If 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 focus of the inspection will vary significantly depending on the age of the property, as this has a considerable impact on the potential issues that may be discovered.
Quick Overview: For older homes, a pre-purchase inspection aims to uncover age-related concerns, including structural movement, previous repairs, outdated electrical and plumbing systems, and indications of termite infestations. In contrast, inspections for new builds emphasise the quality of craftsmanship, identifying any defects or shortcuts that may have taken place during construction. Both inspection types adhere to the Australian Standard (AS 4349.1), but the inspector's focus will shift 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 detail the key distinctions between these two types of inspections.

Key Inspection Areas for Older Properties
Older homes possess a unique character, often hiding expensive surprises. A building inspection for a historical property prioritises the effects of time and the renovations or repairs made throughout the years:
- Structural Movement — Problems such as cracks, uneven flooring, and issues with footings and subfloors that can develop over many years.
- Roof Condition — Deterioration of roof tiles or metal, worn flashing, and repairs that were superficially addressed rather than thoroughly rectified.
- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their operational lifespan.
- Moisture and Drainage — Challenges such as rising damp, inadequate drainage, and water pooling in undesirable locations.
- Termite History — Past damage and conditions conducive to termite infestations, commonly associated with older timber structures and well-established gardens.
Essential Inspection Criteria for New Constructions
A newly constructed home is generally expected to be defect-free; however, many do not meet this expectation. The inspection for a new build centres on the standard of workmanship and completion rather than age, highlighting common mistakes that may occur on bustling construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and tradespeople's work that have not been executed to a satisfactory standard.
- Waterproofing — Evaluating wet areas and balconies, where shortcuts may lead to leaks within a year or two.
- Roof and Drainage — Problems such as loose tiles and improperly installed gutters and downpipes that fail to drain efficiently.
- Incomplete Work — Tasks left unfinished at the time of handover, necessitating follow-up after moving in.

Uniform Standards with Different Focus Points in Inspections
Both types of inspections are performed in accordance with AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard necessitates a comprehensive visual assessment of the property's condition. The key difference lies in focus: for older homes, we concentrate on evaluating ageing and past renovations, while for new builds, we scrutinise quality and completeness. In either scenario, you will receive an independent report outlining the actual condition of the property you are considering.
Why a Pest Inspection is Essential
In Brisbane, it is advisable to conduct a pest inspection regardless of the property’s age. Subterranean termites are common in the area, and even new constructions are not immune. Factors such as newly landscaped areas, slab edges, and garden beds adjacent to the house can create favourable conditions for termite infestations. A comprehensive building and pest inspection provides an all-inclusive 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.
