What we look for in Wilson, and why it differs from the suburb next door. 8.9 km from the CBD, 14.4 km from the coast, postcode 6107.
Wilson was farmland until after the Second World War. Then it filled quickly. Then it went up quickly. Six hundred houses were built between 1959 and 1964, many of them State Housing Commission homes. That concentrated batch is the key to the suburb.
Six hundred houses in five years means a large body of near identical stock reaching the same milestones at the same time. That is useful. The defects recur predictably, and knowing the standard build of the era tells us where to look before arriving.
At around sixty five years old, expect services either original or into a first replacement that is itself now ageing. Asbestos era materials are likely in wall and eaves sheeting. Wet area waterproofing is well past a second cycle. Roof fabric and roof plumbing deserve attention.
The Canning River runs along the suburb, and the Kent Street Weir has operated since the 1920s. It was built to stop salt water pushing up the river in summer, and it only partly succeeded, which tells you something about the water here. River flat blocks carry a high water table, flood context and subfloor damp.
Wilson also has a substantial Curtin University rental share, so expect deferred maintenance on tenanted homes and informal sharehouse conversions to check for approval. Being on the river rather than the coast, salt and delignification are a low priority.
The rental share is the local factor worth spelling out. Tenure beats age. In an owner occupied house a dripping tap or a blocked gutter gets dealt with. In a long term rental it can run for months, because the tenant reports what affects daily life and the owner responds to what they are told.
Slow persistent leaks are what turn an ordinary property into an attractive one, and by the time anything shows the damage is done. Sharehouse conversions add wet areas plumbed by whoever was cheapest, concealed behind new linings.
River flat ground supplies the moisture. Sixty five year old gardens hold buried timber and old stumps. Original barriers stopped working decades ago and, given how much of this stock has been tenanted rather than owner occupied, very few have been renewed since.
Access is a real argument on tenanted property, because arranging entry around a tenant is the awkward part of any inspection here. Doing it once for both assessments rather than twice saves genuine time and goodwill. Reported under AS 4349.1 and AS 4349.3.
A lot of Wilson changes hands as an investment rather than a home, so the final inspection before settlement earns its keep. A furnished, occupied house and an empty one can look like different properties.
Infill on the old State Housing lots brings staged inspections during construction and a handover check at completion. Where an older house sits beside that work, a condition record beforehand protects your position.
Ask for the approval history on any house that has been carved into rooms. Floor plans get updated after the fact, and what a diagram shows is not evidence that anyone signed it off.
Wilson 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 Wilson:
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.
Queens Park is the fixed point most people in Wilson 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.
Ferndale, Waterford, Cannington, Bentley, Shelley and Riverton sit on the same ground as Wilson, 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.
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 14.4 km from the coast, out in Kalamunda, the inland setting changes what the fee buys in Wilson: 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 14.4 km inland, Wilson 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:
