Upper North Shore · AS 3660.1
Weatherboard cottages, additions and full rebuilds all need different handling in West Pymble, and we scope each one on the block, from Philip Mall out to the edge of Lane Cove National Park.
Quick answer
Every new home in West Pymble needs a termite management system in the ground before it can be occupied, an NCC requirement that applies right across Ku-ring-gai given how much bushland borders the suburb. In practice that means collars on every pipe penetration and a continuous perimeter closed off before the concrete pour, built to AS 3660.1, with a certificate handed to your certifier once the work is done.
Termite barriers in West Pymble
West Pymble is a Ku-ring-gai Council suburb about 14 km north-west of the Sydney CBD, in postcode 2073, where nearly all dwellings are separate houses. Most of the suburb was developed in the 1950s and 1960s, originally with three-bedroom weatherboard cottages, many of which have since been extended or replaced by larger homes. Lane Cove National Park surrounds much of the suburb, and Bicentennial Park, built over a regenerated former quarry, adds ovals and pools nearby. Our work here ranges from full knockdown rebuilds to extensions on original weatherboard homes, with the odd granny flat where a block has the room.
Weatherboard cladding, timber frames and shallow sub-floors are all directly accessible to termites, which makes the original 1950s and 1960s housing stock here particularly worth checking carefully. Where cottages have been extended over the years, the join between the old structure and the new addition often leaves a gap that a standard inspection can miss. Add streets running right up against Lane Cove National Park, which brings funnel-webs, ticks and possums as well as termites, and a West Pymble job needs both the original building and any later additions checked properly before we can size the barrier correctly.

Local conditions
Here's what pushes termite risk up on a West Pymble property more than the suburb's leafy reputation might suggest.
National park surrounds much of West Pymble, and its bushland holds established termite colonies in fallen timber and leaf litter close to residential fence lines. Blocks on that boundary get a full perimeter system, with particular care at any point where a garden bed backs directly onto the park.
The three-bedroom weatherboard cottages that make up much of West Pymble's original housing stock have timber cladding and frames directly exposed to termites, unlike a brick veneer home. Extensions and renovations on these cottages need the join between old and new structure checked as carefully as the rest of the building.
Where an original cottage has been extended, the seam between the old slab or stumps and the new footing is a common place for a gap to develop unnoticed. We treat these junctions as a priority on any West Pymble job involving an addition rather than a full rebuild.
What we install here
We handle West Pymble knockdown rebuilds, extensions and renovations on the suburb's original weatherboard stock, and granny flats on blocks with room to spare. Waffle pod and raft slabs suit most full rebuilds, while extensions often need a suspended floor tied carefully into the existing structure. Pricing is one figure off the plans, and we schedule around your builder so the barrier visit finishes well ahead of the pour or the extension's footing stage.
Local knowledge
A good share of our West Pymble work sits near Sequoia Park, where established plantings shelter ants and spiders close to older weatherboard homes. Lane Cove National Park's bushland extends around much of the suburb beyond the park's formal boundary, bringing termites, funnel-webs and possums close to many houses on the fringe. Toward Macquarie Centre, the largest nearby retail source of food waste, rodent pressure increases in the streets closest to that end of the suburb.
Ku-ring-gai Council handles certification for West Pymble, and before it will sign off the Occupation Certificate it wants clear evidence the termite system meets AS 3660.1. Once collars, membrane and perimeter are in, we mount a durable notice inside the meter box and prepare a separate installation certificate covering the products used, the areas protected and who carried out the work, so your certifier has a complete file without needing to chase anything.

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.

West Pymble questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes, since timber cladding and framing give termites direct access in a way a brick veneer home doesn't. Where a cottage has been extended, we pay particular attention to the join between the original structure and the addition, because that seam is a common place for a gap to have gone unnoticed for years.
Blocks on the park boundary face more established colony pressure than those set further back, since the bushland has held termite activity in fallen timber and leaf litter for a long time. We run a full perimeter on these blocks and look closely at any point where a garden bed meets the park directly.
Yes, and it's a common job here given how many original cottages have been extended over the decades. We check the existing structure's condition as well as the new footing, since the join between old and new work is where problems most often start, then detail the barrier to cover both sections properly.
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.
