It could happen if there's been a lot of rain, a delay in  the building process, or if timber has sat out in the elements for too long before being covered?  Mould, mould and more mould...what do you do if you find this?  Well - this episode will cover this important topic.  Firstly: relax...it might not be as bad as you think!  Discuss the matter with your builder.  Discuss your health and safety concerns.  Discuss your asset value concerns and implications that mould might have for building integrity.  This episode will cover what we recommend.  Document, document, document is really our best advice.  When in doubt: test, test, test.  Remember the principal way to deal with mould is: SOURCE REMOVAL.
