“Site survey before façade installation”
A site survey before façade installation is a critical step in ensuring a compliant and durable external wall system. Before any rainscreen cladding or fire-rated materials are specified, the existing structure must be carefully assessed. This includes reviewing substrate condition, structural load capacity, cavity depth, insulation requirements and fire compartmentation details in line with Approved Document B.
In London and across the UK, many façade issues originate from assumptions made without proper on-site evaluation. Inaccurate measurements overlooked structural tolerances or missing cavity barrier planning can lead to non-compliance, delays and costly remediation after inspection. A detailed site survey identifies potential risks early and supports accurate material specification.
Drainage paths, ventilation gaps, fixing zones and interface details around windows and openings must all be verified before installation begins. This ensures the rainscreen system performs correctly against water ingress and fire spread.
