A building inspection in Bunbury needs to account for three things that Perth buyers rarely think about: salt air off the Indian Ocean, a high water table across the low-lying suburbs, and a housing stock that runs from Federation-era timber cottages to brand new estates. The right inspection for a South Bunbury brick and tile home is not the right inspection for a new build in Dalyellup.
Bestwest Building operates within the South West, and this guide covers what our registered builders look for across Greater Bunbury, what a pre-purchase building inspection includes, and how to book one in the window between signing your contract and settlement.

What kind of homes are in Bunbury?
Bunbury grew in rings. The oldest homes sit close to the CBD and the Leschenault Inlet, where timber-framed cottages and inter-war brick homes have been renovated and extended many times over. South Bunbury, East Bunbury, Carey Park and Withers carry the post-war boom, with brick and tile and fibro homes from the 1950s to the 1980s. Glen Iris, Usher and College Grove are 1990s and 2000s brick and tile, and Dalyellup, Eaton and Treendale are where the new estates are.
Each era brings its own defect profile, and an inspector who knows Bunbury knows what to expect before the front door opens.
| KEY TAKEAWAY Renovated older homes are the highest-risk purchase in Bunbury. A new kitchen and fresh paint tell you nothing about the roof frame, the subfloor or the original wiring, and an inspection under AS 4349.1 is visual only, so it cannot assess what is concealed behind new finishes. |
Common defects found in Bunbury homes
Coastal corrosion
Salt-laden air accelerates rust on everything metal. On Bunbury homes within a few kilometres of the coast, inspectors regularly find corroded roof sheeting and screws, rusted gutters, downpipes and valley irons, and corroded lintels. Rust jacking on lintels cracks the brickwork above them, and it shows up as stepped cracking that buyers mistake for movement.
Moisture and rising damp
Parts of Bunbury sit on low-lying, sandy ground with a high water table, particularly around the inlet and the Preston River floodplain. Older homes with subfloor and crawl space areas where accessible often show damp timbers, poor ventilation, fungal decay and salt damp in the lower brickwork. Moisture readings behind shower walls are standard on every Bestwest structural and premium inspection.
Roof cover on 1960s to 1980s homes
Clay tile roofs from this era are now 40 to 60 years old. Spalling, the progressive erosion of the tile surface, is common, along with cracked ridge capping pointing and perished sarking. On sheet metal roofs, coastal corrosion does the same job faster.
Termites and timber pests
The South West is a high-risk termite region, and the older timber-floored homes near the CBD, along with any home with timber in contact with soil, are the most exposed. A combined building and timber pest inspection is the default recommendation for any established Bunbury home.
What does a Bunbury building inspection include?
A pre-purchase building inspection is carried out under AS 4349.1 and covers all visible and accessible building elements: the roof exterior and roof space, external walls and brickwork, internal walls, ceilings and floors, wet areas, and subfloor and crawl space areas where accessible. It is a visual, non-invasive inspection. Gutters and downpipes are visually checked, drainage systems are not tested, and services such as wiring and plumbing are not tested.
Adding a timber pest inspection under AS 4349.3 in the same visit covers active termites, previous damage and conducive conditions. For two-storey homes, a $99 drone add-on captures the roof cover.
| WHY IT MATTERS In WA the inspection is usually carried out after you sign the contract, but before settlement. Settlement is often around 30 days, and because inspection lead times can be up to a week, we suggest booking within about 7 days of signing to give ample time to act on the report. |
Building or buying new in Bunbury?
Bunbury’s new estates in Dalyellup, Eaton, Treendale and Australind are where most of the region’s construction is happening. Bestwest carries out construction progress inspections across all five build stages in the South West: Slab, Brickwork/Framing, Roof Frame, Waterproofing and Roof Cover, and Practical Completion. Homeowners approaching handover can book a standalone practical completion inspection, which comes with a 10 business day rectification window for the builder to address listed defects.
Buying a home that is only a few years old? It still needs an inspection. The findings are different, not fewer, and we covered why in New Build Inspection Perth.
Dilapidation reports for Bunbury properties
With infrastructure and subdivision work continuing across Greater Bunbury, owners near construction sites are increasingly asked for a dilapidation report. It documents the condition of your property before nearby works start, so any cracking or movement that appears later can be attributed correctly.
