Intrusive Façade Investigations

Specialist Opening-Up Works

We carry out specialist opening-up works to establish how existing external walls are built. By carefully exposing selected areas of the façade, we can see how the wall is assembled behind the visible finish. This allows us to document the materials and construction details present, including insulation, cavities and cavity barriers where visible.

Our findings help the project team compare the construction on site with available drawings and identify potential defects that may warrant further investigation. We record the location of each opening and support our observations with photographs, so the team can trace the evidence back to the area inspected.

We work alongside clients and their appointed fire risk assessors to support Single Building Assessments and other external wall investigations. The evidence we gather helps assessors make informed decisions about further assessment and, where required, develop remedial designs based on the construction found on site.

Why Are They Carried Out?

• Fire Safety & Compliance: Assessing combustible materials and compliance with regulations such as the Building Safety Act and PAS 9980 evaluations.
• Assessments: Providing the empirical evidence required for External Wall Fire Review.
• Defect Diagnosis: Uncovering hidden water ingress, air leakage, or structural movement.
• Remediation Planning: Supplying accurate data for building owners, engineers, and contractors to price and plan repair works properly.
