I had an asbestos audit completed on my property in Perth by a licensed asbestos surveyor, as the house was to be demolished the council requested they complete an invasive audit. I couldn’t believe some of the building materials that have asbestos in them, from the vinyl tiles(yes all three layers!) to the damp proof layer material. I always thought it was just the fibro panels and fence! Hubby was also a little concerned by this as we have reno’d quite a few properties over the years and had no idea (GULP!). The company we used was Environmental site services, we were happy with the service and would use them again. Their details http://www.environmentalsiteservices.com.au
