Our comprehensive service includes everything you need to make an informed decision about your property.
We assess signs of subsidence or heave through cracking patterns, level changes, separation at joins, and movement around stumps, bearers and brickwork. This matters in The Basin where sloping sites and mixed footing types can create differential movement between original homes and later additions.
We inspect accessible subfloor areas for damp conditions, poor airflow, water entry points and timber damage that can undermine structural members. In leafy pockets of The Basin, trapped moisture and limited ventilation can accelerate rot and contribute to major defects in flooring support.
We check roof framing for sagging, altered trusses/rafters, inadequate supports and signs of long-term leaks. Roof space issues are a common source of major defects because water entry can quietly weaken timbers and damage ceiling structures over time.
We examine visible roofing, penetrations, flashings, gutters and downpipe connections, focusing on where water may overflow or discharge close to the building. Poor roof water management can drive dampness into walls and subfloors and contribute to ongoing structural damage.
We identify red flags that suggest load-bearing walls have been removed or altered without adequate support, including cracking above openings, uneven ceiling lines and patching patterns. This is especially important in The Basin homes that have been opened up for modern layouts.
We note visible hazards and compliance concerns that can be linked to major defects, such as unsafe stair/handrail conditions, moisture-affected electrical areas, and plumbing leaks impacting structural elements. Where needed, we recommend follow-up by qualified electricians, plumbers or engineers.

In The Basin, major defect risks often relate to moisture and movement. We commonly see subfloor dampness from poor drainage or downpipe discharge, timber deterioration where ventilation is limited, and cracking linked to footing movement on sloping blocks. Renovations and extensions can also introduce issues such as inadequate supports or differential settlement between old and new sections of the house.
Yes, we pay close attention to how the site manages water and how that affects the structure. Where retaining walls are accessible, we look for bulging, cracking, leaning and drainage failures that can push water toward the home or create ground movement. We also review surface drainage paths, downpipe discharge and overflow points that can drive ongoing dampness and structural stress.
We assess cracking by pattern, location, width, direction and whether it aligns with movement indicators like level changes, separation at joins, or sticking doors and windows. Some cracks are minor shrinkage or ageing, but others suggest footing movement, lintel issues, or structural alterations. If indicators point to a major defect, we’ll explain why and recommend the appropriate specialist follow-up.
Older weatherboard homes can be more vulnerable to subfloor and timber-related defects, particularly if stumps, bearers or joists have been exposed to long-term dampness. In The Basin’s leafy environment, blocked gutters, overflowing downpipes and shaded areas can increase moisture exposure. That said, newer homes can also have major defects, especially where extensions, drainage and roof plumbing weren’t executed correctly.
We look for visible signs that plumbing or electrical problems are contributing to major defects, such as leaks affecting framing, water damage around wet areas, or unsafe moisture exposure near electrical components. We don’t perform specialist compliance testing, but we flag concerns clearly and recommend assessment by a licensed plumber or electrician where the risk could impact safety or structural integrity.
