Winter showed you exactly where your home is losing heat.
Insulate your walls in just 1–2 days — with no major renovations or mess — and enjoy a warmer, more comfortable home through the remaining cold nights and beyond.
Up to 40% of the heat you pay for walks straight out through your walls. Your heat pump is working overtime — and you're footing the bill every month.
Heating an uninsulated home in Christchurch winter is like leaving a window open. Your walls are the single biggest upgrade you can make to reduce running costs.
Cold, damp homes are linked to respiratory illness, poor sleep, and worse wellbeing — especially for young children and the elderly. Insulation isn't just comfort, it's health.
Don’t wait until your home is freezing again. Arrange your free assessment this spring, get ahead of next winter’s rush, and make sure the cold season you’ve just experienced is the last one your home feels like this.
We assess your home and provide an accurate, no-obligation quote. Takes about 20 minutes.
Small holes are drilled in your exterior wall. CosyWall insulation is blown in at high density to fill every cavity.
Holes are plugged and colour-matched. No sign we were ever there — except a warmer home.
Most homes are complete in a single day. You can stay home. By evening, you'll already feel the difference.
The difference in our 1960s home has been immediate — warmer, more comfortable, and even quieter. It’s made a bigger impact than we expected and is easily one of the best upgrades we’ve done.
The installation was tidy and efficient, and everything was explained clearly along the way. You can tell these guys really know and love their stuff.
Canterbury insulation were 35% cheaper than the competition, and we couldn't be happier with the job they've done. Great team, the outside of the house looks exactly the same as it did before and we can feel the difference inside immediately. Thanks so much.
After many years living in a cold house, we recently got our whole house insulated with Matt and his team. Can't speak high enough made whole process quick and easy. Our home is now warm and cozy. We can't believe the difference noticed already. Thank you all so much! They did such a tidy job and we're so professional and lovely to deal with.
