Building Inspections in Hammond Park, Perth

Hammond Park sits on Spearwood sand over limestone with reactive clay lenses further inland, a transition geology between the shallow-limestone coastal suburbs to the west and the reactive clay ground further south. That geology means both limestone-ground symptoms and reactive-ground symptoms show up in roughly equal measure, which is unusual in the Cockburn corridor. The estate-era landscaping adds the decisive layer. Most Hammond Park homes were built between the mid-1990s and 2010s, and the trees and gardens planted at handover are now 10-25 years old. As root systems reach the reactive clay lenses beneath the sand, seasonal slab movement accelerates in ways that were not visible when the properties were new. In Hammond Park, we see a lot of: - Trees in close proximity to the dwelling: 55% of reports. Estate-era planting at 1-2 metres from the slab is now root-reach range on reactive ground. This is the single most common finding here and the most direct driver of the structural outcomes below. Typical assessment: arborist consult plus crack monitoring at $600–$2,000. - Concealed slab edges: 48% of reports at severity 3.57 out of 5. The highest average severity of any recurring finding in the Hammond Park dataset. Estate garden beds that have grown up to the brick course eliminate the termite barrier inspection zone on brick-veneer timber-frame construction. Typical remediation: garden rebuild and barrier assessment at $1,200–$4,000. - External wall cracking from slab settlement: 48% of reports. The reactive clay lenses beneath the Spearwood sand respond to root drawdown and seasonal moisture. Most cracking is moderate stepped brickwork, but cases adjacent to trees or with poor stormwater direction can reach severity 4.0+. Typical repair: $1,500–$8,500.

Every SURE inspection in Hammond Park covers the standard structural, moisture, roof, drainage and timber pest scope. What changes is where we spend the extra time. Hammond Park is a 29-report dataset and the findings are heavily weighted toward the classic master-planned-estate profile. Trees in close proximity to the dwelling flag in 55% of Hammond Park reports, the single most common finding, which reflects estate-era landscaping now reaching the size where root drawdown on reactive ground becomes a real structural issue. Concealed slab edges flag in 48% of reports at an average severity of 3.57 out of 5, the highest severity score of any recurring finding in the dataset, because concealed slab edges hide the termite entry path that brick-veneer timber-frame construction is vulnerable to. External wall cracking from slab settlement flags in 48%, and bedroom 2 ceiling cornice joint cracks flag in 48% as the typical telegraphing point where timber-frame movement reads into the finishes. Mulch and garden beds against the house flag in 41% at severity 2.83. Undrained air conditioner overflows flag in 38%, and high termite risk from environmental surrounds flags in 28%. The termite category runs to 21 of 29 reports at an average severity of 3.22, confirming that termite pressure is real and consistent in this transition zone. On the estate-era brick-veneer stock we spend extra time on slab-edge exposure, stormwater direction, and tree proximity that drives both settlement and termite entry, the three findings that together account for most Hammond Park outcomes.
