The problem
Material and coating failure, timber decay and structural moisture require building pathology expertise. Causation may be design deficiency, workmanship failure, material specification error or environmental exposure.
Building pathology is the systematic study of building defects and failures. It applies scientific method to determine why materials have failed, when the failure originated and who is responsible. Common investigations include render and coating failure, timber decay (wet rot, dry rot), masonry deterioration, concrete carbonation and structural moisture. Building pathology report standards require instrument-verified data and clear causation.
The risk
Developer defect liability, warranty claims and insurance disputes depend on clear causation and scope. Without forensic analysis, the extent of damage and the responsible party remain contested.
Material failure claims can involve six- and seven-figure remedial costs. Render failures on new developments, timber frame moisture problems and foundation damp are among the most costly building defects. Our forensic approach quantifies the defect, traces causation and provides the evidence needed for resolution.
Our investigation
We combine systematic visual inspection with instrument-led diagnostics: moisture mapping, thermal imaging, material sampling and, where required, laboratory analysis. Building pathology methodology — no remedial interest.
- Systematic defect survey and photographic record
- Moisture mapping of affected materials and substrates
- FLIR thermal imaging for concealed moisture, thermal bridging and insulation defects
- Material sampling for laboratory analysis where required (timber, render, concrete)
- Review of design documents, specifications and construction records where available
- Environmental exposure assessment
- Causation analysis — design, workmanship, material or environment
Findings
Causation, type and extent of material failure are documented with instrument-verified data. Timber decay is categorised and mapped. Coating and render failures are linked to substrate conditions, application method or environmental exposure.

- ✓ Defect mapping and extent quantification
- ✓ Photographic and thermal evidence
- ✓ Moisture data and material testing results
- ✓ Remedial scope guidance (no contractor recommendation)

Frequently asked questions
- What is building pathology?
- Building pathology is the study of building defects and failures using systematic investigation and scientific method. It answers three questions: what has failed, why it failed and who is responsible. It draws on material science, construction technology, physics and environmental science.
- Can you investigate timber frame buildings?
- Yes. Timber frame construction presents specific moisture risks — interstitial condensation, vapour barrier failure and timber decay. We use moisture mapping, thermal imaging and targeted sampling to assess timber frame integrity.
- Do you provide expert reports for warranty claims?
- Yes. Our building pathology reports are suitable for NHBC, LABC and Premier Guarantee warranty disputes. We provide clear causation, defect quantification and remedial scope.
