Pre-Construction Termite Barriers Across Northwood
What we cover in Northwood, and how quickly we can get there.
Northwood sits about 5.5 km north-west of the CBD in the Lower North Shore, and postcode 2066 is one we are in most weeks. Our technicians are through Northwood most days, so same-day attendance is usually available.
Around Northwood we work the pockets near Mall 88, Wollstonecraft station and St Leonards station most often, so the van is rarely far away when a job comes in.
The suburb sits in the North Sydney, Mosman, Willoughby, Lane Cove and Hunters Hill area. Greenwich, Osborne Park and Longueville are all covered on the same day, so a problem that has spread across a boundary can be handled in one visit. The mix here is older houses and converted blocks near the water, where moisture under the floor is usually part of the story.
The termite calls we take from Northwood are mostly waterfront and near-waterfront homes with damp sub-floors and mature gardens. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Our Northwood runs also take in Lane Cove Bushland Park and the area near Osborne Park, so the whole postcode is served.

OVERVIEW
Pre-Construction Termite Barriers Done Right the First Time
If a system is going to fail it fails at a detail, not across the whole footprint. That is why we photograph each penetration and each stage as it is completed.
People expect a barrier to be a wall. It is a managed zone: termites either cannot cross it or must build visible workings to do so.
A barrier is only as good as its weakest penetration. One untreated conduit gives a colony a clean route into the frame.
- A fixed quote worked up from your plans
- Installation staged around your build program
- Physical systems, chemical systems, or a combination
- Durable notice and installation certificate, ready for the certifier
SYSTEMS WE INSTALL
Termite Barrier Systems We Install in Northwood
Photos from our own Sydney installations, not stock images. We recommend the right mix for your slab design, site and budget.
Full Under-Slab Membrane
A physical, termite-resistant membrane laid over the prepared ground ahead of the pour, covering the slab's entire footprint.
Penetration Collars
Every penetration through the slab is collared and sealed. These are the hidden entry points termites use most.
Perimeter & Slab Edge Barrier
A physical barrier around the slab edge and into the wall cavity, which stops termites building concealed tunnels up the outside of the slab.
Chemical Soil Barrier & Reticulation
APVMA-registered termiticide applied to the soil, with the option of a reticulation pipe network so the barrier can be recharged later without digging.
Suspended Floors & Piers
On a sloping or elevated site, the bearers, piers and suspended timber floor are all protected.
Retaining Walls & Complex Sites
Specific detailing where there are retaining walls, sandstone excavation, step-downs or cut-and-fill, as is common across Sydney.
WHY DURING THE BUILD
Why Install During Construction in Northwood
Once the slab is poured, the areas termites use most are sealed away for good.
A Fraction of the Cost
Compared with a retrofit - or with repairing damage - a pre-construction barrier is a small cost.
Required by the NCC
New homes (Class 1) and outbuildings (Class 10) with termite-susceptible primary building elements need a compliant termite management system.
Hidden Entry Points Sealed
Before the pour is the only opportunity to fully protect the pipe penetrations and slab joints.
Whole-Footprint Protection
There are areas no later treatment can reach - an under-slab system covers them.
No Occupation Certificate Delays
Your certifier needs the installation certificate and durable notice before issuing the Occupation Certificate.
Resale Confidence
Buyers, building inspectors and lenders all take comfort from documented, compliant termite protection.

COMPARE SYSTEMS
Physical vs Chemical Termite Barriers in Northwood
Both approaches can comply with AS 3660.1. Many Sydney builds use a combination.
| System | How it works | Durability & upkeep | Best suited to |
|---|---|---|---|
| Physical membrane, mesh or graded stone | Sheet membrane, stainless mesh or graded stone particles form a layer termites cannot pass, under the slab or at the perimeter | Lasts as long as the slab unless disturbed, and never needs a chemical top-up | Slab-on-ground homes, and anyone wanting a non-chemical system |
| Penetration collars | A physical collar sealed around every pipe and conduit crossing the slab | Long service life when fitted properly ahead of the pour | All slabs. Usually combined with a perimeter system. |
| Chemical soil barrier | Soil treated with termiticide to form a zone under and around the structure | Service life depends on label and soil, with re-application possible | Budget-conscious projects and certain complex sites |
| Reticulation system | Pipework installed before paving so the soil can be re-treated by pumping | Can be topped up for the life of the building with no excavation of paths | Houses surrounded by paving or landscaped areas |
| Baiting (post-construction) | In-ground monitoring stations that eliminate the colony | Stations need regular servicing | Existing homes, see termite control |
INSTALLATION STAGES
How a Pre-Construction Barrier Is Installed in Northwood
Termite barriers are installed in stages that follow the build, not in a single visit.
01
Plan Review & Fixed Quote
With your plans and slab details we recommend a system and price every stage, fixed.
02
Stage 1: Before the Pour
All service penetrations are collared, and the under-slab membrane or chemical treatment goes in once the site is prepared.
03
Stage 2: Slab Edge & Cavity
Perimeter and cavity barriers installed as the brickwork or cladding goes up, so there is no gap at the slab edge.
04
Stage 3: Final Perimeter
Where specified, a chemical perimeter or reticulation system is completed around the finished building before paving and landscaping.
05
Durable Notice & Certificate
The system is recorded on a durable notice fixed in the meter box, and the installation certificate goes to the builder and the certifier.
06
Handover Advice
Maintenance advice and an inspection schedule go to the owner, so the system keeps doing its job.
PAPERWORK
Documents You Receive at Handover in Northwood

FOR BUILDERS
For Builders, Developers & Owner-Builders
Coordinating with your trades
Our scheduling follows the plumber's set-out and the concreter's pour date. Once services are in, tell us and we confirm collars before the pour inspection.
- Penetration collars before the pour
- Slab edge and cavity barrier going in with the walls
- Perimeter done before any paving goes down
Multi-unit and repeat work
We give developers and volume builders consistent pricing, one contact, and documentation lot by lot.
Avoiding certification delays
A missing durable notice or unclear installation record is a common cause of occupation certificate delay. We supply the lot together so the certifier has everything.
AFTER HANDOVER
How to Keep Your Termite Barrier Effective in Northwood
A barrier only works if it stays intact and visible. Homeowners should follow these points for the life of the building.
- Leave 75 mm or more of the slab edge visible as an inspection zone - no soil, mulch or paving over it.
- No garden beds built against the house, and no timber stacked on it
- Weep holes need to stay open, with no render or debris blocking them
- Get leaking taps, downpipes and hot water units near the building fixed
- Let your builder or installer know before anything is drilled through the slab
- Check that new pipes or extensions are protected too
- Have a timber pest inspection at least every 12 months
- Store the durable notice and installation certificate with the property papers
PRICING FACTORS
What Affects the Cost of a Termite Barrier in Northwood
| Factor | Why it matters |
|---|---|
| Slab area & perimeter length | The bigger the footprint, the more membrane, perimeter protection and labour required |
| System chosen | Full under-slab physical, perimeter-only, chemical and reticulation options are each priced differently |
| Number of penetrations | A collar is needed for each plumbing and electrical penetration through the slab |
| Difficulty of the site | Retaining walls, step-downs, sandstone excavation and suspended floors add to the detailing |
| Site visits required | Staging follows the build program; multi-dwelling sites may be combined into fewer visits |

SYDNEY NEW BUILDS
Termite Protection for Sydney New Builds in Northwood
Reactive soil is the argument for a system that tolerates movement rather than a rigid one. We choose based on the soil report for the Northwood site, not on a default.
Estates built on cleared farmland inherit the colonies already living in that soil. A new Northwood house is not a fresh start from a termite point of view - it is a new food source on an established site.
Pre-purchase inspections ask about the system and the notice. Having both in order removes a negotiating point from the buyer's side.

FAQ
Pre-Construction Termite Barriers Questions, Answered
Everything you need to know before you book. Still unsure? Call us — we're happy to help.
Get a Free QuoteWhat does pre-construction termite barriers cost in Northwood?
Barriers are quoted off your plans and slab details. Two things move it: how big the place is, and how far it has already spread. We work that out on the phone or on site and tell you the figure before anything starts in Northwood. You get the AS 3660.1 certificate and the durable notice for the meter box.
What is the wait for a technician in Northwood?
Same-day attendance is usually available. We are about 5.5 km north-west of the city here, and Northwood is covered by the Lower North Shore team.
What makes Northwood prone to termites?
Harbourside blocks are often steep, with the lower level cut into the slope. Those lower levels stay cool and damp, which is where we usually find termites.
What sort of properties do you treat in Northwood?
Period stock on sloping blocks. The lower level and the sub-floor do most of the explaining.
Can you do a rental or a strata property in Northwood?
Yes. Houses, townhouses, units, strata common property, rentals and commercial sites in Northwood 2066 are all part of what we do, and the paperwork is the kind agents accept.
Is it safe for kids and pets?
Yes. The products are registered for this use and applied at label rates, and placement keeps them away from where children and animals go. Let us know at booking about pets, fish tanks or anyone with asthma and we will plan the visit around it.
Can we stay home while the treatment is done?
Usually not. Most of the work is done with you in the house, and where a room does need to be clear it is for a short period we will tell you about on arrival.
How much time should I allow?
For a standard Northwood home, one to two hours. We would rather tell you it will take longer up front than rush it.
What if the termites come back?
You get the AS 3660.1 certificate and the durable notice for the meter box. That is the point of the warranty - you do not pay twice for the same problem.
Do you cover the suburbs around Northwood too?
We do. Northwood and Greenwich, Osborne Park, Longueville and Riverview are all on the same route, which helps if you own more than one property in the area.
