Mould Mates starts from $650, made up of a $200 callout fee plus $150 per sample, with a minimum of three samples, including GST. The total depends on how many samples your property needs, which comes down to the number of rooms tested and the size of the home.

We need need a minimum of three samples: one in a problem room, one in a comparison room, and one outdoors as a control. Larger homes, open-plan spaces, or more rooms of concern need more, because one sample covers roughly an average sized room. We confirm the number once we have talked through your situation.

An air sample tells you whether the spore count inside your home is elevated compared with outside, and which types of spores are present. It is read against an outdoor control sample so the indoor result is meaningful. It does not pinpoint the mould on its own, but it confirms whether there is a hidden problem and helps us know where to look.

An outdoor sample sets the baseline for the normal spore levels in your area, we call this “normal fungal ecology”, so your indoor readings can be compared against it. Without that control, an indoor number on its own does not tell you whether levels are actually high. The outdoor control is included in the minimum three samples.

Air sampling suits a musty smell with no visible mould, where you need to confirm whether there is a hidden problem. If you can already see the mould, treatment is usually the better first spend, and our mould treatment cost page will price that. Some people do both, and we will talk you through it when we call.
