Building and structural inspections Perth

Every pre purchase structural inspection and report for a residential building is conducted in accordance with the Australian Standard AS4349.1-2007. This type of structural inspection aims to visually inspect the condition of the property and identify minor defects, major defects, major structural defects and items that may require maintenance. The cost of the inspection is minimal compared to the value it can provide to home buyers. The pre purchase building inspection report is a written account of the property’s condition. It will include any significant building defects or problems such as rising damp, movement in the walls (cracking), safety hazards or a structural concerns in the roof space. It is usually carried out before settlement so that the buyer can identify problems which, if left unchecked, could prove costly to repair. In addition to a building inspection report, we are able to also provide certified structural engineering advice on how to rectify structural defects throughout.  For more information refer to our ultimate guide to pre-purchase structural building inspections for the Perth homebuyer.

While a pre purchase structural inspection report offers some protection in the event that safety hazards, major defects or structural defects are identified, there is often a range of maintenance activities which are not covered by the standard REIWA Offer and Acceptance Contract, or defects that are outside the scope covered by AS4349.1 Pre-purchase inspections – Residential buildings. Examples include fencing that requires replacement, corrosion in non-structural building elements, fretting clay tiles, repointing of tiled roofs and non-structural but difficult to reach wall cracking requiring scaffolding.

We are proud to offer exceptional structural engineering services to homeowners and homebuyers and our costumer experience is at the forefront of our service offering. Our structural engineering expertise enables us to offer more than your standard pre-purchase structural or buildings inspection service. We can assist with various inspections such as roof structure inspections, structural inspections for cracking in house walls, retaining wall inspections, and structural inspections for retrospective council approvals for unauthorised structures such as patios, sheds and retaining walls.  


With our inspection services in Perth, a pre purchase structural inspection will focus on issues that may impact the structural integrity of the building such as the interior walls of the building, the roof space and frame; the exterior walls of the building, piers, columns, posts, and lintels. A pre purchase building inspection for Perth home buyers will concentrate on the structural integrity of the building and will also assess non-structural items such as paving grade, moisture testing of the walls adjacent to the showers, roof cover and all roof penetrations including gutter, downpipes and flashings lintels insulation, sarking and many other non-structural elements. This will provide the home buyer with a good understanding of the items that require maintenance to extend the durability of the non-structural elements.
