Northern Beaches · AS 3660.1
Termite barriers fitted before the pour on Clareville rebuilds facing Pittwater, from the extended 1920s cottages near Taylors Point to the bushland edge of Angophora Reserve.
Quick answer
A rebuild or new home on the Clareville side of the Barrenjoey Peninsula does need a termite management system before Northern Beaches Council will issue an Occupation Certificate. The area is termite-prone, so a system built to AS 3660.1 is required, with collars and any under-slab layer finished before the pour. We supply the meter box notice and installation record once the barrier is done.
Termite barriers in Clareville
Clareville faces Pittwater on the western side of the Barrenjoey Peninsula, postcode 2107, roughly 27.5 km north of the CBD, and building work here falls under Northern Beaches Council. It borders Avalon Beach, Bilgola Plateau and Newport, and takes in Clareville Beach and the Taylors Point locality. In the 1920s the suburb was largely a place for holiday cottages, and it became a permanent residential area through the 1950s as more people owned cars. Many houses now have water frontage or views, and the heritage-listed Hy Brasil on Chisholm Road is a reminder of that earlier era. New building work here is almost always an extension of one of those older cottages or a full rebuild on the same footprint, and every one needs a compliant termite system before it can be occupied.
Clareville's pest story is the calm western shoreline rather than open surf. Low-lying land close to Pittwater stays damp, and older timber cottages that have been extended over the decades can hide joins where termites get in unnoticed, sometimes years before anyone realises. Jetties, boatsheds and sea walls add more timber and gaps close to the water. Behind the shore, slopes rise into bushland reserves with angophoras, bringing termite activity closer to backyards from the bush side as well as the water side. A barrier here has to account for both directions the termites can come from, which is why we detail the whole perimeter rather than just the water-facing edge.

Local conditions
Three things about Clareville's setting, calm water on one side and bush on the other, shape the barrier work.
Land close to Pittwater on the calm western shore stays damp for long stretches of the year, which suits subterranean termites working through the soil toward a slab or extension footing. These blocks usually need a continuous barrier rather than a partial one at the front of the property.
Many Clareville houses started as 1920s holiday cottages and have been extended more than once since. Each addition creates a join in the structure where termites can get in unnoticed, so a rebuild or new extension needs the barrier checked against the whole building, not just the new section.
Slopes rising from the shoreline into Angophora Reserve carry natural termite habitat alongside funnel-webs and possums. Blocks on that side of the suburb face pressure from the bush as well as from the damp shoreline, so the perimeter has to close both directions.
What we install here
Most Clareville jobs are extensions and rebuilds on established waterfront or near-waterfront cottages, since there is little untouched land left on the peninsula. Suspended floors and piers are common where a block steps down toward the water, with waffle pod slabs on the flatter blocks further back. We fit collars once the plumber's rough-in is done and detail the perimeter around any jetty, boatshed or sea wall timber nearby, all costed in one fixed written quote before we book the visit.
Local knowledge
Clareville Beach and Clareville Beach Reserve sit at the centre of most of our work here, where the calm water keeps the air and the ground moist for much of the year. Angophora Reserve, a short distance inland, is bushland where termites and funnel-web spiders are part of the natural habitat, and blocks between the two, the shore and the reserve, get the most thorough perimeter treatment because pressure can come from either direction.
Northern Beaches Council certifies Clareville builds, and before it releases an Occupation Certificate it wants a durable notice inside the meter box naming the termite system installed, along with a certificate recording the products, the installer's licence and exactly where the protection covers the building. On extended cottages we also note how the new work ties into the existing structure, so the certificate reflects the whole building rather than just the addition.

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.

Clareville questions

+61 450 515 215Yes, if the extension involves a new slab, footing or floor area that was not previously protected. We assess how any existing barrier on the original cottage was installed and tie the new work into it wherever the detailing allows, so you end up with one properly documented system covering the whole house rather than a gap between old and new.
Blocks close to Pittwater on the calm western shore tend to hold more moisture in the ground than blocks set further back, and that dampness lets subterranean termites travel undetected, so a physical collar and edge system generally outperforms soil treatment on its own here. Jetties, boatsheds and sea walls nearby also add timber that is worth inspecting alongside the main structure.
Bushland reserves like Angophora hold established termite activity that can move toward the nearest structure, so blocks on that side of the suburb usually need a full perimeter rather than a treatment focused only on the water-facing side. We assess which direction the pressure is most likely coming from before recommending the system for your particular block.
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.
