When 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 inspector's focus will vary considerably based on the property's age, as this significantly impacts the potential issues that may surface.
Quick Summary: For older homes, a pre-purchase inspection aims to uncover age-related concerns, including structural movement, past repairs, outdated electrical and plumbing systems, and signs of termite activity.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 builds focus on the quality of workmanship, identifying any defects or shortcuts taken during construction. Both types of inspections adhere to the Australian Standard (AS 4349.1), but the inspector's focus will differ depending on 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) serving Brisbane and the Moreton Bay region. Below, we detail the key differences between these two types of inspections.

Key Inspection Focus Areas in Older Homes
Older homes possess a unique history, often hiding costly surprises. A building inspection for an established property prioritises the effects of time and any renovations or repairs carried out over the years:
- Structural Movement — Issues such as cracking, uneven flooring, and concerns with footings and subfloors that may develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, worn flashing, and repairs that were addressed superficially rather than properly rectified.
- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their useful life.
- Moisture and Drainage — Issues like rising damp, inadequate drainage, and water pooling in unsuitable locations.
- Termite History — Previous damage and conditions that favour termite infestations, often associated with older timber structures and established gardens.
Essential Inspection Checks for New Builds
A newly constructed home is generally expected to be defect-free; however, many fail to meet this standard. The inspection for a new build focuses on the quality of workmanship and the completeness of the construction rather than age, highlighting common errors that can occur on busy building sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades’ work that have 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 do not drain effectively.
- Incomplete Work — Tasks left unfinished at the time of handover, requiring follow-up once you have moved in.

Consistent Standards with Different Focus in Inspections
Both types of inspections adhere to AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard mandates a thorough visual examination of the property's condition. The differentiation lies in focus: for older homes, the emphasis shifts to assessing the effects 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.
Understanding the Importance of Pest Inspections
In Brisbane, obtaining a pest inspection is wise, regardless of the property’s age. Subterranean termites are common in the area, and new constructions are not immune. Factors such as newly landscaped sections, 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 a single visit. If you are uncertain, consider which inspection is most relevant to your situation.
