Upper North Shore · AS 3660.1
Perimeter barriers and under-slab systems fitted to Pymble's heritage and unit sites, installed before the pour on streets running from the station precinct to remnant tall forest reserves.
Quick answer
Yes. Pymble sits close to remnant tall forest, so a new home, unit or rebuild needs an NCC termite management system installed to AS 3660.1. Collars and under-slab work go in after the plumber's rough-in and before the pour. The durable notice for the meter box and an installation certificate for Ku-ring-gai Council are both needed before the Occupation Certificate is issued.
Termite barriers in Pymble
Pymble is a Ku-ring-gai Council suburb about 15 km north-west of the CBD, in postcode 2073. Development began around 1879, and the suburb holds heritage houses from the 1870s to the 1930s, including a Walter Burley Griffin design, alongside later family homes. Most dwellings are separate houses, with about a quarter units, and Pymble station sits on the North Shore line with shops clustered near Grandview Street and the Pacific Highway, plus commercial precincts around Bridge Street and West Street. Our work spans heritage home rebuilds and unit or commercial construction close to the station.
Remnant forests such as Dalrymple-Hay Nature Reserve and Sheldon Forest survive within the suburb, and tall, established trees like these keep the surrounding ground shaded and moist well into the drier months. That combination of old growth forest and Pymble's early heritage housing gives termites plenty of established habitat close to residential streets. Apartments and commercial buildings nearer the station and highway face a different job again, with multi-dwelling slabs and a higher number of penetrations to collar on a single pour. We check both settings carefully, since old growth forest and multi-dwelling construction call for very different barrier details.

Local conditions
Three things shape termite risk in Pymble, tied to its remnant forest reserves and its long development history.
These patches of remnant tall forest keep nearby ground shaded and moist for longer than open suburban blocks, supporting established colonies that forage through fallen timber and leaf litter. Rebuilds near either reserve get a full perimeter system rather than a partial strip.
Pymble's oldest homes, including a Walter Burley Griffin design, date back well over a century, and any original termite protection on these properties is long past being relied on. A rebuild or major renovation needs a fresh, documented termite management system tied into the existing structure.
Apartments and commercial buildings near Pymble station and the Pacific Highway carry more service penetrations on a single slab than a detached home. Collar counts and scheduling around the builder's program drive the price and timing on sites like these.
What we install here
We work on Pymble heritage home rebuilds and renovations near the remnant forest reserves, unit and commercial developments closer to the station, and granny flats on established blocks. Suspended floors and piers turn up on the larger, tree-covered blocks, alongside waffle pod and basement-level slabs on unit and commercial sites. You get one fixed written quote from the plans covering every stage, and we attend in stages so a barrier visit never holds up a pour.
Local knowledge
Our Pymble work runs from the station precinct near Robert Pymble Park, where unit and commercial construction drives collar scheduling, out toward Dalrymple-Hay Nature Reserve, where remnant tall forest shapes how far the perimeter needs to extend on nearby rebuilds. Around Gordon Golf Club, irrigated turf keeps some neighbouring blocks damper for longer. We check heritage sub-floors and multi-dwelling penetrations with equally close attention on every Pymble job.
Ku-ring-gai Council will not grant an Occupation Certificate for a Pymble property without a durable notice inside the meter box and a certificate from the installer covering the products, the coverage and the licence held. We have both ready as soon as our stage of a Pymble job, house, unit or commercial build, is finished.

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 215They need more attention to the perimeter rather than a different product. Remnant tall forest like this keeps ground shaded and moist, supporting established colonies that forage into nearby gardens, so we run a full perimeter system on blocks near either reserve. That attention includes checking any retaining wall or step-down where the block meets the reserve boundary.
Yes. Homes dating back to the 1870s, including some notable heritage designs, are well past the point where any original termite protection can be relied on. We treat a rebuild or major renovation on one of these properties as a fresh job, with its own documented termite management system. We check the existing sub-floor before finalising the scope of any new work.
The same NCC requirement applies, but the job is scaled differently. A multi-dwelling slab near the station can carry more service penetrations than a single home, so we plan collar counts and our attendance around the builder's program for the whole site. We confirm penetration counts and access timing with the builder before our visit to the site.
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.
