You move into your new home, everything looks perfect, and for the first few years, life feels secure. Then, just as the builder’s warranty is about to expire, hidden termite damage is discovered inside wall framing, floor joists, or skirting boards. Many Australian homeowners assume that a new build automatically includes strong termite control, but that assumption is proving costly.
Termites remain one of the most destructive pests in Australia. Without ongoing monitoring and professional termite control strategies, even recently constructed homes can become vulnerable within just a few years.
Why New Builds Are Not Automatically Protected
New homes must comply with the Building Code of Australia and Australian Standard AS 3660.1, which requires a termite management system. However, compliance does not guarantee comprehensive protection.
Builders may install a chemical soil treatment or a physical barrier such as metal ant caps or treated timber. While these systems form the foundation of termite control during construction, their long-term performance depends heavily on correct installation and ongoing maintenance.
Cheaper chemical treatments may degrade sooner than expected. Physical barriers can be disrupted during landscaping or later building modifications. Without regular inspections, homeowners often remain unaware that their termite control system has been compromised.
How Construction Practices Create Termite Entry Points
Even well-built homes can develop vulnerabilities. Termites can pass through gaps as small as one millimetre. Plumbing penetrations, electrical conduits, drainage systems, and slab joints all create potential entry points if not properly sealed.
Landscaping installed after construction often unintentionally bridges termite barriers. Garden beds, paving, turf, or mulch placed too close to the slab edge can allow termites to bypass protective zones.
Cracks from slab settling or inadequate exposure of slab edges also create hidden access routes. Without ongoing termite control monitoring, these weaknesses can remain undetected for years while termites establish colonies inside structural timber.
The Insurance Reality Most Homeowners Discover Too Late
One of the harshest realities for new homeowners is that standard insurance policies generally do not cover termite damage. Insurers classify termite destruction as a maintenance issue rather than an unforeseen event.
Builder warranties cover structural defects, not pest infestation. If termite damage appears after the warranty period, repair costs fall entirely on the homeowner. Structural repairs frequently run into tens of thousands of dollars.
This is why independent termite control inspections are essential, even for new homes that appear protected.
Why the First Five Years Demand Active Termite Control
The first five years after construction are critical. Chemical soil barriers begin to lose effectiveness over time. Even high-quality treatments require periodic inspection and potential retreatment.
Physical systems such as stainless-steel mesh or graded stone barriers are durable but not immune to disturbance. Landscaping changes, renovations, or soil movement can weaken protection.
Termites forage continuously. Colonies may extend dozens of metres underground. Once they detect a vulnerability in the termite control system, they can enter and begin feeding long before visible signs appear.
Regular inspections by licensed professionals significantly increase the likelihood of early detection. Effective termite control during this early period protects framing, subfloors, and structural supports before irreversible damage occurs.
What Every New Homeowner Should Do Within the First Year
The safest approach is to commission an independent termite inspection within the first year of ownership. Do not rely solely on builder documentation. A licensed professional can confirm:
- What termite management system was installed
- Its expected lifespan
- Whether landscaping has compromised barrier zones
- Whether additional termite control measures are required
Homeowners should also review the termite management notice affixed near the meter box, which outlines the protection system and inspection requirements.
Establishing an annual termite control schedule aligned with Australian Standard AS 3660.2 ensures that the protection remains effective.
In addition, avoid placing mulch, soil, timber, or garden beds against foundation walls. Maintain adequate slab edge exposure and ensure drainage directs water away from the structure, as moisture attracts termite activity.
The Financial and Structural Risk of Waiting
Termites operate silently. By the time visible damage appears, structural timber may already be extensively hollowed. Repairs often involve removing wall linings, replacing framing, and restoring flooring systems.
Proactive termite control costs a fraction of structural repair. Early detection prevents extensive damage and preserves property value.
New construction does not eliminate risk. It only reduces it temporarily if maintenance is ignored.
Conclusion
A new home is not automatically termite-proof. Minimum building compliance does not guarantee lasting protection. Chemical barriers deteriorate, landscaping alters protection zones, and construction penetrations create vulnerabilities.
Ongoing termite control through annual inspections and professional monitoring is the most reliable way to protect your investment. Waiting for visible signs is not a strategy — it is a risk.
Taking proactive steps within the first five years significantly reduces the chance of major structural damage and unexpected repair costs.
FAQs
Why do new homes still get termites?
Because building compliance does not guarantee permanent termite control, and barriers can degrade or be breached over time.
Is termite damage covered by insurance in Australia?
Most standard policies do not cover termite damage, as it is considered preventable through maintenance.
How often should termite control inspections be conducted?
Annual inspections are recommended, with more frequent checks in high-risk areas.
What is the most effective termite protection for new builds?
A combination of physical barriers, chemical treatments, and ongoing termite control inspections provides the strongest defence.
Can landscaping affect termite protection?
Yes. Soil, mulch, and garden beds placed near foundation walls can compromise barrier systems and reduce termite control effectiveness.
