7 Common Issues Found in a Building Inspection Report in Australia ?

Buying a property is one of the biggest financial decisions you’ll ever make. Whether it’s your first home or an investment property, getting a thorough building inspection report in Australia is not just smart — it’s essential. At Point Building Inspections, we’ve assessed hundreds of properties across Melbourne and regional Victoria, and we’ve seen the same issues come up time and time again.

This guide walks you through the 7 most common defects our licensed building inspectors uncover — so you know exactly what to look for before you sign on the dotted line.

Why a Building Inspection Report in Australia Actually Matters?

Many buyers assume a property “looks fine” at an open house. But what’s hidden behind walls, under floors, and in roof cavities often tells a very different story.

A professional building inspection in Melbourne gives you an independent, unbiased assessment of the property’s structural integrity and overall condition. It also gives you negotiating power — if defects are found, you can request repairs or a price reduction before settlement.

More importantly, it protects you from unexpected repair bills that can easily run into tens of thousands of dollars after you’ve already purchased.

7 Common Issues Found in Building Inspection Reports

Rising Damp and Moisture Problems

Moisture is the single most common issue we find across Melbourne properties, particularly in older homes built before the 1980s. Rising damp occurs when groundwater moves upward through the walls via capillary action, and it’s often invisible to the untrained eye.

Signs include:

• Bubbling or flaking paint near the base of walls
• A musty smell in rooms or cupboards
• Staining or tide marks on internal walls
• Salt deposits forming on brickwork

Left untreated, rising damp can cause serious structural damage, rot timber frames, and create the perfect environment for mould — which poses genuine health risks for occupants.

Our building inspectors in Melbourne use moisture meters and thermal imaging to detect damp that is completely invisible during a standard walkthrough.

Roof Defects and Poor Drainage

The roof is your property’s first line of defence. Yet it’s also one of the most neglected areas of a home. In our building inspection reports, roof-related issues consistently rank among the top findings.

Common roof problems include:

• Cracked, broken, or missing tiles
• Rusting or deteriorating metal roofing sheets
• Blocked or sagging gutters and downpipes
• Inadequate roof pitch leading to water pooling
• Damaged flashing around chimneys, skylights, and valleys

Melbourne’s unpredictable weather — from scorching summers to heavy winter rainfall — accelerates roof wear significantly. Even a minor leak, if undetected, can cause extensive internal water damage over time.

Structural Cracking in Walls and Foundations

Not all cracks are created equal. Hairline cracks in plaster are often cosmetic, but diagonal cracks running from window or door corners, or horizontal cracks in brick walls, can signal serious structural movement.

Foundation problems are particularly common in Melbourne’s inner suburbs due to:

• Reactive clay soils that expand and contract with moisture changes
• Old or inadequate footings that weren’t built to current standards
• Tree roots penetrating and damaging footings
• Poor drainage causing soil erosion beneath the slab

Identifying the difference between cosmetic and structural cracking requires professional experience. This is exactly where a qualified building inspection in Melbourne from Point Building Inspections adds real value.

Timber Pest Damage (Termites and Wood Rot)

While termites are more commonly associated with Queensland, they are absolutely present throughout Victoria and inner Melbourne. A building and pest inspection (combined report) is strongly recommended — because pest damage often hides inside wall cavities and subfloor spaces where it can’t be seen without specialist equipment.

Signs of pest activity include:

• Hollow-sounding timber when tapped
• Mud tubes on stumps or wall linings
• Blistering or sagging floorboards
• Frass (termite droppings) near skirting boards

Wood rot — caused by moisture and fungal decay — is equally destructive. It weakens structural timbers gradually, often without visible external signs. Our inspectors check subfloor stumps, bearers, joists, and roof framing as standard.

Electrical Safety Issues

Older Melbourne homes — particularly those built in the 1950s, 60s, and 70s — frequently have outdated electrical systems that pose genuine fire and safety risks.

Common electrical deficiencies flagged in building inspection reports include:

• Unprotected wiring and exposed conductors
• Absence of safety switches (RCDs) on power and lighting circuits
• Double adapters in place of proper power points
• Outdated ceramic fuse boxes instead of modern circuit breakers
• DIY electrical work that doesn’t comply with Australian standards

A building inspection report will note electrical concerns, but a licensed electrician will need to be engaged for a full electrical safety assessment. Point Building Inspections will always let you know when a specialist referral is needed.

Substandard Building Work and Unapproved Structures

One of the more frustrating — and costly — issues we find is unlicensed or unapproved building work. This includes extensions, decks, garages, granny flats, and carports that were built without council permits or outside of Australian building standards.

The problem? As the new owner, you become responsible for any unapproved structures on the property. Council can require you to demolish or rectify the work at your own expense.

Our building inspectors in Melbourne are trained to identify work that doesn’t meet the National Construction Code (NCC) or BCA standards — whether it’s a poorly built deck, an unapproved laundry addition, or inadequate structural supports on a home extension.

Plumbing Defects and Drainage Problems

Plumbing issues are often hidden until they become expensive emergencies. Common defects found in building inspection reports include:

• Leaking pipes under floors or inside walls
• Slow or blocked drains
• Inadequate hot water system sizing or age
• Roof drainage that discharges too close to the foundation
• Stormwater systems that aren’t connected properly

Melbourne’s clay-heavy soils mean that poor drainage doesn’t just affect comfort — it can actively undermine your home’s foundations over time. We assess drainage flow patterns, downpipe connections, and visible plumbing components as part of every inspection.

How Much Does a Building Inspection Cost in Melbourne?

The building and pest inspection cost in Melbourne typically ranges from $400 to $800, depending on the size and age of the property and whether you’re combining a building inspection with a pest inspection (which we strongly recommend).

At Point Building Inspections, we offer transparent, fixed-fee pricing with no hidden costs. You’ll receive a comprehensive, photo-supported report within 24 hours of the inspection — giving you time to make an informed decision before your cooling-off period expires.
