STS Plumbing is the local plumber you can depend on

On the North Shore since 2007, and based in three of the suburbs we work in along the way: Mosman, Crows Nest and Lane Cove.

Local experts

Local means we can get to you fast. Old sewer lines, sandstone, big trees and harbour weather are everyday work for us.

Upfront pricing

You get the price before the work starts, agreed with you, and reduced rates for our North Shore neighbours.

Our own team

Licenced plumbers who work for STS, not subcontracted labour, in signwritten vehicles with our name on them.

What we do

No plumbing issue too big, or too small

We find the blockage, clear it, then show you the camera footage so you can see what caused it. Every choke priced on the spot.
