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 vital. The inspector's focus will differ significantly depending on the property's age, as this has a considerable impact on potential issues that might arise.
Quick Summary: For older properties, a pre-purchase inspection aims to uncover age-related concerns, including structural movement, past repairs, outdated electrical and plumbing systems, and signs of termite activity. In contrast, inspections for new constructions focus on assessing the quality of workmanship, identifying any defects or shortcuts taken during the building process. Both types of inspections adhere to the Australian Standard (AS 4349.1), yet the inspector's priorities will shift based on the age of the property.
At Zoom Building & Pest Inspections, we provide assessments for both older and new properties, operating as a QBCC-licensed company (QBCC licence 15279880) serving Brisbane and the Moreton Bay region. Below, we detail the key differences between these two types of inspections.

Key Inspection Focus Areas for Older Properties
Older homes carry a distinct history and may hide expensive surprises. A building inspection for an established property emphasises the effects of time and the renovations or repairs that have been made over the years:
- Structural Movement — Issues such as cracking, uneven flooring, and concerns with footings and subfloors that can develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, worn flashing, and repairs that were addressed only superficially rather than being properly rectified.
- Outdated Services — Aging electrical and plumbing systems that may be approaching the end of their useful life.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 well-established gardens.
Essential Inspection Considerations for New Constructions
A newly constructed home is typically expected to be free of defects; however, many fail to meet this standard. The inspection for a new build centres on the quality of workmanship and completion rather than age, revealing common errors that may arise on busy construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades’ work that have not been executed to a satisfactory level.
- 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 do not drain effectively.
- Incomplete Work — Tasks left unfinished at the time of handover, requiring follow-up after moving in.

Uniform Standards with Distinct Focus in Inspections
Both inspection types are conducted in accordance with AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard mandates a comprehensive visual examination of the property's condition. The distinction lies in focus: for older homes, the emphasis is on evaluating aging and past renovations, while for new builds, we scrutinise quality and completion. Regardless of the property’s age, you will receive an independent report detailing its actual condition.
Recognising the Significance of a Pest Inspection
In Brisbane, obtaining a pest inspection is advisable 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 favourable 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, contemplate which inspection is most relevant to your situation.
