Whirlybird Installation in Mullaloo, Perth

Dave works right across Mullaloo and the wider City of Joondalup. The suburb sits about 22km north-west of the Perth CBD — close enough that travel is always included in the quoted price, same as everywhere else in the metro.

At roughly barely a kilometre from the water, Mullaloo sits in the strongest part of the sea-breeze belt. The Fremantle Doctor arrives here first and hardest, which means a wind-driven turbine spins for more hours a year than almost anywhere else in the metro — and it is turning at full noise through the exact part of the afternoon your roof is at its hottest.

Most of what Dave works on in Mullaloo is 1970s brick and tile on generous blocks. Large ground-floor footprints are the defining feature of this era, and ceiling area is what drives unit count — a sprawling four-bedroom home from the seventies frequently needs four units where a compact modern two-storey needs two.

Generous eaves are the compensation. Intake is rarely the constraint on these houses, so the extraction you fit is the extraction you get the benefit of.

The usual answer in Mullaloo is 4 whirlybirds, $1,250 all up. Those big single-storey footprints put a lot of ceiling under one continuous roof.

Coastal — strong sea breeze

Whirlybirds or Solar Vents in Mullaloo?

In Mullaloo, wind-driven whirlybirds are usually the better value. The breeze is dependable enough that you are not paying for a solar panel to solve a problem you do not have — three turbines at $950 will typically out-perform one solar vent at $750 on a site this exposed.

The trade-off out here is corrosion, not airflow. Salt-laden air is hard on cheap roof vents, and the bearing housing is what goes first — Mullaloo sees a lot of units that have seized or rusted out well inside ten years. Dave fits quality units with marine-appropriate fasteners rather than the cheapest thing on the shelf, because the labour to install a bad unit is identical to the labour for a good one.

If your roof happens to sit in a wind shadow — hemmed in by two-storey neighbours or heavy tree cover — that changes the answer, and a solar vent becomes worth costing. Dave will ask about that before quoting.

How many units for a Mullaloo home? Large single-storey footprints mean three to four units is typical rather than two.

"Dave was punctual, professional and had our four whirlybirds installed within two hours. The upstairs bedrooms are noticeably cooler through the afternoon — wish we'd done it years ago."
