The Veteran Survey Company is a specialist building surveying practice providing professional damp, mould, condensation and building pathology investigations across South Wales, including Bridgend, Cardiff, Swansea, Newport, the Vale of Glamorgan, Bristol and surrounding areas. Our approach is diagnosis-led. Rather than simply treating visible mould or recommending generic damp-proofing solutions, we investigate the underlying building defect or environmental condition responsible for the problem. Our surveys can investigate: • Damp and mould growth • Condensation and high internal humidity • Penetrating damp and water ingress • Suspected rising damp • Defective rainwater goods, roofing and external fabric • Thermal bridging and cold surfaces • Inadequate ventilation and extraction • Plumbing and drainage-related moisture • Timber moisture and associated deterioration • Insulation and building-fabric defects Investigations may incorporate calibrated moisture measurement, thermal imaging, humidity and environmental assessment, visual building pathology inspection and, where appropriate, inspection of roofs and other difficult-to-access areas. The Veteran Survey Company is RPSA accredited and PCA qualified, with specialist training and qualifications in damp investigation and building pathology above this. Our surveys are undertaken by qualified building surveyors with clear written reports explaining the probable cause of the problem, supporting evidence and practical recommendations for remediation. We work with homeowners, landlords, letting agents, property managers, housing providers and commercial clients. Where remedial work is subsequently required, we also have access to experienced in-house building, roofing and property-maintenance expertise. This means recommendations can be assessed for their practicality while keeping the initial investigation focused on identifying the cause rather than simply selling a treatment. Our objective is straightforward: diagnose the building properly, explain why the problem is occurring and provide proportionate recommendations that address the cause rather than just the symptoms.

Qualifications in Cardiff: Of the 7 specialists listed, 2 hold the CSRT (Certified Surveyor in Remedial Treatment) qualification, 1 is RICS-accredited and 4 have verified insurance.
A survey finds where the moisture is coming from before any work is priced: moisture readings, the pattern of staining and a written report that separates condensation, penetrating damp, plumbing leaks and — only where the evidence supports it — rising damp. That last one matters in Cardiff: genuine rising damp is far rarer than it is diagnosed, and treating a wall that has condensation wastes the money and leaves the problem.
Look for a CSRT (Certified Surveyor in Remedial Treatment) or Property Care Association membership, and prefer a surveyor who isn’t also quoting for the treatment. An independent survey typically costs £200–£400.
