Pennant Hills sits high in the leafy north-west of the Upper North Shore, in the Hornsby Shire, part established family suburb and part town centre, where the village shops and station meet a major road junction and the bush. National parks wrap around it, Lane Cove to the east and Berowra Valley to the north-west.
The land is hilly, and the blocks are generous, and most homes have been here long enough to have some age in their pipes. R&G Plumbing looks after all of it, blocked drains, hot water, gas, pipe relining, leak detection and emergencies any hour, with a fixed price agreed first and no call-out fee.

Pennant Hills runs from big family homes on bush-backed blocks to townhouses and units around the village centre, so the plumbing covers a fair range. From a quick repair to a full drain reline, we take it all on, and we always nail down the cause and the price before we begin.
Ringed by national park and creek gullies, Pennant Hills sends a lot of tree roots into its older drains, which is the usual reason a line here blocks. We camera the drain to find the exact spot, clear it with high-pressure jetting, and show you on screen what was behind it.
On a hilly, bush-backed block, digging up a drain can mean tearing through a sloping garden or a long driveway, so relining is often the smarter fix. We rebuild the pipe from the inside, seal out the roots, and leave the lined drain stronger than it was.
The large family homes here run their hot water hard, so a unit that leaks, runs cold, or trips out gets prompt attention. We repair and replace gas, electric, solar, heat-pump and continuous-flow systems, and size any new one to suit the household.
Because gas is licensed work, our gas fitters take care of cooktops, ovens, heaters and gas hot water, install new gas lines and issue the compliance certificates. If gas is ever in the air, take it seriously: call us, let the place air out, and we will test, isolate and make it safe first.
A leak on a big Pennant Hills block can run a long time before it surfaces, so along with the everyday taps, toilets, mixers and burst pipes, we track down the hidden ones. Acoustic and thermal detection puts us on the source, so the repair stays small.
A burst pipe or sewer overflow up here does not keep office hours, and it still needs someone who will turn out. We answer Pennant Hills emergency calls at any hour, on any day of the year, and are often there the same day, with the cost agreed beforehand and nothing charged just to come out.
Pennant Hills sits about 18 km north-west of the city in the Hornsby Shire, high on the ridge at postcode 2120, one of the shire’s town centres alongside Epping and Hornsby. Its village along Yarrara Road, the library and the station sit beside Pennant Hills Road and the M2, while national parks press in on most sides, Lane Cove to the east, Berowra Valley to the north-west, and Devlins Creek to the south. The terrain is hilly and sandstone, and the homes are mostly large and established on generous, leafy blocks, with townhouses closer to the centre.
The surrounding bush sends roots into old drains, the steep blocks and creek gullies make stormwater a real job, many homes still run decades-old clay and galvanised pipe, and big households put steady demand on hot water. We turn up ready for it, with CCTV cameras, jet blasters, no-dig relining gear, leak detection and gas-testing equipment on every van, so we find the real fault on the first visit and quote it before we start.

Most of the plumbing trouble in Pennant Hills comes from its bush surrounds, its steep blocks and the age of its homes. Here are the ones we see most often, the usual cause of each, and the way we deal with it.
Pennant Hills is hemmed in by the Lane Cove and Berowra Valley national parks and the Devlins Creek gully, and all that bush keeps roots hunting for water in the joints of old drains. Once in, they catch waste and grow until the line slows, smells or backs up, almost always worse after rain.
We camera the line to map every root entry, cut and flush it out under pressure, and reline the cracked section so the roots are locked out for good.
Pennant Hills is hilly, and plenty of blocks fall away toward the bush or a creek gully, so when stormwater pits and lines clog with leaf litter, a heavy downpour runs across the yard or back at the house instead of safely away.
We jet and camera the stormwater pits and lines, correct the falls where we can, and re-lay or upsize pipe so a downpour runs down the slope and away from the house rather than banking up.
Many Pennant Hills homes have stood for decades and still drain through clay and earthenware, which cracks, sags and lets roots in, while their galvanised supply pipe corrodes and narrows, showing up as slow drains, low pressure or damp with no clear cause.
We camera or leak-test to find the failing run, then repair or reline only that part and leave the sound pipework in place.
A big Pennant Hills household with several bathrooms can run an ageing hot water system past its limit, which turns up as cold showers, fading pressure or a unit that fails on the coldest morning.
We test the system and repair it where it still makes sense, and when it is past saving we fit a replacement sized to the household and can usually have it running the same day.
Around the station and the village, Pennant Hills has townhouses and unit blocks where drainage and hot water are often shared, so a problem in one home can quietly become a common-property issue.
We trace the fault across the shared services, work in with the owners or strata manager, and repair it with clear reporting and as little disruption to the other residents as possible.
On a large, sloping Pennant Hills block a slow leak has room to hide for months, soaking into the ground or under the slab while it lifts the water bill and shows little more than a damp patch.
We pinpoint it with acoustic and thermal leak detection, then open up only the spot at fault and leave the rest of the block undisturbed.
