Our builder has quoted us $4500 to upgrade our pine to upgrade to European House Borer resistant timber - Blue Pine..(They strongly recommend this)
Does this sound correct? Early responses would be appriciated as we either need to sign or the variaation or sign a disclaimer protecting the builder if we chose not to be upgraded..
Would it be cheaper to get the standard option and treat later? I have done a Google search and we are not building in an affected area - it seems to be more about where the pine is coming from...
