Service details

Plumber installing a Rheem hot water system against an external brick wall

Hot water systems

No hot water is the call we get most. We replace and repair gas, electric and heat-pump systems across Mandurah and Perth metro. Rheem, Rinnai, Dux and Bosch are stocked on the van, so most replacements happen the same day you call.

Ollie is a licensed plumber and gas-fitter, so a gas changeover is handled end-to-end without subbies. We pull the old unit, fit the new one, pressure-test the lines and leave the site clean. Workmanship is covered by a 5-year guarantee.

If your unit is leaking from the base or rusting at the seams, it's done — replacement is cheaper than the next callout. Send a photo of the data plate and we'll quote before we arrive.

  • Rheem, Rinnai, Dux, Bosch
  • Same-day replacement available
  • 5-year workmanship guarantee

Plumber feeding a CCTV drain camera into an outdoor inspection point

Blocked drains

From $180

Slow sinks, gurgling toilets, smells out the gully — usually a partial blockage that gets worse. We clear it and find out why, so it doesn't come back next month.

We run a CCTV camera through the line first, then jet with high-pressure water if needed. Tree roots, wet wipes, collapsed clay pipe — we'll show you on the screen what's going on and recommend a fix. Camera inspections start at $180.

If a section needs replacing or relining, you'll get a fixed quote in writing within 24 hours. No digging up the yard on a hunch.

  • Camera inspection from $180
  • Tree root removal
  • Same-day across the area

Licensed gas-fitter connecting a stainless gas cooktop in a kitchen benchtop

Gas fitting

Cooktop swap, oven install, new BBQ point or a hot water gas line — gas work has to be done by a licensed fitter, full stop. Ollie holds the gas-fitting authorisation and is on every gas job we run.

Every job ends with a certificate of compliance, which is what you need for insurance and for selling the property. We'll test the line, check appliance pressure and tag the work properly.

If you smell gas, leave the property and call us straight away on 0448 883 109.

  • Certificate of compliance
  • Licensed gas-fitter on every job

Plumber replacing a mixer tap cartridge at a bathroom basin

Tap and toilet repairs

From $165

Dripping mixer, toilet that runs all night, kitchen tap that's lost pressure — small jobs that waste a lot of water. Most are sorted in one visit.

We carry common cartridges, washers, inlet valves and flush mechanisms on the van, so there's usually no second trip. Callout starts from $165 and you'll get a fixed price before we touch a spanner.

If a tap or cistern is past the point of repair, we'll tell you straight and quote a replacement instead of dragging it out.

  • Most jobs done same-day

Plumber using a thermal imaging camera against a bathroom wall to locate a leak

Leak detection

Damp patch on a wall, water bill that doubled, tile that's gone hollow — there's a leak somewhere and you need to know where before anyone starts breaking things.

We use thermal imaging and acoustic equipment to pinpoint leaks behind walls, under slabs and in roof spaces. It's non-invasive, so we're not pulling up tiles to look.

You get a written report with images, suitable for an insurance claim. From there we can repair the leak or hand the report to your builder.

  • Non-invasive thermal imaging
  • Insurance-report-ready findings

If you're standing in water right now, turn off the mains at the meter and call 0448 883 109.
