What we need to quote
We need the architectural or slab plan, the slab type (raft, waffle pod, suspended), the address, a rough pour date, and engineering details for retaining walls or step-downs.
Pre-Construction Termite Barriers in North Curl Curl 2099 — local technicians, fixed prices and a written report. Barriers are quoted off your plans and slab details.
Real, verified feedback from people we've helped — straight from Google.
Where North Curl Curl sits, who covers it and what it costs.
North Curl Curl is part of the Northern Beaches, 14.2 km or so north-east of the GPO, and 2099 is a postcode we know well. We run North Curl Curl on a regular route, and same-day attendance is usually available.
A lot of our North Curl Curl jobs are in the streets around Dee Why Grand Shopping Centre and Flora and Ritchie Roberts Reserve, and we are out near Harbord Bowling and Recreation Club regularly enough that the technician usually knows the access before they arrive.
Under Northern Beaches, we cover North Curl Curl and Curl Curl, Freshwater and Dee Why alike. Being this close to the coast, sub-floors and ground-floor bathrooms stay damp most of the year, which is the condition that keeps activity going.
North Curl Curl jobs tend to be ground-floor units with a damp sub-floor, and houses where the garage sits below the living level. Let us know which when you ring and we will plan the visit around it.
Beyond that we are regularly around Pavilion Reserve, and out as far as Curl Curl Beach. If you are anywhere in 2099, you are inside the area we run.
We confirm your slot the day before and arrive at a stated time. Curl Curl and Freshwater sit on the same run, so earlier appointments in 2099 come up regularly.
It is not guidance. It is the benchmark a private certifier assesses against, which is why we install to the approved plan rather than to habit.
Retro-fitting means drilling and injecting a finished slab, working around landscaping and services. It is slower, more expensive and less complete than doing it at construction on a North Curl Curl block.
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.
Photos from our own Sydney installations, not stock images. We recommend the right mix for your slab design, site and budget.

Before the pour, a termite-resistant membrane goes across the prepared ground, protecting the full slab footprint.

Every pipe, conduit and service through the slab gets a collar sealed to it - these penetrations are the commonest concealed way in.

Slab edge and wall cavity are both barriered, blocking the concealed tunnels termites otherwise build up the outside.

APVMA-registered termiticide applied to the soil. Add a reticulation network and the barrier can be topped up later without digging anything up.

Protection for bearers, piers and suspended timber floors on sloping or elevated sites.

Detailed work against retaining walls, sandstone cuts, step-downs and the cut-and-fill sites common around Sydney.
Once the slab is poured, the areas termites use most are sealed away for good.
Installing at construction costs a fraction of retrofitting a system, let alone repairing termite damage later.
If a new Class 1 home or Class 10 outbuilding has termite-susceptible primary building elements, a compliant system is required.
Once concrete covers them, pipe penetrations and slab joints cannot be fully protected - it has to happen before the pour.
An under-slab system protects the parts of the footprint no later treatment can access.
The installation certificate and durable notice have to reach the certifier before the Occupation Certificate is issued.
Buyers, building inspectors and lenders all take comfort from documented, compliant termite protection.
One call to a licensed Sydney technician gets you straight advice and a fixed quote within 30 minutes.
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-proof layer of sheet, stainless mesh or graded stone, installed under the slab or around the perimeter | Designed for the life of the slab if undisturbed; no chemical recharge required | Slab-on-ground construction and owners preferring no 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 | Pipework laid before the paving so termiticide can be pumped back into the soil later | Rechargeable for the life of the building, with no need to lift paths | Houses ringed by paving or landscaping |
| Baiting (post-construction) | In-ground stations that monitor and then eliminate the colony | The stations require servicing on a regular schedule | Existing homes - see termite control |
Termite barriers are installed in stages that follow the build, not in a single visit.
Send through the plans and the slab details and you get back a recommended system with a fixed price against every stage.
Penetration collars to all services first, then the under-slab membrane or chemical treatment once the site is ready.
Perimeter and cavity barriers go in as the brickwork or cladding rises, so the slab edge is never left with a gap.
Where the design calls for it, the chemical perimeter or reticulation is completed around the finished building ahead of paving and landscaping.
The system is recorded on a durable notice fixed in the meter box, and the installation certificate goes to the builder and the certifier.
The owner receives maintenance advice and a recommended inspection schedule to keep the system effective.
| Document | What it is | Who needs it |
|---|---|---|
| Durable notice | The permanent meter-box notice recording the system, the install date, any chemical's life expectancy, the installer and inspection advice | The certifier, the owner, and owners after them |
| Installation certificate | A written record of the system and products installed, which areas are protected, and the installer's licence number | The builder, the certifier and the owner's file |
| Product information | Information on the physical system or termiticide applied, including chemical safety data sheets | The builder and the owner |
| Maintenance & inspection advice | Maintenance guidance and the AS 3660.2 recommended inspection frequency | Homeowner |
We need the architectural or slab plan, the slab type (raft, waffle pod, suspended), the address, a rough pour date, and engineering details for retaining walls or step-downs.
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.
We give developers and volume builders consistent pricing, one contact, and documentation lot by lot.
Delays at occupation certificate stage usually come down to a missing durable notice or unclear records. We provide the complete set at once.
A barrier only works if it stays intact and visible. Homeowners should follow these points for the life of the building.
| Factor | Why it matters |
|---|---|
| Slab area & perimeter length | Larger footprints need 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 | A collar is needed for each plumbing and electrical penetration through the slab |
| How complex the site is | Retaining walls, step-downs, sandstone excavation and suspended floors all add detailing |
| Number of visits | The staged install follows your build program, and multi-dwelling sites can be combined |

Pre-purchase inspections ask about the system and the notice. Having both in order removes a negotiating point from the buyer's side.
Anywhere in North Curl Curl is within the area we attend for pre-construction work, including sites the larger operators will not travel to.
The assumption that a new build is low risk is backwards. New construction on previously vegetated land is exactly where we see early activity.
Licence 5122967 in NSW, and installations completed to AS 3660.1.
We work to your builder's program, so a barrier stage never holds up a pour.
We supply the durable notice, the installation certificate and the product details.
Single homes, granny flats, duplexes and multi-unit developments alike.

Get a Free QuoteBarriers are quoted off your plans and slab details. We quote on the property rather than the postcode, so a unit in North Curl Curl 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.
Same-day attendance is usually available. Our Northern Beaches technicians cover North Curl Curl daily, and you get a confirmed arrival time when you book.
Being near the water means humidity that never really drops. Sub-floors stay moist, lower levels stay cool and damp, and termites do well in both.
Units close to the water, houses further back, and sub-floors that hold moisture in both.
We do. A lot of our North Curl Curl work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
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.
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.
An hour to two hours covers most jobs. The size of the building and the extent of the problem are what change it.
You get the AS 3660.1 certificate and the durable notice for the meter box. A return visit inside that period does not cost you anything.
Yes - we work right across the Northern Beaches area, which takes in North Curl Curl and the suburbs around it.
