The Hills District · AS 3660.1
Beaumont Hills was built out through estates such as The Sanctuary and The Outlook from the early 2000s, postcode 2155, and those original termite systems are now old enough that an extension or pool needs its own fresh barrier.
Quick answer
Yes. Beaumont Hills sits within The Hills Shire in a termite-prone part of Sydney, so any new footing or extension needs a compliant termite system, even on a home built in the last twenty years. Many original 2000s-era barriers are ageing. New work has to meet AS 3660.1, with its durable notice and certificate lodged with the certifier.
Termite barriers in Beaumont Hills
Beaumont Hills is a low-density residential suburb in The Hills Shire, about 31 km north-west of the Sydney CBD in postcode 2155. Most of it was built from the early 2000s in estates such as The Sanctuary and The Outlook, so the housing is largely modern brick and rendered family homes, many double-storey, on sloping streets that open up views west towards the Blue Mountains. Beaumont Hills Shopping Centre sits at the heart of the suburb, with metro stations at Kellyville and Rouse Hill a short bus trip away. With the estate now essentially built out, current work is mostly extensions, pools, granny flats and renovations on those existing homes rather than new house-and-land construction, and each of those still needs a compliant termite management system for any new footing or slab.
Being relatively new does not make a Beaumont Hills home pest-proof. A house from the early 2000s has had roughly twenty years for its original termite protection to age, and for owners to add paving, decks and garden beds that can cover a barrier or block the inspection zone it depends on. Beaumont Hills also includes a natural creek reserve and several parks, which bring moisture, shade and insect life right up to back fences on some streets. A new extension or pool footing on one of these established blocks needs its own complete barrier, tied in carefully where it meets the original slab rather than assumed to still be protected by whatever was installed the first time round.

Local conditions
Three things matter most on a Beaumont Hills project, and none of them are about the suburb being new.
Homes built through the early 2000s estate boom have termite systems that are now around two decades old, and chemical soil barriers in particular have a working life that eventually runs out. An extension or renovation is a natural point to install fresh, current-standard protection rather than assume the original system still covers the whole property.
Owners across Beaumont Hills have added paving, decking and garden beds since their homes were built, and those additions can cover the inspection zone a barrier depends on being kept clear. A new extension footing gives us a chance to reset that zone properly around the addition.
The suburb's natural creek reserve and several parks bring moisture, shade and insect life close to back fences on some Beaumont Hills streets. Blocks nearer that reserve need their perimeter detailed with that extra dampness in mind, rather than treated the same as a block well away from any watercourse.
What we install here
Most Beaumont Hills jobs are extensions, pools, granny flats and renovations on the suburb's early-2000s brick and rendered homes, rather than new house-and-land construction on vacant estate land. We fit collars to every new penetration, run the perimeter to tie in with the existing slab edge, and check whether the original barrier is still likely to be effective before recommending whether it needs topping up or replacing. We schedule our visit for once the plumber has finished the rough-in and before the pour, the same as on any new build.
Local knowledge
Beaumont Village sits at the heart of the suburb, and like any shopping centre its bins and food waste can draw rodents that work outward into nearby streets, which is a separate issue from termite risk but one we keep an eye on during inspections. Turkeys Nest Reserve, close by, adds garden beds and leaf litter that shelter insect life near houses on that side of Beaumont Hills. Both landmarks sit close to the suburb's original estate streets, where ageing barriers are the main consideration on any new work.
Beaumont Hills is certified through The Hills Shire, and whatever the size of the addition, the certifier wants a durable notice fixed in the meter box and an installation certificate that lists the products, the protected areas and who installed the system, before granting occupation. This applies to a new extension or granny flat just as much as it did to the original home, and both documents are ready the moment our stage of the job is done.

Systems we install
Every photo below is from one of our own Sydney jobs. We look at your slab design, site and budget, then recommend a system or a combination.
01A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
A termite barrier isn't a single visit. Each part goes in when the site is ready for it, and we fit around your plumber, concreter and bricklayer.
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.
Compare systems
Both can meet AS 3660.1. The best choice depends on your slab type, what surrounds the house and how much ongoing upkeep the owner wants.
Physical protection
Entry-point protection
Soil protection
Top-up protection
Most of the Sydney builds we work on use a combination: physical collars on every penetration plus a physical or chemical perimeter.

Beaumont Hills questions

+61 450 515 215Yes. The original system is now around two decades old and may no longer be fully effective, and any new footing or slab is treated as new construction under the National Construction Code regardless of the house's age. We assess the existing barrier's condition and detail the new work to tie into it properly, with fresh collars and perimeter protection where the extension meets the ground.
It can, if the paving covers the inspection zone the original barrier relies on being kept clear, since that makes early termite activity harder to spot. When we work on an extension or new slab nearby, we look at what has been added since the original build and can advise on resetting a proper inspection zone around the new work.
Blocks closer to the creek reserve and its parks tend to hold more moisture and shade than streets further from it, which suits termite activity more readily. We still install a compliant barrier on every Beaumont Hills job, but on reserve-adjacent blocks we pay closer attention to drainage and run a fuller perimeter around the new footing.
In most cases, yes. The National Construction Code requires a termite management system for new houses and outbuildings in termite-prone areas where the primary building elements can be damaged by termites. Sydney is termite-prone, so the system is installed to AS 3660.1 and your certifier asks for the installation certificate and durable notice before the Occupation Certificate is issued.
It depends on slab area, perimeter length, the number of pipe penetrations, the system chosen, site complexity and how many visits the build needs. Send us the plans and we return one fixed written quote covering every stage. Quoting is free.
