We've been told that BASIX requirements have changed somewhere in between our contracts being signed and our DA being lodged. As a result of the changes, we now have to change 5 windows and a big stacker door to 'Comfort Tone' glazing.
We're currently waiting for our PCV to come back from estimating. Has anyone else had to do this to their windows and, if so, what sort of $$ should we prepare ourselves for??!!
