These examples of a large exposed deck and house without appropriate termite barriers. Also not enough clearances between the soil and timber.

A substantial amount of money would be required to rectify these identified defects.

Common termite entry points in buildings

Timber that is within the soil, creating direct entry for termites.

These bearers have insufficient clearances between the soil of the sub-floor area.

The bearers must have at least 400 mm clearance between them and the soil, to comply with Building code requirements. 

Stumps that are supporting this deck have no ant-capping termite barriers.

Termite entry points in homes

This bearer is actually in direct contact with the ground, an open invitation for termite entry!

Worth knowing:

  • All timber must have clearances between soil.
  • Bearers must have at least 400mm between underside and soil to comply with building code requirements.
  • Sub-floor areas must have required access to allow detection of termites.
  • Cross flow vetilation required to sub-floor areas.

The next building inspector did not identify any of these major problems. Not being informed would cost a buyer dearly, immediately or when selling!
