External wall survey Compliant façade condition assessments

External wall surveys provide a structured review of building façades to assess condition, identify defects, and support regulatory compliance. These surveys are particularly relevant for multi-storey residential, commercial, and mixed-use buildings, where façade integrity directly impacts fire safety, weather performance, and structural risk.
At Change24, external wall surveys are carried out by experienced surveyors who understand the technical, regulatory, and management challenges associated with complex facades. Findings are presented in a clear, actionable format to support duty holders in planning maintenance, compliance responses, or further investigation.

Comprehensive external wall survey specialists

Our surveyors bring competence and practical understanding to every assessment. We review façades with an evidence-led methodology, documenting defects and risks that could affect fire safety, water ingress, structural performance, and occupant safety.
Each survey is structured to give duty holders a clear picture of current condition and future risk, enabling better informed decision making.

Why external wall surveys are essential

External wall surveys are often required to satisfy compliance obligations, inform fire safety reviews, or establish baseline condition data where historic information is incomplete or out of date.

Typical drivers for an external wall survey include:

  • Evidence of façade deterioration or defect trends
  • Regulatory requirement or enforcement notice
  • Change in building use or occupancy
  • Refurbishment planning and risk prioritisation
  • Insurance or risk management needs

A well-conducted external wall survey gives duty holders structured, auditable evidence on which to act.

    What our external wall survey includes

    External wall surveys conducted by Change24 typically involve:

    • Visual assessment of cladding, façade components, and substrates
    • Identification of defects, deterioration, or hazardous conditions
    • Review of sealing, waterproofing, and weatherproofing performance
    • Commentary on vertical and horizontal cavity systems where present
    • Photographic evidence and structured findings
    • Prioritised recommendations for action or further investigation

    Reports are produced in a clear and structured format to support compliance, decision-making, and any follow-up works that may be required.

    Understand how these surveys work

    Survey reporting and action planning

    External wall survey reports provide duty holders with a structured condition baseline and a prioritised set of recommendations. Reports can support compliance with applicable guidance and provide practical direction on next steps.

    Where external wall issues intersect with fire safety concerns (for example, combustible cladding or cavity systems), survey findings can be referenced alongside fire risk assessments, fire door surveys, and other compliance activities to give a coordinated picture of risk.
