What we look for in Stratton, and why it differs from the suburb next door. 18.7 km from the CBD, 25.0 km from the coast, postcode 6056.
Stratton was formerly known as Wexcombe, and the current name was chosen in 1989. It was largely developed from the late 1980s, which makes it essentially an estate suburb, sitting at the foot of the Darling Scarp a few kilometres east of Midland.
The name change is worth a practical note. Records, titles and older documents may still refer to Wexcombe, and that catches people out when tracing approvals.
A late 1980s estate at the foot of the scarp is a particular combination. The buildings are consistent. The ground underneath them is not, because this is exactly where plain soils give way to laterite and granite.
So identical houses on the same street can be sitting on different material, and that is where movement comes from more often than workmanship does.
At thirty five years the housing is arriving at its first significant round of replacements. Roof fixings and gutters. Hot water systems. Shower waterproofing reaching the end of what it was designed for.
At the foot of the scarp, ground shifts between coastal plain soils and granite and laterite over short distances. That variation is real and it means footing behaviour is not consistent across the suburb, so cracking should be read with the ground in mind.
Bushland and reserve pockets sit on the scarp side, which brings a bush edge to some blocks with the fire and vegetation considerations that carries.
The scarp-side bushland is the reservoir. Retained vegetation there holds established colonies, and blocks along that edge feel it in a way the western streets do not.
Ground works against the suburb in one direction and for it in another. Laterite and gravel drain freely. Plain soils lower down hold water after rain and reticulation, and hold it longer.
Every barrier here went in within a few years of every other. All of them have run their course, and on housing that has changed hands once or twice very few were replaced.
Thirty five years of garden has built up against wall bases and buried the slab edge under paving and a patio on most of these houses. That is the junction we most need to see and it is routinely the one covered.
Establishing what a Stratton block is founded on serves both reports, and it is one judgement rather than two. The perimeter and the roof space follow from there. Reported under AS 4349.1 and AS 4349.3.
In a suburb this consistent, ask the neighbours what has already needed doing. On houses built to one specification within a few years, those answers apply broadly and they cost nothing to obtain.
Where a block adjoins bushland, buyers usually want that boundary considered specifically, since fire and pest exposure arrive on the same line. Thirty five year old stock is now generating renovation, so staged inspections while a wall is open are worth booking rather than an inspection once everything has been closed up and lined.
Stratton sits on the laterite foothills of the Darling Scarp — lateritic gravel and clay over granite, with rock close to the surface and real slope. Slope is the defining feature. Cut and fill, split levels, and retaining walls are normal here rather than exceptional, and retaining is where the money goes wrong. Rock near the surface also means surface water runs rather than soaks.
What that means in practice, on a house in Stratton:
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.
Swan View Senior High School is the fixed point most people in Stratton navigate by. Buildings like it are useful to an inspector for a duller reason: they date the area. Whatever era put that up is usually the era that put up the houses around it, and the construction methods of that decade are what we expect to find in the roof.
Swan View and Jane Brook sit on the same ground as Stratton, 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.
Middle Swan is 1.6 km away but sits on the Guildford Formation; Midvale is 1.9 km away but sits on the Guildford Formation; Midland is 3.1 km away but sits on the Guildford Formation; Viveash is 3.4 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 25.0 km from the coast, out in Kalamunda, the inland setting changes what the fee buys in Stratton: footing and slab movement, drainage and the reactive soils of the South East belt come first, and coastal delignification is a lower priority away from the arterial corridors.

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 25.0 km inland, Stratton 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:
