Frequently Asked Questions

What are leaky buildings?

Leaky homes are houses that, due to poor design or incorrect installation of building materials, allow water to penetrate the building. The water is soaked up by the framing and due to the lack of a cavity system there is no air flow to dry the timber out. This in turn allows mould to grow on the timber which then rots. Houses that leak are most commonly built from the early 90s onwards. They are usually houses built using monolithic cladding systems and designs that include parapets, no eaves and cantilevered decks.

Are leaky homes dangerous?

  • Rotting timber can have a serious affect on the structural integrity of the building, with a special cause for concern with cantilevered decks.
  • The other is the health risk imposed on the occupants living in the house. The mould growing in your leaky home produces a substance called mycotoxins, these mycotoxins attach to the mould spores and can be inhaled, ingested or transferred by skin contact causing mucus membrane irritation, skin rashes, nausea and a dry, hacking cough. For more information on the health risks imposed refer:
