What we cover in North St Ives, and how quickly we can get there.
North St Ives is part of the Upper North Shore, 16.8 km or so north of the GPO, and 2075 is a postcode we know well. We run North St Ives on a regular route, and same-day attendance is usually available.
The North St Ives addresses we attend cluster around Pymble Golf Club and St Ives Shopping Village. Hassall Park is another part of the suburb we are called to often.
This is the Ku-ring-gai and Hornsby area, and our runs here also take in St Ives, St Ives Chase and North Turramurra. Bush edges keep re-supplying the problem, which is why we treat the boundary rather than only the interior.
What we see in North St Ives is properties where the fence line matters as much as the kitchen. Describing it accurately when you book saves a second visit.
Beyond that we are regularly around St Ives Memorial Park, and out as far as Dalrymple-Hay Nature Reserve. If you are anywhere in 2075, you are inside the area we run.
The 2075 run is set the day before and you are given an arrival time. Where St Ives and St Ives Chase fall on the same round, we can usually bring the visit forward.
Tell whoever does the landscaping on your North St Ives build to keep soil, mulch and paving below the slab edge. It is the single most common way a good system is quietly defeated.
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.
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 St Ives block.

A sheet membrane that termites cannot pass, laid across the prepared ground before the pour so the entire footprint is covered.

Collars are sealed to every plumbing and electrical penetration through the slab, the most frequent concealed entry route there is.

A physical barrier around the slab edge and into the wall cavity, which stops termites building concealed tunnels up the outside of the slab.

APVMA-registered termiticide applied to the soil, with the option of a reticulation pipe network so the barrier can be recharged later without digging.

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

Retaining walls, sandstone cuts, step-downs and cut-and-fill sites are detailed individually - all of them common here.
Once the slab is poured, the areas termites use most are sealed away for good.
Compared with a retrofit - or with repairing damage - a pre-construction barrier is a small cost.
New homes (Class 1) and outbuildings (Class 10) with termite-susceptible primary building elements need a compliant termite management system.
Before the pour is the only opportunity to fully protect the pipe penetrations and slab joints.
Areas no post-construction treatment can ever reach are covered by an under-slab system.
No Occupation Certificate is issued without the installation certificate and durable notice going to the certifier.
Buyers, inspectors and lenders all respond to documented, compliant termite protection.
A licensed Sydney technician will talk it through and give you a fixed quote within half an hour.
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, stainless mesh or graded stone creating a layer termites cannot chew through, under the slab or at the perimeter | As durable as the slab itself when left undisturbed, with no top-ups needed | Slab-on-ground homes and non-chemical preferences |
| Penetration collars | Collars sealed physically to every pipe and conduit through the slab | Durable when fitted correctly ahead of the pour | All slabs, normally combined 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 | 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 used for monitoring and then baiting out the colony | Regular servicing of each station is required | For existing homes, see termite control |
Termite barriers are installed in stages that follow the build, not in a single visit.
Send us your plans and slab details. We recommend a system and give you a fixed price for every stage.
Penetration collars fitted to all services, and an under-slab membrane or chemical treatment installed once the site is prepared.
Perimeter and cavity barriers installed as the walls go up, so no gap is left at the slab edge.
Where specified, we complete the chemical perimeter or reticulation around the finished building, before paving and landscaping.
The system is documented on a durable notice in the meter box, and the installation certificate goes to builder and 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 | Fixed permanently in the meter box, recording the system, install date, chemical life expectancy, installer and inspection advice | Certifier, current owner and future owners |
| Installation certificate | Written confirmation covering the system and products used, the protected areas and the installer's licence | Builder, certifier, and the owner's own records |
| Product information | The details of whichever physical system or termiticide was used, with safety data sheets for any chemical | Builder and owner |
| Maintenance & inspection advice | Guidance on keeping the barrier effective, with the AS 3660.2 recommended inspection frequency | Homeowner |
The architectural or slab plan, which slab type it is - raft, waffle pod, suspended - the site address, approximate pour date, and any retaining wall or step-down engineering.
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.
Developers and volume builders get consistent pricing, a single point of contact and documentation for every lot or dwelling.
The common cause of occupation certificate delay is a missing durable notice or unclear records - so we supply everything together.
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 | The bigger the footprint, the more membrane, perimeter protection and labour required |
| Which system | A full under-slab physical system, a perimeter-only system, and chemical or reticulation options all price differently |
| Service penetrations | Every plumbing and electrical penetration through the slab has to be collared |
| Site complexity | Extra detailing comes with retaining walls, step-downs, sandstone excavation and suspended floors |
| Number of visits | The staged install follows your build program, and multi-dwelling sites can be combined |

Clay soils also hold moisture against the slab, which is the condition termites want. The barrier matters more on those blocks, not less.
An addition to a protected house is a new entry point unless it is tied into the existing system. We treat it as part of the whole, not a separate job.
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.
Licence 5122967 in NSW, and installations completed to AS 3660.1.
Our scheduling follows the builder's program - a barrier stage will not hold up your pour.
Everything the certifier wants: durable notice, installation certificate, product details.
Single dwellings and granny flats through to duplexes and multi-unit developments.

You get that number up front for North St Ives 2075, with no call-out fee. You get the AS 3660.1 certificate and the durable notice for the meter box.
Same-day attendance is usually available. North St Ives is about 16.8 km north of the CBD in the Upper North Shore, and we give you a firm arrival time rather than an all-day window.
Undisturbed ground, leaf litter and fallen timber right to the boundary mean termites are always established next to the house. Re-entry, not eradication, is what we are managing here.
Homes with sub-floors, roof voids and bush at the boundary - all three get inspected.
Yes. We work in houses, units, strata blocks, rentals and commercial premises across North St Ives 2075, and we provide the written report agents and strata managers ask for.
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.
Between one and two hours covers the majority of jobs. We do not book so tightly that a technician has to cut a job short.
You get the AS 3660.1 certificate and the durable notice for the meter box. A return visit within the warranty period costs you nothing.
Yes - we work right across the Ku-ring-gai and Hornsby area, which takes in North St Ives and the suburbs around it.
