Fence posts, pergolas and termites in Castle Hill gardens

Timber touching soil is the quiet invitation in many established gardens.

Castle Hill 2154 · 26 February 2026

In short: On Castle Hill building and pest inspections, timber in ground contact appears far more often than live termites. It is the condition that makes a future problem likely.

What we keep seeing

Timber fences sitting directly in soil, posts embedded in the ground under pergolas and decks, and support posts buried at the edge of new courtyards. Each is a bridge between soil and timber.

Why termites use it

Subterranean termites live in the soil and travel through it. Timber in contact with the ground lets them feed without being exposed, and the damp at ground level helps them.

A new home is not exempt

We have recorded posts buried in soil at handover on new Castle Hill homes. The termite management system protects the house, not a post the landscaper set in the ground beside it.

Simple fixes

Steel stirrups or brackets that lift posts clear of the soil, treated timber rated for ground contact, and keeping mulch and soil away from fences where they meet the house.

How the report deals with it

It names the location, photographs it and explains why it matters, so you can fix it or ask a pest controller to factor it into a management plan.

FAQ

Questions Castle Hill owners ask about this

Is treated pine safe in the ground?

Only if it is rated for in-ground use, and even then it can let termites travel past it unseen.

Will a fence touching the house let termites in?

It can, if it bridges the termite barrier or hides an entry point.

Do you inspect the whole garden?

We inspect timber structures within the property boundary that are accessible on the day.

What if termites are found?

We report the location and extent and recommend a licensed pest controller.
