It very much seems like a cost-saving for the builder as 13mm is double the price of 10mm. I know there are 10mm plasterboards suitable for walls but isn't this going against the contract to substitute products without notifying the client? Thanks in advance! Hi bc89 You might want to consider whether or not the works breaches section 18B of the Home Building Act. It may or may not be a defect, depending on the particulars of your contract. You may want to reach out to a specialist construction lawyer in your area and let them examine your contract and other documents related to the build, so that they can advise you on possible next steps.
