What we look for in Dalkeith, and why it differs from the suburb next door. 7.6 km from the CBD, 3.4 km from the coast, postcode 6009.
Dalkeith is Perth's most expensive suburb and it has water on three sides. Both facts change what an inspection here has to cover, and neither of them in the way people expect.
The money shows up as scale. Houses are large and often custom built. Multi storey, usually. Pools, extensive glazing, roof geometry that takes a while to work out. Many have a basement or a lower ground level, and that is the item that matters most. Below ground rooms depend entirely on their tanking and waterproofing, which is unforgiving work. When it fails the repair is disruptive and expensive, and the damp usually appears some distance from where the water actually got in.
The river makes that worse. Riverside blocks carry a high water table and estuarine damp working at masonry, plus retaining and river wall structures that come with the property. A basement three streets back from the water is a different proposition to one on the foreshore, and it is worth knowing which you are buying.
Land value at this level drives knock down rebuild, so 1930s houses stand beside very recent large ones. It is worth saying plainly that price does not guarantee build quality. The finishes on a new prestige home are usually excellent. The waterproofing, drainage and roof detailing behind them still need checking, and we find problems in expensive houses regularly.
Big blocks with established gardens are good termite country. Mature trees. Old stumps and buried roots. Years of garden beds pressed against the house. All of it helps a colony get going long before anything reaches the structure. Reticulation running through summer keeps the soil damp against footings.
Then there is the landscaping that comes with money. Raised planters against walls. Paving built up over the slab edge. Pool surrounds, decking, timber retaining. Each one can bridge a termite barrier or conceal the junction an inspector needs to see. On a house with a basement, damp below ground and timber framing above it make for an unhappy combination, and any subfloor or service void deserves proper attention rather than a glance through a hatch.
On a large house the practical argument is simply time. Getting through a multi storey home with a basement and a pool takes a while, and that is before the outbuildings and the grounds. Doing it twice makes no sense. One attendance covers structure and timber pests, reported under AS 4349.1 and AS 4349.3. It also means one person forms a single view of how water is behaving on the site, which on a riverside block with below ground rooms is the question that matters most.
Rebuilds are constant here, so building stage inspections are worth having while a large custom home goes up. Waterproofing, tanking and drainage get covered over early and cannot be checked later without opening things up. Practical completion inspections at handover matter for the same reason.
Dilapidation reports are common because demolition and excavation next door are routine in these streets, and a neighbouring basement dig is exactly the situation where a dated record of your own house is worth having. We also do pre-settlement inspections and expert witness work, the latter more often than average because the sums involved make disputes worth pursuing.
Dalkeith sits on the Spearwood dune system — residual yellow and grey sand over a Tamala Limestone core, with the rock often close to the surface. Limestone near the surface makes for stable footings and expensive excavation. Where the rock is shallow, older houses often sit directly on limestone footings, and those are the ones to look at for rising damp and salt damp at the base of the wall.
What that means in practice, on a house in Dalkeith:
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.
Nedlands, Crawley and Attadale sit on the same ground as Dalkeith, 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.
Claremont is 2.3 km away but sits on the Quindalup dune system; Peppermint Grove is 3.0 km away but sits on the Quindalup dune system; Cottesloe is 3.4 km away but sits on the Quindalup 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 3.4 km from the water, Dalkeith 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.
Dalkeith is 3.4 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:
