Exhaust fans, ventilation and leaks in a Werribee rental

The ventilation and bathroom standards, and the items that most often fail them.

Werribee 3030 · 24 September 2026

In short: A bathroom fan that blows into the roof space moves the moisture problem rather than solving it.

The ventilation standard

Bathrooms, toilets and laundries need an exhaust fan or a window that opens for ventilation.

Where fans go wrong

A fan that discharges into the roof space instead of outside air can lead to condensation and mould above the ceiling.

Leaks and slow wastes

Leaking mixers, water escaping the shower and slow wastes all affect the bathroom and mould and damp standards.

Fixing before listing

These are usually simple trade repairs, and much cheaper before a renter moves in.

FAQ

Questions Werribee owners ask about this

Can you see where the fan duct goes?

Yes, wherever the roof space can be entered safely.

Is a window enough?

An openable window can satisfy ventilation where the standard allows.

Will a slow shower fail the standard?

If it prevents the bathroom working properly, it should be fixed.

Do you test the fan?

We switch it on to see it runs; we do not certify electrical work.
