Russell McCarthy’s Expert Insights

Russell McCarthy, a leading Building and Pest Inspector in Perth, shares invaluable insights into the subtle indicators of potential structural problems. His expertise sheds light on the importance of understanding these signs early on, ultimately preventing major issues down the line.


Signs of Building Defects

Issues with Doors and Windows

Doors and windows that don’t operate smoothly may seem innocuous, often attributed to aging materials. McCarthy, however, warns that these signs might indicate more severe defects, such as issues with steel lintels, rust, or water ingress. Identifying and addressing these problems promptly is crucial to preventing extensive and expensive repairs.


External Wall Cracks

External wall cracks are a common sight in homes, but their patterns can reveal critical information. McCarthy explains that subsidence or foundation movement is often the culprit, especially in double-brick homes. Recognizing the width and contours of these cracks is essential in determining whether stabilisation measures are necessary.


Internal Wall Cracks

Cracks within the interior walls are often linked to roof or roof frame issues. McCarthy distinguishes between harmless cornice cracking and more concerning vertical cracks, emphasizing the need for a thorough assessment to understand the root cause and implement appropriate fixes.


Sagging or Uneven Roof

A sagging ceiling, sagging roof may appear alarming, and McCarthy details various potential causes, including detached rafters, compromised underpurlins, or natural sagging in older homes. Identifying the specific issue is crucial for determining the most effective and cost-efficient solution.


Damp Patches on the Ceiling

Damp patches on the ceiling can result from various sources, including roof leaks, blocked gutters, or issues with ducted air conditioning. McCarthy advises homeowners to address these problems promptly, as a sagging roof can exacerbate water ingress points, leading to more extensive damage.


Damp Patches on Walls

Damp walls often signal waterproofing issues or leaks, with potential causes ranging from faulty waterproofing membranes to gutter systems allowing water into wall cavities. McCarthy stresses the importance of identifying and rectifying the source to prevent rising damp and other structural concerns.


Signs of Termites

Termites, though small, can cause significant damage. McCarthy explains the signs, such as mud tubes, sand trails, and hollowed-out timber, urging homeowners to conduct annual professional pest inspections for early detection and prevention.
