Both scopes in one visit — building to AS 4349.1, timber pest to AS 4349.3. The fuller check, by a registered building contractor. Report within 24 hours.
Kalamunda sits on the Darling Scarp at around three hundred metres above sea level, and the landscape that makes it a home in the jarrah forest also shapes the inspection in a way that surprises buyers who think of the hills as simpler ground than the coastal plain. The ridgelines are rock and shallow soil over laterite, stable and well-drained, but the valleys between them hold deep clay, and that clay is reactive, swelling when it is wet and shrinking when it is dry in exactly the way that Perth’s coastal-plain reactive clays do. A building and timber pest inspection at Kalamunda reads for which of those two very different grounds the home sits on.
In the valley positions, the clay is the lead. Deep reactive clay under a footing or slab moves seasonally with the moisture, and the cracking it produces in brickwork and slabs is the same read as a reactive-clay suburb on the coastal plain, except that in the hills the seasonal moisture swing from a wet winter to a hot dry summer can be more dramatic. We read the crack patterns, the fall of floors and the gaps at cornices and door reveals to tell seasonal movement within tolerance from a footing problem that is still working.
On the ridgeline and slope positions, the read is about the terrain itself. A home on a steeply sloping block needs its retaining walls and footings to carry the load and manage the water that runs off the scarp in winter, and we read the retaining walls for movement or failure, the site drainage for where water is and is not being managed, and the subfloor for what the slope does to a home’s underside.
The housing stock ranges from heritage orchard-era cottages from the 1880s and 1890s through to mid-century and modern hills homes on large treed lots. The older cottages earn the age read of their era, original fabric and joinery on a century-old home in a cool, moist hills climate. The newer hills homes earn the modern read, waterproofing and roof plumbing, on sites where the slope and the clay below may matter more than they do in a flat suburban block.
The timber pest side is significant in a forested suburb. Jarrah and marri bushland sit at the perimeter and between blocks, established gardens on large lots give termites cover, and the moist cool valleys are the kind of setting termites use. We read subfloor, roof timbers and the perimeter of the home carefully, and on clay-valley blocks we are especially attentive to the damp that retained moisture in reactive soil can maintain.
What you get is a plain reading of the Kalamunda home on its ground, valley clay or ridgeline, with the report inside 24 hours and the real defects separated clearly from the cosmetic.
We run the same two-scope visit across the area, including nearby Gooseberry Hill and Lesmurdie.

The two very different grounds. The ridgelines are stable rock and laterite, but the valleys hold deep reactive clay that behaves just like coastal-plain reactive clay, swelling and shrinking with the seasons.
Because buyers often assume the hills are simpler ground. Valley positions in Kalamunda can have as much seasonal clay movement as any reactive suburb on the plain, and the hills' wet-to-dry seasonal swing can make it more dramatic.
Through the crack patterns in brickwork and slabs, the fall of floors, and the gaps at cornices and door reveals, to tell seasonal movement within tolerance from a footing problem that is still working.
The read is about terrain: retaining walls carrying the load and managing winter runoff, site drainage, and the subfloor for what the slope does to the underside of a home.
Yes. Original fabric on a century-old home in a cool, moist hills climate is the age read of its era, and the cool dampness means some findings come earlier than they would in a drier coastal suburb.
Yes. Jarrah and marri bushland at the perimeter, large established gardens and moist cool valleys give termites cover and the dampness they use, so we read the subfloor, roof timbers and perimeter carefully.
It can. Reactive clay in a valley holds moisture longer than sandy soil, which sustains the conditions termites prefer, so the valley-position pest read is particularly careful.
Yes. Sloping blocks get a careful read of the retaining structures, the site drainage and the subfloor, because a steep site changes the load and water-management requirements of both.
Yes. The building inspection to AS 4349.1 and the timber pest inspection to AS 4349.3 are done in one visit, with a single report within 24 hours.
