External Wall Fire Safety

EWS1 FRAEW & PAS 9980 Opening-Up Specialists

Intrusive surveys, inspection support, fire engineer coordination, and full reinstatement.

Trident Facades Surveys delivers PAS 9980-aligned opening-up and reinstatement works to support compliant FRAEW and EWS1 assessments.

We work directly with building owners and managing agents, and in partnership with fire engineers, surveyors, and consultants, providing safe, precise access to external wall systems so inspections can be carried out accurately, efficiently, and with confidence.

We specialise in the opening up of external and internal walls to expose construction build-ups, cavity barriers, fire breaks, compartmentation lines, and junction details.

Our teams deliver accurately located inspection points, reducing risk, repeat visits, and uncertainty during assessments — even in occupied and high-risk buildings.

All works follow PAS 9980 methodology and are designed to support robust, defensible fire safety reporting.

Fully Managed EWS1 and FRAEW Services

We provide a fully managed route to FRAEW and EWS1 delivery — coordinating access arrangements, permits, PAS 9980-aligned intrusive surveys, structured inspection support, and accredited fire engineer sign-off.

A single, organised process that removes friction, reduces delays, and keeps projects moving while maintaining full compliance and auditability.
