INSPECTIONS BY REGISTERED BUILDERS
Karnup’s #1 Rated Building and Pest Inspection
Karnup is a big, spread-out suburb of 32.2 square kilometres and only about 2,000 residents, so it feels nothing like the coastal estates just west. The townsite was declared in 1924, and today it’s a semi-rural patch of large blocks, paddocks, bush and a winery, strung along Mandurah Road. Most properties here are lifestyle homes on acreage, with sheds, tanks and long driveways. Long-term, the City of Rockingham has a district structure plan for about 2,000 hectares of future urban growth, with a train station planned, but post-2031 for most of it.
The three defect categories we see most in Karnup properties are unapproved sheds and outbuildings, septic and drainage problems, and termites in bushland timber. Acreage owners build sheds, patios and granny flats over the years, and not all of it has approval or a sound frame. Homes on septic systems and bores need the wet areas and site drainage looked at closely. Mature trees, fence posts and outbuilding timber on big bush blocks are prime termite ground.
Buying a rural block is a different job to buying in an estate. There’s more to inspect, and a lot more to go wrong out of sight. Our registered builders check the house, sheds, verandahs, roof and boundaries, and give you a plain-English report within 24 hours. We also point out where the things to check before buying go beyond the house itself.
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 Karnup Building & Pest Inspection
Comprehensive Pre Purchase Building Inspections
Every Karnup 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 Karnup’s acreage properties, our builder-inspectors go beyond the main house to check sheds, patios and outbuildings for sound framing and approvals, and look at site drainage, roof runoff and the ground around tanks and wet areas.
Compliant with AS 4349.1–2007.
Termite & Pest Inspection Karnup
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.
Karnup has large bush blocks, mature trees, timber fence posts and sheds spread across acreage, which gives termites plenty of food and cover. We check the house, outbuildings and any timber in ground contact on every job.
Compliant with Australian Standard AS 4349.3–2010.
Detailed Photo Report
Your Karnup 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 building and pest inspection in Karnup cost?
Our building and pest inspection in Karnup is $499 + GST, fixed price, and it saves $99 + GST (approximately 16.6%) compared to booking the two separately, based on a 4×2 home.

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 building inspection in Karnup take?
Most inspections take 2 to 3 hours, depending on the size, age and access of the home. Older homes, bigger blocks and homes with extensions or outbuildings take longer, because we inspect all of it. Your detailed photo report arrives within 24 hours.
Do I need a termite inspection in Karnup?
Yes. Karnup properties have bushland, mature trees, timber fencing and outbuildings on large blocks, which suits termites. We inspect the house and accessible outbuildings for activity and damage. See what termite damage looks like.
Which suburbs around Karnup do you cover?
We cover all of Karnup (6176) and the suburbs around it, including Port Kennedy, Baldivis, Secret Harbour, Golden Bay, Singleton and Lakelands. We inspect right across the Peel Region & Rockingham to Mandurah Corridor and the rest of Perth.
Is a building inspection required when buying property in Western Australia?
It isn’t a legal requirement, but Consumer Protection WA recommends making your offer subject to a building inspection. Without one, you buy the home as it is. Make sure your contract includes a building inspection clause, and book the inspection within 2 to 3 business days of your offer being accepted so you have time to act on the report.
What should I look for when buying a home in Karnup?
Check every shed, patio and addition for approvals and sound framing. Look at how water drains across the block and around the house. Ask about septic, bore and tank systems. Inspect roof, gutters and timber in contact with the ground, and check whether the block is in a bushfire-prone area. Our checklist of what to check before buying covers the rest.
I’m building a new home in Karnup. Do you offer new construction inspections?
Yes. We inspect new homes at every stage, from the slab through to handover. See our guide to construction stage inspections in WA, and use our PCI checklist before you take the keys. It’s far cheaper to have the builder fix defects before you move in than after.
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.
What should I check on a rural property in Karnup with sheds and a bore?
Check the sheds and outbuildings for approvals and proper framing, and ask when they were built. Look at how the bore, tanks and septic system are set up and who last serviced them. Our inspectors check the house and outbuildings, and flag drainage, roof and structural issues.
