LOCAL COVERAGE
Pre-Construction Termite Barriers in North Wahroonga
Where North Wahroonga sits, who covers it and what it costs.
Our Upper North Shore technicians cover North Wahroonga and the rest of 2076 as a matter of course - it is only about 20.2 km north of the city. We run North Wahroonga on a regular route, and same-day attendance is usually available.
Our North Wahroonga work takes in the streets by Palmerstone Centre and Asquith Golf Club, through to Eric Evans Park at the other end.
North Wahroonga is in the Ku-ring-gai and Hornsby area, and we cover North Turramurra, Asquith and Wahroonga on the same runs - handy if you own more than one property or your termite problem has come from next door. With bushland close by there is constant pressure from outside, so the perimeter and the fence line get as much attention as the house.
What we see in North Wahroonga is properties where the fence line matters as much as the kitchen. Describing it accurately when you book saves a second visit.
Wahroonga Reserve and the remainder of 2076 are on the same run.

OVERVIEW
Pre-Construction Termite Barriers Done Right the First Time
The value of the system on a North Wahroonga home is detectability. Without the inspections that detectability is never used.
The failures we are called to inspect are rarely the product. They are a collar missed on a late-added pipe, a perimeter left short at a step-down, or a membrane torn by a trade after we left and never reported.
Tell whoever does the landscaping on your North Wahroonga build to keep soil, mulch and paving below the slab edge. It is the single most common way a good system is quietly defeated.
- A fixed quote worked up from your plans
- Staged installation that fits your build program
- Physical systems, chemical systems, or a combination
- Durable notice plus certificate, for the certifier
SYSTEMS WE INSTALL
Termite Barrier Systems We Install in North Wahroonga
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 sheet membrane that termites cannot pass, laid across the prepared ground before the pour so the entire footprint is covered.
Penetration Collars
Each pipe, conduit and service crossing the slab is sealed with a collar - penetrations being the most common concealed entry.
Perimeter & Slab Edge Barrier
A barrier around the slab edge and into the wall cavity prevents termites tunnelling unseen up the slab's outer face.
Chemical Soil Barrier & Reticulation
A soil-applied APVMA-registered termiticide, with the option of reticulation pipework allowing recharge later without excavation.
Suspended Floors & Piers
On a sloping or elevated site, the bearers, piers and suspended timber floor are all protected.
Retaining Walls & Complex Sites
Detailing for the complications Sydney blocks throw up: retaining walls, sandstone excavation, step-downs and cut-and-fill.
WHY DURING THE BUILD
Why Install During Construction in North Wahroonga
Once the slab is poured, the areas termites use most are sealed away for good.
A Fraction of the Cost
The pre-construction price is far below what a retrofit costs, and nowhere near the cost of repairing damage.
Required by the NCC
Under the NCC, Class 1 homes and Class 10 outbuildings with termite-susceptible primary building elements require a compliant termite management system.
Hidden Entry Points Sealed
Pipe penetrations and slab joints can only be fully protected before concrete covers them.
Whole-Footprint Protection
Areas no post-construction treatment can ever reach are covered by an under-slab system.
No Occupation Certificate Delays
Before issuing the Occupation Certificate, the certifier requires both the installation certificate and the durable notice.
Resale Confidence
Documented, compliant termite protection reassures buyers, building inspectors and lenders.
DON'T WAIT FOR IT TO GET WORSE
About to pour? Book the termite barrier before you do.

COMPARE SYSTEMS
Physical vs Chemical Termite Barriers in North Wahroonga
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 | Each pipe and conduit through the slab is sealed with a physical collar | Long-lasting, assuming correct installation before the pour | Every slab, usually in combination with a perimeter system |
| Chemical soil barrier | A treated zone created with termiticide in the soil below and around the building | The label and the soil conditions set the service life; it can be re-applied | Builds with tighter budgets, and some complex sites |
| Reticulation system | A network of pipes installed before paving so termiticide can be re-injected into the soil | Rechargeable throughout the building's life, with no need to dig up paths | Homes with paving or landscaping all around them |
| Baiting (post-construction) | Ground stations for monitoring, then baiting to eliminate the colony | The stations must be serviced regularly | Existing homes - see termite control |
INSTALLATION STAGES

FOR BUILDERS
For Builders, Developers & Owner-Builders
Coordinating with your trades
We fit in around the plumber's set-out and the pour. Tell us once services are in and the collar installation is confirmed before the pour inspection.
- Collars to every penetration before concrete goes down
- Slab edge and cavity barrier as walls go up
- Perimeter done before any paving goes down
Multi-unit and repeat work
For developers and volume builders: consistent pricing, one point of contact, and documentation issued for every lot or dwelling.
Avoiding certification delays
Occupation certificates are often held up by a missing durable notice or vague installation records. Everything is supplied together so the certifier is not left chasing.
AFTER HANDOVER
How to Keep Your Termite Barrier Effective in North Wahroonga
A barrier only works if it stays intact and visible. Homeowners should follow these points for the life of the building.
- The inspection zone needs 75 mm of slab edge left exposed - don't cover it with soil, mulch or paving.
- Keep garden beds and stacked timber away from the house
- Keep the weep holes clear of render and debris
- Repair any leaking tap, downpipe or hot water unit near the house
- Tell the builder or installer first if the slab needs drilling
- Any new pipes or extensions should be protected as well
- Book a timber pest inspection at least once every 12 months
- The durable notice and installation certificate belong with your property records
PRICING FACTORS
What Affects the Cost of a Termite Barrier in North Wahroonga
| Factor | Why it matters |
|---|---|
| Slab size and perimeter run | Larger slabs need more membrane and perimeter protection, and more labour |
| System type | Full under-slab physical systems, perimeter-only systems and chemical or reticulation options are priced differently |
| Number of penetrations | A collar is needed for each plumbing and electrical penetration through the slab |
| Site complexity | Retaining walls, step-downs, sandstone excavation and suspended floors add detailing |
| How many attendances | Staged installations follow the build program, and multi-dwelling sites may be combined |

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 am I looking at for pre-construction termite barriers in North Wahroonga?
Barriers are quoted off your plans and slab details. What changes the figure is the size of the building, how many areas are affected and the access. You get that number up front for North Wahroonga 2076, with no call-out fee. You get the AS 3660.1 certificate and the durable notice for the meter box.
How quickly can you get to North Wahroonga?
Same-day attendance is usually available. We are about 20.2 km north of the city here, and North Wahroonga is covered by the Upper North Shore team.
Why do termites keep coming back in North Wahroonga?
Properties on a bush edge get re-supplied continuously. That is why our work in North Wahroonga is as much about the fence line and the perimeter as the inside of the house.
What kind of buildings do you work on around North Wahroonga?
Houses on larger, often sloping blocks with bush on at least one boundary, so the perimeter and the fence line are central to the job.
Can you do a rental or a strata property in North Wahroonga?
Yes. We work in houses, units, strata blocks, rentals and commercial premises across North Wahroonga 2076, and we provide the written report agents and strata managers ask for.
Do we need to worry about pets or children afterwards?
Yes, applied correctly. Products are registered for this use, placed out of reach rather than across open surfaces, and you will know what to stay off and for how long.
Do I need to leave the property during treatment?
You do not normally need to leave. Anything requiring an empty room is short, and you will know about it before the work starts.
How long does the treatment take?
Allow one to two hours for a typical North Wahroonga property. Larger homes, or ones where the problem has spread, take longer and we will say so when we quote.
What if the termites come back?
You get the AS 3660.1 certificate and the durable notice for the meter box. If it is not holding, call us - that is exactly what the warranty is for.
Is North Wahroonga inside your service area?
All of them. North Wahroonga sits alongside North Turramurra, Asquith, Wahroonga and Hornsby in our coverage, and they are serviced on the same schedule.
