About Us

Tradesmanship you can Trust

At Cozy NZ, we realise that your home is one of your biggest investments. Looking after that investment as well as improving it, is what we’re all about.

We pride ourselves on our quality trademanship and continued improvement. That’s why we are members of the Master Builders Association as well as the Windows & Glass Association of New Zealand and our installers are fully certified tradesmen.

Not only that, we partner with the best. All of our double glazed units are manufactured using Viridian Glass, ensuring high quality, high performance glass.

Our point of difference is our people, quality service, qualified staff and years of industry experience. Would you want anything less? 

The Important Stuff – a few things that are present in everything we do:



Ensuring that you make the best, most informed choice and understand our process is of top priority to us. We sleep better knowing that you made the best possible decision for your home.



We spend a lot of time in and around our client’s homes and we understand that involves a lot of trust on your part. It has always been our top priority to treat your place with as much care as we treat our own.



We are proud to call ourselves specialists in our industry. This means we complete every one of our projects to the highest of standards and don’t finish until we are satisfied that every element works as it should.
