Air Tightness Testing
Air tightness tests use a fan operated blower door to assess how leaky your building is by measuring how many volumes of air your building leaks. For example, if you get 10 air changes per hour at 50 Pascals (ACH50), that means you are losing 10 times the volume of air in your house per hour and in effect, you are heating your house ten times an hour. In a recent study, it was found the average house in Australia measured to be 17 ACH50. For reference, since 2019, the Australian building code performance standards require an air tightness of 10 air permeability that converts to around 10 ACH50 in domestic situations.
Our standard service costs $1500 plus GST, it includes:
- Initial blower door test, measure initial ACH50,
- Examination of building with a thermal camera,
- Filling of gaps, with an aim to improve the initial ACH50,
- Energy assessment,
- Final blower door test and air tightness certificate, indicating your home's final ACH50.
We also offer stand alone blower door tests, with thermal imaging and certificate at a cost of $1100 plus GST, for the purpose of assessing air tightness for Passive House certification or during the construction phase of energy efficient homes.
These fees are accurate for houses under 4oo square metres. If your home is larger, please contact us for a quote.
Travel costs may be incurred if you are not around Launceston.
Mould and Condensation consultation
A site visit with a thermal camera to determine the cause of mould and condensation, a detailed report is provided:
- Pre inspection preparations of plans with topography GIS data and orientation,
- Examination of building with a thermal camera,
- In particular, areas of mould and condensation will be checked for integrity of insulation,
- Report provided.
These fees are accurate for houses under 4oo square metres. If your home is larger, please contact us for a quote.

Hygrothermal simulation and consultation
WUFI Pro is used to simulate the behaviour of water vapour in a building assembly, revealing areas where mould is most likely to grow, and where condensation may accumulate, using standard climate data for the location.
For locations with micro-climates, weather observations such as temperature, relative humidity, rain and wind data are gathered on site, solar radiation and cloud cover data is obtained from BOM.
Coming soon in 2025.
