From our reviews
Under the floor
The musty smell. The mould back in the wardrobe. Floors that feel damp. Most of it starts down here.
- A musty smell that comes back soon after you air the house.
- Mould on clothes and shoes in wardrobes, or behind the bedhead.
- Floors that feel cool and damp underfoot.
- A building or pest inspector has said the sub-floor needs more ventilation.
“I've already got brick vents.”
So why is it still damp under there? Try it.

About us
Who you'll deal with
Brián Patten, Director
We started as electricians, and we added ventilation because we kept finding the same damp problems under the houses we were wiring.
Brián runs Inspire and Brendan works alongside him. Whoever comes to look at your job is who comes to do it. There's no sales rep.
We're based in Davidson on the Northern Beaches, and we also work across the North Shore, the Eastern Suburbs and the Inner West.

Frequently asked questions
How much does subfloor ventilation cost on the Northern Beaches?
Our systems are $2,400 to $4,600 including GST, with a 7-year warranty. The size of the sub-floor and the number of fans decide where yours lands. We look first, then send a fixed price in writing.
I've already got brick vents. Why is it still damp under there?
Brick vents only work when wind happens to push air through them, and many are now partly blocked by decks, paving or garden beds. A fan system moves the air every day, whatever the weather.
Will it get rid of the musty smell?
If the smell is coming from damp under the floor, moving that air out is what fixes it. We'll tell you at the look if we think the cause is something else.
Do you do the electrical for the fans too?
Yes. We're licensed electricians, so the power, the controller and the fans are all one job and one quote.
Is the price really fixed?
Yes. Once you've accepted the written quote, that's the price. If we find a genuine surprise, we stop and show you before doing anything extra.
How long does an install take?
Less than a day. Most installs take four to six hours, with two of us on site.
Is it noisy?
Not much. We hang the fans on suspension mounts to cut vibration, and they run at a low hum, under 41 decibels.
Are you licensed for this work in NSW?
Yes. NSW Electrical Contractors Licence 503808C. It's on every quote and at the foot of every page.
Who actually turns up?
One of the two of us. If your job needs a specialist, like a Level 2 service provider for the meter, we tell you first and organise them.
How soon can you come and look?
Usually within five days.
The price we quote is the price you pay.
- 1
We come and look. Under the house, in the roof, at the board. We take photos as we go.
- 2
You get the quote in writing, with the photos, so you can see what we saw.
- 3
Once you say yes, the price doesn't move. If we open something up and find a real surprise, we stop, show you, and quote it before we go any further.
We'll call you back, usually the same working day.
