Forensic, Legal & Insurance Damp Investigations

Independent expertise for disputes, insurance claims, and moisture-related building failures.

Durndell Building Surveyors provide impartial, evidence-based investigations to support insurers, loss adjusters, legal teams, and building owners when moisture or damp-related defects become contentious. We act as independent Chartered Building Surveyors, specialising in damp ingress, condensation failures, latent defects, and construction detailing issues where robust evidence is essential.

When is a Forensic Damp Investigation Required?

  • Ongoing insurance claims where liability for water ingress, damp, or mould is disputed.
  • Latent defects or new-build warranty claims relating to failed damp-proofing or design detailing.
  • Disputes between contractors, developers, or clients over workmanship or compliance with BS 5250 and BS 8102.
  • Cases requiring expert validation of existing reports or conflicting damp diagnoses.

Our Forensic Investigation Process

Each investigation follows a clear, defensible methodology designed to stand up to scrutiny by insurers, legal professionals, or warranty providers:

  • Non-invasive diagnostic survey to establish moisture distribution and potential ingress points.
  • Targeted moisture profiling using calibrated instruments and surface/embedded readings.
  • Salts and materials analysis to identify contamination and trace moisture source (groundwater vs. plumbing).
  • Thermal imaging and hygrometric assessment to isolate cold bridging, leaks, or interstitial condensation.
  • Construction detail review against as-built drawings, manufacturer guidance, and British Standards.
  • Independent reporting — clear, factual evidence suitable for warranty, insurance, or litigation purposes.

Deliverables

Our forensic damp reports are concise, structured, and supported by photographic, moisture, and thermal data. Each report includes:

  • Root cause diagnosis supported by measured evidence.
  • Clear explanation of mechanism (e.g. capillary rise, bridging, design error, or condensation).
  • Causation narrative suitable for legal or insurance submission.
  • Recommended remedial options proportionate to risk and liability exposure.
