Pre-Purchase Structural Building Inspections — Perth

Buying a home is one of the biggest financial decisions most people will ever make. Before signing the contract, it’s vital to understand the true structural condition of the property. At Perth Master Building Inspectors, we specialise in pre-purchase structural inspections designed to protect buyers from costly surprises hidden behind walls, floors, and roofs.

Our inspections focus solely on the load-bearing and structural components of a dwelling. This includes the foundations, walls, framing, lintels, roof structure, subfloor, and supporting beams. Unlike a general building inspection, a structural inspection excludes maintenance items such as paint, doors, or minor wear and tear. The result is a clear, unbiased report that details any major structural defects that may affect the property’s stability or value. Learn about our structural inspection process.

What Is a Pre-Purchase Structural Inspection?

A pre-purchase structural inspection is a visual assessment of a building’s key structural elements. It is performed by a qualified, registered builder who understands construction methods, Australian Standards, and local Perth building conditions.

The inspection’s purpose is simple — to confirm whether the property shows signs of structural movement, cracking, or deterioration that could compromise safety or require significant repair. These issues are often invisible to the untrained eye, yet they can cost tens of thousands of dollars to fix once you take ownership.

Our reports are prepared in accordance with AS 4349.1 – Inspection of Buildings, the Australian Standard governing pre-purchase inspections. They provide buyers with professional insight into the building’s structural soundness, helping you make informed purchasing decisions before settlement.

What We Inspect

When carrying out a pre-purchase structural inspection, our registered inspectors thoroughly examine all accessible areas of the property, including:

1. Foundations and Footings

We assess visible areas of the foundation for movement, cracking, settlement, or subsidence. In Perth, reactive clay soils are common, and foundation movement can lead to uneven floors, misaligned doors, or structural cracking in walls. Detecting these early is crucial for understanding potential future risks.

2. Structural Walls

Both internal and external load-bearing walls are checked for cracks, bowing, or displacement. We also assess whether previous repairs have been properly completed and whether any structural reinforcement may be required.

3. Roof Structure

The roof cavity is inspected for signs of sagging, inadequate bracing, termite damage, or water intrusion. Roof framing defects are among the most common structural problems found in older Perth homes, especially where modifications or extensions have been made without proper engineering oversight.

4. Subfloor and Supports

For homes built on stumps or raised floors, we inspect the subfloor area where accessible. This includes posts, bearers, joists, and floor framing. We look for signs of rot, movement, or inadequate support that could cause uneven floors or instability.

5. Beams, Lintels, and Load Points

Structural beams, lintels, and junctions are inspected for deflection, rust, or cracking. These components are critical to carrying roof and floor loads safely, so even minor damage can have major implications.

What Is Excluded

It’s important to note that pre-purchase structural inspections are not comprehensive maintenance or cosmetic inspections. They exclude:

• Non-structural components such as doors, windows, tiles, fixtures, or fittings

• Plumbing, electrical, and gas systems

• Roof coverings and external cladding beyond structural performance

• Appliances, finishes, and landscaping

The focus remains entirely on identifying major structural defects, ensuring that you receive a precise evaluation of the property’s core integrity.

Why Structural Inspections Matter in Perth

Perth’s unique environment presents a range of challenges that can impact a building’s structural performance over time. From expansive clay soils to strong coastal winds and temperature fluctuations, these factors can place stress on footings and framing.

Many Perth homes — especially those built during rapid growth periods — may have been constructed under older building codes or without adequate engineering input. Cracking, foundation movement, and roof sagging are not uncommon.

A pre-purchase structural inspection identifies these risks before you buy, helping you avoid:

• Unexpected repair costs after settlement

• Purchasing homes with concealed structural damage

• Insurance or finance complications linked to structural faults

• Disputes with builders or previous owners about the property’s condition

By engaging an independent, registered inspector, you gain confidence that your potential investment has been professionally assessed with no conflicts of interest

Our Inspection Process

At Perth Master Building Inspectors, our process is streamlined and transparent.

1. Booking

Once you contact us, we confirm the property details and schedule a convenient inspection time, liaising directly with agents if required.

2. On-Site Assessment

Our inspector conducts a thorough visual inspection of all accessible structural areas. We use advanced tools to measure movement, check alignment, and assess cracking patterns.

3. Professional Report

Within 24 hours, you’ll receive a clear, photo-illustrated report. It highlights any major structural issues, their likely cause, and recommended next steps. The report complies fully with AS 4349.1 and is suitable for inclusion in finance or settlement conditions.

4. Post-Inspection Support

We take the time to discuss the report findings with you, ensuring you understand what each issue means and how it could impact your purchase decision. Our goal is to provide clarity, not confusion.

Benefits of a Structural-Only Inspection

A structural-only inspection is a cost-effective way to determine a property’s integrity without paying for a full maintenance check.

Key advantages include:

• Focused solely on major structural components

• Faster turnaround time for urgent property contracts

• Compliant with “subject to structural inspection” clauses

• Independent and unbiased assessment

• Performed by qualified registered builders, not general inspectors

For many Perth buyers, this is the preferred option when purchasing established homes or newly built properties where the condition of finishes is already known.

Common Structural Defects Found in Perth Homes

Throughout the years of inspecting Perth properties, we commonly identify:

• Horizontal or stepped cracking in double brick walls

• Subsidence or differential settlement in clay soil zones

• Roof truss deformation or inadequate bracing

• Lintel corrosion above windows or doors

• Inadequate footing depth or moisture-related foundation movement

Each of these issues can affect the long-term safety and resale value of your home. Our detailed inspection reports help you plan remedial works or adjust your offer price accordingly.

Most real estate contracts in Western Australia allow buyers to include a subject to structural inspection clause, giving time to confirm the property’s integrity before proceeding.
