Wahroonga sits at the top of the Upper North Shore, an established, heavily treed suburb of grand heritage homes that runs from the village and the station up to the bushland edge of Ku-ring-gai Chase National Park. The houses here are among the oldest on the North Shore, which means original drainage, mature tree roots and pipework that has seen a few decades, the kind of work we deal with every week. R&G Plumbing covers blocked drains, hot water, gas, pipe relining, leak detection and 24/7 emergencies across the suburb, with a fixed price agreed up front and no call-out fee.

Wahroonga is mostly large, long-held family homes, with the village shops and the odd small business in the mix, so the plumbing tends to be older and more involved than most. We take on the urgent and the everyday alike, and we settle the cause and the price before any work starts.
Between the mature trees and the decades-old clay drains under most Wahroonga homes, blocked drains are the call we get most. We send a camera down to find the exact blockage, clear it with high-pressure jetting, and show you what caused it so you are not back in the same spot next month.
When a drain has cracked or roots have forced their way in, relining repairs it from the inside, with no trench across a heritage garden or an established lawn. The cured liner seals the joints and restores full flow, and it tends to outlast the pipe it lines.
Large Wahroonga households run their hot water hard, so a unit that leaks, runs cold, or trips out gets our quick attention. We service and replace gas, electric, solar and heat-pump systems, and we will give you a straight repair-or-replace answer rather than the most expensive one.
Our licensed gas fitters install and service cooktops, ovens, heaters and gas hot water, lay new gas lines and issue compliance certificates. A gas smell is not something to sit on: call us, get everyone out into fresh air, and we will test, isolate and make it safe.
From the small jobs, dripping taps, running toilets and tired mixers, to the leaks hidden in a wall or under a floor, we cover both. Acoustic and thermal detection pins the leak down so the repair is targeted, not a guess that wrecks the plaster.
Up at this end of the line, a burst pipe or sewer overflow needs someone who will actually turn out. We answer Wahroonga emergencies around the clock, every day of the year, often same-day, with the cost agreed before we start and no fee just to attend.
Wahroonga is the northern gateway to the Upper North Shore, on the rail line about 18 km from the city, and it is one of the few suburbs that spans two councils: Ku-ring-gai for most of it and Hornsby Shire to the north. It is known for its village, the Sydney Adventist Hospital at Fox Valley, and grand heritage homes on big, leafy blocks that run right up to the edge of Ku-ring-gai Chase National Park.
All of that history shows up in the plumbing. Many homes are among the oldest on the North Shore, still on original clay drains and ageing galvanised or copper pipes. The trees are large, and the roots are everywhere, and the bush-fringed blocks make stormwater a real job in heavy rain. We work across the whole suburb with CCTV cameras, jet blasters, leak-detection gear and gas-testing equipment on every van, so we read the problem properly the first time and price it before we start.

Heritage homes & bush blocks
Because Wahroonga’s homes are old and its blocks are big and tree-heavy, a handful of issues recur right across the suburb. These are the ones we attend most, with the real cause and the repair that actually holds.ry.
Wahroonga’s tree-lined streets and bush-backed blocks send roots straight into the joints of old clay drains. They take hold, catch debris and grow until the line slows, smells or backs up, almost always worse after a good downpour.
We camera the drain to map every entry point, clear it under high pressure, and reline the cracked section so the roots are sealed out for good.
Some of Wahroonga’s houses are among the oldest on the North Shore, and plenty still carry their original galvanised and copper pipe. After this many decades, it corrodes, narrows and leaks, turning up as poor pressure, rusty water or damp that seems to come from nowhere.
We pinpoint the failing run with a camera or leak detection, then replace or reline just that section and leave the sound pipe in place.
Blocks on the bushland edge collect a heavy load of leaves and silt, and the ground often falls toward the reserve. When pits and stormwater lines clog, a storm pushes water across the yard or back at the house instead of away from it.
We clear and camera the stormwater lines, check the falls, and repair or re-lay pipe so the run-off is carried safely off the block.
A big Wahroonga home with several bathrooms can outpace an ageing hot water system, which shows up as cold showers, fading pressure or a unit that quits when you least want it to.
We test it, repair it where that makes sense, and when it is genuinely done, we size a replacement to the home and usually have it running the same day.
The big, established gardens here feed a steady stream of leaf litter and silt into outdoor drains and gully traps, which clog slowly and then overflow, often a fair way down the line from where the trouble shows.
We clear the blockage at its source, then camera the run to tell whether a clean-out will hold or the pipe needs repair.
In an older Wahroonga home, a slow leak can run for months inside a wall or beneath the floor, lifting the water bill and softening timber while giving away little more than a stain or a musty smell.
We trace it with acoustic and thermal leak detection, then open up only the spot at fault so the repair is quick, and the mess is minimal.
