What we look for in Pinjarra, and why it differs from the suburb next door. 75.0 km from the CBD, 18.3 km from the coast, postcode 6208.
Pinjarra is one of Western Australia's earliest colonial settlements. Land was set aside by a ford over the Murray in 1831, and long before that it was, and remains, Bindjareb Noongar country. For an inspector the consequence is a genuine nineteenth century building stock.
Edenvale was built in 1888 of locally fired brick. Liveringa dates from 1885. There is a church consecrated in 1863, an 1896 schoolhouse and an 1895 post office. Buildings of this era pre-date cavity walls and damp proof courses, so rising damp, salt attack on soft brick and decaying lime mortar are the norm rather than the exception, and timber floors need a proper subfloor inspection.
Repairs need the right materials. Modern cement render or impermeable paint on soft brick traps moisture and accelerates decay, which is how well meant maintenance destroys old buildings. Where a property is heritage listed, that listing constrains what can be altered, so advice comes before action.
The other defining fact is the river. The Murray has flooded Pinjarra repeatedly. The winter flood of 1895 undermined the bridge piles, and in bad years residents were ferried across by row boat while others waded. So flood mapping for the specific lot matters, along with floor levels measured against recorded flood heights and physical evidence of past inundation. Tide marks. Replaced flooring. Damp lines in walls.
Modern Pinjarra grew after Alcoa built its alumina refinery in 1974, which brought newer housing and some worker and rental stock alongside the historic core. Establishing which Pinjarra a property belongs to determines everything that follows.
Flood prone river flats and old timber buildings are a difficult combination. Ground that floods stays damp long after the water goes, and alluvial soil holds moisture well.
The nineteenth century buildings sit on timber floors over that ground, so the subfloor is the priority and access is frequently poor. We look for damage in bearers and joists, mud leads on piers and stumps, and ventilation that has been closed off by later work. Rural blocks add outbuildings, fencing, stockyards and retaining, all timber in ground contact. Where a property runs to acreage the inspection needs to be scoped clearly, because a barn is not incidental to a rural purchase.
On an old building, damp is the common cause of most of what both inspections find. The moisture rotting a bearer is feeding the colony beside it, and the flood history explains both. Doing the building and timber pest inspections in one attendance is also simply practical when the property is an hour from Perth. Reported under AS 4349.1 and AS 4349.3.
Heritage buildings generate expert witness work, usually where a repair has gone wrong or a dispute has started over what was permitted. We also do dilapidation reports, which matter for old masonry near any construction or heavy vehicle route.
Newer estate housing around the town brings the standard new build services. Building stage inspections during construction, practical completion inspections at handover, and the follow up before the defect liability period expires. Pre-settlement inspections apply to everything, old and new.
Pinjarra sits on the Pinjarra Plain — alluvium of varying age washed off the scarp, ranging from sand to heavy clay over short distances. Site classification varies more here than anywhere else on the plain, sometimes within a single street. Two houses a hundred metres apart can sit on quite different ground, so the cracking on one tells you very little about the other.
What that means in practice, on a house in Pinjarra:
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.
St John's Church and Fairbridge Chapel are the fixed points in Pinjarra. 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.
Ravenswood, South Yunderup, North Yunderup and Barragup sit on the same ground as Pinjarra, 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.
Furnissdale is 12.4 km away but sits on the Spearwood dune system; Coodanup is 14.5 km away but sits on the Spearwood dune system. 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 18.3 km from the coast, out in Mandurah, the inland setting changes what the fee buys in Pinjarra: footing and slab movement, drainage and the reactive soils of the Mandurah belt come first, and coastal delignification is a lower priority away from the arterial corridors. Pinjarra is 75.0 km from the Perth CBD, out toward the Peel end of the area, and the flat fee still applies with no distance loading.

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 18.3 km inland, Pinjarra 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.
