South West Sydney · AS 3660.1
Barriers fitted before the pour on Bossley Park rebuilds and outdoor extensions, on blocks running down towards Orphan School Creek and the local bush reserves.
Quick answer
Yes, a new home, extension or rebuild in Bossley Park needs a termite management system, since the City of Fairfield area is termite-prone under the NCC. Collars and under-slab work go in before the pour, to AS 3660.1 standard, and the durable notice with installation certificate are supplied to your certifier once occupation is applied for.
Termite barriers in Bossley Park
Bossley Park was rural land until the 1970s, when it was developed for housing, so most homes date from that decade onwards and the suburb is now fully built out. Building work here is mostly knockdown rebuilds, extensions and outdoor additions on those established blocks rather than new subdivisions. The City of Fairfield handles certification here too, and any new slab, whether it is a full rebuild or a smaller extension footing, still calls for a compliant system, fitted before the pour and signed off well ahead of the final Occupation Certificate.
Remnant eucalypt woodland and Orphan School Creek, which winds along the southern edge through Comanche Park, keep parts of Bossley Park close to bush conditions even though the suburb is fully residential. Bush edges like this can bring termites, spiders and possums closer to homes, and creek corridors keep the soil damp for longer after rain. Many Bossley Park houses have also had pergolas, decks and outdoor entertaining areas added over the years, and those timber extensions are worth checking closely for termite activity before a new slab or footing goes down nearby.

Local conditions
Three things shape termite risk on a Bossley Park build, tied to the bush and creek setting.
The creek and nearby bush reserves such as Nazareth Reserve keep soil damp and full of leaf litter close to some streets, conditions subterranean termites use to forage into gardens, so blocks near the creek get fuller perimeter attention.
Pergolas, decks and outdoor entertaining areas added to Bossley Park homes since the 1970s are common termite targets, and a new extension footing going in near existing timber structures needs the same careful barrier as a full rebuild.
Most Bossley Park homes sit on blocks that have carried gardens and mature trees for around fifty years, and old buried timber in that soil can sustain a colony long before a rebuild's new slab ever goes down, so we check the ground before quoting.
What we install here
Bossley Park work is mostly knockdown rebuilds, extensions and outdoor entertaining additions on established blocks. Waffle pod and raft slabs are standard for rebuilds, every pipe penetration and conduit is collared and sealed before the pour, and extension footings get the same care where they sit close to existing timber decks or pergolas. One written quote from the plans covers every stage, timed to your builder's program from start to finish.
Local knowledge
Blocks nearer Orphan School Creek and Comanche Park sit closest to damp, bush-fed ground, so the perimeter on that side gets extra attention. Around Marconi Stadium and Bossley Park Shopping Centre, sites are more built up, but the same established 1970s garden pattern applies across most of the suburb, so buried timber in the soil is worth checking for on almost every rebuild.
The City of Fairfield certifies Bossley Park builds. A notice recording the termite management system installed, housed in the meter box, and an installation certificate showing the products used, areas protected and licensed installer, are both required before the Occupation Certificate. We supply both, plus product data sheets and maintenance advice, ready whenever your other Fairfield approvals fall into place.

Systems we install
Every photo below is from one of our own Sydney jobs. We look at your slab design, site and budget, then recommend a system or a combination.
01A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
A termite barrier isn't a single visit. Each part goes in when the site is ready for it, and we fit around your plumber, concreter and bricklayer.
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.
Compare systems
Both can meet AS 3660.1. The best choice depends on your slab type, what surrounds the house and how much ongoing upkeep the owner wants.
Physical protection
Entry-point protection
Soil protection
Top-up protection
Most of the Sydney builds we work on use a combination: physical collars on every penetration plus a physical or chemical perimeter.
For builders & developers
Builders, developers and owner-builders get a fixed quote from plans, a technician who turns up when the site is ready, and paperwork that never holds up sign-off.
Consistent pricing across lots, one point of contact and a full document set for every dwelling.
Missing durable notices and unclear install records are a common reason Occupation Certificates get held up. We hand everything over together so your certifier has it all in one go.
Paperwork
A complete document set for the builder, the certifier and every future owner of the property.
A permanent notice in the meter box showing the system, install date, installer, any chemical's life expectancy and inspection advice.

Bossley Park questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Blocks close to the creek and nearby woodland sit nearest established termite activity, so we usually recommend a fuller physical perimeter rather than a minimal one on that boundary. The standard required is the same as anywhere else in Bossley Park, but the detailing gets more attention on that side.
Yes, pergolas, decks and outdoor rooms are common in Bossley Park and are also common termite targets. If you are adding a footing or slab near existing timber structures, we check those structures as part of quoting the new barrier, since termites can already be active in them without any visible sign.
We look for old stumps, buried garden timber and fence lines left over from decades of family use, since that material can already be feeding a colony before the new slab goes down. It does not change the compliant system required, but it does shape how the soil treatment is carried out.
In most cases, yes. The National Construction Code requires a termite management system for new houses and outbuildings in termite-prone areas where the primary building elements can be damaged by termites. Sydney is termite-prone, so the system is installed to AS 3660.1 and your certifier asks for the installation certificate and durable notice before the Occupation Certificate is issued.
It depends on slab area, perimeter length, the number of pipe penetrations, the system chosen, site complexity and how many visits the build needs. Send us the plans and we return one fixed written quote covering every stage. Quoting is free.
