South West Sydney · AS 3660.1
Most West Hoxton homes are now 20 to 25 years old, the age where original termite protection starts failing, so we check what's already there before pricing any rebuild.
Quick answer
Under the NCC, Liverpool City is classed as termite-prone, so any new home or knockdown rebuild in West Hoxton needs a compliant termite management system before it can be occupied. Built to AS 3660.1, that means collars on every penetration and a completed perimeter before the concrete pour, with a certificate prepared for your certifier once the work is done.
Termite barriers in West Hoxton
West Hoxton is a Liverpool City suburb in postcode 2171, about 36 km west of the Sydney CBD. The land stayed largely rural until the late 1990s, when it was developed as a residential suburb and grew very quickly over the following years. Lake Francis is a local landmark, and schools including Hoxton Park Public School and Clancy Catholic College serve the area. Most of our work here now is knockdown rebuilds and renovations on that late-1990s and early-2000s housing stock, alongside new homes on the last pockets of undeveloped land.
Many West Hoxton homes are now 20 to 25 years old, and that's exactly the age when termite protection starts to change from a strength to a risk. Sealants installed at construction shrink over time, weep holes get covered by landscaping, and garden trees planted when the block was new have matured enough to overhang the roofline. Lake Francis and other local water features add mosquitoes and moisture to the mix in warm weather. A rebuild here has to account for how the block has aged since it was first built, not just what the original approval assumed would happen to it.

Local conditions
Here's what actually drives the termite risk on a West Hoxton rebuild.
Termite systems installed when West Hoxton was first developed in the late 1990s and early 2000s are now 20 to 25 years old, right at the point where sealants and barriers commonly start to fail. A rebuild is the right moment to replace that ageing protection with a fully compliant new system rather than assume it still holds.
Two decades of garden growth and hardscaping is enough time for weep holes and slab edges to end up buried under paving, garden beds or raised planters. Part of scoping a West Hoxton rebuild is checking what's been covered over the years, since a hidden weep hole is a common place for concealed termite entry to go unnoticed.
Lake Francis and other water features around West Hoxton add moisture to nearby blocks and support mosquito breeding in warm weather. Ground close to any of these features tends to stay damper for longer, so we extend soil treatment further around low-lying sections of the perimeter on blocks near the water.
What we install here
We handle West Hoxton knockdown rebuilds and renovations on the suburb's late-1990s and early-2000s housing stock, plus new homes on the last remaining undeveloped pockets. Most sites take a standard waffle pod or raft slab, and we get collars on as soon as the plumber has signed off the rough-in. Quotes come as one number worked out from your plans, timed to wrap up well before the concreter needs the site clear for the pour.
Local knowledge
A good share of our West Hoxton work sits near Puntillo Park, where established twenty-something-year gardens have had time to grow over original slab edges and weep holes. Around Carnes Hill Marketplace and the Michael Clarke Recreation Centre, food waste and irrigated sports fields add rodent and mosquito pressure that we factor into nearby jobs. Toward Lake Francis, damp ground gets closer attention to drainage and perimeter treatment on rebuilds near the water.
Liverpool City is the certifying council for West Hoxton, and it won't release an Occupation Certificate without documented proof the termite system meets AS 3660.1. Once installation is complete we mount the required notice in the meter box and issue a certificate covering the installer, the products and the areas treated, so your certifier has a complete file to work from.

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.
For: certifier, owner, future owners
Written confirmation of the system and products used, the areas protected and our licence details.
For: builder, certifier, owner
Details of the physical system or termiticide installed, including safety data sheets for any chemicals.
For: builder, owner

West Hoxton questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215On a knockdown rebuild, yes, since whatever protection was installed when the suburb was first developed is now old enough that sealants have likely shrunk and weep holes may have been covered by landscaping. We treat the rebuild as a fresh install and check the old system's condition rather than assuming it's still working.
Ground close to the lake and other local water features stays damper for longer than blocks further away, and that persistent moisture is what subterranean termites use to forage. We extend the treated zone further around any low-lying corner of the perimeter on blocks near the water, and check drainage carefully before pricing the job.
Before demolition, where we can, we walk the existing structure looking for garden beds, raised planters or paving that has crept up over what used to be a clear, ventilated slab edge. Anything buried like that gets noted and built into the new perimeter plan, so the same mistake isn't repeated once fresh landscaping goes back in.
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.
