Physical & Chemical Termite Prevention Barriers — Sunshine Coast to North Brisbane

Wondering how you can protect your home from termites? Termite barriers are the only thing you can have to protect your home from termites by reducing the likelihood of damage.

Did you know that 1 in 4 homes are attacked by termites each year? This is why every home in Australia should have a Termite Management System in place and maintained around their home.

Our family run business has been protecting homes from termites on the Sunshine Coast for more than 30+ years and we’ve recently added this service to the North Brisbane area. You can be sure our family will be here to protect your family from termites far into the future.

We only use the best products on the market for termite prevention via physical barriers and chemical soil treatments: Termidor or Termidor HE. Our long history of experience has enabled us to install the highest quality barriers with interest and fee-free payment plans to families like yours.

Our termite prevention treatments can be split into three categories:

  1. Physical Termite Prevention Barriers
  2. Chemical Termite Prevention Barriers
  3. Termite Baiting (not our preferred prevention method)

What is a physical termite barrier?

A physical termite prevention barrier is exactly that, a physical barrier that is installed around the perimeter of your home to block any entrance termites may find. A physical termite prevention barrier can only be installed before a home is constructed.

A physical termite barrier involves installing a termiticide impregnated polymer sheet (which is a plastic sheet) around the concrete slab edge, brick cavity perimeter or concrete slab cold joints of a building and putting collars (plastic mouldings) around service penetrations (where plumbing and electrical hookups come into the building).

Our team installs physical prevention barriers for both new home builds and home renovations and extensions. All you need for a proposal is to send us your building plans. Once everyone is happy with the proposed termite management system we’ll work directly with the builder to schedule different stages of installation.

For physical prevention barriers to be successful we always recommend contacting us early in the plans. Far too often we get a phone call the night before the concrete slab is poured, meaning we are unable to help on such short notice, or other vital steps have been missed. It is important to contact us at least a few weeks prior to laying your foundation.

What is a chemical termite barrier?

A chemical termite prevention barrier involves exactly that, chemicals that are applied to the soil around the perimeter of your home’s foundation to prevent termites.

Chemical soil prevention treatments can be done either pre or post-construction. This is often the best option and the most forgiving of a home’s construction limitations. Installing chemical soil barriers can involve a mixture of trenching, drilling, installing or refilling reticulation lines, scarifying or horizontal treatments. The end result is that the soil that comes in contact with your home is impregnated with a termiticide. Since barrier installation is labour intensive, and the method of installation is dependant on how your home is built, we come to your home for a free on-site consultation and then provide a free proposal for your review before scheduling the installation.

However, chemical soil barriers are not permanent and have to be topped up, refilled, or reinstalled every so often.

How often should I refill my chemical termite prevention barrier?

The frequency or chemical soil barrier refills depends on three things:

  • The termite pressure in the location
  • The construction of the home
  • The type of soil

For example, a reasonable refill frequency for a standard home in Southeast QLD is once every five years. If you’re unsure about your chemical barrier’s refill rate, contact our team — we’re always happy to help!

What is termite baiting?

In addition to physical termite barriers and chemical termite barriers, there is a third option that’s gained popularity: termite baiting. However, due to the termite pressure we receive in QLD, termite baiting should only be used where a chemical soil barrier is not viable, or as a complementary one.

The only time we will install a baiting system is in the rare circumstance when a building’s design makes this the only option. We care too much about you, your family and your home to use a baiting system when a chemical soil barrier is possible. Your peace of mind, comfort, and the value of your investment is too important for us to consider taking a shortcut. To put it simply, the best option is a chemical soil barrier so that is what we focus on to protect families and their homes.

How much does a termite barrier cost?

A termite barrier can cost anywhere from $220 up to $5000+. It really depends on the scope of work.

Cost Of A Physical Termite Barrier

The cost of a physical termite barrier is dependent on the type of construction and size of the project. Therefore, physical barrier installation can range from a single penetration in a tiny renovation or protecting a single cold joint, to protecting an entire home extension. If you’re curious how much a physical termite barrier will cost for your home, give us a call and we’ll be happy to help!

Physical termite protection is generally used because it’s cheaper than a chemical termite barrier to install and it can last longer (newly installed barriers are warranted for 50 years by the manufacturer). However chemical termite barriers are generally considered superior in performance, but they can cost more and have to be replenished generally every 5 years.

Cost Of A Chemical Termite Barrier

The cost of a chemical termite barrier for a typical 4 bedroom home built on a single level concrete slab can take anywhere between 1-2 days to install and will cost in the range of $1200-$4000.

It’s standard in Australia to need 12 monthly inspections every year in order to maintain the warranty provided by the chemical supplier. Regular treatments are also required to maintain a building warranty for a newly constructed home — these are usually guaranteed for 10 years.

We provide 2 – 12 month interest-free, fee-free payment plans for Termite Management System Installations.

Our Termite Barrier Installation Process

Whether you’re building a new home, needing to refill your existing chemical termite prevention barrier, or have seen termites in and around your home we want you to know exactly what to expect when working with our team!

Free On Site Consultation

We provide a free consultation where one of our pest technicians comes to your home to measure the perimeter of your home, review footing depth, and assess the best way to install a new barrier or rejuvenate an existing one. We will discuss all options with you and develop a plan on how to get the job done right!

Termite Management System Proposal

After our free onsite consultation, you’ll be emailed a Termite Management System Proposal which outlines the scope of work and costs. Our amazing customer service team will be in contact to discuss and answer any questions you may have. We understand this is a big investment and want you to feel 100% prepared with all the information you need!


If you choose our team to help install or replenish a termite prevention barrier for your home, we will send a document to be signed electronically (very easy — we promise!) to confirm a start date. Please note, we take a 20% deposit and book in a time to conduct the installation.

Termite Barrier Installation Or Refill Begins!

Our team will get started on our agreed upon start date and at the end of the installation (or refill) a notice will be placed in your metre box. The specifics of what happens on installation or refill day is dependent on what needs to be done. It can take anywhere from one hour to two days, which can be split across four days. Our team will let you know our plan for your home before installation or refill begins.

Certificate Of Barrier Installation

Our team will email you your certificate of installation for your records. This certificate includes what product was used, how much of it was used, what the active chemical is, how long the system is designed to last, what (if any) limitations there are, and shows where it was installed. This is an important record to keep for the following reasons:

  • Resale of your home
  • If you decide to use a different pest control company in the future, the new company will be able to understand your Termite Management System
  • It tells you when you need to renew your system. In the case of a physical barrier, it shows when you will need to install a chemical soil barrier as you are unable to renew/replenish a physical barrier

Chemical Termite Barriers Vs Physical Termite Barriers

The cost of a chemical termite barrier is the biggest difference and concern for homeowners in comparison to having a physical termite barrier installed. However, since a chemical termite barrier provides more guaranteed protection, it can save you more money in the long run by avoiding unnecessary termite damage if there are any issues with a physical termite barrier.

We’ve included the following pros and cons of each type of termite barrier below:

The Pros & Cons Of A Physical Termite Barrier

The pros of a physical termite barrier include:

  • They’re less expensive than a chemical termite barrier.
  • They last a long time!

The cons of a physical termite barrier include:

  • When a pest company installs a physical termite barrier, they are first on site after the slab is poured and they have no control over the integrity of that system once installed. We’ve often heard of other tradies damaging it, and we’ve even seen it ripped out and thrown in the bin.
  • There is no way of inspecting the physical barrier after your home is built to ensure the physical barrier is intact.
  • It can be bridged or breached; meaning termites can build ways around it.
  • Flaws in your home’s construction can offer entry points around the physical barrier, whereas a chemical soil barrier is much more forgiving.
  • Physical barriers won’t transfer the product to other termites and take out the colony.

The Pros & Cons Of A Chemical Termite Barrier

The pros of a chemical termite barrier include:

  • A chemical termite barrier is the only way to insure your home against termite damage.
  • A chemical termite barrier is the best way to protect your home against termite damage
  • A chemical termite barrier is great value when you consider cost verse the potential damage it can save you.
  • Chemical termite barriers offer residual termite colony control for 5 years.
  • Chemical termite barriers use a transferring effect that is unique to chemical soil barriers.

The cons of a chemical termite barrier include:

  • You have to refill your chemical termite barrier every 5 years.
  • It can be a bit noisy to install, and a bit disruptive around your home during installation.
  • It’s an expense many people don’t budget for.

Frequently Asked Questions About Termite Barriers

What are my options for managing the risk of termites?

Level 1 – No protection, Early Detection – 6 monthly Termite Inspections

Usually the cost of the extra Termite Inspection each year would pay for the barrier. Any potential savings you may make by not installing a chemical soil barrier would be lost in the event your home gets attacked by termites. The cost of treatment and rectification work would be far more costly than the cost of level 3 protection.

Level 2 – Low Protection – Physical Barrier + Annual Inspections

Level 3 – High Protection – Chemical Soil Barrier + Annual Inspections

Residual colony control for 5 years + early detection that may arise from building defects etc. Your home is secure

Level 4 – Ultimate Protection – Chemical + Physical + Annual Inspections

Physical termite barriers built into your home are backed up by chemical soil barriers to further reduce the risk of termites bridging and breaching the physical barrier. Annual inspections further ensure termites don’t find a way to exploit hidden building defects and maintain the physical and chemical manufacturers’ warranties.

How long after a termite barrier is installed will I see the results?

The purpose of a termite barrier is to reduce the likelihood of termites ever entering your home. The result is your peace of mind.

Annual termite inspections will still be required to make sure the barrier remains effective and is not being bridged or breached. Annual inspections coupled with a termite barrier are the best way to reduce the overall risk of termites to your home.
