INSPECTIONS BY REGISTERED BUILDERS
South East Perth & Canning Region’s #1 Rated Building and Pest Inspection
The South East and Canning corridor is three property markets stacked together — established post-war stock through Cannington, Thornlie, Maddington and Gosnells; the new-build growth corridor pushing south through Harrisdale, Piara Waters, Byford and Mundijong; and foothills acreage across Bedfordale, Roleystone and Oakford. Each pocket trips up generic inspectors differently.
On older homes through Cannington, Thornlie, Wilson, Maddington and Kelmscott we look closely at asbestos materials, original switchboards, polybutylene plumbing, and waterproofing failures from past bathroom retrofits — risks that come with the territory in suburbs that regularly top Perth’s cheapest suburbs lists. See what we found on a recent Cannington roof inspection.
In the new-build corridor — Harrisdale, Piara Waters, Forrestdale, Byford, Mundijong — reactive clay soils make pre-slab pour inspections critical, and the region is heavily affected by IPLEX polybutylene pipe failures and BGC IPLEX disasters. See a new-build nightmare we exposed in Cannington and a major roof undulation we uncovered in Beckenham.
Out toward the foothills it’s a different game entirely: BAL compliance, septic and ATU systems, bore infrastructure, slope retaining walls, and outbuildings most inspectors skip.
Our inspectors are licensed registered builders (BP104751). Real Builders. Better Inspections. 30,000+ Perth home buyers have trusted us.
What’s Included in Your South East Perth & Canning Building & Pest Inspection
Comprehensive Pre Purchase Building Inspections
Because our inspectors are licensed registered builders, we inspect every accessible area — but South East and Canning properties need a sharper eye than most metro inspections deliver, because the housing stock spans seven decades of construction standards.
On established homes through Cannington, Thornlie, Gosnells, Maddington and Kelmscott we pay particular attention to asbestos-era materials in eaves, fences, shed walls and bathroom linings, original electrical switchboards, polybutylene plumbing, hidden waterproofing failures from past bathroom retrofits, and unpermitted DIY structural alterations. We also check for terracotta roof issues every Perth homebuyer keeps missing — a problem we see right across the inner south-east, where original 1960s and 70s tiled roofs are quietly failing.
On new-build estates through Harrisdale, Piara Waters, Southern River, Forrestdale, Byford and Mundijong we focus on handover-specific defects our practical completion inspections routinely uncover — slab and footing movement on reactive clay soils, weep hole compliance issues, waterproofing and wet-area failures meeting AS 3740 standards, frame and truss defects, plumbing compliance, and builder cost-cutting hidden behind finishing work.
Every defect is reported in plain English with photographs. See a sample report to understand exactly what you’ll receive.
Compliant with Australian Standard AS 4349.1–2007
Termite & Pest Inspection South East Perth & Canning
The South East corridor sits in one of Perth’s higher termite pressure zones — driven by proximity to the Canning River corridor, the Wungong Brook system through Armadale, the Darling Scarp bushland reserves edging Bedfordale, Roleystone and Karragullen, and the mature established gardens through Thornlie, Gosnells and Kelmscott. We regularly find active infestations and significant historic termite damage across the region — and we frequently find termite activity on newer Harrisdale, Piara Waters and Byford homes too, because yes, you absolutely can get termites in a new house when termite barriers are failing or were never installed correctly.
We inspect all accessible timber structures and pay particular attention to earth-to-timber contact at veranda posts, deck bearers, retaining walls, timber outbuildings, fencing and garden bed levels built up against house foundations. We also assess termite management systems on newer builds and flag where chemical barriers or termite mesh are failing, missing or non-compliant.
Compliant with Australian Standard AS 4349.3–2010.

Our inspectors inspect more than your average inspector. How? We are qualified builders, so we go where the others won’t and we detect what the others cant.
You can view exactly what we inspect for a pest inspection perth, termite inspection perth or any inspection we offer, including our fixed building inspections perth costs from our Pricing page.

Which South East Perth and Canning suburbs do you cover?
We cover every suburb across the South East Perth and Canning corridor — including Cannington, Beckenham, Thornlie, Canning Vale, Wattle Grove, Wilson, Lynwood, Riverton, Huntingdale, Gosnells, Maddington, Kelmscott, Armadale, Champion Lakes, Brookdale, Forrestdale, Harrisdale, Piara Waters, Southern River, Byford, Mundijong, Serpentine, Oakford, Karragullen, Roleystone and Bedfordale. Fixed pricing applies with no travel surcharges. For neighbouring regions, see our Rockingham to Mandurah and Fremantle & South-West Perth pages.
Do older homes in Cannington, Thornlie or Gosnells need a different inspection approach?
Yes — and this is exactly where most metro inspectors miss the worst defects. Established South East housing stock spans seven decades, with significant numbers of homes still containing asbestos materials in eaves, fences, floor tiles and shed walls, original electrical switchboards that no longer meet current safety standards, and polybutylene plumbing well past its design life. We regularly find unpermitted DIY structural alterations, hidden waterproofing failures from incomplete bathroom retrofits, and roof timbers compromised by past termite activity. We documented exactly this kind of hidden roof defect on a recent Cannington pre-purchase inspection — the kind of thing only a registered-builder inspector is trained to spot.
What should I look for when buying a new build in Harrisdale, Piara Waters, Byford or Mundijong?
The Harrisdale–Piara Waters–Byford–Mundijong growth corridor has one of the highest new-build defect rates we encounter anywhere in Perth. Reactive clay soils through the corridor create ongoing slab heave and footing movement risk — which is why we strongly recommend pre-slab pour inspections and proper slab inspections with flexible bond breakers on every new build in the corridor. Common construction issues we see across the region include: waterproofing failures in bathrooms and laundries, frame and truss defects hidden behind plasterboard, weep hole non-compliance, plumbing issues including IPLEX polybutylene installations failing across the region, incomplete handover works, and cost-cutting hidden behind finishing work. We strongly recommend a practical completion inspection before you sign off handover. See examples of dodgy builder work we’ve uncovered and a recent Cannington new-build nightmare we exposed.
I'm looking at the cheaper South East suburbs — Armadale, Gosnells, Maddington — what should I be aware of?
Suburbs like Armadale, Gosnells, Maddington and Kelmscott regularly appear on Perth’s cheapest suburbs lists — and there’s real value to be had for first home buyers and investors. But the reason these suburbs are affordable is that the housing stock is older, has often been through multiple ad-hoc renovation cycles, and frequently carries deferred maintenance the listing photos won’t show. The risks we most commonly find: asbestos in eaves and outbuildings, unpermitted alterations (especially garage conversions and patio enclosures), original galvanised plumbing that’s reached the end of its life, original switchboards, sagging or undulating roofs, and termite activity in mature gardens. A thorough pre-purchase inspection is the difference between a great bargain and an expensive mistake.
Do you inspect acreage and rural-residential properties in the foothills?
Yes — acreage and rural-residential inspections through Bedfordale, Roleystone, Karragullen, Oakford, Mundijong and Serpentine are one of our specialties. Foothills buyers face risks standard suburban inspections never address: septic and ATU wastewater system condition and compliance, bore and water tank condition, outbuilding and shed compliance, fencing condition, soil and drainage assessment on slope, retained earth structures, and bushfire attack level (BAL) compliance for the dwelling. We assess all of this so you understand the full picture before settling.
Im building a new house. Do you offer new building construction inspections?
Yes, we specialise in new building construction inspections, providing comprehensive services for future homeowners across Perth, including Midland and its surrounding suburbs.
Here are the New Construction Inspections we offer:
1) Practical Completion Inspection Perth.
2) Building Construction (Stage) Inspection Perth.
3) Waterproofing Inspection Perth.
Our extensive coverage includes areas from Midland itself to Eastern Suburbs, Perth, Midvale, Bellevue, Hazelmere, and further to areas like Ellenbrook and Aveley.
Understanding the local nuances of each suburb, from the bustling community in Bassendean to the scenic views in Guildford and the tranquil lifestyle in Parkerville, is crucial for our work. Our services are tailored to meet the unique environmental, regulatory & community standards across these diverse locations, ensuring your new home is built to, and exceeds the standards and designs.
Whether your new construction is near Midland, close to the natural beauty of Greenmount National Park, or within the vibrant surroundings near Caversham Wildlife Park and Whiteman Park, our team is equipped with the local knowledge to ensure a smooth and compliant building process. Our inspections are designed to navigate the specific challenges and advantages of building in Perth’s diverse landscape, from the heritage-rich areas near The Railway Museum to the serene riverside locales like Woodbridge Riverside Park.
Can you negotiate price after building and pest inspection?
Yes — and our reports are designed to give you the strongest possible position. We document the property’s condition in detail with photographs and plain-English explanations of every defect against the relevant Australian Standard. Whether it’s an established home in Thornlie with hidden waterproofing failures, a foothills block in Roleystone with septic compliance issues, or a new build in Harrisdale with slab heave, our findings give you a clear basis to renegotiate price or request remediation works before settlement. See our full guide on how to negotiate after a building and pest inspection.
Do I need a termite inspection in South East Perth?
Yes — strongly recommended. The South East Perth and Canning corridor sits in one of Perth’s higher termite pressure zones — driven by the Canning River, the Wungong Brook system through Armadale, the Darling Scarp bushland reserves through Bedfordale and Roleystone, and decades of timber-framed construction across the older suburbs. We regularly find evidence of termites or termite-conducive conditions across the region, and as we’ve documented, you absolutely can get termites in a new house too — including newer Harrisdale, Piara Waters and Byford homes where termite barriers are failing or non-compliant. See what termite damage actually looks like and why a termite inspection is critical when buying.
What is BAL compliance and does it apply in the South East?
Bushfire Attack Level (BAL) compliance is the building standard that applies to homes built or renovated in bushfire-prone areas — including significant portions of Bedfordale, Roleystone, Karragullen, the foothills fringes of Armadale and Kelmscott, and parts of Byford and Mundijong backing onto bushland reserves. The BAL rating dictates the construction standard required (BAL-12.5 through BAL-FZ) and affects window glazing, eaves, vents, decks, shutters, roof construction and clearance to vegetation. We assess BAL-relevant construction features so you understand whether the property complies — non-compliance can be a major insurance and renovation issue.
