What we look for in Wembley, and why it differs from the suburb next door. 4.4 km from the CBD, 5.2 km from the coast, postcode 6014.
Wembley sits on the Spearwood dunes with Tamala Limestone underneath. Free draining sand on top, hard irregular rock below. Lake Monger is on its edge and Herdsman Lake lies just past its northern boundary. Ground and water explain most of what we find here.
Limestone close to the surface shapes how footings were formed and means some older houses are founded directly on rock. It also makes any future excavation awkward and expensive, which is worth knowing before you plan a pool or an extension. Bearing can vary noticeably across a single block.
Water is the other half. Blocks running down toward either lake sit on low ground with a high and seasonally variable water table. That is where drainage struggles, where subfloor damp appears and where slab edges stay wet. A comfortable February inspection can give a flattering impression of a block that behaves quite differently in August, and we say so when the signs are there.
The suburb is also changing shape. Apartment buildings are steadily replacing older houses, so inspections split between mid century stock, with its asbestos era materials and long superseded services, and recent medium density strata that shares almost nothing with it. Establish which you are looking at first.
Mid century houses here were built when Wembley was still an outer suburb, and many have been extended once or twice since. Those additions are worth tracing. An extension done in 1975 was built to the standards of 1975, and the junction where it meets the original house is usually where the trouble starts.
Proximity to two large wetlands raises termite pressure, because moisture is the limiting factor for subterranean colonies and here it is abundant. Reserve and lake margins hold plenty of habitat, and the established gardens of a mature suburb provide the rest.
On the older houses we concentrate on the subfloor and the perimeter. Vents blocked by paving or raised beds, damp from decades of reticulation, buried timber and old stumps left in place, and any garden bed built against the wall base. On slab built houses the risk moves to the slab edge, weep holes covered by soil or paving, and timber in ground contact around decks and retaining. Barriers installed before the mid 1990s no longer do anything.
Where a property sits on damp ground the two inspections are effectively one investigation. Moisture drives both the building problems and the pest risk, and they show up in the same places. Doing both in one attendance gives you a single account of how water moves around and under the house, reported to AS 4349.1 for the building and AS 4349.3 for timber pests.
The apartment and townhouse redevelopment brings strata inspections, off the plan practical completion inspections and a steady demand for dilapidation reports, because if a site next door is being excavated on limestone your house has a direct interest in a dated record of its condition.
We also do building stage inspections for owners building new on subdivided lots, where site classification and how the slab deals with variable limestone bearing are the things that matter most. Pre-settlement inspections apply to everything.
Wembley sits on Spearwood dune sand over Tamala limestone, and the limestone near the surface changes how footings were formed: rock, variable bearing, and awkward excavation for any new work, with older homes sometimes founded directly on it. Free-draining sand above and hard, irregular rock below is a specific combination worth understanding before extending or underpinning a Wembley house, and it is one of the defining ground facts of the suburb.
Two major wetlands sit against Wembley, Lake Monger on its edge and Herdsman Lake beyond its northern boundary, so blocks toward the lakes sit on low ground with a high, seasonally variable water table, and that is where drainage problems, subfloor damp and slab-edge moisture show up. Apartment buildings are progressively replacing older houses, so inspections split between early-to-mid-century houses and recent medium-density strata; establishing which matters, since they share almost no common ground, and near redevelopment a dilapidation record is worth having. The older stock of the 1930s-60s (the Wembley Hotel dates from 1932) carries asbestos-era materials and original services and roof fabric at or past a second cycle. A Wembley inspection reads the sand-over-limestone footings, the lake-edge water table, the house-versus-strata split, and the aged older fabric.
On a Wembley home the ground and the water are read together. Where the Tamala limestone runs near the surface the footings may bear onto rock or sit on the sand above it, so we read any cracking against that variable support and note the awkward excavation new work would face. Toward Lake Monger or the Herdsman side the subfloor and slab edge are checked for the high, seasonal water table, and the site drainage is traced on the lower ground. On an older 1930s-60s home the services and wet areas are end-of-life items and asbestos-era materials are noted, while on the newer apartment stock the inspection establishes the strata picture and reads the concrete, membranes and balconies instead.
None of it is guesswork. Reading the stock above into an inspection, these are the checks the Wembley pattern pushes to the top of the list:
Wembley 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 Wembley:
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.
Wembley Hotel is the fixed point most people in Wembley 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.
West Leederville, Subiaco, Glendalough, Jolimont, Leederville and Daglish sit on the same ground as Wembley, 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.

5.2 km inland through Stirling, the salt risk in Wembley is real but secondary. The same fee weighs an older roof for corrosion alongside the wet areas, the drainage and the movement patterns the Stirling stock tends to show.

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.
Wembley is 5.2 km from the coast — outside the highest-exposure band, but close enough that salt-driven delignification is worth checking in an older tiled roof.
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:
