Hornsby sits where suburban Sydney meets the bush. Federation and post-war brick homes line the older streets, apartment towers keep rising around the station, and plenty of properties back onto Berowra Valley or Ku-ring-gai Chase. That variety makes air leakage hard to guess, so we measure it. AirXpress Testing carries out blower door testing across Hornsby, Waitara, Asquith, Wahroonga and Pennant Hills.
A single test tells you how much outside air is getting in, and with a smoke pencil or thermal camera we can show you exactly where.
Why Airtightness Matters on the Upper North Shore
Winter mornings up here are noticeably colder than in the city, and older homes often lose heat through gaps nobody can see: around timber window frames, under skirting boards, through downlights and where pipes pass through walls. The heater runs longer and the house still feels draughty.
Bushfire-prone blocks add another reason to care. Sealing gaps around eaves, vents and openings is part of keeping embers out, and a blower door test helps confirm the work has actually closed them up.

What Happens During a Test
We fit a calibrated fan into an external doorway and bring the building to a steady pressure difference of 50 pascals. While the fan holds that pressure, we record airflow and calculate air changes per hour (ACH50) and air permeability, following AS/NZS ISO 9972.
- Most homes take one to two hours on site
- Leaks are traced room by room while the building is under pressure
- You receive a written report with results and photos of problem areas
Renovations, New Builds and Apartments
Testing is most useful at two points: once the walls are sealed but before plasterboard goes up, when fixes are still cheap, and again at completion to confirm the result. For apartment buildings near Hornsby station we can test individual units or a sample across floors. Larger commercial jobs may suit our building envelope leakage testing.
