What we look for in Maddington, and why it differs from the suburb next door. 15.9 km from the CBD, 19.8 km from the coast, postcode 6109.
Maddington carries the oldest name in the Gosnells area. It goes back to the 1830s. John Randall Phillips called his property Maddington Park in the 1830s, after a Wiltshire town, and it was subdivided some seventy years later following the gold rush. The suburb today is genuinely mixed use.
Residential, retail, industrial and semi rural land all sit within the one suburb, and the industrial estate has an unusual origin. Canning Park Racecourse, established in 1868, fell into disuse, and from the 1970s an English developer turned that land into the Maddington Industrial Estate along Albany Highway.
So residential blocks can adjoin industrial land, and the position of a house relative to that boundary matters more than most things about the building. Noise, heavy vehicle movement and operating hours vary street by street. Check the zoning of neighbouring parcels rather than only the one you are buying.
The suburb also retains vineyards and orchards from its agricultural past, along with semi rural pockets. Those bring large lots, septic systems, bores, sheds and former horticultural ground with old irrigation and a century of cultivation behind it.
Ground here is Pinjarra Plain and Canning catchment clay, which is reactive and moves seasonally, so footing and slab movement are ordinary considerations rather than alarming ones. There is transit oriented development around the station bringing newer density. Inland. Salt is a low priority.
Reactive clay behaves in a way that matters for termites as well as footings. When clay dries it shrinks and cracks, and those cracks give concealed access routes toward a slab edge or footing that would otherwise be plainly visible.
Clay also holds water rather than shedding it, so ground beside a house stays damp longer after rain or reticulation than it would on sand.
On the semi rural pockets the exposure spreads across the property. Old orchard and vineyard infrastructure, trellis posts set into soil, sheds sitting directly on the ground, and irrigation that has kept earth wet for decades. On suburban blocks the slab edge and perimeter take priority, with barriers on older stock long finished.
On reactive clay the drainage assessment answers questions in both reports, because how evenly moisture sits around a house governs both movement and pest exposure. One attendance is the sensible arrangement. Reported under AS 4349.1 and AS 4349.3.
The industrial estate means we do commercial work here as well as housing. The two are different jobs. For residential buyers near that boundary, a condition record before nearby works begin is worth having, since heavy vehicle vibration affects older masonry.
On the semi rural parcels, buyers usually want the effluent system, water supply and outbuildings looked at specifically. Around the station, newer density brings handover inspections on recently completed units.
On a semi rural block here, settle the scope in writing first. Which sheds are included and which are not is the thing people assume rather than confirm, and it is the commonest source of argument afterwards.
Maddington sits on the Bassendean dune system — deep leached grey quartz sand, almost pure, and very free draining. Bassendean sand is about as unreactive as a building site gets, so seasonal footing movement is rarely the story here. The water table is the story. Parts of this system sit over the Gnangara Mound and the standing water level can be within a couple of metres of the surface.
What that means in practice, on a house in Maddington:
Landform is assigned from the suburb's position on the Swan Coastal Plain rather than from a site soil test. It tells you what to expect, not what you have. A site classification to AS 2870 is a different exercise and a different report.
Maddington Park and Canning Park are the fixed points in Maddington. They matter to an inspection for an unromantic reason: they date the surrounding stock. The decade that built them is usually the decade that built the houses around them, and that decade decides what is in the roof, what is in the walls, and what the wiring looks like.
Thornlie, Langford, Gosnells and Beckenham sit on the same ground as Maddington, so the footing behaviour and the drainage problems tend to repeat across all of them. If you are comparing houses across those suburbs, you are largely comparing the same site conditions.
Kenwick is 1.9 km away but sits on the Guildford Formation; Orange Grove is 4.1 km away but sits on the Guildford Formation. That is the useful thing about this part of Perth: the ground can change inside a few kilometres, and with it what an inspection is looking for.
On site classification: any soil zone quoted for a suburb is indicative, inferred from geography rather than surveyed. A real AS 2870 classification comes from geotechnical work on your actual block and can differ from the one next door. We report what we observe; we do not read your soil class off a map.
The inspection is visual and non-invasive, over the readily accessible areas, reported to AS 4349.1. Our inspectors physically enter the roof space, as long as there is sufficient access. Report within 24 hours of the inspection.

Well inland at 19.8 km from the coast, out in Gosnells, Maddington is far enough from the water that salt takes a back seat. The same fee goes into footings, drainage and the ground movement typical inland, and the tiled roof is checked for delignification only near heavy traffic.

Yes. Our inspectors physically enter and inspect the roof space, as long as there is sufficient access to do so safely. Where access is restricted, the report says so plainly rather than implying we saw more than we did.
At 19.8 km inland, Maddington carries lower coastal-salt exposure, so delignification is not the first thing we would expect. It remains possible near heavy arterial corridors or industrial emissions.
Within 24 hours of the inspection itself, not 24 hours from booking. On a pre-purchase or pre-settlement job that timing is the whole point, because your leverage disappears once you are committed.
We would rather you checked than took our word for it. These are the bodies that actually hold the records and set the rules:
