If you are contemplating the purchase of a charming brick-and-tile home from the 1970s in the inner suburbs or a modern property in one of Brisbane's rapidly transforming areas, arranging a pre-purchase inspection is crucial. The inspector's attention will shift significantly depending on the property's age, as this greatly impacts the potential issues that may be uncovered.
Quick Overview: For older residences, a pre-purchase inspection aims to detect age-related problems, including structural movement, previous repairs, outdated electrical and plumbing systems, and indications of termite activity. In contrast, inspections for new constructions focus on workmanship quality, highlighting any defects or shortcuts that may have occurred during building. Both inspections adhere to the Australian Standard (AS 4349.1), but the inspector's focus will vary depending on the age of the property.
At Zoom Building & Pest Inspections, we conduct assessments for both older and new properties as a QBCC-licensed company (QBCC licence 15279880) serving Brisbane and the Moreton Bay region. Below, we detail the significant differences between these two types of inspections.

Key Areas of Focus in Inspections for Older Homes
Older homes come with a distinct history, often hiding unexpected and costly surprises. A building inspection for an established property prioritises the impact of time and any renovations or repairs that have occurred over the years:
- Structural Movement — Problems such as cracking, uneven flooring, and issues with footings and subfloors that may develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, damaged flashing, and repairs that were superficially addressed rather than properly rectified.
- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their useful life.
- Moisture and Drainage — Concerns such as rising damp, insufficient drainage, and water accumulation in inappropriate areas.
- Termite History — Previous damage and conditions that may encourage termite infestations, often associated with older timber structures and established gardens.
Essential Inspection Criteria for New Builds
A newly constructed home is typically expected to be free from defects; however, many do not meet this expectation. The inspection for a new build concentrates on the quality of workmanship and overall completion rather than age, revealing common mistakes that can arise on bustling construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and work by tradespeople that has not been completed 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 effectively.
- Incomplete Work — Tasks that remain unfinished at the time of handover, requiring follow-up after moving in.

Consistent Standards with Different Emphases in Inspections
Both types of inspections are conducted following AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard mandates a comprehensive visual assessment of the property's condition. The distinction lies in focus: for older homes, the emphasis is on evaluating age and past renovations, while for new builds, we scrutinise quality and completion. In either scenario, you will receive an independent report detailing the true condition of the property you are considering.
Why a Pest Inspection is Crucial
In Brisbane, securing a pest inspection is advisable irrespective of the property's age. Subterranean termites are common 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 favourable conditions for termite infestations. A combined building and pest inspection provides a thorough overview of both the property's condition and potential timber pest threats, all during a single visit. If unsure, consider which inspection is most relevant to your situation.
