gain entry to wall cavities thanks to poor window construction
  • Windows create condensation, which then drips onto window trims
  • Drapes promote mould growth on covered walls by trapping humid air
  • Permanently open doors encourage mould growth on the wall behind not allowing humid air to move from the area.

A build up of moisture such as condensation combined with poor ventilation means that mould can quickly grow on walls near windows and doors.

But mould growing on walls could indicate much more serious problems such as water damage from rising damp.

Our Mould Cleaning Australia technicians are trained to accurately identify the cause of your mould problem.

Our detailed mould remediation reports will outline any rectification steps you need to take to fix leaks or ventilation issues.

Then our tested mould removal products will quickly remove all mould and prevent mould returning.

Mould in Bathrooms & Kitchens Walls

Bathroom and kitchen walls are popular hiding places for mould thanks to the frequently damp, steamy atmosphere and poor ventilation. You’ll often find mould growing in the following places:

  • Walls and ceilings located over showers and baths
  • Tile grouting for kitchen splashbacks and wet areas
  • Behind doors or around window ledges

If there isn’t an issue with leaking plumbing then remedial action may involve installing adequate ventilation such as exhaust fans or other ventilation aids.

Mould Cleaning Australia technicians are accredited Goldmorr Master Technicians so you know your valuable kitchen and bathroom walls will get the treatment they deserve.

Our products and processes are so effective that we can offer a 12-month guarantee against the return of mould if you have followed all our recommendations.

Mould in Bedrooms Walls

Bedroom walls are prone to mould growth too. Bedrooms are often built on the cold sides of houses where condensation builds up and ventilation is often inadequate.

You really don’t want mould in your bedroom because you spend nearly a 3rd of your day in them. And although you might be sleeping during those hours mould certainly isn’t.

That mould is not only attacking your walls but it will soon spread into your clothes, furnishing and other belongings. You need to find out what’s causing your mould problem and deal with it once and for all.

We will prepare a comprehensive inspection report completely free of charge and obligation. We will identify the potential causes of your mould problem and outline any rectification action that is necessary.

The report will also outline how our Goldmorr Master Technicians will remove all mould and mould spores from your walls.

Our specially formulated products and industry-leading processes will deal effectively with all mould types. We will remove mould from ceiling cavities and other hard to reach areas.

The result; no more mould. You have our 12-month guarantee as an assurance that the mould won’t return (conditional on following our recommended remediation steps).

Mould Growth

Mould grows on almost any surface. Damp, poorly ventilated areas are prime growth areas for mould. Mould also loves porous surfaces that can’t be easily cleaned. Mould is a fungus and like any fungus, moulds form root systems that extend down into porous materials.

That’s why most home remedies won’t touch old mould stains. Moulds also spread very rapidly through airborne spores. These spores spread to other areas of the house and through your clothes and belongings where they form new mould colonies.

How to Get Rid of Mould Permanently?

You can find many DIY mould removal remedies on the web. But the problem with off the shelf or home style remedies is they are simply not very effective at getting rid of mould permanently.

These DIY solutions also don’t kill the mould spores hanging around waiting to start new mould colonies nor do they help you identify the real cause of your mould problem.

The only proven way to remove mould permanently is to use professional mould remediation services. The professionals from Mould Cleaning Australia will carry out an in-depth analysis of your mould problem covering the following aspects:

  • Measure moisture content
  • Temperature & humidity
  • Dew point and particle count
  • Infrared Analysis
  • Detailed visual inspections of areas prone to mould growth

This will allow us to locate potential structural problems. Our mould remediation programme uses safe tested processes to remove the mould from all wall surfaces without damaging paintwork or sensitive materials.

Our products have been tested in independent labs and are deemed safe for all wall surfaces including timber, gyprock, tile, and concrete. Our 12-month guarantee against mould returning gives you real peace of mind.
