Upper North Shore · AS 3660.1
Collars, under-slab membrane and perimeter barriers installed to AS 3660.1 for Lindfield knockdown rebuilds and apartment stages, from the Sir Phillip Game Reserve bushland edge to the Lindfield station precinct.
Quick answer
Yes, a new home, rebuild or apartment building in Lindfield needs a termite management system, because the suburb lies in a termite-prone part of Ku-ring-gai Council and the NCC requires a compliant system wherever that applies. It is installed to AS 3660.1, with collars and any under-slab work completed before the pour, and the durable notice and installation certificate supplied to your certifier ahead of the Occupation Certificate.
Termite barriers in Lindfield
Lindfield is a Ku-ring-gai Council suburb about 11 km north of the Sydney CBD, in postcode 2070, known for its Californian Bungalow and Federation homes in double brick and tile, though apartments now make up a large share of dwellings, particularly around Lindfield station. Shops cluster along Lindfield Avenue and the Pacific Highway, and the former UTS Kuring-gai campus has been converted into Lindfield Learning Village. Our work here splits fairly evenly between knockdown rebuilds on established blocks and apartment or townhouse stages near the shops and station. That local knowledge shapes every quote we put together.
Bushland connected to Lane Cove National Park and Garigal National Park reaches into parts of Lindfield, and that bush edge is where subterranean termite colonies establish themselves in old stumps and leaf litter before moving toward the nearest slab. Double brick construction resists some pests well, but even a double brick home still has timber roof framing, floor joists and joinery that termites will attack once they find a way in, and decades-old gardens on rebuild blocks often hide buried timber from a previous house. Apartment sites near the station bring a different demand, a single slab with many penetrations, where collar counts matter more than bushland proximity.

Local conditions
Three conditions shape termite risk across Lindfield, and they point in different directions depending on where you are building.
Bushland connected to Lane Cove and Garigal National Parks reaches into parts of Lindfield, holding established termite colonies close to some residential blocks. Rebuilds near that edge get a full perimeter, with particular care at any retaining wall or step-down.
Double brick construction is common in Lindfield, but the roof framing, floor joists and joinery are still timber, and rebuild blocks often carry buried timber from a previous house. We treat the soil and detail the slab edge as if that history matters, because it does.
Apartment and townhouse sites near Lindfield station and the shops are typically a single slab carrying many plumbing and service penetrations. Every one needs a collar and a correctly lapped membrane, so we work from the plumbing plans to schedule collar counts ahead of the pour.
What we install here
We work on Lindfield knockdown rebuilds on established Federation and post-war blocks, granny flats behind existing houses, and apartment or townhouse stages near the station and Lindfield Learning Village. Waffle pod and raft slabs are the norm on rebuild sites, with suspended sections where a block falls toward a bushland gully. We attend after the plumber's rough-in for collars and under-slab work, and again at the perimeter stage, all from one fixed quote covering every stage of your build.
Local knowledge
Most of our Lindfield work is within a few streets of Sir Phillip Game Reserve, one of the bushland pockets that can bring termites toward a rebuild site, and Millwood Park, where garden cover sits close to several boundaries. Around Lindfield station and Lindfield Shopping Village, the work is more often an apartment or townhouse podium with a higher collar count. Blocks near Lindfield Learning Village and the old campus grounds sit at the edge of both worlds.
Lindfield builds are certified through Ku-ring-gai Council, which requires the standard termite documentation before it will issue an Occupation Certificate: a durable notice fixed in the meter box recording the system, and an installation certificate naming the products used, the areas protected and the installer's licence. We hand over both, along with product information and maintenance advice, so your sign-off is never held up waiting on us.

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.

Lindfield questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. Brick walls do not stop subterranean termites, which travel through the soil and up timber framing, floor joists and joinery regardless of what the walls are made of. Any new slab in Lindfield needs a compliant system installed to AS 3660.1, whatever the finished construction looks like. We are happy to talk through the specifics once we see your plans.
We generally recommend a full physical perimeter rather than a minimal strip, since bushland edges like that hold established termite colonies with a short path to a new slab. Retaining walls and any step-down where the block meets the bush also get particular attention during installation. Reach out early so we can lock in a suitable date.
Yes, that is regular work for us. We take the collar count from the plumbing and service drawings before the pour, attend in one visit to fit every penetration, and provide a single installation certificate covering the whole slab for your certifier. 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.
