Bathrooms, laundries and kitchens are particularly prone to moisture problems caused by high humidity. The condensation and moisture created from steam penetrates crevices and feeds mold, mildew and even in some cases can contribute to structural rot of a building.

1) Do you get a build up of mould in wet areas?


2) Is your bathroom always staying damp?


3) Do you get that damp smell or toilet odours?


4) Had enough of not being able to see because of all the steam on your bathroom?


5) Do you need to open the window to have a shower?


If you answered yes to any of these questions…
The Solution is simple: get an exhaust fan into your wet areas!
But what is the best type for your bathroom?

Exhaust Fan Installation

Mould is something you never want to see in your home as it causes serious respiratory issues. A well placed exhaust fan in wet areas will lower humidity and help rid your house of mould.

Types of Exhaust Fans

There are 4 main types of exhaust fans


1) Ducted – window or wall. Using either a foil or PVC type ducting, your ducting will be installed from the fan to the outside, expelling all the moisture and fumes to outside (recommended).


2) Non ducted – Some exhaust fans simply exhaust straight into the roof cavity. Depending on what is being exhausted, you want to ensure you have reasonable ceiling space to expel to, otherwise moisture and fumes will just build up in the cavity and could create future rot problems.


3) In line – Inline is another form of ducting, where the fan is located in between the grill in your bathroom and the grill on the exterior wall. It uses foil or pvc type ducting to link them together. This is a great option where ceiling height can be an issue or you want to get a fan right above a shower. The motor is not located right above the wet point, so it doesn’t become an electrical hazard

4) 3 in 1 combo exhaust / fan / heat – Did you know that you can also get combination fittings which include lights, heating and fans? These are particularly great in cold bathrooms!

• Choice of 2 otr 4 heat lamps
• Ducted and non-ducted
• Optional remote control for homes with restricted access

Factors to be bear in mind for bathroom combination fittings

• Dependent on the model, they do require at least 250 -300mm of ceiling space
• Ducted or non- ducted? ( difference between ventilating to the outside or straight into the roof cavity)

We can supply exhaust fans for you, or you can purchase them yourself and we’ll

install them.

There is a simple formula that we apply for wet areas to work out the most suitable type of fan:

– You want to work out the volume of air in that wet area (whether it’s a bathroom or laundry) and you want to choose a fan that’s going to completely change all the air in that bathroom 12-15 times an hour.
