Penrith & the Outer West · AS 3660.1
Perimeter barriers and under-slab systems installed before the pour across Regentville, on residential streets and larger rural-residential lots running down toward the Nepean River and Mulgoa Road.
Quick answer
Yes. A new home or rebuild in Regentville needs an NCC termite management system installed to AS 3660.1. Collars and any under-slab work go in after the plumber's rough-in and before the concrete pour. The durable notice for the meter box and an installation certificate for the City of Penrith certifier are both required before the Occupation Certificate is issued.
Termite barriers in Regentville
Regentville is a small suburb in the south ward of the City of Penrith, postcode 2745, about 52 km west of the CBD. It sits on the eastern bank of the Nepean River, with the M4 Motorway close by and Mulgoa Road as its main local route. The name comes from Regentville, the estate Sir John Jamison built here in the 1820s, a Georgian mansion with a mill, dairy, stud and vineyard, which burned down in 1868, leaving only cellars and fragments of wall behind. Regentville has stayed partly rural while newer suburbs have grown up around it, mixing standard residential streets with larger blocks and open land.
That mix of residential and semi-rural land, combined with the Nepean River running along the suburb's edge, affects how a termite barrier is planned here. Damp river flats suit subterranean termites moving through moist soil, open land on the larger blocks supports rodents and other pests, and bushland reserves nearby bring spiders and ants closer to homes. We look at the whole property, whether it is a standard suburban block or a larger rural-residential lot, and tailor the barrier to what is actually there. We check each of these conditions individually before finalising a quote for a specific Regentville property.

Local conditions
Three things shape termite risk in Regentville, tied to the river, the suburb's semi-rural land and its long history.
Sitting on the eastern bank of the Nepean River means ground near the water holds moisture for longer than the higher streets further away. We give the slab edge and drainage extra attention on blocks close to the river, since that dampness makes it easier for termites to move toward a new slab.
Regentville has stayed partly rural even as newer suburbs have grown around it, so some properties carry sheds and larger gardens well beyond a standard suburban footprint. We plan the barrier around the whole property, including outbuildings with timber near the ground.
Land around the old Regentville estate, including the cellars and wall fragments that survive from the 1820s mansion, has been settled and gardened for close to two centuries. Rebuild sites nearby often carry decades of buried timber and root systems that need proper soil treatment ahead of a new slab.
What we install here
We work on Regentville new homes, knockdown rebuilds and sheds on both standard residential blocks and larger rural-residential properties. Suspended floors and piers turn up on blocks closer to the river, alongside waffle pod slabs on the more conventional builds. You get one fixed written quote from the plans covering the whole property, and we attend around your builder's program so the barrier never holds up the pour. We ask what the property was previously used for when pricing the job.
Local knowledge
Our Regentville work sits near Forest Redgum Reserve and Gibbes Street Reserve, where bushland edges bring termites, spiders and rodents toward nearby gardens, and closer to the Penrith Homemaker Centre, where waste around shops and food outlets can support rats and cockroaches in nearby streets. On river-adjacent properties, we check drainage and damp spots near the water as part of every visit.
The City of Penrith wants a durable notice for the meter box and a signed certificate from the installer, listing the products, the coverage and the licence, before it will grant an Occupation Certificate for a Regentville property. We have both ready once our stage of the work is finished, whether the block is a standard residential lot or larger acreage.

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.

+61 450 515 215It changes how carefully drainage and the slab edge are detailed. Ground near the river holds moisture for longer than the higher streets further away, and that dampness makes it easier for subterranean termites to move toward a new slab, so we check drainage falls closely on properties near the water.
Where a shed has habitable use or sits close to the house, its timber-to-ground contact needs checking as part of the same job. Regentville's larger, semi-rural blocks often carry sheds and outbuildings, so we look at the whole property, not just the main slab. We confirm the full list of structures on the property before finalising a written quote.
Ground that has been settled and gardened since the 1820s, including land around the old Regentville estate, can carry decades of buried timber and root systems. We check the soil on properties near this history and treat it properly ahead of the under-slab system, rather than relying on the perimeter alone.
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.
