Blower door testing · Adelaide & South Australia
A blower door test shows whether your building’s air barrier is actually working — and where air is getting through.
We test new builds, renovations and completed homes, locate the leaks and give you a written report your builder, assessor or certifier can use.
Residential testing from $880 incl GST. Written report and leak investigation included.
You do not need to know the testing terminology. Start with where the building is up to.
01 · Before plasterboard
This is the most useful time to test. We find leakage paths while the air barrier is still accessible, so your builder can fix them without pulling finished work apart.

Confirm the final airtightness result and receive the documentation required for your project, certification pathway or records.
I need a final test03 · Existing home or renovation
If you are planning renovation or air-sealing work, a baseline test shows where the home is starting and where the biggest leakage paths are.

At Willunga, the home measured 3.556 ACH50. The test traced major leakage to the sliding doors and the bathroom and laundry exhaust fans — even though dampers had already been fitted.
That is the difference between simply measuring a building and investigating it: you leave knowing where the result came from and what needs attention.

Testing and reporting follow ATTMA TSL1 and ISO 9972 methodology. Tell us before booking if the result is for Passive House certification or a specific compliance pathway so we can confirm the required scope.
01
We walk through the test boundary with you, close external openings and place the building in the correct test condition. For a pre-lining test, the air barrier needs to be complete and accessible.
02
We fit the calibrated fan into an external doorway, test across a range of pressures and investigate leakage paths while the building is depressurised.
03
We review what we found on site, then provide the measured ACH50 and q50 results with the written report required for the agreed test scope.

I’m Jono. I’ve spent more than 25 years working on buildings, first as a plumber and now across airtightness, ventilation and Passive House construction.
I will not just hand you a number. I will show you what the building is doing, where the likely problems are and what should happen next.
