Leaky homes are primarily homes that were built during the 90's. Monolithic style cladding was often used with no cavity system. The insulation within the wall spaces would literally soak up any moisture like a sponge and hold it there trapped thus creating its own ecosystem of black toxic mould. It would then only be a matter of time before the structural timbers (some of which are totally untreated radiata pine) would start rotting. Around this time it was also fashionable to have homes built without any eaves which meant constructing internal hidden spouting. The internal spouting was often manufactured from inferior materials such as galvanised iron which simply corodes in a seaspray environment such as Auckland. I have also fixed up and come accross properties where fibreglass had been used for flashings and clearly not stood the test of time.

In this case we have used Hardies linear board over a vented cavity system.
