When a non-invasive inspection isn’t enough to uncover the full picture, an invasive inspection provides a deeper investigation into what’s really happening behind walls, under floors, or within hidden cavities.
At Mersey Mould, our invasive inspections are carried out when visible signs of mould or damp indicate a concealed problem — such as trapped moisture, leaking pipes, or hidden condensation points. This process allows us to confirm the exact source of contamination and determine the full extent of any underlying damage.
What’s Involved
• Targeted opening of surfaces such as wall sections, skirting boards, or ceiling voids to inspect behind materials.
• Moisture profiling using advanced meters and probes to map hidden damp areas.
• Air and surface sampling (where required) to test for concealed mould growth.
• Thermal imaging and endoscope cameras to visually inspect hard-to-reach areas with minimal disruption.
• Detailed reporting with photographs, findings, and clear recommendations for remediation.
Why Choose an Invasive Inspection
• Identifies hidden mould that may not show on the surface.
• Pinpoints root causes of moisture ingress.
• Prevents recurring issues by uncovering all affected materials.
• Ensures accurate remediation planning and cost-effective treatment.
Our team works carefully to minimise disruption, restoring all opened areas to a safe and tidy condition once testing is complete. Every invasive inspection is carried out in line with IICRC S520 standards and UK damp & mould guidance, ensuring complete accuracy and compliance.
