LOCAL COVERAGE
Pre-Construction Termite Barriers in Castlecrag
What we cover in Castlecrag, and how quickly we can get there.
Our Lower North Shore technicians cover Castlecrag and the rest of 2068 as a matter of course - it is only about 7.6 km north of the city. Our technicians are through Castlecrag most days, so same-day attendance is usually available.
A lot of our Castlecrag jobs are in the streets around Northbridge Plaza and Northbridge Golf Club, and we are out near Cortile Reserve regularly enough that the technician usually knows the access before they arrive.
The suburb sits in the North Sydney, Mosman, Willoughby, Lane Cove and Hunters Hill area. Northbridge, Willoughby East and Middle Cove are all covered on the same day, so a problem that has spread across a boundary can be handled in one visit. Period homes near the harbour tend to have sub-floors, original timber and gardens running down to the boundary, so the inspection covers well beyond the kitchen.
Castlecrag jobs tend to be older homes near the water with a sub-floor that never fully dries. Let us know which when you ring and we will plan the visit around it.
Harold Reid Reserve and Clive Park Beach are on the same round, which means every part of 2068 is within our area.
When you book, we confirm the 2068 run the day before and give you an arrival time rather than a window. If we are already out at Northbridge or Willoughby East that morning, we will usually offer you the earlier slot.

OVERVIEW
Pre-Construction Termite Barriers Done Right the First Time
Most Castlecrag builds are waffle pod or raft, and the two are detailed differently at the edge. Tell us which it is when you send the plans and the quote will be right first time.
A pre-construction barrier goes in while the slab is open. Once the concrete is poured and the frame is up, the same protection costs several times as much and never covers the same ground. On a Castlecrag build this is genuinely a now-or-never detail.
The system does not stop termites existing - it forces them into the open where an inspection will find them. That is why the annual check is part of the system rather than an optional extra.
- We quote fixed, straight from your plans
- Staged installation that fits your build program
- A physical system, a chemical system, or both together
- Durable notice plus certificate, for the certifier
SYSTEMS WE INSTALL
Termite Barrier Systems We Install in Castlecrag
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 termite-resistant physical membrane laid across the prepared ground before the pour, protecting the whole footprint of the slab.
Penetration Collars
Collars sealed to every plumbing pipe, conduit and service that passes through the slab. These are the most common hidden entry points for termites.
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. Add a reticulation network and the barrier can be topped up later without digging anything up.
Suspended Floors & Piers
On a sloping or elevated site, the bearers, piers and suspended timber floor are all protected.
Retaining Walls & Complex Sites
Retaining walls, sandstone excavation, step-downs and cut-and-fill - all common in Sydney, all needing their own detailing.
WHY DURING THE BUILD
Why Install During Construction in Castlecrag
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
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
The installation certificate and durable notice have to reach the certifier before the Occupation Certificate is issued.
Resale Confidence
Having the termite protection documented and compliant reassures buyers, inspectors and lenders alike.

COMPARE SYSTEMS
Physical vs Chemical Termite Barriers in Castlecrag
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 | A physical layer - membrane, stainless mesh or graded stone - that termites cannot get through, beneath the slab or at its edge | Intended to last the life of the slab if not disturbed, and requires no chemical top-up | Slab-on-ground builds, and owners who want to avoid chemicals |
| 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 soil zone formed with termiticide under and around the structure | Label and soil conditions govern how long it lasts; re-application is possible | Cost-conscious builds and certain complex sites |
| Reticulation system | A pipe network put in ahead of paving, letting termiticide be pumped into the soil later | Rechargeable for as long as the building stands, without digging paths up | Homes enclosed by paving or landscaping |
| 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
How a Pre-Construction Barrier Is Installed in Castlecrag
Termite barriers are installed in stages that follow the build, not in a single visit.
01
Plan Review & Fixed Quote
Plans and slab details to us, and you get a system recommendation plus a fixed price stage by stage.
02
Stage 1: Before the Pour
Every service through the slab is collared first, then the under-slab membrane or chemical treatment goes down on the prepared site.
03
Stage 2: Slab Edge & Cavity
While the brickwork or cladding goes up, the perimeter and cavity barriers are installed, leaving no gap at the slab edge.
04
Stage 3: Final Perimeter
A chemical perimeter or reticulation system, where specified, is completed around the building before any paving or 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
At handover the owner is given maintenance advice and the recommended inspection schedule that keeps the system effective.

For Builders, Developers & Owner-Builders
Coordinating with your trades
We work to the plumber's set-out and the concreter's program. Let us know when the services are in and collars are confirmed before the pour inspection.
- Penetration collars fitted before the pour
- The slab edge and cavity barrier installed as the walls rise
- Perimeter done before any paving goes down
Multi-unit and repeat work
Consistent pricing across the project, a single point of contact, and documentation for every lot or dwelling.
Avoiding certification delays
Missing durable notices or unclear installation records are a common reason for occupation certificate delays. We supply everything together so the certifier has what they need.
AFTER HANDOVER
How to Keep Your Termite Barrier Effective in Castlecrag
A barrier only works if it stays intact and visible. Homeowners should follow these points for the life of the building.
- Keep a minimum 75 mm of the slab edge clear as the inspection zone, free of soil, mulch and paving.
- Keep garden beds and stacked timber off the walls
- Keep render and debris out of the weep holes
- Any leak near the house - tap, downpipe, hot water unit - needs fixing
- Tell your builder or installer before drilling through the slab
- Check that new pipes or extensions are protected too
- Book a timber pest inspection at least once every 12 months
- File the durable notice and installation certificate with your property records
PRICING FACTORS
What Affects the Cost of a Termite Barrier in Castlecrag
| Factor | Why it matters |
|---|---|
| Size of slab and perimeter | Larger footprints take more membrane, more perimeter protection and more labour |
| Which system | A full under-slab physical system, a perimeter-only system, and chemical or reticulation options all price differently |
| Number of penetrations | Every plumbing and electrical penetration through the slab requires a collar |
| Complexity of the site | Retaining walls, step-downs, sandstone cuts and suspended floors each add detailing |
| Number of visits | The staged install follows your build program, and multi-dwelling sites can 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 does pre-construction termite barriers cost in Castlecrag?
Barriers are quoted off your plans and slab details. The fixed price depends on the size of the property and how far the problem has spread, and we confirm it before we start - there is no call-out fee in Castlecrag 2068. You get the AS 3660.1 certificate and the durable notice for the meter box.
How soon can someone come out to Castlecrag?
Same-day attendance is usually available. Castlecrag is about 7.6 km north of the CBD in the Lower North Shore, and we give you a firm arrival time rather than an all-day window.
Why are termites such a problem in Castlecrag?
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.
Is Castlecrag mostly houses or units for this sort of work?
Older houses on sloping blocks, many with a lower level cut into the slope - that level is usually where we start.
Can you do a rental or a strata property in Castlecrag?
We do all of those. A good share of the Castlecrag jobs we run are tenanted or strata properties, so the written record comes as standard.
Is it safe for kids and pets?
It is, as long as you follow what we tell you on the day - usually keeping off treated surfaces for a couple of hours. Let us know at booking about young children, pets or an aquarium.
Do we have to go out while you work?
In the great majority of jobs, no. If one area needs to be left for an hour or two we say so before we start rather than after.
How long will the technician be on site?
Allow an hour to two hours for most properties. A bigger building, or one where the problem has spread, takes longer - and we would rather tell you that when quoting than rush it.
Is there a warranty if they return?
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 Castlecrag too?
Yes - we work right across the North Sydney, Mosman, Willoughby, Lane Cove and Hunters Hill area, which takes in Castlecrag and the suburbs around it.
