Why does my 1970s Duncraig house keep getting leaks?

Original copper in houses this age can wear thin and pinhole, and one leak is often followed by another in the same run. We find and fix the leak, then tell you honestly whether it looks like a one-off or a sign the run is due for replacement.

Do tree roots cause blocked drains in Greenwood and Warwick?

Often, yes. Older clay sewer pipes have joints that roots can get into, and the mature trees in these suburbs have had decades to do it. We clear the blockage and can check the line so you know what you’re dealing with.

How long does it take to get to Duncraig from Ellenbrook?

It’s a cross-north run on Reid Highway and the freeway. Time depends on where we are and the traffic, so we give a real ETA when you ring, and planned jobs get a booked window.

Can you replace a hot water system in Kingsley or Padbury?

Yes. Tell us whether it’s gas or electric, where it sits and how tight the access is. Many homes here are on their second or third unit, and we’ll explain what the replacement involves before we start.

Plumber in Duncraig, Greenwood, Warwick and Kingsley

Most of Duncraig was built in the mid-1970s between Marmion Avenue and the Mitchell Freeway, and Greenwood, Warwick, Kingsley, Woodvale and Padbury filled in around the same years — so the original copper, hot water units and sewer laterals across this belt are now around fifty years old.

The short answer

Yes, McDermott Plumbing covers Duncraig, Greenwood, Warwick, Kingsley, Woodvale and Padbury for licensed plumbing and gas: burst pipes, blocked drains, hot water repairs and replacements, leak detection and gas fitting. Call (08) 6187 3999 or text 0406 882 648. From Ellenbrook it’s a cross-north run via Reid Highway and the freeway — we give a real ETA before you wait.

A 1970s belt between the freeway and Marmion Avenue

Duncraig’s primary schools and library opened in 1974–75, which tells you when most of its houses went up. Padbury was named in 1971 and built out over the following years. Warwick keeps a big piece of native bush — the Warwick Open Space covers roughly its eastern third — and Woodvale is split by the Yellagonga wetlands, with a small slice still in the City of Wanneroo. In practice that means established brick-and-tile homes, mature backyard and verge trees, and pipework that has done its time. From Ellenbrook we come across on Reid Highway; we tell you how long it will be rather than promise a blanket time.

What we see around Duncraig

Fifty-year-old suburbs have their own set of repeat jobs:

Duncraig and Greenwood: original copper supply lines that start to pinhole, usually showing up as a damp patch, a hissing wall or a water bill that jumps for no reason.
Clay or early earthenware sewer laterals with tree roots at the joints — big gums and figs have had decades to find them. Slow drains and a full overflow relief gully are the first signs.
Warwick: homes backing onto the Warwick Open Space and other reserves, where roots and shifting sand affect buried pipes more than on open estates.
Woodvale near the Yellagonga wetlands: softer, damper ground around the lake edge; buried poly between the meter and the house can move and leak.
Padbury and Kingsley renovations: older bathrooms and laundries being redone, with the old pipe left behind the new tiles — we check what’s worth replacing while the wall is open.
Second- or third-generation hot water units on outside walls, often squeezed into tight side access between fence and house.

Blocked drains on older northern homes

If the toilet gurgles, the shower drains slowly or the gully is overflowing, the blockage is usually in the property sewer between the house and the Water Corporation connection. That part is the owner’s responsibility. We clear it and tell you if the pipe looks cracked or root-invaded so you can decide between repair and occasional clearing. If the problem is in the Water Corporation main, we report it and their crew clears it. Sewage overflowing on the property: call Water Corporation on 13 13 75 as well as us.
