Building Inspections in Alkimos, Perth

Alkimos is one of Perth's youngest suburbs. Serious residential development only began in the early 2000s after the State Government partnered with developers on the Shorehaven and Trinity master-planned communities. The first lots were titled around 2006 and the suburb's population reached over 13,000 within fifteen years. Almost all the housing stock is post-2005, engineered concrete slabs, double-brick veneer, and Colorbond or concrete-tile roofs in consistent estate patterns. Alkimos sits on deep yellow Swan Coastal Plain sand over Tamala Limestone. The sand is highly permeable and drains well, but it provides limited lateral support to slab edges and its moisture content varies significantly between wet winters and dry Perth summers. That seasonal variation drives the slab movement and settling cracks that appear even on homes three to five years old. The proximity to the Indian Ocean, most estate lots are within two kilometres of the beach, adds salt aerosol exposure that accelerates corrosion of exposed metal elements. In Alkimos, we see a lot of: - Construction defects in new builds: volume builders on tight margins produce inconsistent workmanship. Common findings are inadequate waterproofing at shower bases and alfresco areas, non-compliant fall on balcony drainage, and silicone gaps at junction points. Typical repair: $1,500–$8,000 depending on scope. - Sandy soil foundation settling: engineered slabs on deep sand continue to move for several years post-handover as the sand re-distributes under load and seasonal moisture cycles. Settlement cracks at window corners are normal for the age but need documenting before purchase. Typical repair: $800–$3,500. - Poor builder finish quality: misaligned tiling grout lines, paint finish defects on eaves and fascias, and incomplete landscaping drainage connections are the three most common cosmetic-to-functional defects in our Alkimos reports. Typical repair: $500–$2,500. The Alkimos railway station opened in July 2024. The station precinct is now zoned for medium-density development, and a wave of strata townhouses is beginning to appear near the station. These bring a different inspection focus: shared-wall waterproofing, balcony drainage, and strata common area conditions.

Every SURE inspection in Alkimos covers structural, moisture, roof, drainage, and timber pest scope. In a suburb this young the focus shifts to construction quality rather than age-related decay. In our 49 Alkimos inspections, the three most common findings are external wall cracking due to settlement, concealed slab edges that present termite entry risk, and trees planted too close to the dwelling. New-build settling on deep sand is predictable within the first five years. Inspectors also check that downpipes are connected to stormwater and that garden mulch is not banked against the brick base course, both of which are frequent short-cuts in estate landscaping.
