Clear, professional diagnosis and remedial recommendations of damp and timber issues to support your property purchase

Damp can occur for several reasons, including moisture ingress, condensation, poor ventilation, defective rainwater goods, high external ground levels, bridging, salt contamination or issues with the building fabric. Because different types of damp can produce similar symptoms, a professional damp survey helps establish whether the issue is caused by rising damp, penetrating damp, condensation or another moisture-related defect.

Each survey is conducted methodically to provide a clear and accurate assessment of the property. We consider the building as a whole, including construction type, timber layout, ventilation, external factors, and moisture behaviour to ensure an accurate and reliable diagnosis.
Inspection of external elements
Internal assessment of moisture levels and ventilation
Identification of active vs historic timber issues
Inspection of structural timbers for signs of woodworm or decay
Use of appropriate diagnostic tools to support findings
Following the survey, you will receive a detailed written report outlining the condition of the property in relation to damp and timber. Reports are written in a clear, structured format suitable for use by homeowners, homebuyers, surveyors, and property professionals, helping you make informed decisions before proceeding.
