A termite inspection in Perth is a systematic, on-site assessment of all accessible timber and structural elements of a property, conducted by qualified inspectors to detect active termite activity, past damage, and conditions that could attract termites. Most Perth buyers do not realise that a standard pre-purchase building inspection does not cover termites at all. Missing this single step can cost tens of thousands of dollars in structural repairs that insurance will not touch.
At Bestwest Building, a termite inspection is delivered by our extensive team of highly experienced registered builders and accredited timber pest specialists. The findings are reported in a same-day digital report with full-resolution photographs, most commonly as part of a combined building and pest inspection for pre-purchase buyers.

Why Perth and South West WA Are High Termite Risk
Perth and the surrounding metro region sit within an area classified as high to very high risk for termites under the National Construction Code. The combination of warm temperatures, sandy soils that allow termites to forage easily, and the prevalence of timber-framed homes makes the city one of the higher-risk capitals in Australia. South West WA, including suburbs like Mandurah, Bunbury, and Margaret River, carries similar risk levels.
Three species of termites are commonly encountered in Perth homes:
- Coptotermes: the most economically damaging species in WA, often found in subfloor and wall cavities
- Heterotermes: less destructive but extremely common in older properties
- Schedorhinotermes: aggressive coastal species, prevalent in newer coastal developments
A termite inspection identifies active colonies, evidence of past damage, and conducive conditions like moisture intrusion, timber-to-ground contact, and inadequate subfloor ventilation that increase the likelihood of attack.
What Inspectors Actually Check on the Day
A thorough termite inspection in Perth takes between 60 and 90 minutes for a standard residential property. The inspector covers every accessible area where termite activity could occur, using a combination of visual assessment and specialist tools.
The Tools Used
- Termite sounding tool: identifies hollow timber, which is a strong signal of internal damage
- Torch and inspection mirror: for confined spaces in subfloor and roof void
- Direct visual assessment: trained inspectors identify signs that the average eye misses
The Areas Inspected
Inspectors work through the property systematically, paying particular attention to high-risk zones:
- The subfloor and crawl space areas (where accessible): this is where the highest concentration of activity is typically found
- The roof void: timber framing, rafters, and any stored timber
- All internal rooms: walls, skirting boards, architraves, door frames, and timber flooring
- External walls and eaves
- Garden areas: timber retaining walls, fences, garden beds adjacent to the home
- Detached structures: sheds, pergolas, carports, and decks
The Signs Inspectors Look For
Three common signs of termite activity will catch an inspector’s attention immediately:
- Mud tubes: pencil-thin earth tunnels running up walls, foundations, or piers, used by termites to travel between their nest and food source
- Hollow-sounding timber: when tapped, timber that has been internally eaten by termites produces a distinctive papery or hollow sound
- Frass: small piles of pellet-like droppings near doors, windows, or skirting boards, indicating drywood termite activity
Termite Damage: What Goes Wrong When It Is Missed
Termite damage in Perth is rarely covered by home insurance. Most policies specifically exclude termite damage on the basis that it is preventable through regular inspections. The cost of remediation depends on the extent and location of activity.
Common repair scenarios include replacement of damaged wall framing, structural timber repair after termite damage, replacement of damaged flooring, and repairs to door frames and skirting. A severe untreated infestation can require partial or full structural repair costing $2,500 to $30,000 or more.
The financial logic is straightforward: a termite inspection costs a fraction of the repair cost it prevents. For pre-purchase buyers, a pre-purchase building inspection combined with a timber pest inspection in a single visit is the most comprehensive option, and is what we strongly recommend for any established property in WA.
How Often Should You Get a Termite Inspection in WA?
The Australian Standard AS4349.3 recommends a minimum of one termite inspection every 12 months for properties in high-risk areas, which includes Perth and South West WA. Some property types and conditions justify a 6-month inspection cycle:
- Properties with previous termite activity
- Homes with high moisture levels in subfloor or wet areas
- Properties with extensive timber landscaping near the home
- Older homes built before modern chemical barrier requirements (pre-1995)
- Coastal homes with high humidity exposure
Annual inspections become especially important if your property has been treated with termite barriers in the past, as most barrier treatments have a 5 to 8 year warranty that may require annual inspection compliance to remain valid. A timber pest inspection verifies the barrier is still effective and detects any breaches.
Termite Inspection vs Building Inspection: What Is the Difference?
A standard building inspection in Perth assesses the structural condition and overall quality of a property under AS4349.1. It does not include termite or timber pest assessment.
A termite inspection, also called a timber pest inspection, is conducted under AS4349.3 and focuses specifically on:
- Active termite presence
- Evidence of past damage
- Wood-decay fungi (rot)
- Borers and other timber-attacking insects
- Conducive conditions that attract pests
For pre-purchase buyers, a pre-purchase building and pest inspection delivered in a single visit is the most efficient and comprehensive option. It typically takes 1.5 to 3 hours and produces two reports: the building inspection report and the timber pest report.

Frequently Asked Questions About Termite Inspections in Perth
What does a termite inspection in Perth include?
A termite inspection in Perth covers all accessible timber and structural elements of a property including the subfloor and crawl space areas, roof void, internal and external walls, eaves, fences, retaining walls, and detached timber structures. Inspectors use termite sounding tools and direct visual assessment to identify active termite activity, past damage, and conditions that attract termites. The inspection is reported under AS4349.3, the Australian Standard for timber pest inspections.
How often should I get a termite inspection in WA?
The Australian Standard AS4349.3 recommends a minimum of one termite inspection every 12 months for properties in Perth and South West WA due to the region’s high-risk classification. More frequent inspections, every 6 months, are recommended for properties with prior termite activity, high moisture issues, or treated barrier protection that requires compliance monitoring to maintain its warranty.
What is the difference between a building inspection and a termite inspection?
A building inspection assesses the structural condition of a property under AS4349.1 but does not check for termites. A termite inspection, conducted under AS4349.3, specifically checks for active termite presence, past damage, and timber pest conditions. For pre-purchase buyers, a combined building and pest inspection delivered in a single visit covers both standards and is the most comprehensive option for any established property in WA.
