A bathroom fan that spins but does not extract is why the ceiling goes black every winter. FreshDuct cleans, tests and where necessary replaces exhaust fans so moisture actually leaves the room.
Fan running but the mirror still fogs for an hour? It is moving almost no air.
Most people assume an exhaust fan is working because they can hear it. Noise is not extraction. A fan with a loaded impeller, a crushed or disconnected duct, or a blocked external termination will spin exactly as loudly as a working one while moving almost no air at all — and the moisture it was supposed to remove stays in the room.
In Perth this matters most from May to September, the months in which 77.7 per cent of the city’s annual rainfall arrives. Houses are shut up, showers are hot, windows stay closed, and the only mechanical route for that moisture to leave is the fan. When it fails quietly, the result shows up as black spotting on the ceiling above the shower, on window reveals and in the corners of the room.
The other very common finding is a fan that extracts perfectly well into the wrong place. Discharging into the roof cavity instead of through an external termination simply relocates the problem — you get condensation on the underside of the roof, damp insulation and a mould issue in a space nobody looks at until it is significant.
Why Perth bathroom and laundry extraction matters most in winter.
Airflow, duct and termination — because all three have to work.
Dust, lint and soap aerosol build a felt-like layer on the fan blades and the grille, and that coating alone can cut airflow dramatically. It is the easiest problem to fix and the one most often missed because the fan still sounds normal. We strip and clean the impeller rather than wiping the visible grille.
Black spotting on a bathroom ceiling, on the cornice above the shower or around window reveals is almost always a ventilation failure rather than a cleaning failure. Treating the surface without restoring extraction guarantees it comes back the following winter.
A fan ducted into the roof cavity moves moisture out of the bathroom and into a space with no ventilation path. Through Perth’s wet months that produces condensation on the roof underside, damp insulation and roof-space mould. We check where the duct actually goes, not where it is assumed to go.
Flexible duct in a roof cavity gets crushed under stored items, kinked around obstacles, or pulls off the fan spigot entirely. Any of those reduces or eliminates extraction while the fan keeps running normally. We inspect the run and reconnect or replace as needed.
External vent flaps on the coastal strip corrode and seize, so they stop opening under fan pressure. A seized flap turns a working fan into a sealed box. On properties from Fremantle through Scarborough to Sorrento this is a routine finding.
Some fans are simply undersized for the room or too far gone to recover. We will tell you when cleaning will not deliver, and quote a correctly sized replacement rather than taking payment for a service that cannot fix the problem.

We remove the cover and strip the impeller, clean both properly, and inspect the full duct run and the external termination. Then we test that the fan is actually extracting rather than just turning — which is the step that separates a service from a wipe-down.
If the duct is crushed, disconnected or discharging into the roof cavity, we photograph it and quote correcting it. If the fan is undersized for the room or beyond recovery, we say so and quote a suitable replacement. What we will not do is clean a fan, collect payment, and leave you with the same mouldy ceiling next winter.
Book a Perth Exhaust Fan ServiceWe service exhaust fans across metropolitan Perth in houses, apartments and strata buildings. Apartment bathrooms through the CBD, South Perth, Victoria Park and Applecross are frequently internal with no window at all, which makes the fan the only moisture path and makes a quiet failure much more consequential.
In older housing through Subiaco, Fremantle, Guildford and Bassendean we often find original or retrofitted fans with improvised ducting, and on the coastal strip corroded external flaps are routine. Both are straightforward to correct once someone actually looks at where the duct goes and whether the flap opens.
Cleaned, traced and airflow-tested — not just wiped over.
We check actual extraction before touching anything.
Cover and impeller removed and cleaned properly, not surface wiped.
The run followed to find crushing, disconnection or a roof-space discharge.
External vent cleared and the flap checked for free operation.
Extraction confirmed after cleaning so the result is measured.
Repair or replacement quoted separately where cleaning will not deliver.

Exhaust fan work pairs naturally with these Perth services.
Because running and extracting are different things. A loaded impeller, a crushed or disconnected duct, or a seized external flap will all leave the fan sounding completely normal while it moves almost no air. We test actual airflow rather than assuming, and trace the duct to find which of those is happening.
Because moisture is not leaving the room during the months when it matters. From May to September, when 77.7 per cent of Perth’s rain falls, houses stay shut and showers are hot, so the fan is the only mechanical moisture path. If extraction has failed, the moisture condenses on the coolest surfaces and growth follows. Cleaning the stain without fixing the fan just resets the clock.
No. It should discharge through an external termination. Venting into a roof cavity relocates the moisture rather than removing it, and in Perth’s wet months that causes condensation on the roof underside, damp insulation and roof-space mould. We check where the duct actually terminates and quote correcting it where it is wrong.
Yes. Some fans are undersized for the room or too degraded to recover, and cleaning them will not solve the problem. We will tell you when that is the case and quote a correctly sized replacement, ducted properly to an external termination, rather than charging for a service that cannot deliver the result.
Yes. Internal apartment bathrooms through the Perth CBD, South Perth, Victoria Park and Applecross often have no window, which makes the fan the only moisture path and a quiet failure much more damaging. We service individual apartments and multiple units for strata managers, working carefully around common property.
Cleaned, duct traced, airflow tested and honestly reported. Repairs and replacements available. 7 days.
