What we look for in Sorrento, and why it differs from the suburb next door. 17.4 km from the CBD, on the coast, postcode 6020.
Sorrento was surveyed as a private freehold subdivision in 1929 and named after the Italian seaside town. Patrick Marmion ran a whaling station here in 1849, with remains at the surf club site. Fishermen built boatsheds and shacks through the 1930s, and residential settlement only began in the early 1950s.
Seventy years of construction methods sit in this one suburb. Date it first. Original 1950s homes, the dense settlement of the 1970s through early 90s, modern renovations, and brand new apartments. Dating a property is the necessary first step because those categories share very little.
What is changing the suburb now is density. The Sorrento Activity Centre Plan allows R80 medium and high density along West Coast Drive and Raleigh Road, with three to five storey apartments and a seven storey project opposite Hillarys. So a growing share of inspections here are strata, where concrete, waterproofing membranes, balconies and common property matter more than anything inside the lot.
On a coastal apartment building, concrete condition is the headline. Salt reaching reinforcement causes spalling, and that sits in common property and reaches every owner through levies. Read what the scheme has spent and what it has put off.
The older houses sit on coastal dune sites facing the Marmion Marine Park reef coast, with ocean frontage and heavy salt. Delignification is a genuine check on any original tiled roof.
Coastal dune sand keeps general termite pressure low, and in the apartment stock it is lower still. The exposures are specific.
On the older houses, timber in ground contact around retaining, decking, pergolas and fencing is the main route, and salt air shortens the life of all of it so replacement happens in stages. Reticulation creates damp pockets in otherwise free draining sand.
In the new apartment and townhouse stock the exposure moves to ground floor courtyards, planter boxes and landscaping sitting against structure. Podium planters above occupied space keep soil permanently damp and are usually a waterproofing question before they are a pest one. In strata, termite management generally rests with the scheme, so ask what exists and when it was last checked.
For an older house the roof and the external timber serve both inspections. For an apartment, one set of access arrangements through a strata manager saves genuine time. Either way, one attendance. That is the practical choice. Reported under AS 4349.1 and AS 4349.3.
With R80 infill active, find out what is approved for neighbouring land before buying. A three to five storey building next door changes a property permanently and the planning position is public information.
New apartment stock brings handover inspections and the follow up before builder liability expires, which closes quietly and takes your rights along with it if nobody is watching. Condition records matter for older houses beside apartment construction. We also prepare reports where water ingress in a coastal building has become a dispute, which on this coast is a recurring theme.
Sorrento spans about seventy years of construction in one suburb, from early-1950s homes through 1970s stock to brand-new apartments, so the era of the actual dwelling drives the inspection and has to be established rather than assumed. Layered on top of that is active R80 high-density infill of three to seven storeys, which means a growing amount of new apartment stock: concrete, membranes, balconies and common property, so a meaningful share of Sorrento inspections are strata inspections rather than houses, with the concerns that brings.
The setting is coastal dune sites on the Marmion Marine Park reef coast, so dune stability, retaining and drainage matter on the sloping blocks, and the ocean frontage brings heavy salt onto the older tiled roofs, making delignification a genuine first-look item there. Establishing whether you are inspecting an early-50s house, a 70s home, or new medium-density strata, and reading the coastal exposure accordingly, is the core of a Sorrento inspection. The seventy-year span and the high-density infill are what make it varied.
Which of Sorrento's seventy years of stock a house belongs to sets the inspection, so its era is established first. On an early-50s or 70s home the checks are age-appropriate services, roof and wet areas; on the new R80 apartment stock the inspection reads concrete, membranes, balconies and the common-property picture that strata brings. The coastal dune sites are read for stability, retaining and drainage where there is slope, and the ocean frontage drives the salt checks: wall ties, exposed metal, gutters and flashings, with any older tiled roof getting a batten look for delignification. Establishing house versus strata early matters here, because the two are entirely different inspections on the same street.
None of it is guesswork. Reading the stock above into an inspection, these are the checks the Sorrento pattern pushes to the top of the list:
Sorrento 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 Sorrento:
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.
Geneff Park and Sorrento Activity Centre are the fixed points in Sorrento. 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.
Marmion, Hillarys and Watermans Bay sit on the same ground as Sorrento, 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.
Duncraig is 2.2 km away but sits on the Spearwood dune system; Glengarry is 2.6 km away but sits on the Spearwood dune system; Padbury is 3.4 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.

Right on the coast in Stirling, in postcode 6020, the fee here is spent chasing salt. Chemical delignification in the tile battens, wall ties rusting inside the cavity, fixings going to lace where the sea air reaches them — on an older tiled roof the roof space is where most of the inspection time lands.

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.
Sorrento is on 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:
