Building Defect Investigation Services

We investigate all types of structural and building envelope failures, including damp and water ingress, cracking and structural movement, waterproofing membrane failures, roof leaks, condensation and mould issues, concrete deterioration, cavity wall problems, and below-ground defects. Our forensic approach works across residential, commercial, and industrial buildings from substructure to roof level.

Investigation timescales depend on the complexity and scale of the defect. A straightforward moisture investigation might take a few hours on site, while complex structural failures requiring core sampling and analysis can take several weeks. We'll provide a clear timeframe once we understand your specific requirements.

Not always. We start with non-destructive techniques like thermal imaging and moisture testing. Destructive investigation—such as opening up walls or taking core samples—is only used when necessary to confirm diagnosis or examine concealed construction details. We discuss any intrusive work with you before proceeding and target it carefully to minimise disruption.

Yes. Our investigation reports don't just identify what's wrong—they explain why it's happening and recommend appropriate repair strategies. We specify which materials and methods are suitable, reference relevant British Standards, and outline what successful remediation should achieve. You receive actionable solutions, not just a diagnosis.

Yes. Our team has decades of combined experience in building pathology and forensic investigation. We hold comprehensive professional indemnity insurance, and our work is conducted to British Standards. Our methodologies have maintained an unblemished record with zero claims against our investigations.
