EWI Inspection Surveys in South East England

At Fitzgerald Surveying Services, we provide professional and independent EWI inspection surveys to ensure your external wall insulation is safe, effective, and performing as intended.

Our aim is to give homeowners and property buyers complete clarity on the condition of their insulation system so they can make informed decisions with confidence.

External Wall Insulation (EWI) systems can greatly improve energy efficiency when properly installed. However, poor workmanship, inadequate detailing, or missing components can lead to serious long-term issues. These include moisture ingress, blocked ventilation, thermal bridging, and deterioration of wall finishes, all of which can compromise your property’s structure and value.

Independent EWI inspections help identify such issues early, before they escalate into costly repairs or warranty complications.

During our detailed assessment, we review external surfaces, render and fixings, drainage and sealant details, ventilation, roof and wall junctions, and, where relevant, internal finishes. Advanced techniques such as thermal imaging or moisture scanning may be used to detect hidden cold spots or damp ingress. Findings are presented in a clear written report supported by photographs, risk ratings, and recommended remedial actions.

Our surveyors are qualified professionals accredited by the RICS and RPSA, offering impartial advice and clear, practical recommendations.

Based locally across Buckinghamshire, Hertfordshire, and the Home Counties, Fitzgerald Surveying Services provides the reassurance that your EWI system is functioning correctly, safeguarding both your comfort and investment.
