Always check specifications for this product and watch our 5 Part step-by step installation videos.
Now the second time I've used this product, very easy to handle and install. Every room I've done makes a massive difference.
I am by no means a DIY specialist. Having got rid of our gas heater I wanted to seal our ducts quickly and easily (oh, and cheaply of course). So after hours of searching, I found ecomaster. Anyway, I carefully watched the videos and decided to give them a go. I'm glad I did. They were surprisingly easy to install. All my vents were random sizes just a little smaller than standard, so I had to cut the boards. But that was easy. Then, shove them in and seal them up. It really was that easy, and I was surprised to have 9 vents done in an hour. The heater intake took a little longer as I had to crawl inside the linen cupboard to seal it, but I got there.
I would highly recommend these kits, and it's always nice to support a small local Australian company. I had a lovely chat with Lyn when I picked up the kits at their Preston warehouse too, which really helps provide that human touch.
This is the second lot I’ve purchased . It did such an amazing job of sealing up the drafts and gaps in my floorboards.
So easy to use that I am continuing into the remaining rooms.
