We have a private inspector. Everyone seems to use Darbecca, so we decided to join the crowd,
Will get Prepour, Frame, Pre-plaster and PCI inspections. Cost a bit over 2K for a double storey.
Have spoken to the Owner/builder you mentioned. Good idea to get friendly with him. You may need at some stage to ask him for some advice. He will also have contacts for doing things like driveway afterwards.
