If you are contemplating the purchase of a charming 1970s brick-and-tile home in the inner suburbs or a modern residence in one of Brisbane's rapidly changing neighbourhoods, arranging a pre-purchase inspection is vital. The inspector's focus will vary considerably depending on the property's age, which greatly impacts the potential issues that may be uncovered.
Quick Overview: For older properties, a pre-purchase inspection aims to uncover age-related problems such as structural movement, past repairs, outdated electrical and plumbing systems, and evidence of termite activity. In contrast, inspections for new constructions focus on craftsmanship quality, identifying any defects or shortcuts taken during the building process. Both inspection types adhere to the Australian Standard (AS 4349.1), yet the inspector's focus will change based on 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) serving Brisbane and the Moreton Bay region, we detail the key distinctions between these inspection types below.

Key Focus Areas for Inspections of Older Homes
Older homes possess a distinctive history and often hide expensive surprises. A building inspection for an established property prioritises the impact of time and any renovations or repairs made over the years:
- Structural Movement — Problems such as cracking, uneven flooring, and issues with footings and subfloors that can develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, worn flashing, and repairs that have been 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- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their operational life.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 — Issues such as rising damp, inadequate drainage, and water pooling in unsuitable locations.
- Termite History — Past damage and conditions favourable for termite infestations, often associated with older timber structures and established gardens.
Essential Inspection Checks for New Builds
A newly constructed home is expected to be defect-free; however, many do not meet this standard. The inspection for a new build centres on workmanship quality and completion rather than age, revealing common mistakes that may occur on busy construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades' work that have not been completed to an acceptable 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 fitted gutters and downpipes that do not drain effectively.
- Incomplete Work — Tasks that remain unfinished at handover, requiring follow-up after moving in.

Uniform Standards with Distinct Focus in Inspections
Both inspection types are carried out in accordance with AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard mandates a meticulous visual examination of a property's condition. The difference lies in the focus: for older homes, the attention is on assessing age-related issues and past renovations, while for new builds, the scrutiny is on quality and overall completion. In both instances, you will receive an impartial report detailing the actual condition of the property you are considering.
The Necessity of a Pest Inspection
In Brisbane, obtaining a pest inspection is advisable, regardless of the property's age. Subterranean termites are prevalent in the area, and new constructions are not immune. Factors such as newly landscaped areas, slab edges, and garden beds adjacent to the house can create ideal 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 best suits your circumstances.
