“The problems that cost Perth buyers the most money aren’t the ones you can see. They’re the water leaks behind the shower wall, the moisture trail from a failed roof flashing, and the termite colony living quietly inside a wall cavity. A thermal camera catches every one of them. “
Russell McCarthy, Licensed Builder & Lead Building Inspector

Why Risk It?
What you can see isn’t what will cost you
Standard building and pest inspections are limited by what the human eye can detect. Every experienced builder will tell you the same thing: the defects that actually destroy settlements — the ones that turn into $10,000, $20,000, $40,000 rectification bills — almost always hide behind surfaces no torch can reach.
Water leaks don’t stain drywall for months. Termites don’t surface until their colony is established. Moisture behind tiled showers rots timber frames for years before anyone notices. A thermographic scan catches all of it.

FROM PERTH’S MOST TRUSTED INSPECTORs
A $300 decision on a $1M commitment
$300 on a $1M purchase. That’s 0.03%.
The typical repair bill when we find active water ingress starts at $5,000 and regularly crosses $20,000. Termite damage to structural timbers routinely costs $15,000 to $40,000 to rectify. A single undiscovered defect at settlement costs more than every inspection we’ve ever performed for you, forever.
$300 to see behind every wall before you sign. Most Perth buyers consider that the easiest decision of the entire purchase.

Frequently Asked Questions
What is a thermographic inspection?
A thermographic inspection uses infrared thermal imaging cameras to reveal problems invisible to the naked eye — water ingress behind walls, moisture in ceilings, insulation gaps, overheating electrical components, and signs of active pest infestation. Only around 1% of building inspectors in Perth use this technology — we include it as standard with this package. Learn more about thermal building inspections in Perth.
What's the difference between your standard building and pest inspection and the thermographic version?
Both meet Australian Standards and include a full written report with photos. The thermographic version goes further — we use a advanced thermal imaging cameras to detect issues behind walls, in ceilings and inside structures that no standard inspection can see. Hidden water damage, active pest activity, electrical hotspots, insulation failures. See our standard combined building and pest inspection for comparison.
Why do I need to include a thermal inspection with my building and pest inspection?
- Early Detection: Identify potential issues before they become YOUR problems if you buy the property, saving you from expensive repairs down the line.
- Enhanced Safety: Ensure the structural integrity of your building, mitigating the risk of accidents, structural failures and health hazards such as invisible mold growth that you can’t see.
- Comprehensive Report: Receive Perth’s most detailed buildind and pest inspection report with infrared images, highlighting the areas of concern and providing recommendations for necessary repairs or improvements.
How long does the inspection take, and do I need to be there?
A thermal building and pest inspection on a standard 4×2 home takes approximately 2-3 hours on site. You don’t need to be present — we coordinate access directly with the real estate agent or vendor. If you want to attend, you’re welcome. Either way, you get a follow-up phone consultation after the report is delivered.
How much is a building and pest inspection with thermographic imaging in Perth?
Based on a standard 4×2 home, a Comprehensive Building & Pest Inspection with Thermographic Inspection is $799 for new customers (normally $999) — limited spots available. See all our pricing and service options.
Why combine the thermal, pest and building inspection?
Two reasons:
- Early detection. Catch water leaks, rising damp, termite activity and structural issues before they become your problem after settlement.
- Australian Standards compliance. The report is compliant with AS 4349.1-2007 (pre-purchase) and AS 4349.3-2010 (timber pest), so it’s recognised by solicitors, real estate agents and courts.
What's in the report?
A comprehensive photo report with thermal imaging of the entire property, broken into easy-to-read sections: safety issues first, then major defects, minor defects, maintenance items, and a comparative summary. Every finding is documented in plain English alongside the relevant image. After the report is delivered, our independent building inspector in Perth calls you to walk through the findings so you know exactly where you stand. See recent defect examples from real Perth inspections.
If the report finds defects, can I withdraw from the contract?
Yes — potentially. Our reports comply with Australian Standards, meaning solicitors and real estate agents recognise them as valid evidence. If your contract contains a building and pest inspection condition (most WA contracts do), the report gives you and your solicitor the documented proof to either rescind the contract or negotiate. That’s your decision and your solicitor’s — our job is to give you the evidence.
Can I use the report to negotiate a price reduction?
Yes — and many of our clients do exactly this instead of asking for repairs. The thermal imaging in particular pinpoints the location and extent of issues (water damage behind walls, for example), which gives you concrete numbers to put to the vendor. Read how to negotiate after a building and pest inspection.
What suburbs do you cover?
All of Perth metro and surrounding regions — north to Two Rocks, south to Mandurah, east to the hills, plus regional WA. We’re local builders and inspectors, so we know the specific building stock and common defects in each suburb. See all the areas we service.
What makes WA Building Inspections different from other Perth inspectors?
Four things:
- We’re registered builders (BP104751), not just inspectors. We’ve built the homes we’re now inspecting, so we know exactly where builders cut corners.
- RAC-authorised. We’re the only RAC-authorised building and pest inspection company in Perth.
- Recognised by HIA and Master Builders. Master Building Inspector status and HIA membership.
- Thermal imaging included — most Perth inspectors don’t invest in these high cost technologies.

What thermal cameras do you use?
We use professional-grade thermal imaging cameras from both Thermal-Master and FLIR, including higher-resolution models than most Perth inspectors carry. Higher resolution means we can detect smaller temperature differences — which is what reveals subtle water ingress, slow leaks, and early-stage pest activity that lower-resolution cameras miss entirely.
These aren’t consumer devices. They require certified thermographer training to operate correctly and interpret the data. Our inspectors are certified infrared thermographers, not just camera operators.
What should I ask the seller to fix after the inspection?
Prioritise safety issues and items that could cause significant damage if left — faulty electrical, active leaks, roof defects, structural issues. Cosmetic items (peeling paint, dated fixtures) are lower priority. Many clients choose to negotiate a price reduction using the report as evidence rather than asking the seller to carry out repairs they may rush. The thermal imaging is especially powerful here because it shows exactly what the damage is and where. Read more on post-inspection negotiation.
