I have experienced mould in a rental.
a building biologist can help with testing.
PHJ Services at Burleigh can do rudimentary testing and offers other services by way of drying the place out etc . Ph: 0755207733
if you want more detailed testing for instance if you are experiencing health issues from the mould or need to prove to owners the seriousness of the situation then Ecolibria is the place to contact. 1300326542
There’s hundreds of thousand of species of fungi/mould, about 6 of them are toxigenic.
if you develop allergies (not experienced before) or out of season then there is a chance your mould is not the garden variety.
good luck and if you need more info regarding the health impact i can help with that.
