Tips for Identifying Mould in the Household

 Identifying danger zones for mould is relatively easy, although directly locating the growth can be challenging. Any suspicions of flooding or water damage should be investigated as soon as possible. Water staining, condensation, and discolouration on the walls, floors, and ceilings are telling signs that mould may be present. Walls that are bulging, bowed, or warped are also strong indicators that moisture has penetrated them, and is likely settling at the visible damage points.

 

Once you have located mould, there are some basic visual cues you can look for to distinguish the strain and severity of the problem. Mould comes in a variety of colours. Many homeowners are relieved to find that harmless salt deposits known as effloresence are often confused for white mould. Pink mould, known as aireobasidium, typically thrives outdoors, but can trigger a variety of allergies when present in the home. Yellow mould known as serpula lacrymans is usually found around wood, where it feeds and causes the fibres to dry-rot away. Finally, blue or green mould, known as penicillium, spreads very quickly and can cause allergic reactions, chronic sinus infections, and act as an irritant to the lungs.

Regardless of the colour or type of mould you have identified, action should be taken immediately. Any visible mould likely indicates the presence of a mould colony hidden from sight. Even the smallest patch of mould will spread, and finding any traces means your home has the right conditions for its growth. This information is meant to enhance your consultation with a professional.
