What we look for in Kensington, and why it differs from the suburb next door. 4.0 km from the CBD, 11.0 km from the coast, postcode 6151.
Kensington started out as a weatherboard suburb. Timber, not brick. Most of its early houses were timber, not brick, and that gave it what people at the time called a working class image. Some residents minded enough to petition the Road Board to have the suburb declared brick only. They did not get their way. The timber stock is still here.
A timber framed, timber clad house on stumps is a different inspection from a masonry one. The subfloor carries the structure, so stumps, bearers, joists, ventilation and moisture all get looked at directly. Cladding and its junctions matter, particularly at the base where boards meet the ground and at any point water is directed by a gutter or a downpipe.
One question is worth asking specifically in Kensington. Was brick veneer or render applied later over an original timber frame? It happens, and it changes how the wall handles moisture, because the timber behind is now enclosed. We check what the wall is really made of rather than what it looks like from the footpath.
A second layer arrived in 1951, when a block bounded by George, Douglas, Oxford and Dyson Streets went to the State Housing Commission. That produced consistent post-war housing, now around seventy years old, with asbestos era materials and services well past their life. The suburb also straddles two councils, so confirm which one holds the approval records before relying on them.
Timber framed houses on stumps sit at the higher end of termite risk in Perth. The structure itself is food, the subfloor gives access and cover, and any moisture down there speeds everything up. This is the suburb where a thorough subfloor inspection earns its fee.
We look for mud leads on stumps and piers, damage in bearers and joists, moisture from leaking wet areas overhead, and vents that have been covered by paving, garden beds or later additions. Kensington Bushland forms a reserve edge on one side, and bushland raises local pressure. Old barriers are long dead. Where a timber house has been reclad or rendered, termites can work inside a wall with nothing visible from either side, and that is worth knowing before you buy rather than after.
For a timber house the two inspections are almost the same physical exercise. The inspector is under the floor either way, looking at the same bearers, in the same light, with the same torch. Splitting that across two visits duplicates the awkward part and risks two different accounts of the same subfloor. One attendance covers both, reported to AS 4349.1 for the building and AS 4349.3 for timber pests.
Character timber houses attract renovation, so we do stage inspections and practical completion inspections on extensions and rebuilds. Where an old house is being restumped or reclad, having someone independent look at the work while it is open is worth more than looking at it once it is closed up.
Infill and unit development around the fringes brings strata work and dilapidation reports, the latter particularly if you own a timber house next to a site about to be excavated. Pre-settlement inspections apply across the board.
Kensington 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 Kensington:
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.
Kensington Park and Durbridge Hall are the fixed points in Kensington. 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.
Victoria Park, South Perth, East Victoria Park, Burswood, Bentley and Como sit on the same ground as Kensington, 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.

11.0 km inland through South Perth, Kensington 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 11.0 km inland, Kensington 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:
