Plumbers across Australia are making the switch
"Neolag sleeves are so much easier to install than the old products we used. Once they're in, we can walk away knowing steel fixers and other trades won't damage them. Game changer for our business."
Taylor
Silk Plumbing and Gas
"Chalk and cheese compared to what's on the market. These sleeves stay put no matter what happens on site. We don't worry about callbacks anymore – they just work."
Josh
Time Wise Plumbing
"Finally, a sleeve system that can handle the rough treatment from other trades. Installation is quick and we know it won't fall off or get damaged. Much better than anything else available."
Nick
Coastline Plumbing Group
"Neolag turned a two-man job into a one-man install — and it stays secure."
Josh
J Group Plumbing
"Been on the tools 15 years and this is the first sleeve that actually bloody works. No muckin' around with tape or wrap — just slide it on and done. Should've been around years ago."
Mick
Mick's Plumbing
"We used it on a big pour last month. Normally we're faffing around with poly and tape that rips and tears when the other trades come through. Good to see an Aussie plumber come up with something that saves us time."

Founder & CEO
After more than 25 years in the plumbing industry, our founder and CEO, Josh Leitner, had seen the same problem play out time and time again — the struggle to properly isolate drainage pipes passing through concrete. Traditional wrapping and taping methods were slow, awkward, and unreliable. That frustration sparked the idea for Neolag.
