Licensed Master Plumber - CIPP Lining

Read This Part First

Let's be upfront about what this job is, because it isn't a normal master plumber seat.

---

This is a lining job.

Roughly 80% of your week is CIPP — full liners, point repairs, jetting, camera work.
The other 20% is the light plumbing that comes up on those lining projects.
We do not do repipes. We do not do plumbing-only jobs. We are not going to turn you into a service plumber running calls.

What your license does is let us stop subbing out the plumbing side of our own lining work, and let us pull our own permits. That's it. That's the whole ask.

---

What does that plumbing work consist of? Usually minor things... cutting out a 3' portion of the sewer line underneath the basement floor so we can get our lining equipment in there... cutting out a vertical stack and replacing it with PVC... installing new floor cleanouts after we break them... pulling and resetting toilets...

So if you're a master who's tired of repipes and water heaters and would rather run trenchless work all day — this is a very good seat.
If you want to be a full-time plumber, you'll hate it here, and we'd rather you know that now.

What We Do

Cleaning: Milwaukee and Picote equipment, van- and trailer-mounted hydro jetters
Full lining: CIPP by inversion and pull-in-place, hot water cure and UV cure
Spot lining and point repairs: ambient cure and UV cure, 2-foot sections up to 20-foot runs

We're expanding into five new markets over the next five years.
The person who takes this role gets in before that happens.

*** THE GOAL WITH THIS POSITION -- You would go from 100% in the field, to being a field supervisor, to being a plumbing manager. ***
