If you are contemplating the acquisition 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 focus will vary considerably based on the property's age, which significantly impacts the potential issues that may arise.
Key Takeaway: For older residences, a pre-purchase inspection aims to uncover age-related concerns, such as structural movement, previous repairs, outdated electrical and plumbing systems, and indications of termite activity. In contrast, inspections for newly constructed homes emphasise the quality of workmanship, identifying any defects or shortcuts taken during the building process. Both inspection types adhere to the Australian Standard (AS 4349.1), but the inspector's focus will differ according to the property's age.
At Zoom Building & Pest Inspections, we provide evaluations for both older and new properties, as a QBCC-licensed company (QBCC licence 15279880) operating in Brisbane and the Moreton Bay region. Below, we highlight the key differences between these two categories of inspections.

Critical Areas of Focus in Inspections for Older Homes
Older homes possess a distinctive history and often hide expensive surprises. A building inspection for an established property prioritises the impacts of time and the renovations or repairs conducted over the years:
- Structural Movement — Issues such as cracking, uneven flooring, and concerns with footings and subfloors can develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, worn flashing, and repairs that were addressed superficially rather than being properly rectified.
- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their useful life.
- Moisture and Drainage — Issues such as rising damp, inadequate drainage, and water pooling in unsuitable locations.
- Termite History — Previous damage and conditions conducive to termite infestations, often associated with older timber structures and mature gardens.
Essential Inspection Aspects for New Builds
A newly constructed home is typically expected to be free from defects; however, many fail to meet this standard. The inspection for a new build concentrates on the quality of workmanship and completion rather than age, highlighting common mistakes that can arise on busy construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades’ work that have not been executed to a satisfactory standard.
- Waterproofing — Evaluating wet areas and balconies, where shortcuts might 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 drain effectively.
- Incomplete Work — Tasks left unfinished at the time of handover, requiring follow-up after moving in.

Understanding Consistent Standards with Varied Focus in Inspections
Both types of inspections are carried out in accordance with AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard necessitates a thorough visual examination of the property's condition. The primary difference lies in the focus: for older homes, the attention is on assessing the impacts of ageing and past renovations, while for new builds, we scrutinise quality and completion. In either scenario, you will receive an independent report detailing the actual condition of the property you are considering.
Why a Pest Inspection is Essential
In Brisbane, it is advisable to obtain a pest inspection regardless of the property’s age. Subterranean termites are prevalent in the region, and new constructions are not immune. Factors such as newly landscaped areas, slab edges, and garden beds adjacent to the house can create conducive conditions for termite infestations. A combined building and pest inspection provides a comprehensive overview of both the property's condition and potential timber pest threats, all in one visit. If you are uncertain, consider which inspection is most relevant to your situation.
