Building and Pest Report Explained: Costs, and Why You Need One
A building and pest report is a crucial part of your pre-purchase due diligence. Before making an offer on a property, this inspection helps you uncover hidden issues that could lead to costly repairs down the track. Conducted by qualified professionals, a building and pest report provides a detailed assessment of the home’s overall condition, helping you make a confident and informed buying decision. Here’s what a comprehensive building and pest inspection report includes:
​
​
1. Structural Integrity Assessment
Inspectors thoroughly assess the property’s major structural components, including:
​
-
Foundations, walls, roof structures, and floors
-
Signs of cracking, movement, sagging, or structural weaknesses
-
Defects that may impact safety, long-term durability, or insurance eligibility
A strong structural assessment gives you clarity on the property’s true condition and any potential future expenses.

2. Electrical Systems Check
This ensures the home’s electrical setup is safe and compliant:
​
-
Wiring, power points, switches, and lighting
-
Safety switches, circuit breakers, and meter boxes
-
Identification of outdated or hazardous electrical components
Electrical issues can be expensive to repair and pose serious safety risks, making this section critical.
​
​
3. Plumbing System Inspection
Inspectors evaluate all visible plumbing components:
​
-
Pipes, taps, drains, toilets, and showers
-
Hot water system condition
-
Leaks, corrosion, low pressure, or drainage concerns
Plumbing problems can lead to water damage and mould, both costly issues if not detected early.
4. Moisture and Water Damage Detection
Using specialised tools, inspectors check for:
​
-
Dampness under floors or behind walls
-
Roof leaks, waterproofing failures, or poor drainage
-
Mould growth, condensation, and rising damp
Moisture issues often signal hidden defects that may worsen over time.
​
5. Insulation and Ventilation Review
A full review is performed to assess:
​
-
Roof and wall insulation levels
-
Ventilation in roof spaces, bathrooms, and subfloors
-
Risks contributing to mould, heat loss, or inadequate airflow
Proper insulation and ventilation help improve energy efficiency and overall living comfort.
6. Exterior Condition Evaluation
This includes an inspection of:
​
-
Brickwork, cladding, windows, and doors
-
Decks, balconies, handrails, and steps
-
Driveways, fencing, retaining walls, and drainage systems
Exterior wear and tear can affect safety, compliance, and future structural costs.

7. Pest Inspection (Termites + More)
A pest inspection identifies:
​
-
Termites, termite nests, wood borers, and rodents
-
Evidence of past infestations or damage
-
Conditions that make the property more prone to pests
Pest damage can significantly affect the value and safety of a home, especially in termite-prone areas.
​
How Much Does a Building and Pest Report Cost?
The cost of a building and pest inspection typically starts from around $500 for a standard residential property. Prices vary depending on the size, age, and complexity of the home. In some cases, the selling agent may already have a building and pest report available. These reports are often:
​
-
Available for under $100 upfront
-
Fully payable only if you proceed with purchasing the property
This option can be a cost-effective way to access a professional report early in your property search while avoiding unnecessary expenses.
