Lower North Shore · AS 3660.1
Perimeter and under-slab termite barriers installed to AS 3660.1 for Longueville knockdown rebuilds on weatherboard and waterfront blocks, on the peninsula between Tambourine Bay and Woodford Bay.
Quick answer
Yes, a rebuild or new home in Longueville needs a termite management system, since the peninsula sits in a termite-prone part of the Municipality of Lane Cove and the NCC applies regardless of the existing house style. The system is installed to AS 3660.1, with collars and under-slab work completed before the pour, and the durable notice plus installation certificate provided to your certifier before the Occupation Certificate.
Termite barriers in Longueville
Longueville is a Municipality of Lane Cove suburb about 6 km north-west of the Sydney CBD, on a peninsula between Tambourine Bay and Woodford Bay on the banks of the Lane Cove River. It is almost entirely detached houses in a wide range of styles, Victorian and Federation homes, Californian bungalows and weatherboard cottages sitting alongside contemporary waterfront houses, and Kingsford Smith Oval and the Lane Cove 12ft Sailing Skiff Club are among its local landmarks. Because there is little vacant land left on the peninsula, almost all of our work here is a knockdown rebuild or a major renovation.
That mix of older timber homes and waterfront blocks makes termites and timber decay the leading concern for a Longueville rebuild. Weatherboard cottages and bungalows can have timber cladding, floors and verandahs that termites already target, and river moisture keeps sub-floors damp on blocks close to the water. Mature gardens and established trees add fallen timber and leaf litter that hold colonies close to a rebuild site. On a peninsula this exposed to the river, a pre-construction barrier has to account for sub-floor ventilation and any retaining wall near the bank as much as the slab edge itself.

Local conditions
Three conditions shape a Longueville barrier more than most inland Lane Cove suburbs need to consider.
Longueville sits on a peninsula between Tambourine Bay and Woodford Bay, and that much river exposure keeps soil and sub-floors damper for longer than an inland block. Subterranean termites favour exactly that kind of moisture near a new slab.
Weatherboard cottages and Californian bungalows are common on the peninsula, and their timber cladding, floors and verandahs can already carry termite activity before a neighbouring rebuild even starts. We check that context during the quote, not just the rebuild block itself.
Established gardens and trees on Longueville blocks hold fallen timber and leaf litter close to the house, and waterfront retaining walls add junctions where a barrier can be missed if it is not planned before the pour. Both get detailed attention on every rebuild we quote.
What we install here
Almost all of our Longueville work is a knockdown rebuild or major renovation on an existing peninsula block, since so little vacant land remains. We install physical or chemical perimeter systems and under-slab membrane suited to river-adjacent ground, with particular care at sub-floor ventilation, weatherboard junctions and any retaining wall near the water. One fixed quote from your plans covers every stage, scheduled around your builder's pour date. We confirm access and timing with your builder before we start.
Local knowledge
Our Longueville work concentrates around Wharf Road Reserve and the foreshore near Woolwich Baths Beach, where moist air off the water keeps sub-floors and cavities damp on nearby rebuild sites. Kingsford Smith Oval and the streets around it mark the higher, drier part of the peninsula, while blocks closer to Lane Cove Country Club sit a little further from direct river exposure. Wherever the block sits, we check sub-floor ventilation and any timber touching soil.
Longueville is certified through the Municipality of Lane Cove, which requires the same termite documentation for a rebuild or new home as anywhere else: an installation certificate spells out which areas are protected, the installer's licence and what products went in, while a durable notice sits inside the meter box, both needed before the Occupation Certificate is issued. We provide both, with maintenance advice suited to a waterfront timber home.

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.

+61 450 515 215It changes what we check rather than what we install. Weatherboard cladding and old verandah timber can already carry termite activity, so we inspect the existing structure closely during the quote, then install the same collars, under-slab work and perimeter to AS 3660.1 as any other rebuild. We are happy to talk through the specifics once we see your plans.
Usually a more thorough one rather than a bigger one. River-adjacent ground holds moisture longer, which favours subterranean termites, so we generally recommend a full physical perimeter with close attention to sub-floor ventilation and any retaining wall near the water's edge. Reach out early so we can lock in a suitable date.
After the plumber has set out the drainage and before the concrete is poured, the same timing as any new slab. On a tight peninsula block we also plan around limited street access, so let us know your site constraints when you book. We keep a copy of every certificate on file for later.
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.
