The purpose of an inspection for wood destroying organisms (WDOs) in a building is to assess evidence of the insects and the severity of the damage caused, and to recommend the appropriate remedial and protective measures required.
To fulfil their responsibilities, inspectors must be familiar with the principles of construction, including the type and style of the building relevant to timber pest activity and damage. They must also be knowledgeable about the ecology, behaviour and identification of timber pests and be familiar with the damage the pests cause and the procedures required for their eradication and prevention.
Items to be inspected
All accessible timber in service within the property boundaries must be inspected, such as:
- Structural timber – subfloor, floor walls, stairs, ceilings, roofing and eaves.
- Joinery and decorative timbers - doors and door frames, windows and window frames, skirtings and joinery.
- Auxiliary structures - false floors, built-in cupboards and built-in furniture.
- Attachments and outbuildings - garages, carports, pergolas, patios, verandas, sheds and posts and fencing.
Timber items on the property that are excluded from the standard WDO inspection include furniture, furnishings, stored items, concealed timbers, and inaccessible timbers. However, it is important to note these on the inspection report.
Inspection of the property consists of a visual examination of all accessible areas of the property for the following:
- Evidence of the presence of wood destroying organisms. Common names must be identified, as well as genus and, where relevant, the species of the timber pests, location of activity or damage, and a general description of the severity of the damage.
- Evidence of inactive wood destroying organisms.
- Evidence of previous treatment for wood destroying organisms.
- Damage caused by wood destroying organisms.
