About granny flat termite barrier
Granny flats and secondary dwellings need the same termite protection as the main house — and because they're often added later, the right barrier is essential to keep your warranty and your investment safe.
We install and certify barriers sized for granny flats, whether they're slab-on-ground or built over a subfloor, with minimal disruption to the build.
Why protect the build
New builds attract termites
Fresh timber, disturbed soil and building moisture make a site prime termite territory from day one.
Rarely insured
Termite damage is almost never covered by home insurance — the barrier is the protection.
Required for approval
A compliant termite management system is a building-code requirement for new work in NSW.
Cheapest at build stage
Installing protection during construction costs a fraction of retrofitting it later.
Why choose this barrier

Barrier design and pricing scaled to a secondary dwelling, not a full home.
Slab or subfloor
Solutions for both slab-on-ground and subfloor construction.

Your questions, answered
Does a granny flat actually need a termite barrier?
Yes — secondary dwellings are subject to the same building-code termite-management requirements as a new home, and the same termite risk.
Slab or subfloor — which do I need?
It depends on the construction type. We assess the build and install the right system, whether it's a slab-edge/penetration treatment or a subfloor barrier.
How quickly can you do it?
Granny-flat barriers are fast — we slot into your program and turn them around quickly so they never hold up the build.
