Leaky Homes & Weathertightness
‘Leaky Homes’ became a huge concern for home owners through the 1990s and 2000s as more and more examples of poorly built homes that leaked to the point where mold and rotting timber endangered health and safety, not to mention the damage to owners’ financial well-bing.
There were several reasons for the disaster, the main ones being new, cheaper house designs using production materials such as untreated timber cladding and monolithic cladding that wasn’t installed properly or was improperly maintained, leading to homes that rotted, a housing boom that saw many unskilled builders building. The bad news is that leaky homes are still being built and that defects aren’t restricted to homes that leak. This page deals specifically with ‘Leaky Homes’, the causes and what to watch out for.
Be aware, all homes leak. It becomes an issue when the water is not dealt with and affects the integrity of the house. Modern designs, materials and construction techniques address many of these issues but there is still risk.
The best time to deal with weathertightness is at the design stage where different options can be considered and changes are easily made to the plans. It is important for the designer, builder and owner to look at the risks associated with the proposed building and reduce these to acceptable levels before building.
