What we look for in Aveley, and why it differs from the suburb next door. 22.7 km from the CBD, 22.7 km from the coast, postcode 6069.
Aveley is a masterplanned community developed through the 2000s and 2010s, established in 2006 and grown to around fourteen thousand people. It is named after a town in Essex and after the family who owned the land. It sits on the Ellen Brook flats.
Almost everything here is 2000s and 2010s stock, so the defects are early life rather than end of life. Slab and footing performance. Roof plumbing and flashing detail. Wet area waterproofing that was done recently enough to still be the original builder's work.
The ground is the thing that makes this suburb specific. Ellen Brook flats mean alluvial and reactive clay soils with a water table near the brook, and reactive clay moves seasonally regardless of how well a house was built.
So slab on clay performance is the structural question. Cracking should be read against the season it appears in rather than taken at face value, and drainage that keeps moisture even around a perimeter matters more here than on sand, because differential wetting is what drives differential movement.
The estates include narrow lot and higher density housing, which brings zero lot walls, close boundaries and drainage that has to work in the gap between two buildings. Access for future repair is restricted on those lots.
Far inland, so salt and delignification are not the story. Clay and water are.
Reactive clay does two things that matter. It holds water rather than draining it, so ground beside a house stays damp longer after rain or reticulation. And when it dries it cracks, and those cracks give concealed access toward a slab edge or footing that would otherwise be plainly visible.
Ellen Brook supplies moisture on the blocks nearest it.
Every home here was built with a termite management system and should carry a durable notice recording it. On the earliest stages that system is now approaching the end of its useful life, so find the notice and check the date rather than assuming a recent house is still protected.
Then look at the perimeter, because in an estate where everyone landscaped within a few years of handover, soil and paving over the slab edge is normal.
Drainage on reactive clay underpins both reports here, so one inspector answering that question once serves each. Reported under AS 4349.1 and AS 4349.3.
On clay, the useful inspection is often the one booked before the defect liability period expires rather than after. Slab movement takes a season or two to show. That window closes quietly.
Continuing development brings handover inspections and condition records where a finished house sits beside a lot about to be built on. On narrow lots those records matter more, since the works will be a metre or two from your wall and arguing about damage afterwards without a dated record is close to impossible.
Ask which stage of the estate a house belongs to. On clay, a few years between builds can mean different slab design.
Aveley sits on the Guildford Formation — alluvial clay and sandy clay laid down by the Swan and Canning systems. This is the reactive ground. Clay here shrinks and swells with moisture, which is what puts stepped cracking through brickwork and takes doors out of square between seasons. Articulation joints matter on these sites, and a great many older houses do not have them where a current standard would want them.
What that means in practice, on a house in Aveley:
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.
Ellenbrook, Belhus, The Vines, Henley Brook, Upper Swan and Brabham sit on the same ground as Aveley, 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 22.7 km from the coast, out in Swan, Aveley 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 22.7 km inland, Aveley 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:
