SERVICING MOUNT COLAH
Pre-Construction Termite Barriers Across Mount Colah
What we cover in Mount Colah, and how quickly we can get there.
Postcode 2079 covers Mount Colah and the streets immediately around it. At about 23.3 km north of the CBD it falls in the Upper North Shore, where we have vans out daily. We run Mount Colah on a regular route, and same-day attendance is usually available.
The Mount Colah addresses we attend cluster around Mount Colah station and Hunt Reserve. Asquith Golf Club is another part of the suburb we are called to often.
Under Ku-ring-gai and Hornsby, we cover Mount Colah and Mount Kuring-gai, Hornsby Heights and Asquith alike. Backing onto bush means re-entry is the issue, so proofing and the perimeter do the real work here.
The bulk of our Mount Colah work is homes on sloping blocks with a sub-floor and bush on the boundary. Mention the detail when you call 1300 313 373 - it decides how long we need on site.
All of 2079 falls inside the area we service.
We confirm your slot the day before and arrive at a stated time. Mount Kuring-gai and Hornsby Heights sit on the same run, so earlier appointments in 2079 come up regularly.

OVERVIEW
Pre-Construction Termite Barriers Done Right the First Time
A barrier is only as good as its weakest penetration. One untreated conduit gives a colony a clean route into the frame.
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 Mount Colah build this is genuinely a now-or-never detail.
Most Mount Colah 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.
- We quote fixed, straight from your plans
- Installation staged around your build program
- Physical, chemical and combination systems
- Durable notice plus certificate, for the certifier
SYSTEMS WE INSTALL
Termite Barrier Systems We Install in Mount Colah
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
Laid on the prepared ground before the pour, this termite-resistant membrane protects the complete footprint of the slab.
Penetration Collars
Every pipe, conduit and service through the slab gets a collar sealed to it - these penetrations are the commonest concealed way in.
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
An APVMA-registered termiticide into the soil, optionally with a reticulation pipe network so it can be recharged later without excavation.
Suspended Floors & Piers
Sloping and elevated blocks get their piers, bearers and suspended timber floors protected.
Retaining Walls & Complex Sites
Retaining walls, sandstone cuts, step-downs and cut-and-fill sites are detailed individually - all of them common here.
WHY DURING THE BUILD
Why Install During Construction in Mount Colah
Once the slab is poured, the areas termites use most are sealed away for good.
A Fraction of the Cost
A pre-construction barrier costs far less than a retrofitted system or repairs to termite damage later.
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
Full protection of pipe penetrations and slab joints is possible only before the concrete is poured over them.
Whole-Footprint Protection
An under-slab system covers ground that nothing applied after construction can get to.
No Occupation Certificate Delays
Your certifier needs the installation certificate and durable notice before issuing the Occupation Certificate.
Resale Confidence
Documented, compliant termite protection reassures buyers, building inspectors and lenders.

COMPARE SYSTEMS
Physical vs Chemical Termite Barriers in Mount Colah
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 termite-resistant layer (sheet, stainless mesh or graded stone particles) that termites can't chew through, laid under the slab or at the perimeter | Designed to last as long as the slab if it isn't disturbed. No chemical top-ups. | Slab-on-ground homes and owners who want a non-chemical option |
| Penetration collars | Collars physically sealed to every pipe and conduit through the slab | Long-lived where installation before the pour is done properly | Every slab, and typically with a perimeter system as well |
| Chemical soil barrier | A treated zone of termiticide in the soil under and around the building | Service life depends on the product label and soil conditions. It can be re-applied. | Budget-conscious builds and some complex sites |
| Reticulation system | Pipework laid before paving, allowing termiticide to be pumped into the soil later | Can be recharged for the life of the building without lifting paths | Houses surrounded by paving or heavy 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 Mount Colah
Termite barriers are installed in stages that follow the build, not in a single visit.
01
Plan Review & Fixed Quote
Give us the plans and slab details; back comes a recommended system and a fixed price for every stage.
02
Stage 1: Before the Pour
Collars are fitted to all service penetrations, and the under-slab membrane or chemical treatment follows 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
Where specified, a chemical perimeter or reticulation system is completed around the finished building before paving and landscaping.
05
Durable Notice & Certificate
A durable notice goes into the meter box to record the system, with the installation certificate to the builder and certifier.
06
Handover Advice
Handover includes maintenance advice and the recommended inspection schedule for keeping the system effective.

FOR BUILDERS
For Builders, Developers & Owner-Builders
Coordinating with your trades
We schedule around the plumber's set-out and the concreter's pour. Tell us when services are in and we will confirm the collar installation before the pour inspection.
- Penetration collars fitted before the pour
- The slab edge and cavity barrier installed as the walls rise
- The perimeter is completed prior to paving
Multi-unit and repeat work
Developers and volume builders work to consistent pricing with a single contact and documentation for every 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 Mount Colah
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.
- Don't construct garden beds or stack timber against the building
- Weep holes need to stay open, with no render or debris blocking them
- Repair leaking taps, downpipes and hot water units near the building
- Before drilling through the slab, tell the builder or the installer
- Any new pipes or extensions should be protected as well
- Book a timber pest inspection at least 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 Mount Colah
| Factor | Why it matters |
|---|---|
| Footprint and perimeter | More area means more membrane, more perimeter protection and more time on site |
| System type | Full under-slab physical, perimeter-only, and chemical or reticulation systems are priced differently |
| Service penetrations | Every plumbing and electrical penetration through the slab has to be collared |
| Difficulty of the site | Retaining walls, step-downs, sandstone excavation and suspended floors add to the detailing |
| Visits to site | Staged installation tracks the build program, with multi-dwelling sites often combined |

Our barrier work takes in Mount Colah and across toward Mount Kuring-gai, on single builds and multi-lot developments alike.
A documented, serviced termite management system is something a Mount Colah buyer's pest inspector will note favourably. The absence of paperwork is something they will note the other way.
A barrier is a continuous system, so it fails at the join. On Mount Colah sites the usual culprits are a penetration added after our visit and a section of slab edge covered before anyone inspected it.

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 QuoteHow much does pre-construction termite barriers cost in Mount Colah?
Barriers are quoted off your plans and slab details. We quote on the property rather than the postcode, so a unit in Mount Colah and a large house are priced differently. The figure is fixed before any work starts. You get the AS 3660.1 certificate and the durable notice for the meter box.
How quickly can you get to Mount Colah?
Same-day attendance is usually available. We are about 23.3 km north of the city here, and Mount Colah is covered by the Upper North Shore team.
What makes Mount Colah prone to termites?
Backing onto bush means constant pressure from outside. termites are already established in the reserve, and the house is simply the next thing they reach.
Is Mount Colah mostly houses or units for this sort of work?
Mostly detached housing backing onto reserve. Proofing and the perimeter are what actually hold here.
Do you work with agents and strata managers in Mount Colah?
Yes. Houses, townhouses, units, strata common property, rentals and commercial sites in Mount Colah 2079 are all part of what we do, and the paperwork is the kind agents accept.
Is the treatment safe around children 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?
In most cases you can stay. Where an area does need to be left clear it is for a couple of hours at most, and we say so before we start.
How much time should I allow?
Typically one to two hours on site. What extends it is size, access and how far the problem has gone, all of which are accounted for in the quote.
What happens if it is not fixed?
You get the AS 3660.1 certificate and the durable notice for the meter box. So if they turn up again within the warranty, ring us and we will attend.
Do you cover the suburbs around Mount Colah too?
Yes. As well as Mount Colah we cover Mount Kuring-gai, Hornsby Heights, Asquith and North Wahroonga on the same runs, so a job that crosses a boundary can be handled in one visit.
