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.
Karrinyup sits on the elevated limestone country between the coast and the lakes, wrapped around its golf course and its recently rebuilt shopping centre. The housing is a mix of established mid-century homes and large modern rebuilds, and two things shape a building and timber pest inspection here: the limestone the suburb is built on, and the elevation, because Karrinyup's rises carry retaining, drainage and, on the better blocks, ocean glimpses that come at a structural price.
The limestone ground is the first factor. Homes are often founded on or cut into limestone, so the inspection reads the footings for undermining where water tracks through the porous rock, and the base masonry for the salt and moisture attack limestone suffers near the ground. On the elevated blocks, levels are held by retaining walls, and those are read for bulging and drainage behind the wall, and whether they were engineered for their height, because a tall retaining wall on a Karrinyup slope is a serious structure, not a garden feature.
Being near the coast, Karrinyup gets a real dose of salt air, less than the beachfront but enough to matter, so exposed metal, roof fixings and flashings are read for corrosion, and on the large modern homes the glazing and rendered facades are read for their weatherproofing in that setting. The mid-century homes are read for their era: asbestos in eaves and sheeting, brittle tiled roofs and delignified framing, all flagged for what they are.
Karrinyup is a strong knockdown-rebuild market, so the inspection often meets a large recent build, where the read is build quality: wet-area waterproofing to AS 3740 and any flat-roof detailing, the retaining and drainage the elevated block demands, and the finishing a fast build rushes. Where a home is bought to replace, the inspection focuses on the site and what is being retained.
On the timber pest side, the free-draining limestone means less standing moisture, but the mature, watered gardens of the established streets create their own damp reservoirs, and the older timber offers a path in. The subfloor and perimeter are read for conducive conditions, and suspect timber sounded, with movement detection where a gallery is suspected behind a wall. Termite management follows AS 3660.
Karrinyup is an elevated, coast-adjacent, limestone suburb of mid-century homes and big rebuilds, and the report earns its value by reading the ground, the retaining and the salt exposure together, because on these blocks they set the terms.
We run the same two-scope visit across the area, including nearby Trigg and North Beach.

Homes here are often founded on or cut into limestone. We read the footings for undermining where water tracks through the porous rock, and the base masonry for the salt and moisture attack limestone suffers near the ground. It is a genuine structural factor on these blocks.
They do. On the elevated blocks, levels are held by retaining walls, and we read those for bulging, drainage behind the wall and whether they were engineered for their height. A tall retaining wall on a Karrinyup slope is a serious structure, not a garden feature.
A real one, less than the beachfront but enough to matter. We read exposed metal and roof fixings and flashings for corrosion, and on the large modern homes we read the extensive glazing and rendered facades for their weatherproofing in the salt air.
Yes, in eaves and sheeting. We identify and flag suspect materials without disturbing them, which matters most if you plan to renovate or replace.
The focus shifts to build quality: wet-area waterproofing to AS 3740 and any flat-roof detailing, the retaining and drainage the elevated block demands, and the finishing a fast build rushes. A pre-handover look while the builder is liable is worth as much as a pre-purchase one.
Often. Mid-century tiles are brittle with perished sarking, and the hardwood framing can show chemical delignification, which reduces what it can carry. We read the roof closely and probe for it.
On the elevated blocks, yes. We read retaining for bulging and cracking, the drainage behind it, and whether it was built for its height, because a failing retaining wall on a slope is both a safety and a cost issue.
Yes, though the free-draining limestone means less standing moisture. The mature, watered gardens of the older streets create their own damp reservoirs, and older timber offers a path in. We read the subfloor and perimeter and sound suspect timber, with movement detection where needed. Termite management follows AS 3660.
A flat $616 including GST for both scopes together, the same in every suburb. A large home on an elevated block takes time to read properly, and you have the written report, with photos, within 24 hours.
Yes. A clear report separates the significant issue, failing retaining or limestone footing undermining, or corrosion, from the cosmetic, and gives you a concrete basis to renegotiate.
