Penrith & the Outer West · AS 3660.1
Werrington County's homes are now around 40 years old, so we build the barrier around what's already on the block, from the creek-side streets to the shops near Werrington Lakes.
Quick answer
Yes. Werrington County falls within a termite-prone area under the NCC, which is why a new home or knockdown rebuild here cannot get its Occupation Certificate without a termite management system already installed. Built to AS 3660.1, that means collars fitted and the perimeter closed off before the concrete pour, followed by paperwork for your Penrith certifier.
Termite barriers in Werrington County
Werrington County is a residential suburb in the north ward of the City of Penrith, postcode 2747, about 45 km west of the Sydney CBD. It was farmland under an 1806 land grant until housing went in during the early 1980s, and the suburb sits on higher ground than much of Penrith, with Werrington Creek along its eastern side and Werrington Lakes in the south-west corner. Almost all of our work here is knockdown rebuilds, since the suburb is entirely residential and was built out in one era rather than in stages.
Most Werrington County homes are now around 40 years old, and that age matters more than almost anything else on a rebuild here. Original termite protection from the early 1980s has generally reached the end of its working life, and garden additions such as paving and pergolas can have covered slab edges that once had clear inspection access. Werrington Creek and the lakes add moisture and vegetation on the suburb's edges that suit termites well, so blocks near either feature need particular care on the perimeter, on top of the general attention every rebuild here needs given the age of the housing stock.

Local conditions
Three things push termite risk higher on a Werrington County rebuild than the age of the suburb alone would suggest.
Homes built here in the early 1980s are now around 40 years old, well past the working life of whatever termite protection went in at construction. A rebuild needs a properly new system rather than relying on remnants of the old one, and we treat every site as a fresh install.
Werrington Creek runs along the suburb's eastern side and Werrington Lakes sits in the south-west corner, and both keep nearby ground damp for longer than blocks in the middle of the suburb. That persistent moisture is what subterranean termites forage through, so we extend coverage further around low-lying corners near either feature.
Forty years is enough time for paving, pergolas and garden beds to have crept over what was once a clear, inspectable slab edge. Part of a Werrington County rebuild is working out what's been covered over the years, since a hidden slab edge is where an existing termite entry point is most likely to have gone unnoticed.
What we install here
Werrington County work for us is almost entirely knockdown rebuilds, since the suburb was built out in a single era in the early 1980s and has stayed that way. Waffle pod and raft slabs are standard, and collars go on once the plumber's rough-in for the new dwelling is finished. Pricing comes as one figure off the plans, with the barrier visit timed to finish ahead of the concreter regardless of what your builder's program ends up looking like.
Local knowledge
Much of our Werrington County work sits near John Batman Reserve and the neighbourhood shopping village, where established gardens from the original 1980s development have had four decades to mature. Closer to Dunheved Golf Club and the Penrith Valley Regional Sports Centre, irrigated turf adds further moisture that we account for on nearby blocks. Toward Werrington Creek and the lakes on the suburb's edges, low-lying ground gets the closest attention to drainage and slab-edge treatment.
Werrington County sits under the City of Penrith for certification purposes, and its sign-off process for the Occupation Certificate always checks for a properly documented termite system. That means a notice mounted in the meter box plus a certificate setting out what was installed, which areas it protects and who did the installing, both provided with the relevant product paperwork once the job wraps up.

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.

+61 450 515 215In almost every case, yes. Original termite protection installed here in the early 1980s has reached or passed the end of its useful life, so a rebuild is the right time to put in a fresh, fully compliant system rather than assume the old one is still doing anything useful. We treat it as a new install regardless of what protection the original house may have had.
Yes. Ground close to either feature holds moisture for longer than blocks in the middle of the suburb, and that's exactly the condition subterranean termites look for. We extend the treated zone further around any low-lying section of the perimeter and pay particular attention to drainage where the block slopes toward the water.
It's common enough on 40-year-old blocks that we always check for it before pricing a rebuild. If garden additions have covered what was once an inspectable slab edge, we factor that into the new perimeter design so the fresh system isn't compromised by whatever landscaping goes back in around the new build.
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.
