What we look for in Greenwood, and why it differs from the suburb next door. 15.1 km from the CBD, 4.9 km from the coast, postcode 6024.
Greenwood was launched in 1969 and built out from 1970, so its housing is around fifty five years old. Two later events changed the suburb, and both matter when you are buying here.
Start with age. Houses from around 1970 are into second cycle territory for roofing, plumbing and wiring. Original wet areas are long past their working life. Decades past. Despite sitting roughly five kilometres inland the suburb is rated high risk for delignification, so the timbers under an original tile roof deserve a proper look rather than a glance from the manhole.
Now the two events. The Mitchell Freeway was cut through the reserve on the suburb's edge in 1985 and 1986, well after the houses were built. Homes along that eastern boundary were never designed or oriented with a freeway in mind, so traffic noise and vibration there is a retrofitted condition. Check the glazing and any noise treatment that has been added, and be realistic about how much can practically be improved.
The second event was the closure of the original Greenwood Primary School in 1997, when its land was subdivided and sold as house lots. That created a pocket of much newer homes embedded inside 1970s streets. Two properties a hundred metres apart can be a quarter century apart in age. Work out which you are looking at first, because everything else follows from it.
Fifty five year old gardens are the main driver. Half a century of growth. Buried timber with it. Old stumps left in the ground, buried sleepers, disused form-work, and beds banked against the wall base have had decades to become established. Reticulation running every summer keeps soil damp against footings.
Original chemical barriers from the 1970s stopped working long ago, whatever the paperwork says. Many of these houses have never had another. Where the house sits on a slab the focus is the perimeter, weep holes buried by garden beds or paving, and the slab edge that a patio or addition has covered. The ex school site housing is a different case entirely, being modern construction with a documented termite management system, so find the durable notice and check whether the landscaping since has bridged it.
In a suburb of fifty year old houses the two inspections keep meeting in the same places. The roof space where delignification shows is the roof space where termite workings show. The damp along a wall base that concerns a pest inspector is the damp that has been rotting a bearer. Booking them together gets one attendance and one account of the house, reported under AS 4349.1 and AS 4349.3.
Older stock on decent blocks means renovation and subdivision, so building stage inspections and practical completion inspections come up on new builds behind original houses. Where a block beside you is being developed, a dilapidation report records your condition before the work starts.
We also do pre-settlement inspections, which matter on a fifty year old house because the gap between acceptance and settlement is long enough for problems to appear or be covered up. Strata inspections apply to the units near the freeway and the shopping centre.
Greenwood's defining quirk is that the Mitchell Freeway was cut through in 1985-86, after the suburb was built, so homes along the eastern edge were never designed or oriented for freeway proximity. Traffic noise and vibration on those streets is a retrofit condition, so on near-freeway blocks we look at glazing, wall construction and any noise treatment, and a buyer should be realistic about what can be improved. There is also a pocket of markedly newer homes to watch for: the original primary school site was subdivided and sold as house lots in the late 1990s, creating later infill embedded within 1970s streets, and establishing whether a property is original estate stock or school-site infill matters because they inspect completely differently.
The bulk is early-1970s estate stock with tile roofs, rated HIGH for delignification despite sitting around five kilometres inland, so roof-timber condition deserves proper attention on unrenewed roofs. Homes from around 1970 are now roughly fifty-five years old, which is second-cycle territory for roofing, plumbing and wiring, and original wet areas are well past their life. A Greenwood inspection reads the freeway-retrofit exposure on the eastern edge, sorts original stock from school-site infill, and leads with the roof space given the delignification rating on the fifty-five-year-old tile roofs.
On an original 1970s Greenwood home the roof space leads, read for the delignification the HIGH rating makes likely on an unrenewed tile roof despite the inland position, with the tile fixings and pointing checked alongside. The services are read as second-cycle items on fifty-five-year-old stock: switchboard and wiring, hot water, and wet areas whose original waterproofing is well past its life. On the eastern near-freeway streets the glazing and wall construction are read for how the retrofitted freeway proximity is handled, and any noise treatment assessed. And where a property is late-1990s school-site infill rather than original estate stock, the inspection shifts to that newer stock's first-cycle and build-quality checks instead.
Greenwood 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 Greenwood:
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.
The ORIGINAL Greenwood Primary School is the fixed point most people in Greenwood 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.
Kingsley, Warwick, Glengarry, Madeley, Duncraig and Hamersley sit on the same ground as Greenwood, 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.

At 4.9 km from the water, Greenwood 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.
Greenwood is 4.9 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:
