From damp and structural movement to roof failures and water ingress, our team of licensed surveyors provide investigation and diagnosis for all building defects.
British weather, ageing materials and decades of alterations mean that properties of any age can develop defects; cracks, damp, water ingress, roof problems, structural movement and the rest.
Diagnosing what's actually wrong, rather than what's commonly assumed, is the first step toward fixing it. Our defect investigations give you a clear, evidenced view of the cause, the consequence and the remediation options.

Infrared cameras reveal things invisible to the eye; hidden moisture behind walls, missing insulation, thermal bridging, even live electrical issues.

Investigation of cracks in walls, floors, ceilings or masonry to determine cause (thermal movement, settlement, subsidence, structural failure), severity, and whether monitoring or remediation is needed.

Specialist investigations identifying the type and source of damp (rising, penetrating, condensation, leaks, failed DPC) using moisture meters, thermal imaging and visual diagnosis.

Assessment of roof condition and any defects: slipped tiles, failed flashings, lead work, gutter problems, structural roof issues. We often utilise drone surveys for safe access on steeper or higher roofs.

Coordinating repairs and maintenance across a residential block of flats on behalf of a freeholder or management company.

Older buildings, typically pre-1919 (Georgian, Victorian, Edwardian), built with traditional methods such as solid stone or brick walls, lime mortar, breathable construction, slate roofs, and timber.
Most defects look like something obvious... that crack must be subsidence, that damp must be rising. Often it's not.
A proper investigation looks at the building as a system: how water moves through it, how it settles, how its parts age in relation to each other. Diagnosing accurately is the difference between paying for the right repair and paying twice.

Tell us about the property and what you're seeing. We'll arrange a meeting to talk through the investigation, scope and how we can help.
