If you’ve noticed mould or mildew around your home at all, it could be a sign of a more serious plumbing issue. Untreated mould or mildew can lead to a variety of problems, including structural damage to your home and health issues. In this blog, we take a look how to identify these two types of fungi, easy ways to get rid of them and how to prevent them from reappearing.

plumbing mould


Mould can be incredibly varied in appearance, coming in a variety of colours including grey, black, green, yellow, blue and even pink. By the time you notice mould, it is usually multiplying in large colonies, however this means that the mould spores have been circulating in the air for some time already. Different types of mould are associated with different problems (including health problems like respiratory trouble and sinus infections), so it’s important to have a registered plumber do an inspection, not only to identify the type of mould, but also to determine whether it is linked to an issue with your plumbing.

The most toxic types of mould and their associated health issues are:

Chaetomium – Fatal deep mycoses, brain abcess, peritonitis, cutaneous lesions, permanent DNA damage, Multiple Sclerosis, Lupis


Fusarium – Fusarium Keratitis

Penicillium/Aspergillus – Bleeding in lungs, sinus infection, sepsis

Stachybotrys – Coughing, wheezing, runny nose, irritated eyes or throat, skin rash and diarrhea


Mildew is similar to mould, and could be a sign of mould in its early stages. It is usually lighter in colour than mould (white or grey as opposed to black) and has a powdery looking texture. Mildew, like mould, is associated with damp environments, which is why it’s important to have a local plumber do an inspection to rule out any problems with drainage or leaking pipes in your home.

Removing and preventing mould

If you notice a mild case of mould in your kitchen or bathroom, it should be relatively easy to remove. Simply apply a store-bought chemical cleaner to the affected area or use a natural remedy like clove oil, tea tree oil or bicarb. If the mould is on a textured surface like grout it may be harder to remove and you may want to hire a professional cleaner in this situation. Ensure towels are properly spread out when hung out to dry, and use shower racks to store bathroom products to allow water to drain off them properly. If you have a shower curtain, you should regularly inspect it for signs of mould, or better yet, replace it with a glass door. Wipe down any damp areas once you’ve finished using them and ensure your whole house is properly ventilated (especially the bathroom and kitchen). Leave windows open whenever you can to promote airflow and if you haven’t got them already, install exhaust fans into your kitchen and bathroom.

If, after all this, you find you are still getting problems with mould, it may be time to call your local plumber in Melbourne. Your plumber will be able to determine whether the recurrent mould is due to a plumbing issue like a leaking tap or pipe, a blocked drain or a slow draining sink, poor ventilation or even flooding (from stormwater).
