Postans’ #1 Rated Building and Pest Inspection
Postans takes its name from George Postans, a settler who arrived in the colony as a convict and bought 100 acres here in 1882, in an area formerly known as Caledonia. Little of that farming history remains today. The suburb is effectively unpopulated and now given over to quarries, an alumina refinery tailings pond, a wastewater treatment plant, and the Medina Research Station run by the state’s agriculture department, all served off Thomas Road. It’s a working landscape shaped by decades of quarrying and industrial land use rather than any remaining township.
The three defect categories we see most in Postans commercial and industrial buildings are cracked or heaving slabs and hardstand, corroded roof sheeting and fixings, and fire door and exit compliance issues. Ground disturbed by quarrying and tailings operations nearby can settle unevenly under slabs and hardstand, and older research and industrial buildings on site often carry roof sheeting well overdue for a proper check. Where research or office buildings sit alongside industrial land, fire doors and exit paths need to meet current standards, and that’s easy to overlook on a site that reads as purely industrial.
Postans is a working industrial landscape with a long history behind it, and every building here deserves a proper look before you commit. Our registered builders inspect the structure, roof and slab to AS 4349.1 and AS 4349.3, with your report within 24 hours.
The difference with WA Building Inspections is simple: our inspectors are licensed registered builders (BP104751). Real Builders. Better Inspections. That’s why over 30,000 Perth home buyers have trusted us.
What’s Included in Your Postans Building & Pest Inspection
Comprehensive Pre Purchase Building Inspections
Every Postans inspection is carried out by a licensed registered builder (BP104751), not a generalist with a checklist. We physically access roof voids, subfloors and external structures wherever it’s safe to do so, and we inspect against the building code our inspectors have spent their careers working under. On Postans’s industrial and research buildings, our builder-inspectors check slab and hardstand condition against nearby quarrying and tailings ground disturbance, and assess roof sheeting and fire exit compliance across the site.
Compliant with AS 4349.1–2007.
Termite & Pest Inspection Postans
A full timber pest inspection is included with every combined booking, not bolted on as an upsell. We check for active subterranean termite activity, evidence of past activity, termite conducive conditions, failed or expired chemical barriers, and wood borer activity across the property, fencing and outbuildings.
Postans’s older timber-framed research and industrial buildings can attract timber pests, particularly where garden plantings or old timber structures remain near the research station, and our commercial building and pest inspection checks for activity.
Compliant with Australian Standard AS 4349.3–2010.
Detailed Photo Report
Your Postans report lands in your inbox within 24 hours of the inspection. It’s not a generic template. Every defect we identify is photographed, captioned and explained in plain English with the relevant Australian Standard or NCC clause cited where applicable. You’ll see exactly what the issue is, why it matters, and what it’s likely to cost to remediate. We also include a follow-up consultation call so you can walk through the findings with your inspector before any negotiation or settlement decisions.

Frequently Asked Questions
How much does a commercial building inspection in Postans cost?

We cover Postans, Hope Valley, Mandogalup, The Spectacles, Orelia, Medina and Kwinana Beach and the surrounding industrial and commercial precincts.
What does a building and pest inspection cover?
Our inspectors inspect more than your average inspector. How? We are qualified registered builders, so we go where the others won’t and we detect what the others can’t. Read more about what a full building and pest inspection covers.
How long does a commercial building inspection in Postans take?
It depends on the size and use of the building. A small office or workshop can take a couple of hours, while large warehouses and multi-tenancy sites take longer. We’ll give you a time frame with your quote, and your photo report arrives within 24 hours.
Do I need a termite inspection in Postans?
Yes. Older timber-framed buildings and any remaining garden plantings near the research station in Postans can carry timber pest risk for commercial buyers and tenants. Our commercial building and pest inspection covers timber pests, with your report within 24 hours. See what termite damage looks like.
Which suburbs around Postans do you cover?
We cover all of Postans (6167) and the suburbs around it, including Hope Valley, Mandogalup, The Spectacles, Orelia, Medina and Kwinana Beach. We inspect right across the Peel Region & Rockingham to Mandurah Corridor and the rest of Perth.
Do I need a building inspection before buying or leasing a commercial property in Postans?
It isn’t a legal requirement, but it’s the only way to know what you’re taking on. A commercial building and pest inspection shows the condition of the structure, roof, drainage, services and fire safety items before you commit, and gives you evidence to negotiate on price or lease terms. Tenants should also record the building’s condition at the start of a lease, so they aren’t blamed for existing damage when they leave.
What should I look for when buying or leasing a commercial property in Postans?
If you’re buying or leasing a commercial or industrial property in Postans, check the slab and hardstand for cracking given the quarrying and tailings activity nearby, and look at roof sheeting for corrosion on older structures. Confirm fire doors and exits are compliant, especially on any research or office buildings on the site. Our commercial building and pest inspection covers all of it.
Do you do commercial dilapidation reports in Postans?
Yes. Our commercial dilapidation reports record the condition of a building or site before nearby construction, civil works or a new lease starts, with dated photos of every existing defect. If damage appears later, you have independent evidence of what was already there.
Can you negotiate the price after a building and pest inspection?
Yes. A detailed report with photos and plain-English explanations gives you solid evidence to renegotiate the price or ask the seller to fix defects before settlement. Talk to your settlement agent early, because your building inspection condition has a deadline.
What makes WA Building Inspections different?
Our inspectors are licensed registered builders (BP104751). Real Builders. Better Inspections. We know how a home should have been built, not just how it looks, and we inspect to AS 4349.1 with a full timber pest inspection to AS 4349.3. Every report arrives within 24 hours, with a follow-up call to walk you through it.
Do I need a dilapidation report before works start near my Postans property?
With active quarrying, tailings operations and industrial development in the area, yes. A dilapidation report records your building’s condition before nearby earthworks or construction begins, giving you clear evidence if ground vibration or excavation causes damage. It’s a straightforward way to protect your position in a precinct with this much ongoing industrial activity.
