Upper North Shore · AS 3660.1
Termite barriers installed to AS 3660.1 on East Lindfield's post-war streets in postcode 2070, from the rebuild sites near Follies Park to the fairways of Roseville Golf Course.
Quick answer
East Lindfield does need a termite management system for any new home or rebuild, since the suburb sits within termite-prone Ku-ring-gai and the requirement runs under the National Construction Code. Whichever the floor type, slab or timber over a crawl space, the barrier goes in before construction is finished, and the certifier is given an installation certificate plus a durable notice for the meter box before signing the Occupation Certificate.
Termite barriers in East Lindfield
East Lindfield split away from Lindfield as its own suburb in 1994, about 10.9 km north of the CBD in postcode 2070 and part of Ku-ring-gai Council. Much of it was developed through the 1950s and 1960s, and a good number of those original houses have since been rebuilt or replaced, giving the suburb a mix of post-war brick homes and more recent builds. Most residents live in separate houses, with reserves and bushland pockets threaded between the streets, and the nearest station is over the border at Lindfield. New work here is mostly knockdown rebuilds on the older post-war blocks, along with extensions and the occasional new dwelling where a larger allotment allows it. Each of those needs a termite management system before the slab or footings are finished.
Construction era matters more in East Lindfield than in many suburbs. Post-war houses here typically have brick walls sitting on a timber-framed floor with a crawl space underneath, and that sub-floor void is where a lot of the risk sits, particularly where later renovations have blocked off ventilation that was originally left open. Rebuilds replace that construction with a modern slab, which changes the barrier entirely, from sub-floor inspection points to collars and edge protection around the new footprint. Reserves such as Nungara Reserve, one of several bushland pockets in the area, keep established growth close to some streets, adding to what a barrier on either type of house has to deal with.

Local conditions
Three things about East Lindfield's age and layout change how a termite barrier gets designed here.
Many original East Lindfield houses have brick walls on a timber-framed floor over a crawl space, and that void is a common place for activity to establish, especially where renovations have closed off the original ventilation. On these homes inspection access and airflow matter as much as any barrier.
A steady run of knockdown rebuilds is replacing East Lindfield's 1950s and 1960s houses with new slab-on-ground construction. That shift changes the barrier completely, from a sub-floor system to collars and perimeter protection around a modern footprint, so we assess each site on its own construction type.
Reserves such as Nungara Reserve sit within the suburb rather than only on its edges, keeping established bush growth close to a number of East Lindfield streets. Blocks near these pockets get the same full perimeter attention as those on a suburb's outer bushland boundary.
What we install here
East Lindfield work is a mix of knockdown rebuilds on the suburb's original post-war housing, extensions to existing homes and the occasional new dwelling on a larger block. Where an older timber-floor house remains, we assess the sub-floor and its ventilation before recommending a system; where a rebuild is going to a modern slab, waffle pod or raft construction is standard. One quote, drawn up from the plans before we start, covers the whole job regardless of floor type, and our visit is timed around your plumber's rough-in and the concreter's pour date.
Local knowledge
Follies Park, about 0.3 km away, and Nungara Reserve, a little further out, are among the bushland pockets that sit close to East Lindfield streets rather than only on the suburb's edge, and rebuild sites near either get closer perimeter attention. Roseville Golf Course, about 0.6 km away, keeps a large area of irrigated turf nearby, and Lindfield Shopping Village and Roseville station mark the commercial and transport edge of the suburb, just over the border.
East Lindfield sits under Ku-ring-gai Council for certification purposes. Before signing the Occupation Certificate, the certifier wants a durable notice fixed inside the meter box together with an installation certificate recording the products, the areas covered and the licensed installer. Where a rebuild replaces an older timber-floor house, we flag the change in construction type on that certificate, since it affects how the property should be inspected and maintained afterward.

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

East Lindfield questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215The construction type changes what we install, not whether protection is needed. A timber floor over a crawl space relies on inspection access and ventilation as much as any barrier, so we check both and recommend a system suited to that construction rather than assuming a slab-based approach will fit.
Yes, in most cases. Demolishing an original post-war house and building on a new slab means the old sub-floor arrangement no longer applies, so the new termite management system is designed around collars, membrane and perimeter protection sized to the modern footprint, installed before the concrete work is finished and documented fresh for the certifier rather than carried over from the old house.
Blocks close to a bushland pocket like Nungara Reserve get more attention to the perimeter, since established growth there can carry activity toward a new build in a way an ordinary neighbouring garden does not. We still install the same core system, just with a fuller perimeter and more careful detailing along that boundary.
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.
