The short answer
Yes, McDermott Plumbing covers Landsdale, Darch and Madeley for licensed plumbing and gas: hot water repairs and replacements, blocked drains and toilets, burst pipes and leaks, leak detection and gas fitting, for homes and for the light industrial units in Landsdale. Call (08) 6187 3999 or text 0406 882 648. It’s a run west from our Ellenbrook base rather than a trip across Perth, and we’ll give you a real ETA when you ring.
From market gardens to Cell 6
Landsdale used to cover a much bigger area, reaching west to Wanneroo Road. When the East Wanneroo Development Area was set up in 1996, Cell 6 was marked as a high priority and split into a western and an eastern section. After some back and forth with the Geographic Names Committee (the City’s first choice, Kingsway, was rejected as too close to Kingsley), the two halves were named Madeley and Darch in 1998, after early settler families.
Building took off from 2001. Madeley grew fast enough for a property magazine to estimate its growth at 33% a year in 2007, and at the 2016 census it had 2,274 dwellings, most of them detached houses on single lots. Landsdale is the mixed one of the three: housing around Landsdale Gardens, plus commercial and light manufacturing areas, and new schools are still opening, with Landsdale Gardens Primary starting in 2023.
What we see around Landsdale, Darch and Madeley
Houses of the same age tend to wear out in the same ways, and this belt is a good example:
- Hot water on the outside wall. Many homes here have a gas storage or continuous-flow unit mounted outside, often down a narrow side path. Units from the first building wave are now on, or coming up to, their first replacement. When we swap one, we also check the gas connection, the tempering valve and whether the old position still makes sense.
- Blocked drains from what goes down them. Homes built from 2001 are a lot newer than Perth’s older sewer lines, so the blockages we clear here are more often wipes, fat and grease than roots. Water Corporation still says a hairline crack is all a root needs, and every house here is now past the 15-year age it flags as higher risk.
- Original flexi hoses, isolation valves and mixer cartridges that have done twenty-plus years under sinks and in showers: drips, low flow at one tap, and the odd sudden leak.
- Light industrial and commercial units in Landsdale: staff amenities, blocked toilets and after-hours leaks. Tell us about access, alarm codes and any site rules when you book.
- High water bills with nothing obviously leaking. A cracked pipe between the meter and the house can leak into sandy ground for months without showing on the surface. Our leak detection page explains the meter test.

Common questions
- Which suburbs does this page cover?
- Landsdale, Darch and Madeley. Girrawheen, Koondoola, Marangaroo and Alexander Heights have their own page, and so do Wanneroo and Duncraig. Ballajura is on our Ellenbrook-side area pages. If you’re not sure, call (08) 6187 3999 with the street.
- How far is Landsdale from your base?
- It’s a run west from Ellenbrook, not a cross-city trip, but the ETA still depends on where we are and the traffic when you ring. We’ll give you a real time rather than a guess, and planned jobs get a booked window.
- Our gas hot water unit on the outside wall is leaking. Repair or replace?
- It depends where the water is coming from. A dripping relief valve or a leaking fitting can often be fixed. Water coming from the tank itself usually means it’s time to replace it. Turn off the gas at the unit and the cold water to it if it’s safe to, then call. Our hot water leaking page explains what to check.
- Do you work on Landsdale industrial and commercial units?
- Yes, for licensed plumbing and gas on small commercial and light industrial units: leaks, blocked amenities, hot water and gas connections. Tell us about access hours and who should get the invoice.
- Our house is only twenty-odd years old. Why is the drain blocking?
- In newer homes it’s usually what goes down it: wipes, fat and grease in the kitchen line, or hair in the shower waste. Roots can still get into a cracked pipe or a loose joint. We clear it and tell you what we found, so you know whether it’s likely to come back.
