Pest technician?
Use this route for insects, workings or suspected pest damage.
Route the evidence, not just the symptom
Termites in bathrooms and wet areas
Swollen timber near a bathroom does not automatically mean termites. Wet areas can produce several lookalike problems, so both damage and the moisture source need consideration.
Plumber?
Use this route for active leaks, failed fixtures or unexplained water.
Builder?
Use this route to assess materials, waterproofing or repair scope; structural questions require suitable expertise.
Preserve evidence
Avoid cutting open or spraying a suspected area before it is recorded.
