Recent Work Near Thornleigh
Real jobs from our own records, completed in the surrounding suburbs.
The 2021 Census counts 3,159 private dwellings in Thornleigh, 77% of them separate houses, so most of our work here is on a home's own sewer line, water service and hot water system rather than a shared block. Sydney Water looks after about 27,000 kilometres of wastewater pipes and clears up to 20,000 blockages a year, but the line from your house to the street connection is yours to maintain, and that is the stretch where tree roots, old clay joints and ground movement do their damage. If you would rather not find out the hard way, our VIP members get a free annual home inspection that checks the drains, taps and hot water before anything fails.
A Wahroonga customer reported a broken roof tile and a hole in the roof in March 2026. Our plumber sourced materials, including fast flash, a downpipe adaptor, PVC pipes, clear glue, and primer. The flashing was tested, and the downpipe was tested to ensure correct water flow. Our plumber washed down debris from the roof.
Our plumber attended a South Turramurra property in March 2026 where the customer wanted to replace a flue for the hot water system. We supplied and installed a new 135L gas internal hot water system, along with a new PLV, duo valve, and PRV. We tested the works. We then installed the flue with new flashing.

In June, our plumber attended a blocked shower drain in Asquith. The customer reported hair buildup. We provided a quote for the work, which was accepted.
In August 2026, our plumber attended a blocked sewer drain in North Wahroonga. We excavated a broken section of terracotta under a tree. We then re-CCTV'd and jetted the line. We supplied and installed approximately 8 metres of pipe with fittings to the shaft riser at the rear of the property. We completed the work.

Thornleigh Plumbing FAQ
Answer:
That depends on which side of the meter it is. A leak between Sydney Water's pipes and the meter, up to one metre inside the property boundary, is repaired by Sydney Water for free; the pipes after the meter belong to the owner (Sydney Water). 76.6% of Thornleigh homes are separate houses (ABS 2021 Census). For a leaking tap or a hidden leak on your side, we repair it at a fixed price.
Answer:
Yes. A high-pressure jetter is our first step on an active blockage. Afterwards a camera inspection, free with any booked drain service, shows what caused it. If the pipe is cracked, pipe relining can repair the damaged section without digging it all up. 31.5% of Thornleigh homes are owned outright (ABS 2021 Census); every owner gets the price before we start.
Answer:
Yes. We do bathroom renovations as well as everyday plumbing, so the same licensed team (NSW licence 306457C) handles the pipes, fixtures and fit-off. 15.6% of Thornleigh homes are semis, terraces or townhouses (ABS 2021 Census); in a strata scheme, check what the owners corporation controls before work starts (NSW Government). You get a fixed price up front and 0% interest payment plans.
