What we look for in East Cannington, and why it differs from the suburb next door. 11.3 km from the CBD, 18.9 km from the coast, postcode 6107.
East Cannington was paddocks. Farms and horse agistment, with only the strip near the railway used for housing, until developers moved in during the 1990s. Before that it held a jam factory set up by the Taylor brothers in the 1920s, a garment manufacturer, and two dairies.
Four former operations in a small suburb. Where housing now stands on any of those sites the ground history is a fair question. The records exist.
Ask what a parcel was before it was a house. Someone will know. It is not an accusation, it is due diligence, and the answer changes how movement in a slab should be read.
The 1990s conversion from paddocks means most housing here is thirty years old or less, on ground that was cleared and filled at subdivision. Where a slab has moved, that preparation is the first thing to consider rather than workmanship.
A small amount of early fabric survives near the railway. Weatherboard shops, among them. So genuinely old buildings sit among the newer stock, and they share nothing with it. Establish which you are dealing with before anything else.
The suburb is bounded by the Armadale line and Welshpool Road, so perimeter properties carry transport noise and heavy vehicle movement.
Horse agistment ground is the specific local exposure and it is invisible now. Paddocks mean fence lines, yards, shelters and feed structures, all timber set into soil across large areas, and when land is subdivided those timbers are pushed over rather than dug out.
Dairy and factory sites add their own buried material, and imported fill from the 1990s subdivision can contain almost anything.
Buried timber decaying quietly under a modern estate house is exactly what a subterranean colony establishes on, and nothing about it is visible from the surface.
On the housing itself, thirty year old stock carries a barrier that has reached the end of its useful life, with a durable notice recording what was installed. Find it, then look at what the garden has done to the slab edge since.
Ground history drives both reports here, so establishing what a parcel was serves each of them at once. Reported under AS 4349.1 and AS 4349.3.
On the surviving early buildings near the railway, weatherboard construction needs a subfloor inspection and an asbestos discussion before any renovation is priced. Those two items decide the budget on a building of that type, and both are cheaper to establish than to discover.
Thirty year old estate stock is now generating renovation and subdivision, so staged inspections while a wall is open are worth booking rather than an inspection after everything is closed up and lined. Problems found while a frame is open cost a fraction of what the same problems cost later. Condition records apply where building happens next door. On the rail and Welshpool boundaries sustained vibration makes them more valuable again, since older masonry gives way slowly rather than suddenly and by then the cause is hard to prove.
East Cannington 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 East Cannington:
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.
East Cannington School and Cannington Train Station are the fixed points in East Cannington. 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.
Queens Park, Beckenham and Cannington sit on the same ground as East Cannington, 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.
Kewdale is 2.9 km away but sits on the Guildford Formation; Wattle Grove is 3.2 km away but sits on the Guildford Formation; Kenwick is 3.5 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 18.9 km from the coast, out in Kalamunda, East Cannington 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 18.9 km inland, East Cannington 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:
