How Much Does Mould Removal Cost in Australia?

$250 - $6,000

    How Much Does Mould Removal Cost?

    If you’ve spotted mould in your building, getting rid of it should be a top priority. Not only is mould unsightly – it can damage your home and affect your health. And because it can be difficult to remove, it’s a job that’s best left to pros. Mould removal typically costs anywhere from $200-3800, $45-90 per square metre, or $60-110 per hour.

    But before you start comparing prices, you’ll want to make sure that it is mould that you’re dealing with.

    Signs of Mould Buildup at Home

    Up to 50 per cent of Australian homes can play host to mould, which is why it is key that homeowners stay on the lookout for these signs of mould buildup: 

    1. A damp, musty smell near walls or coming from your A/C
    2. Clothing with spots that feel slimy or fluffy
    3. Strange-looking spots or patches on carpets or furniture
    4. Allergy flare-ups and persistent cough
    5. Warped, spotted walls
    6. Dirty tiles (especially in your bathroom)
    7. Condensation and past water damage

    If you notice one or more of these happening at home, it might be time to look into mould inspection costs.

    What Factors Affect Mould Inspection Costs?

    Size of the mould-infested area

    Smaller patches of furniture will cost less versus having to treat entire walls. This is because larger areas will naturally require more labour and longer use of special mould-removing equipment such as dehumidifiers and air scrubbers.

    Mould type and treatment plan

    The kind of mould you’re dealing with can impact mould remediation costs. Acremonium, for example, can be removed with a water and bleach solution. Alternaria is a type of mould that needs air testing and is best removed by a professional. Stachybotrys, also known as black mould, can be deadly and requires expert removal. The type of mould will also impact the treatment plan for your home. 

    Mould location

    How much mould removal costs will also depend on where the fungi are located in your house. Mould removal in hard-to-reach areas such as crawl spaces or ceilings will cost a bit more since it will require a little more effort. 

    Inspection and air testing

    In general, mould removal services will start the process with inspection and testing to determine what type of mould they’re dealing with. This may be costed out separately in their quote. For example, simple mould removal can start at $500, but inspecting and air testing can bump up the price to $1,000. 

    Damage costs

    You might have to replace mould-damaged structures or materials once the removal is done. For example, replacing damaged drywall can cost upwards of $250.

    How to Reduce Mould Removal Costs

    Getting mould removed isn’t cheap or easy, but there are things you can do to reduce the cost. 

    • First, you can regularly inspect your home for mould to catch it before it spreads. Check your walls during the rainy season, check under the A/C and water closets, as well as near pipes. 
    • Next, fight mould and mildew with a water and bleach solution. Use a mask and gloves when handling bleach and other strong chemicals, and NEVER mix bleach with ammonia. 
    • Finally, you can use online resources to canvass for the most affordable mould removal service in your area.

    What kills mould naturally?

    Downward Chevron
    Baking soda, bleach, and vinegar are some home remedies used to get rid of mould. But these should be applied with care since spraying may cause mould spores to get distributed around your home. You will also want to wear protective equipment such as gloves and a mask even when using these ‘natural’ mould-killing methods.

    Can mould be removed permanently?

    Downward Chevron
    The only surefire way to remove and prevent mould for good is to reduce the moisture in your home. This means fixing leaks immediately, wiping down wet areas, and improving ventilation in your home.

    What happens if mould is not removed?

    Downward Chevron
    If mould is not removed as soon as possible, you might experience health problems such as recurring allergies, persistent cough, skin irritation, and headaches. The mould will also spread, damaging your home and belongings. Because of this, you must seek the help of a mould remediation specialist as soon as you spot the signs of mould.

    How long does mould stay alive?

    Downward Chevron
    Mould spores can survive in the air indefinitely. However, they only become visible mould once they come into contact with wet, moist surfaces in your home. Note that you can’t use bleach to get rid of mould spores and that overusing this strong acid might cause more harm than good to your family’s health.
