"My house was damp and condensation on the windows left a pool of water on the windowsills. Had Better Vent installed 2 weeks ago and WOW — what an amazing difference. No more dampness, the house feels so much drier, and no more crying windows. An absolute pleasure from start to finish."
"The results were basically instant. Our bedroom windows would always be wet in the morning — but the next day after installation, the windows were dry! Affordable, professional, reliable and tidy. Highly recommend."
"The windows were very wet on cold mornings — now after a couple of weeks they are completely dry and the house feels much warmer. The online quote and installation was a completely painless process. Would definitely recommend to anyone."
"Excellent communication and service. You can't hear a thing and the vents have been fitted well. We saw the difference immediately — no more condensation! I would recommend these guys to everyone."
"We can feel the difference in dryness. The airflow is consistent and makes a definite difference in our home. The installation was simple and the cost represents real value for money."
"Easy and quick quote and booking. Professional installation, and a much more affordable option thanks to a simple but effective system."
The big ventilation brands charge more — not because their systems are better, but because of how they run their businesses. We've installed ventilation systems across Porirua and the wider Wellington region, and we understand what the harbour city's cold, damp winters do to homes. Many Porirua homes — particularly those in valleys and sheltered areas — trap moisture inside, leading to condensation and mould. By cutting out the sales teams, TV ads, and in-home consultations, we pass those savings directly on to you.
No door-to-door reps, no pushy in-home consultations, no referral fees. You get a fixed price online in minutes — no sales visit required.
While the big brands sponsor sports teams and run TV campaigns, we grow through word of mouth and honest reviews — and pass that saving on to you.
Most customers with control panels rarely touch them. Our system automatically adjusts between summer and winter modes — there's nothing to programme or manually switch. It's one genuine area we save on cost, with no impact on how well the system works.
We use reliable, high-grade components chosen for the New Zealand climate. Every installation is backed by a 6-year warranty, and we've installed over 1,000 systems across the country.
Porirua's cold winters and harbour-side location create the conditions for moisture to build up inside homes. Many properties in the area — especially those in lower-lying streets and older housing stock — struggle with condensation on windows, damp wardrobes, and mould in bathrooms during the cooler months.
Better Vent's system draws dry, filtered air from your roof cavity and pushes it through your home, replacing the cold, stale air that allows moisture to settle. Our hospital-grade F8 filter removes dust and allergens, and the whole system runs quietly and automatically during winter — with no input needed from you.
It's one of the most cost-effective ways to tackle condensation and mould in a Porirua home, at a price that reflects what it actually costs to make and install.

You can buy new filters from us, online or from Bunnings for $55 plus shipping.
Yes! Replacing filters is easy to do yourself and won't affect your warranty with us.
We recommend replacing filters every 2 years.
The same reasons we're more affordable everywhere — no door-to-door sales teams, no TV advertising, and no expensive in-home consultations. We quote online and keep our overheads low, passing those savings directly on to Porirua homeowners. You get the same quality system as the big brands, at a significantly lower price.
We don't offer a wall control panel option. Our system runs fully automatically and therefore doesn't need one. Most customers find they never use them anyway. We can install a wall switch to give you manual on/off control.
Yes we can! Get in touch and we can give you a price.
We don't recommend them. Unfortunately even with a Summer add-on taking air from outside, the air entering your home will be warm as all the ducting is in the hot roof space.
On average, for a typical 4 outlet system, our system draws less than 10 watts of power. Assuming you pay $0.30/kwh, it costs less than $3 a month to run!
All positive pressure ventilation systems work in a similar way. Our system takes dry air from your roof space and uses it to displace the damp air in your home. During the day, the fan unit runs at full speed to make the most of the warm roof space air. At night the air is cooler, so the fan runs at a low speed — just enough to avoid condensation forming. There's no cold draughts — most people never notice it's running.
Our automatic smart sensor takes care of everything! And in Summer it turns the fan off so you don't have hot air blowing into the house.
