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 changing neighbourhoods, arranging a pre-purchase inspection is crucial. The inspector's focus will differ significantly based on the property's age, which greatly affects the range of potential issues that may be present.
Quick Overview: Pre-purchase inspections for older homes are aimed at uncovering age-related issues such as structural movement, past repairs, outdated electrical and plumbing systems, as well as indications of termite activity. In contrast, inspections for new constructions concentrate on the quality of workmanship, identifying any defects or shortcuts that may have occurred during the building process. Both inspection types adhere to the Australian Standard (AS 4349.1), yet the inspector's focus will vary depending on the property's age.
At Zoom Building & Pest Inspections, we provide evaluations for both older and newer properties. As a QBCC-licensed company (QBCC licence 15279880), we proudly serve Brisbane and the Moreton Bay region. Below, we detail the significant differences between these two types of inspections.

Key Inspection Areas for Older Homes
Older homes carry a unique history and often hide expensive surprises. A building inspection for an established property prioritises the impact of time along with the renovations or repairs made over the years:
- Structural Movement — Issues like cracking, uneven flooring, and concerns regarding footings and subfloors that may develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, worn flashing, and repairs that have been superficially addressed rather than properly rectified.
- Outdated Services — Aging electrical and plumbing systems that might be nearing the end of their functional lifespan.
- Moisture and Drainage — Concerns such as rising damp, insufficient drainage, and water pooling in inappropriate areas.
- Termite History — Previous damage and conditions favourable to termite infestations, often associated with older timber structures and established gardens.
Essential Inspection Focus for New Builds
A newly constructed home is typically expected to be free from defects; however, many do not meet this standard. The inspection for a new build concentrates on the quality of workmanship and completion, highlighting common errors that can occur on busy construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades’ work that have not been executed to an acceptable standard.
- Waterproofing — Evaluation of wet areas and balconies, where shortcuts might 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.

Uniform Standards with Focused Inspection Areas
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 difference lies in focus: older homes require an assessment of aging and previous renovations, while new builds are scrutinised for quality and completion. Regardless of the property type, you will receive an independent report detailing the actual condition of the property you are contemplating.
Why You Should Consider a Pest Inspection
In Brisbane, obtaining a pest inspection is wise 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 conducive conditions for termite infestations. A combined building and pest inspection provides a comprehensive assessment of both the property's condition and potential timber pest threats in one visit. If you are uncertain, consider which inspection is most relevant to your situation.
