What Happens During A Pre-Purchase Timber Pest Inspection?

2 July 2025

When you’re putting everything on the line for your dream home or next investment property, the last thing you want is an unwelcome surprise after settlement. Pests like termites, borers or rodents can cause extensive damage before they’re ever detected, with some issues costing thousands to fix. A pre-purchase timber pest inspection can protect you from these hidden dangers, arming you with the knowledge to buy confidently.

This guide explains how a pre-purchase timber pest inspection works in Australia, what you can expect it to cover, the costs involved, and why booking one should be a non-negotiable step in your purchasing process.

Why a Pre-Purchase Timber Pest Inspection Is Essential

Purchasing a house is a significant investment. We understand that you want every assurance your new property is as secure as it seems. While that fresh coat of paint and tidy garden might suggest a well-maintained home, pest issues can lie hidden beneath the surface.

A pre-purchase timber pest inspection gives you a true picture of the property’s condition, highlighting evidence of past or active infestations. Having this professional insight prior to negotiating helps you safeguard your investment and avoid costly surprises down the track.

What Does a Pre-Purchase Timber Pest Inspection Involve?

A professional inspector thoroughly examines all accessible areas of the property, inside and out. The goal: identify evidence of current or past pest activity and assess conditions that could lead to future problems.

You can expect your inspection to include:

A visual assessment of the house and immediate grounds, including roof voids, sub-floor areas, fences, gardens, and outbuildings.
Identification of timber pests: Most commonly, termites, but also borers and fungal decay.
Checking for other pests: Some inspectors also look for evidence of rodents, cockroaches, and other common household pests.
Detailed moisture checks: Areas with excess moisture are more likely to attract termites or lead to structural decay.
A written report: This outlines any evidence found, risk factors, existing damage, and recommendations for treatment or further action.

When you book a pre purchase inspection, you’re investing in your peace of mind. No buyer wants to discover termite activity after getting the keys.

What Should the Inspection Cover?

A comprehensive building pest inspection should address:

All accessible areas such as the interior, exterior, roof space, sub-floors, garages, sheds, and fences within 30 metres of the main building.
Signs of timber pests: Damage caused by termites, borers, and fungal decay (rot).
Conditions conducive to infestation: Leaking pipes, wood-to-ground contact, poor ventilation, and debris around foundations.
Visible damage: Any structural timber that has been affected by pests.
Recommendations for pest control or remedial works.

A good report will clearly distinguish between what has been inspected and any inaccessible or high-risk areas that need special attention.

What Should Pre-Purchase Timber Pest Inspection Cost?

In Australia, the price varies depending on the property size, location, and the extent of the inspection. On average, you can expect to pay between $300 and $600 for a pre-purchase timber pest inspection.

While this might seem like an added expense, it’s a fraction of the cost to repair damage from concealed infestations. If you discover major issues, you might use this information to negotiate with the vendor, or choose towalk away from a risky purchase.

Can You Claim a Pre-Purchase Timber and Pest Inspection?

For most residential buyers, building and pest inspections are not tax deductible. However, inspections may be deductible if you’re buying an investment property or for business purposes, since they can form part of your acquisition costs. We recommend consulting your accountant for advice specific to your circumstances.

What Happens After the Inspection?

You’ll receive a detailed report, typically within 24 hours. This document will:

List any evidence of pests and/or damage
Identify areas that couldn’t be inspected
Outline specific concerns (e.g., active termites, conducive conditions)
Offer recommendations for treatment, repairs, or ongoing monitoring

With this information, you can make an informed decision: negotiate repairs, factor treatment costs into your offer, or reconsider your purchase entirely.

If pests or termite activity are detected, engaging a reliable pest control service quickly is essential to protect your new asset.

How Often Should You Get a Pest Inspection?

For homeowners, we recommend a professional pest inspection every 12 months, more frequently for high-risk environments (such as bushland areas with known termite activity). Regular checks are vital for early detection and ensuring any existing termite protection systems remain effective.

If pests or termite activity are detected, engaging a reliable pest control service quickly is essential to protect your new asset.

Are Pest Inspections Worth It?

Absolutely. A professional pest inspection is a modest investment that can save you significant money, stress, and heartache over the long term. Uncovering hidden pest problems before exchange gives you negotiating power and helps prevent post-settlement shocks. Whether you’re buying your first home or your tenth, knowledge is your greatest defence against preventable issues.
