WOW nearly 6 months since I last posted. So much has happened (ha ha).
We sent a letter to Induni asking what they were going to do about the mold - as winter is coming round again and there was not sign of anyone doing anything about the root cause (a cold bridge) ie bad design..
They have just replied basically saying it is our fault for not opening the windows enough during the last Christmas period (see other post about average temperature being -5)
