Local North Shore plumbing

Plumbing services

No plumbing issue too big, or too small. From a dripping tap to a new sewer line or a full bathroom, done by our own licenced team.

What we actually do, and who does it

STS Plumbing has been on the North Shore since 2007, based in Mosman, then Crows Nest, and in Lane Cove since 2016. There are four plumbers, a recently qualified plumber, an apprentice, the office and Simon. Everyone who turns up at your place works for STS.

Between the licences we hold, most of what a house or a building needs can sit with one company: plumbing, gas fitting, drainage, roofing, waterproofing, and kitchen, bathroom and laundry renovations. That matters most on the jobs where the trades meet, because that is where things get blamed on someone else.
