Independent inspection to AS 4349.1 by a registered building contractor. What you are buying, read by someone who has built. Report within 24 hours.
A pre-purchase building inspection in Walliston reads a 1970s or 1980s home on the Kalamunda horticultural slope, at higher altitude and under greater scarp rainfall than the Orange Grove scarp-base below it. The inspection is building scope only, to AS 4349.1, and the Walliston pre-purchase read adds the altitude weathering and the former horticultural terrace drainage to the standard age profile — because the building envelope at Walliston's altitude ages faster than coastal equivalents, and the terrace drainage from former stone-fruit and vegetable cultivation can still direct subsurface moisture in unexpected ways.
The altitude weathering read is the most Walliston-specific pre-purchase concern for external materials. Paint, fixings and seals on the weather-facing facades of 1970s-1980s Walliston homes have been under a wetter and more thermally variable regime than coastal homes of the same age. The pre-purchase assessment of those external materials accounts for the altitude weathering rate rather than the coastal standard.
The former horticultural terrace drainage and the Darling Range Regional Park eastern boundary are noted as the site-specific contexts alongside the standard age reads. The combined building and pest inspection is recommended. The report follows within 24 hours.
We run the same inspection across the area, including nearby Orange Grove and Carmel.

A building inspection to AS 4349.1 at Kalamunda scarp altitude, combining the standard 1970s-1980s age profile with the altitude weathering read on external materials and the former horticultural terrace drainage context.
No, building scope only. The combined inspection is recommended given the former horticultural soil and the Regional Park eastern boundary.
Paint, fixings and seals on weather-facing facades at Walliston's altitude are under a wetter and more thermally variable regime than coastal homes of the same age. The pre-purchase assessment accounts for this accelerated external weathering rate.
Stone-fruit and vegetable cultivation on the slopes left terrace drainage that may still direct subsurface moisture unexpectedly beneath residential lots. We note this where identifiable from the observed drainage behaviour.
Eastern lots near the park carry native jarrah and marri — the food source and elevated scarp moisture that elevates termite conditions above the interior of the suburb.
1970s-1980s at 35 to 52 years: wet-area waterproofing at or past first service life, tile mortar at the replacement window, original timber windows at their scarp-altitude thermal cycle count.
Yes. Altitude weathering findings and the age-specific condition findings give you a factual pre-purchase basis.
Yes. Former horticultural soil, elevated scarp moisture and the Regional Park boundary. The combined inspection is recommended.
Yes. Subfloor moisture and drainage management on the horticultural slope are part of the pre-purchase read.
Within 24 hours of the inspection.
