Need a plumber Wahroonga homes can actually rely on? Wahroonga sits at the top of the Upper North Shore – grand heritage homes on big, leafy blocks running from the village up to Ku-ring-gai Chase National Park – and that means original clay drains, ageing pipes, mature tree roots and roofs that cop the suburb’s high rainfall.
We are the local plumber for all of it: blocked drains, hot water systems, gas fitting, roof plumbing, pipe relining, leak detection and 24/7 emergency plumbing, for homes and businesses across the suburb, with upfront pricing, no hidden costs and a $0 call-out fee.

Our Wahroonga plumbers handle every kind of plumbing work - emergency repairs, routine maintenance, new installations and upgrades - across residential and commercial properties alike.
Between the mature trees and the decades-old clay drains under most Wahroonga homes, blocked drains are the call we get most. Tree root intrusion, leaf litter, grease and debris slowly choke older pipes until the water backs up. We send CCTV drain cameras down the line to locate the exact blockage, clear it with high-pressure water jets, and show you what caused it - so you’re not back in the same spot next month.
When a drain has cracked, or roots have forced their way in, pipe relining repairs the pipe from the inside - no trench across a heritage garden or established lawn, and minimal disruption to the property. The cured liner seals every joint, restores full flow and tends to outlast the pipe it lines, which makes it the ideal long-lasting solution for older Wahroonga properties.
Large Wahroonga households run their hot water hard, so a system that leaks, runs cold or trips out gets our quick attention. We handle hot water repairs, servicing, installation and replacement across gas, electric, solar and heat-pump hot water systems from all major brands - and we’ll give you a straight repair-or-replace answer, not the most expensive one.
Wahroonga’s big trees and high rainfall are hard on roofs. Leaf litter and moss build up in gutters and valleys, and after a heavy downpour, water finds its way in through slipped tiles, rusted fixings or overflowing gutters. Our licensed roof plumbers clear and repair gutters and downpipes, sort roof leaks at the source and keep stormwater moving off the roof and away from the house - before the rain causes costly damage inside.
From leaking taps, dripping taps and running toilets to burst pipes and the hidden leaks that quietly lift your water bill, we solve the everyday plumbing issues and the hard-to-find ones. Advanced detection technology - acoustic and thermal equipment - pins the leak down precisely, so the repair is targeted rather than a guess that wrecks the plaster.
A plumbing emergency at this end of the line needs someone who will actually turn out. Burst pipes, overflowing toilets, gas leaks, no hot water - whatever the urgent issue, our emergency plumber is available 24 7, day or night, weekends and public holidays included, with the cost agreed before we start and no fee just to attend.
Plenty of Wahroonga homes run gas cooktops, heaters and hot water, and a good number of them were connected decades ago. Our licensed gas fitters install and replace appliances, run and repair gas lines, trace leaks when you can smell gas, and leave a compliance certificate behind on every job. If the smell is strong, turn the appliance off at the isolation valve, open the windows and call us straight away rather than waiting.
Wahroonga is big, and it is not one thing. The plumbing we find changes depending on which end of it you are standing in, so it helps to say where we actually work.
Around Redleaf Avenue, Coonanbarra Road and the shops, the mix is period houses on generous blocks alongside unit blocks and townhouses close to the station. The houses are on original clay and earthenware drain lines; the unit blocks bring shared drainage, shared hot water and the question of whose pipe it is when something backs up.
North Wahroonga is its own suburb, up past the freeway edge with Ku-ring-gai Chase National Park at its back, and we cover it exactly the same way we cover Wahroonga proper. Bush blocks, long private drain runs and heavy leaf load are the pattern here, which means tree roots, stormwater pits that silt up and drains that need a camera before anyone quotes a repair.
The Fox Valley Road and Comenarra Parkway end has the Sydney Adventist Hospital, the medical suites and offices around it, and homes on the slopes below. Work here is split between household plumbing and commercial jobs where access and timing have to be arranged rather than assumed.
Wahroonga runs into Warrawee to the south and Turramurra to the west, and the housing does not change at the boundary line. If you are on one of those streets and are not certain which suburb you are in, it makes no difference to us.
We also work across Waitara, Normanhurst, Thornleigh, Hornsby and North Turramurra on the same day runs.
Wahroonga is the northern gateway to the Upper North Shore, on the rail line about 18 km from Sydney’s CBD, and one of the few suburbs spanning two councils: Ku-ring-gai for most of it and Hornsby Shire to the north. It’s known for the village, Wahroonga Park, Knox Grammar, 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 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 enormous, the roots are everywhere, and the bush-fringed blocks plus the suburb’s high rainfall make stormwater and gutters a genuine, recurring job. Our experienced Sydney plumbers work across the whole suburb and the surrounding suburbs with CCTV drain cameras, water jetting equipment, leak-detection gear and gas-testing tools on every van - so we can read the problem properly on the first visit and quote it before we start.

Heritage homes & bush blocks
A few issues come up again and again on Wahroonga’s big residential blocks. Here is what tends to be behind them, and the way we actually put each one right.
Wahroonga’s tree-lined streets and bush-backed blocks send roots straight into the joints of old clay drains. Tree root intrusion starts small - a slow drain, a gurgle, an odd smell - then the roots catch debris and grow until the line backs up completely, almost always worse after heavy rain.
We camera the drain to map every entry point, clear it with high-pressure water jetting, 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 pipework. After many decades, older pipes corrode, narrow and leak - turning up as low water pressure, rusty water, mineral buildup around fittings, or damp that seems to come from nowhere.
We pinpoint the failing run with a camera or leak detection, then reline or renew just that section with new pipework and leave the sound pipe in place.
Blocks near Ku-ring-gai Chase collect a heavy load of leaves and silt, and the ground often falls toward the reserve. When gutters, pits and stormwater drains clog, a storm pushes water across the yard, into the eaves or back at the house instead of away from it - and the water damage adds up fast.
We clear gutters and stormwater lines, camera the underground runs, check the falls, and repair or re-lay pipe so run-off is carried safely off the block.
A big Wahroonga home with several bathrooms can outpace an ageing hot water system. It shows up as cold showers when two things run at once, fading pressure, or a unit that quits on the coldest morning of the year.
We test the system, repair it where that genuinely makes sense, and when it’s done, we size a new installation to the household - often running again within hours.
The big, established gardens here feed a steady stream of leaf litter, grease and silt into outdoor drains and gully traps. They clog slowly, 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 you honestly whether a clean-out will hold or the pipe needs repair.
In an older Wahroonga home, a small leak can run for months inside a wall or beneath the floor - lifting the water bill, softening timber and staining plaster while giving away little more than a musty smell or water stains.
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.
Three jobs that come up often enough here to be worth describing, so you can see how we work through them rather than reading another list of services.
A Federation house on a big block, and every year when the leaves drop the laundry gully starts backing up. The owner has had it cleared three times. We camera the line and find roots through a joint about twelve metres out, under the lawn. The clear gets it flowing again; the reline seals the joint so the roots have nothing to grow into. The cost of relining that one section is usually less than the next four call-outs.
A 1920s home where a damp patch appears in the hallway ceiling and nobody can say where the water is coming from. We use acoustic and thermal gear to narrow it to a joint in the wall cavity rather than opening the plaster across the ceiling. One small access hole, one repair, and the plasterer has a patch instead of a project.
A bush-backed block where a heavy storm pushes water over the gutters and into the eaves. The gutters are full of leaf litter, the downpipe has silted up and the stormwater pit below it has not been cleared in years. We clear the lot, camera the underground run, check the falls, and repair the section that had collapsed. The gutter guard conversation comes after that, not instead of it.
Not every property here needs the same approach. These are the four we are called to most, and what changes about the job in each one.
A large part of Wahroonga went up between the 1890s and the 1930s, and some of it sits inside heritage conservation areas under the Ku-ring-gai and Hornsby planning controls. That shapes the work: no trench across a listed garden where relining will do the job, careful work around original fittings, and repairs that keep the look of the house rather than fighting it.
The blocks near the station and along the highway bring shared lines, shared hot water plant and leaks that travel between floors. We camera the drain first so there is no argument about whether the fault sits on common property or inside one lot, and we give the strata manager the footage with the quote.
Wahroonga has an unusual concentration of schools and medical buildings for a residential suburb, and they have their own rules: work in term breaks or after hours, keep the site clean and safe, and get it signed off properly.
For managed properties we attend, diagnose, send the quote through and keep the tenant informed about the time. If the job needs an owner decision, the photos and the camera footage go with the quote so the agent is not relaying a description.
Finding a reliable plumber shouldn’t be a gamble. Our licensed plumbers turn up when we say we will, treat your home with care, and deliver quality workmanship with clear communication from start to finish - it’s why Wahroonga locals, landlords and local businesses keep calling us back, and why our customers recommend us to their neighbours.

It comes down to the job - the access, the age of the pipes and the repair needed - so we quote after a proper look rather than guessing over the phone. There’s no call-out fee; the quote itself is free, and the pricing is fixed and upfront before work begins, so the figure you approve is exactly what you pay. No hidden costs, ever.
No. There’s nothing to pay for us to come out to your Wahroonga property and assess the problem; the only cost is the work you’ve agreed to at a fixed, upfront quote.
Yes - our emergency plumber is available 24 7, day or night, weekends and public holidays included, for burst pipes, blocked drains, overflowing toilets, gas concerns and hot water failures, with the cost confirmed before we begin.
Low water pressure is one of the most common plumbing issues in older Wahroonga homes. The usual causes are ageing galvanised pipes that have narrowed with corrosion and mineral buildup, a hidden leak somewhere in the line, or a failing pressure valve - and the suburb’s hilly terrain doesn’t help. We test the system, find the cause and give you honest options, from a targeted repair to new pipework where the old run is genuinely finished.
Yes. Roof plumbing is a big part of the work here - Wahroonga’s heavy tree cover and high rainfall mean gutters clog and roofs leak more than in most of Sydney. Our licensed roof plumbers repair leaks, clear and repair gutters and downpipes, and sort the stormwater drainage that carries it all away.
Yes. We cover Wahroonga from the village and the station precinct through to Fox Valley, on both the Ku-ring-gai and Hornsby Shire sides, and North Wahroonga next door, which is its own suburb running up to Ku-ring-gai Chase National Park. Same day service, same $0 call-out fee, whichever end you are at.
Yes. R&G Plumbing is fully licensed and insured for plumbing, drainage and gas; every job is done by a licensed tradesperson, and all our plumbing work is backed by a workmanship guarantee.
Yes. Our gas fitters are licensed for installation and repairs: cooktops, ovens, heaters, gas hot water and bayonet points, plus leak tracing and line repairs. Every gas job finishes with a compliance certificate. If you can smell gas, turn the appliance off, open the windows and call rather than wait for the morning.
We are based at Gordon, a short run up the Pacific Highway, so Wahroonga and North Wahroonga jobs usually get a same-day slot and urgent ones are often within the hour.
That is exactly what relining is for. We reline the pipe from the inside through an existing access point, so established gardens, driveways and lawns stay as they are. On older Wahroonga properties it is usually both the cheaper option and the one that avoids an argument about reinstating a garden that took forty years to grow.
Because clearing a blockage and fixing its cause are two different jobs. If roots are coming through a cracked joint, a clear buys you a season and the roots come back to the same opening. The camera shows whether you are dealing with a one-off build-up or a structural fault, and we tell you which one it is before quoting anything.
Yes, and they are some of the most common calls we take up that end. Bush blocks bring heavy leaf load, long drain runs and stormwater that has to be managed properly, so gutters, pits and underground lines need checking before storm season rather than after the water has already come in.
