What we look for in Spearwood, and why it differs from the suburb next door. 18.3 km from the CBD, 1.8 km from the coast, postcode 6163.
Spearwood was one of Perth's major market gardening areas, famous enough for its onions that they carried the suburb's name. Croatian and Dalmatian migrants have farmed here since 1911, and the community they built is still visible in the clubs and centres across the suburb.
That migrant market gardening history produced a distinctive housing stock. Many homes here were owner built by families who worked the gardens, and owner built does not mean poorly built. It often means solidly built, sometimes to a standard well beyond the era. Not always to conventional detailing.
So the job is establishing what was actually done rather than assuming a standard construction. Additions and outbuildings went up over decades, frequently by the owners themselves, and tracing what was approved matters more here than in a suburb of project homes.
Underneath sits the Spearwood dune system, sand over Tamala Limestone with the limestone close to the surface in places. That affects how footings were formed, brings rock into any excavation, and means the oldest homes may sit on limestone rather than concrete.
Many blocks are former market garden ground, which can hold old irrigation lines, bores, made ground and a long history of horticultural chemical use. Near Fremantle and the Sound, salt is a genuine consideration, so delignification is worth checking in older tiled roofs.
Former horticultural ground is the specific local exposure. Buried, and invisible. Decades of market gardening leave irrigation lines that still leak, buried timber from trellising, shed bearers and yard structures, and soil that has been kept artificially damp for a very long time.
Cleared does not mean removed. Buried timber decaying under a house built in the 1970s is invisible from the surface and is precisely what a subterranean colony establishes on.
Owner built additions add concealed junctions that a conventional house does not have, and where they were built without standard detailing an inspector has to work out the construction rather than rely on familiarity. Limestone footings on the oldest stock weather into voids that give concealed routes to the timber above. Barriers on anything of age here are long finished.
On a house that has been extended by its owners over decades, both inspections depend on first establishing what the building is. Doing that once, then assessing structure and timber against it, is more coherent than two visits forming separate views. Reported under AS 4349.1 and AS 4349.3.
Ask the vendor what the family built and when. They usually remember. In a suburb with this history the owners frequently know exactly, and it is the most useful information anyone can hand an inspector.
Market garden lots are subdividing, so we do condition records for the original house when a new dwelling goes in behind, handover inspections on the new build, and assessments of the older outbuildings that often come with these blocks and rarely appear on any plan. Those sheds are frequently substantial and just as frequently undocumented.
Spearwood sits on the Quindalup dune system — young calcareous sand, still mobile in places, and thin over the water table near the front. Sand this young has low bearing capacity but very little reactivity, so footing movement is uncommon and drainage problems are not. What the ground gives you here it takes back in the air.
What that means in practice, on a house in Spearwood:
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.
Manning Park is the fixed point most people in Spearwood 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.
North Coogee, Hamilton Hill, Coogee and Lake Coogee sit on the same ground as Spearwood, 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.
Coolbellup is 3.1 km away but sits on the Spearwood dune system; Yangebup is 3.2 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.

At 1.8 km from the water, Spearwood sits inside the coastal-salt band — the band where coastal salt drives the defects. The fee concentrates on delignified battens, corroded ties and fixings, and the salt staining that starts inside the masonry, with the roof space taking the longest on a tiled roof past its first decade.

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.
Spearwood is 1.8 km from the coast, inside the band where delignification should be expected in tile battens. On a tiled roof more than about ten years old it is one of the first things we look at.
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:
