My house was originally built in 1972, and the previous owner had done an extension at the front of the house. Wondering do we need to do asbestos inspection if we want to do some minor renovation (eg, freshen up the bathroom, replace the tiles etc). In the long run we may need to knock down an internal wall to expand the Kitchen. Is it best to do do the inspection now or before the major renovation? Or can I assume the previous owner had done it as they have done major extension?
