Blocked Drain Plumber in Shellharbour
Blocked drains are one of the most common plumbing problems we are called out to in Shellharbour. The signs usually start small: a shower that drains slowly, a gurgle from the toilet, a smell near the floor waste, or water rising in the yard gully after it rains. If more than one fixture is slow at once, the blockage is usually further down the line and not in a single sink or basin.
In older homes around Barrack Heights and Oak Flats, many of the original drain lines are clay or earthenware pipes, and tree roots can work their way in at the joints. In newer homes, blockages are more often caused by grease, building debris left in the line or pipes laid without enough fall. We use a drain camera to find where the blockage is and what is causing it, and then we clear the line with a high pressure water jetter. If the camera shows a broken or collapsed section of pipe, we show you the footage and explain the repair options before any digging starts.
You can read more about how we clear drains on our blocked drains page, or about camera inspections on our drain camera inspection page.
Yard Drainage and Neighbour Runoff in Shellharbour
Drainage is the work our owner enjoys most, and it is often what Shellharbour homeowners need when water keeps finding its way into the yard or under the house.
One recent Shellharbour drainage project shows how this kind of problem develops. Water from two neighbouring properties that sat higher than our client’s block was running into the yard and tracking under the slab. The homeowner was dealing with damaged new flooring, rising damp and mould inside the house. We installed a gravity fed French drain along the boundaries to catch the surface water and the water moving through the soil, and we diverted it to a concrete pit with 100mm PVC pipe running out to the kerb. We also replaced the two small downpipes with three larger Colorbond downpipes, and we built a retaining wall from concrete sleepers and galvanised steel posts to hold back the neighbouring yard. You can read the full Shellharbour French drain case study.
If water from next door is running onto your property, our article on who is responsible when water runs into a neighbour’s property in NSW is a good place to start. For more about how a French drain works, see our French drains page.

Gas Fitter in Shellharbour
Our plumbers are licensed gasfitters, so we can run new gas lines, connect gas cooktops and gas hot water systems, find and repair gas leaks, and issue gas compliance certificates. In NSW, connecting or disconnecting a gas appliance is gasfitting work that only a licensed gasfitter can do, and the gasfitter has to test the installation and complete the compliance paperwork afterwards. We handle that paperwork after every gas installation. If you can smell gas inside the house, leave the area, do not use switches or flames, and call your gas supplier’s emergency line or a licensed gasfitter.
Hot Water Repairs and Replacement in Shellharbour
We repair, replace and install electric, gas, solar and heat pump hot water systems. On homes close to the water, we check the outdoor hot water unit, the valves and the fittings for corrosion during the visit, because salt air is hard on exposed metal. If your system has stopped working, we look at the fault first and explain whether a repair or a replacement makes more sense for a unit of that age. If you are on gas, our gas hot water page has more detail, and our hot water systems page covers every type of system.
Plumbing for Older Homes and New Builds in Shellharbour
The Shellharbour area has a wide mix of housing, and the plumbing problems we see depend on the age of the home.
In older homes around Barrack Heights and Oak Flats, we often find galvanised water pipes that have corroded on the inside. Corroded pipes can cause low water pressure and slow leaks. We do not assume the whole house needs new pipes. We check the system and recommend replacing the worst sections first, which often brings the water pressure back without a full repipe.
In newer homes around Shell Cove, we are often called to fix problems left from the build. These include drains laid without enough fall, hot water systems that are too small for the household, and taps or fixtures that the owners wanted added after they moved in.
Burst Pipes, Leaks and General Plumbing in Shellharbour
We also handle the everyday plumbing in Shellharbour homes, including burst pipes, leaking taps, running toilets, split flexi hoses and bathroom plumbing. If a pipe has burst, turn the water off at the meter first and then call us on 0416 101 022. Our burst pipe repair page explains what to do while you wait.
