Whether you are considering purchasing a delightful 1970s brick-and-tile residence in the inner suburbs or a contemporary property in one of Brisbane’s swiftly evolving neighbourhoods, securing a pre-purchase inspection is essential. The inspector's focus will vary significantly based on the property's age, as this greatly influences the potential issues that may arise.
Quick Summary: For older homes, a pre-purchase inspection is designed to identify age-related concerns, such as structural movement, previous repairs, outdated electrical and plumbing systems, as well as signs of termite activity. Conversely, inspections for new builds concentrate on the quality of workmanship, pinpointing any defects or shortcuts that may have occurred during construction. Both types of inspections comply with the Australian Standard (AS 4349.1), but the inspector's emphasis will differ according to the property's age.
At Zoom Building & Pest Inspections, we offer assessments for both older and new properties, as a QBCC-licensed company (QBCC licence 15279880) serving Brisbane and the Moreton Bay region. Below, we outline the key differences between these two types of inspections.

Essential Inspection Focus Areas for Older Homes
Older homes come with a unique history, often concealing costly surprises. A building inspection for an established property prioritises the effects of time and the renovations or repairs carried out 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 instead of 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- Outdated Services — Aging electrical and plumbing systems that may be approaching the end of their useful life.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 inappropriate locations.
- Termite History — Previous damage and conditions conducive to termite infestations, often linked to older timber structures and established gardens.
Crucial Inspection Checks for New Builds
A newly constructed home is generally expected to be free from defects; however, many fall short of this standard. The inspection for a new build focuses on the quality of workmanship and completion rather than age, shedding light on common errors that can occur on busy construction sites:
- Finishing Defects — Problems related to tiling, painting, gaps, and trades’ work that have not been completed to a satisfactory standard.
- Waterproofing — Assessing wet areas and balconies, where shortcuts may lead to leaks within a year or two.
- Roof and Drainage — Issues 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, necessitating follow-up after moving in.

Consistent Standards with Varied Focus in Inspections
Both types of inspections are conducted in accordance with AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard requires a thorough visual examination of the property's condition. The distinction lies in focus: for older homes, the emphasis is on assessing aging and past renovations, while for new builds, we scrutinise quality and completion. In either case, you will receive an independent report detailing the actual condition of the property you are considering.
The Importance 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 exempt. Factors such as newly landscaped sections, slab edges, and garden beds adjacent to the house can create favourable conditions for termite infestations. A combined building and pest inspection offers a comprehensive overview of both the property's condition and potential timber pest threats, all in one visit. If you are unsure, consider which inspection is most pertinent to your circumstances.
