Termite protection · NSW
Most Sydney homes were built without a termite barrier, or their original protection has since expired. Grove’s retrofit installation brings protection to existing homes, using a method matched to how your home is built and installed to Australian Standards (AS 3660.2).
How it works
The installation method depends on how your home is built. Both approaches establish a continuous treated barrier around the structure.
For homes on stumps, piers or with a crawl space, soil around internal piers and the external perimeter is trenched and treated with Termidor (fipronil) at the correct dosage. Termidor is a non-repellent treatment, so termites move through it without detecting it and carry the active ingredient back to the colony through contact and grooming.
For concrete slab homes, Termcoat is applied into wall cavities below the damp proof course. This CodeMark certified treatment creates a termite-resistant zone on masonry surfaces, addressing the path termites would otherwise take from soil into the structure. Where perimeter soil is accessible, soil treatment supplements the Termcoat application.
Every retrofit barrier installation begins with a thorough termite inspection. Any active termites are addressed before barrier work begins, and you receive a detailed written report covering findings, risk conditions and the proposed barrier scope.
After installation you receive a Certificate of Installation covering barrier type, chemical used, application rates, treated areas and any limitations. A durable notice is fixed to the building in line with Australian Standards, supporting future property sales and insurance records.
Is it right for you?
Your home was built before current codes required termite protection, or the original barrier was never installed. A retrofit barrier brings protection to the property.
Chemical soil treatments and treated physical barriers degrade over time. If more than five to eight years have passed since your last treatment, your home may no longer be effectively protected.
New concrete joins, slab penetrations or added structures create fresh entry points that need to be brought into a continuous barrier.
A current, documented termite barrier adds genuine value to a property transaction. Buyers and conveyancers increasingly ask for evidence of termite protection.
Pricing & getting started
Pricing depends on construction type, perimeter length, accessibility and the treatment scope required. Most standard Sydney homes fall between $2,000 and $5,000 for a full installation. Contact Grove for a detailed phone quote, or send through your details for a response within one business day.

Yes. It’s a common assumption that barriers can only go in during construction, but a retrofit barrier can be applied to any existing home, using a method suited to how it’s built.
For subfloor homes, soil around the piers and perimeter is trenched and treated with Termidor. For slab-on-ground homes, Termcoat is applied into wall cavities below the damp proof course and supplemented with soil treatment where the perimeter is accessible. Both methods create a continuous treated zone around the structure.
Termcoat is a CodeMark certified termite treatment applied to masonry surfaces and wall cavities below the damp proof course. It creates a termite-resistant zone on surfaces where termites would otherwise travel undetected from soil into the structure, and is designed for slab-on-ground homes built to AS 2870.
A chemical termite barrier typically provides effective protection for five to eight years, depending on the product used, soil conditions and environmental factors. Annual termite inspections are recommended to monitor how the barrier is performing over time.
Any active termites are addressed before barrier installation begins, which is required under Australian Standards. Non-repellent treatments are applied directly to the affected area, and barrier installation proceeds once activity has settled.
Physical barriers, such as stainless steel mesh or treated polymer sheeting, are installed during construction to block termite entry mechanically. Chemical barriers create a treated zone in soil or on masonry that controls termites on contact and through colony transfer. For existing homes without a physical barrier, a chemical retrofit barrier is the practical option.
Yes. Australian Standards recommend annual termite inspections for all homes, including those with a current barrier. Inspections check barrier condition, note any site changes, and pick up early signs of termite activity. PerimeterCare Complete and PerimeterCare both include annual inspections as standard.
Trenching involves digging a narrow channel along the perimeter, which is backfilled after treatment. Where a concrete path or driveway crosses the perimeter, the soil beneath is treated via drilling, and the drill points are then sealed. The Termcoat method for slab-on-ground homes involves no trenching or drilling. We keep the property tidy and explain the process before work begins.
