Installation and replacement

A new exhaust fan, installed right, from $250 complete

Like-for-like replacements, brand-new installations in rooms that never had a fan, timer and humidity-sensor upgrades – sized to the room and ducted properly to the roof or eave, so the steam actually leaves your house instead of touring it.

From $250complete like-for-like replacement, fan included. Typically $280-$480. New locations $550-$1,200.

Sound familiar?

When installation is the right answer

Tick two or more and it is time to book — every one of these gets worse, never better, on its own.

The old fan is worn out, loud, and repairing it costs almost as much as replacing it
The bathroom has no fan at all – just a window you never open in July
Your fan vents into the roof cavity, quietly feeding mould above the ceiling
The current fan is far too small for the room and always was
You want a quiet fan – the old one sounds like a light aircraft
You want it to run on a timer or humidity sensor instead of relying on memory
The ensuite or laundry was renovated and ventilation was an afterthought
A pre-sale or rental compliance check flagged the ventilation

Why Perth bathrooms and kitchens behave differently

Perth adds a factor most cities do not: salt. Coastal air corrodes the metal parts of an exhaust system – motor housings, fixings, and especially the backdraft damper at the discharge. A seized, corroded damper is one of the most common causes of both the flapping noise and the lost airflow we find in suburbs near the coast.

Perth’s long hot summers also mean bathrooms and laundries get used hard with the house shut up against the heat, while limestone and brick construction keeps interior surfaces cool enough to condense steam. Extraction that leaves the building is the fix; recirculating the same moist air around the house is not.

What a proper installation includes (and shortcuts we refuse)

A fan screwed into the ceiling is not an installation – it is a decoration. A proper job sizes the fan to the room’s volume, wires it safely through a licensed electrician, and ducts the discharge all the way to the roof or eave so the moist air leaves the building.

The shortcut we will not take: venting into the roof cavity. It is the cheapest path and the most expensive mistake – it relocates your bathroom’s moisture into the one space you never inspect, where it condenses on timber and insulation and grows mould you cannot see. Every FreshDuct installation discharges outside. No exceptions.

Where wiring and ducting already exist, a like-for-like replacement is quick: from $250 as a complete supply-and-install job, typically $280 to $480 depending on the fan you choose. A brand-new location – new wiring, new duct run, new discharge point – generally runs $550 to $1,200 as a complete job, quoted firm before we start.

Choosing the right fan for the room

Size beats brand. Extraction capacity is measured in cubic metres per hour, and the fan must match the room: a powerful ensuite fan is wasted in a toilet, and a toilet fan in a family bathroom is why the mirror never clears. We calculate it from the room, not from what is on special.

Controls do the remembering. A run-on timer keeps extracting for the minutes after your shower when most of the moisture is still airborne. A humidity sensor switches the fan on before the mirror fogs and off when the room is dry – the set-and-forget answer for kids’ bathrooms and rentals. Both can be added to a fan you already own, and both remove the one variable no fan can control: whether anyone remembers to switch it on.

We install ceiling and wall models, inline fans for long duct runs, quiet low-sone units for bedrooms-adjacent bathrooms, and 3-in-1 heater-fan-light units – all major Australian-market brands.

Made simple

Where the air goes: right vs wrong

Ducted outsideSteam leaves the building
The right way. A duct carries the moist air from the fan all the way to a roof or eave discharge, so it leaves the building entirely.
Vented into the roofMoisture condenses on the timbers
The shortcut we refuse. A fan that dumps into the roof cavity has not removed the moisture – it has moved it somewhere you never look, onto cold timber and insulation.

What you actually get

What a proper installation includes

The difference between a fan that is mounted and a fan that works is almost entirely in the parts you cannot see.

Included as standard

  • Extraction sized to the room, calculated from its actual volume – not whatever was on the shelf
  • The full duct run to a roof or eave discharge, so the moist air leaves the building
  • Wiring done safely, and any new circuit or switch handled by the right trade
  • Old unit removed and taken away, with the new one fitted to the existing opening wherever sizes allow
  • Timer or humidity sensor fitted if you want the fan to stop depending on memory
  • The discharge point sealed and weatherproofed at the roof or wall
  • Real extraction tested before we leave – not just switched on to prove it spins
  • A firm quote first, and a time estimate you get before the job, not after

And the things we will not do

  • Discharge into the roof cavity – not once, not to save an hour, not on any job
  • Fit a bigger unit than the room needs so the invoice looks better
  • Leave the old fan or the packaging behind for you to deal with

Installation questions, answered before you ask

How much does exhaust fan installation cost in Perth?

Like-for-like replacement – where wiring and ducting already exist – starts from $250 as a complete supply-and-install job and is typically $280 to $480 depending on the fan. A new location, with new wiring and a duct run to the roof or eave, generally runs $550 to $1,200 complete. You get a firm number before any work starts.

Do I legally need an exhaust fan in a bathroom without a window?

Bathrooms need ventilation – natural or mechanical. No openable window means mechanical extraction is the compliant path in practice. If you are renovating, selling or leasing, this is one of the cheapest compliance items to get right.

Why does it matter where the fan vents to?

Because a fan that dumps steam into the roof cavity has not removed the moisture – it has hidden it above your ceiling, where it condenses on cold timber and breeds mould out of sight. Every FreshDuct installation ducts to the roof or eave so the air genuinely leaves the building.

Can you replace my fan with a quieter one?

Yes – low-noise units are one of the most common upgrade requests. If your current fan is audible from the bedroom, a modern quiet unit is a genuine quality-of-life improvement for a like-for-like price.

What is a humidity sensor fan and is it worth it?

It switches itself on when the air gets moist and off when the room is dry – no one has to remember anything. For kids’ bathrooms, rentals and anyone who showers before dawn, it is the single best upgrade per dollar in this category.

Do you install kitchen rangehoods too?

Yes – including ducting recirculating hoods to the outside, which transforms how well they clear smoke and smells. Details on our kitchen rangehood page.

What happens to the old fan and the hole it leaves?

We take the old unit away, and the new one is fitted to cover the existing opening wherever the sizes allow. Where a ceiling patch is genuinely needed we tell you at quote time, not once the old fan is already out.

Can you do a whole apartment block or unit development?

Yes – multi-bathroom and multi-unit installations are a specialty, with scheduling around tenants and documentation for strata and owners corporations. See our commercial and strata page.

How long does an installation take?

A like-for-like swap: usually one to two hours. A new location with wiring and ducting: typically half a day. Either way you get a time estimate with the quote and photos of the finished work.

Which brands do you supply?

All major brands sold in Australia. We spec the fan to the room’s extraction needs first, then offer options at different price points within that spec – never the reverse.

My renovation is mid-flight – when should the fan go in?

Talk to us before plaster goes up: running ducting and wiring is dramatically cheaper with the ceiling open. We happily coordinate timing with your builder.

Is there a warranty?

The fan carries its manufacturer warranty and FreshDuct backs the workmanship – if something we installed is not right, we come back and make it right. You also pay only after the job is done.

Worth knowing

The detail, for people who like detail

Bathroom, toilet, laundry and ensuite installations

FreshDuct installs and replaces exhaust fans in every room that makes steam or smells: bathrooms and ensuites, toilets, laundries, walk-in robes off ensuites, and kitchens via ducted rangehoods. Each room gets a fan sized to its volume and a discharge path that ends outside the building – the two details that separate a working installation from a decorative one. Suburbs we cover include Fremantle, Joondalup, Subiaco, Cottesloe, Scarborough, Morley, Armadale, Rockingham, Mandurah, Canning Vale, Applecross, Claremont, Hillarys, Ellenbrook and everywhere between.

Replacements that fix the original mistake

Many Perth homes have fans that were undersized on day one or vented into the roof by the original builder. When we replace a fan we correct the whole picture – capacity, ducting and discharge – so you are not paying twice for the same shortcut.

Timers, humidity sensors and smart controls

The best fan in Perth does nothing switched off. Run-on timers keep extracting after you leave the room; humidity sensors automate the whole decision. Both are modest additions during an installation, and both pay for themselves the first winter you stop wiping down a ceiling.

New builds, renovations and compliance

Renovating a bathroom, preparing a rental for lease, or fixing items from a building inspection – we install to current ventilation requirements and document the work with photos, so your builder, agent or conveyancer has what they need on file.
