Whether you are contemplating the purchase of a charming 1970s brick-and-tile home in the inner suburbs or a modern property in one of Brisbane’s rapidly developing areas, obtaining a pre-purchase inspection is crucial. The inspector's areas of focus will vary considerably depending on the property's age, as this significantly affects the potential issues that may be encountered.
Quick Overview: For older properties, a pre-purchase inspection aims to uncover age-related concerns, which include structural movement, past repairs, outdated electrical and plumbing systems, and indications of termite activity. In contrast, inspections for new constructions concentrate on the quality of workmanship, identifying any defects or shortcuts that may have occurred during the building process. Both inspection types adhere to the Australian Standard (AS 4349.1), but the inspector's focus will change according to the property's age.
At Zoom Building & Pest Inspections, we provide assessments for both older and newer properties as a QBCC-licensed company (QBCC licence 15279880) operating in Brisbane and the Moreton Bay region. Below, we detail the primary differences between these two inspection types.

Key Areas of Focus for Inspections of Older Homes
Older homes possess a distinctive history and may hide unexpected and costly surprises. A building inspection for an established property prioritises the effects of time and any renovations or repairs conducted over the years:
- Structural Movement — Problems like cracking, uneven flooring, and issues with footings and subfloors that can develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, failing flashing, and repairs that were superficially addressed rather than properly resolved.
- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their operational life.
- Moisture and Drainage — Problems like rising damp, poor drainage, and water accumulation in unsuitable areas.
- Termite History — Previous damage and conditions that could lead to termite infestations, often associated with older timber structures and well-established gardens.
Essential Inspection Considerations for New Constructions
While a newly constructed home is typically expected to be free of defects, many fail to meet these expectations. The focus of the inspection for a new build is on the quality of workmanship and project completion, highlighting common mistakes that can arise on busy construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades’ work that remains uncompleted to a satisfactory standard.
- Waterproofing — Evaluating wet areas and balconies where shortcuts may result in leaks within a year or two.
- Roof and Drainage — Problems such as loose tiles and improperly installed gutters and downpipes that do not function effectively.
- Incomplete Work — Tasks that remain unfinished at the time of handover, requiring follow-up after taking possession.

Uniform Standards with Distinct Focus in Building Inspections
Both inspection types are performed in accordance with AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard mandates a thorough visual assessment of the property's condition. The key distinction is in focus: for older homes, the emphasis lies on evaluating ageing and previous renovations, while for new builds, we examine quality and completion. Regardless of the property type, you will receive an independent report detailing the actual condition of the property you are considering.
Why a Pest Inspection is Essential
In Brisbane, undertaking a pest inspection is recommended regardless of the property’s age. Subterranean termites are widespread in the area, and new constructions are not immune. Factors such as newly landscaped areas, slab edges, and garden beds adjacent to the home can create ideal conditions for termite infestations. A combined building and pest inspection provides a comprehensive assessment of both the property's state and potential timber pest threats, all during a single visit. If you are uncertain, consider which inspection is most relevant to your situation.
