Northern Beaches · AS 3660.1
Wheeler Heights sits on a plateau above Narrabeen Lagoon, and we detail every barrier around where the block actually sits, from the bush-edge streets to the slopes running down toward Jamison Park.
Quick answer
Because Wheeler Heights sits on a bushland plateau above Narrabeen Lagoon, the NCC treats the whole suburb as termite-prone, and Northern Beaches Council won't issue an Occupation Certificate without a compliant system already installed. Every penetration gets a collar and the perimeter is sealed to AS 3660.1 standard ahead of the pour, and we prepare the paperwork your certifier will ask for.
Termite barriers in Wheeler Heights
Wheeler Heights is a residential suburb on an elevated plateau about 17 km north-east of the Sydney CBD, in postcode 2097 and the Northern Beaches Council area. It overlooks the southern foreshores of Narrabeen Lagoon, with Jamison Park stretching along the lagoon edge and the Narrabeen Lagoon Trail nearby, while reserves such as South Creek, Ambleside, Lantana and Grasmere protect patches of dry sclerophyll forest with banksias, wattles and tea-trees. The suburb has a local shopping centre, schools and a newer mixed-use building with apartments above shops. Our work here is mostly knockdown rebuilds and extensions on freestanding houses of different eras, with some apartment work near the shops.
Living on a plateau above a lagoon, surrounded by bushland reserves, shapes pest risks here in a specific way. Bush edges bring termites, funnel-web spiders and possums close to houses, while slopes running down toward the lagoon collect moisture in lower yards that keeps soil damp for longer. Extensions and decks built onto older houses can create hidden termite entry points where the new structure meets the original one, and it's worth checking those junctions as carefully as the rest of the building. Streets closer to the shopping centre and apartments add a smaller pocket of rodent and cockroach pressure on top of the bushland issues.

Local conditions
What actually shapes termite risk on a Wheeler Heights block depends heavily on where it sits on the plateau.
Reserves such as Ambleside, South Creek, Lantana and Grasmere protect dry sclerophyll forest that holds established termite colonies and funnel-web spiders in fallen timber. Blocks on a bush-facing boundary get a full perimeter system, with careful detailing anywhere a garden or deck meets the reserve directly.
Streets that fall away toward Narrabeen Lagoon and Jamison Park collect moisture in the lower parts of the yard, keeping soil damp for longer than on flatter, higher ground. Sub-floor ventilation and drainage get particular attention on these sloping blocks, since that's where termite pressure tends to concentrate.
Many Wheeler Heights houses have been extended or had decks added over different eras, and the join between an original structure and a later addition is a common place for a termite entry point to develop unnoticed. We check these junctions carefully on any job that isn't a full rebuild.
What we install here
We handle Wheeler Heights knockdown rebuilds, extensions and renovations on houses of varying ages, plus apartment work near the local shopping centre. Full rebuilds mostly take a raft or waffle pod slab, though sloping ground toward the lagoon sometimes calls for piers instead. Every job gets a single written price, and we book our visit around whatever pour or footing date your builder ends up settling on for the site.
Local knowledge
A good share of our Wheeler Heights work sits near Ambleside Reserve and Toronto Avenue Reserve, where bushland holds leaf litter and fallen timber that shelter termites and funnel-webs close to homes. Streets that fall toward Jamison Park and Narrabeen Lagoon get extra attention to sub-floor ventilation and drainage, given how much moisture collects in the lower yards. Around Augusta Shopping Centre, food waste from the retail strip adds rodent and cockroach pressure to the streets nearby.
Wheeler Heights builds are certified through Northern Beaches Council, and like any NSW certifier it wants to see a durable notice and an installation certificate before it will release the Occupation Certificate. We mount the notice permanently inside the meter box once installation is finished, and the certificate that goes with it sets out the products used, the protected areas and who carried out the work, ready for your certifier's file.

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.

Wheeler Heights questions

+61 450 515 215Yes. Reserves like Ambleside and Lantana hold established termite colonies in fallen timber, and that pressure is more concentrated on a bush-facing boundary than on a typical suburban fence line. The perimeter on these blocks runs the full boundary rather than a partial strip, and we pay particular attention wherever a garden bed sits hard against the bush.
Blocks that fall toward Narrabeen Lagoon or Jamison Park collect moisture in the lower yard, which keeps soil damp for longer than on flatter, higher ground nearby. We pay particular attention to sub-floor ventilation and drainage on these sloping sites, since that's where termite pressure tends to build up over time.
We do this regularly, since so many Wheeler Heights houses have picked up an extension or a deck at some point. The seam between the original structure and whatever was added later gets checked carefully, because that's usually where an unnoticed entry point sits, and the barrier is detailed to cover both the old footprint and the new work.
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.
