External wall insulation: workmanship, defects & evidence.

We offer remote reviews of system specifications, drawings, photographic evidence and previous reports, as well as nationwide on-site examinations of safely accessible EWI workmanship. A detailed written report can be agreed where a formal record of observations and technical references is required.

Site visits are arranged subject to availability and a confirmed fee, including travel and accommodation where needed. Remote document reviews are not a substitute for testing or examination of concealed layers.

Where the workmanship or performance of an EWI installation is questioned, we review the visible condition, relevant project records and system requirements. A conflict check comes first, particularly where a supplier or manufacturer has been involved.

• Cracking, debonding and visible finish defects
• Window and door reveals, corners and termination details
• Plinths, penetrations and interfaces with adjoining work
• EPS and mineral wool system information where relevant
• Comparison of installation records with supplied specifications
• Independent second opinion on previous technical reports
• Visible workmanship and remedial proposals

A visual inspection cannot confirm concealed fixings, fire performance, moisture conditions or every layer of the installed system. We record evidence gaps and identify where an appropriate specialist or destructive investigation is required.

A clear specification establishes the proposed system, preparation, finishes and critical details. We can compare the stated requirements with drawings and relevant manufacturer guidance, helping identify ambiguity before work proceeds.

Reviews may address substrates, compatibility between layers, reinforcement, beads and junctions, weather constraints and installation sequence. Recommendations are specific to the agreed consultancy scope.
