What a Pre-Purchase Pest Inspection Assesses
A pre-purchase pest inspection to AS 4349.3 is a timber pest assessment, not a general pest treatment inspection. It identifies conditions relevant to a property purchase decision, not existing pest pressures from cockroaches or ants.
Termite activity and damage
The primary focus of any pre-purchase inspection in Brisbane. The inspector checks all accessible timber in the building for live termite workings, termite damage, and evidence of previous termite activity. This includes wall framing, roof timbers, subfloor bearers, external timber, and any garden structures within the inspection boundary. Brisbane is in a high termite risk zone (Zone 1 under AS 3660.1), which makes this assessment essential for any pre-purchase property assessment.
Wood-boring beetles (borers)
Exit holes in timber from wood-boring beetles are examined throughout the property. Fresh frass (powdery boring dust) around exit holes confirms active infestation. The report distinguishes between active borer damage requiring treatment and historical exit holes from a completed lifecycle. Borer species identification is noted where possible, as treatment requirements differ between softwood-attacking species (Queensland pine beetle) and hardwood-attacking species (lyctus, anobiid).
Wood decay fungi (rot)
Timber affected by wood decay fungi is assessed for extent and structural significance. Decay is caused by moisture and is not from an insect pest, but it is within the scope of an AS 4349.3 timber pest inspection. Subfloor bearers, external decking, window frames, and any timber in contact with soil or subject to water retention are the most common decay locations in Brisbane homes.
Conducive conditions assessment
Conditions that increase the risk of future termite attack are identified: inadequate subfloor ventilation, timber-to-soil contact, moisture accumulation near the building perimeter, dense garden mulch against the walls, and the absence of or gaps in an existing termite barrier. These are documented in the report as risk factors even when no active pest activity is found, giving the buyer a picture of the property's ongoing termite risk profile.
Equipment Used in a Pre-Purchase Pest Inspection
A pre-purchase inspection uses more than visual assessment. These instruments are the standard toolkit for an AS 4349.3 inspection in Brisbane.
Thermal imaging camera
Detects temperature differentials inside wall cavities. Active termite workings and moisture ingress show as temperature anomalies requiring follow-up investigation.
Moisture meter
Measures moisture content in wall linings, framing, and timber surfaces. Elevated moisture readings indicate conditions conducive to termite activity or timber decay.
Termite detection device
Electronic listening devices (Termatrac or equivalent) detect termite movement sounds and microwave reflections inside wall cavities without drilling or surface damage.
Sounding probe
Manual tapping of timber surfaces to detect hollow sections. The distinctive sound of termite-damaged hollow timber is the most reliable detection method in accessible areas.
Inspection torch and mirror
High-intensity lighting for subfloor, roof void, and internal cavity inspection. Telescopic mirror for low-clearance subfloor and tight roof void sections.
Digital reporting system
Findings documented on-site in the inspection software. Report generated from site data and delivered to the buyer within 24 hours of inspection completion.
What a Pre-Purchase Timber Pest Report Documents
The report is a legal document accepted by banks, lenders, conveyancers, and courts. It must contain specific sections under AS 4349.3 to be valid for property purchase purposes.
Property details and inspection scope
Address, date, inspector name and licence number, access conditions, weather on the day, and areas inspected vs areas not accessed with reasons.
Termite findings
Location, species (where identifiable), apparent extent, and condition of any termite activity found. Photographed and mapped to a property diagram. Class rating of risk.
Wood-boring beetle findings
Location, species class, active vs historical assessment based on frass presence. Structural significance rating.
Wood decay findings
Location, extent, apparent cause (moisture source), and structural significance assessment. Includes external decking, subfloor, and window frame rot.
Conducive conditions
Moisture problems, inadequate ventilation, timber-to-soil contact, mulch against walls, barrier gaps. Rated by risk level.
Recommendations
Treatment recommendations for any findings, with urgency rating. Ongoing prevention recommendations. For barrier installation, a separate treatment quote is provided on request.
Should You Book a Combined Building and Pest Inspection?
Most Brisbane property buyers book both a building inspection and a pest inspection before committing to a purchase. Whether to combine them or book separately depends on whether a single dual-qualified inspector is available for the property.
Pre-Purchase Pest Inspection Cost Brisbane
All inspections include thermal imaging camera assessment, moisture meter readings, sounding probe and electronic detection where warranted, and an AS 4349.3-compliant written report within 24 hours.
| Property type | Price | Notes |
|---|---|---|
| Standard house (3-4 bed, slab-on-ground) | $280-$320 | Full inspection including roof void. Report within 24 hours. |
| Standard house with subfloor void | $300-$360 | Subfloor inspection adds time. Inspection time approximately 90 minutes. |
| Large house (4+ bed, multiple outbuildings) | $340-$420 | Extended inspection area. Complex roof void or multiple structures. |
| Apartment or unit | $220-$280 | Accessible areas only. No subfloor. Roof void typically inaccessible. |
| Combined building and pest inspection | $480-$680 | Single dual-qualified inspector. One report. Better value than two separate inspections. |
