The plumbing
under the house
you’re building.
New builds, renovations, additions, conversions — and the systems they sit on. Underslab pipework, drainage stacks, gas runs, hot water. The work that goes in before the linings, designed to last the life of the house.
The work that disappears into the wall — and has to be right.
Most of our residential work is the kind that nobody ever sees again once the linings go up. Underslab pipework. Drainage stacks for apartments. Black and grey water lines. Subsoil drainage behind block walls. The pipes that move clay-to-PVC across decades of an old boathouse bathroom.
That work is exactly the work most worth getting right. It’s also the work where we earn the architects and the builders we partner with — by reading drawings carefully, by sizing systems for the actual building, by being where we said we’d be.
From Pokeno in the south to Silverdale in the north, on garage conversions, granny flats, full new builds and full restorations.
