Intrusive Surveys

Expert Opening-up Works and Material Sampling for PAS 9980 and FRAEW Compliance.

We provide controlled PAS 9980 opening-up works tailored to your inspection strategy, scope, and reporting requirements. You define the exposure points, and our team handles the site delivery, access logistics, and full weather-tight reinstatement. We ensure your data is captured accurately on the first visit with minimal disruption to residents.

Our focus is purely on practical execution: making your external wall inspections easier, faster, and completely reliable.

Let Us Support Your Next Project

Trusted by Property and Construction Professionals.

We work with a wide range of clients including fire engineers, façade consultants, surveyors, and specialist contractors—delivering controlled PAS 9980 opening-up works that are precise, efficient, and fully aligned with inspection scope and reporting requirements.

Our role is to support FRAEW and façade assessment programmes by providing accurate, first-time opening-up of external wall construction, helping reduce delays, avoid repeat visits, and ensure inspection requirements are met without disruption to wider building operations.

Designed to Support Your Inspection Strategy

We execute your professional instructions precisely, ensuring you capture required physical evidence without site delays or repeat visits.

Poorly executed opening-up works compromise data and disrupt inspection schedules. By working strictly to your specified scope, we avoid unnecessary exposure and structural disturbance. This ensures clean evidence gathering, faster assessments, and fewer return visits.

All works align with PAS 9980 methodology, exposing construction build-ups, cavity barriers, and key junction details accurately. We provide comprehensive, high-resolution photographic logging at every stage, giving you clear digital evidence of hidden defects and material layers. We act as a practical extension of your team, translating technical requirements into safe, controlled site delivery within occupied buildings.

Operating under strict RAMS (Risk Assessments and Method Statements), we manage all health, safety, and working-at-height compliance natively. Following inspection, all areas are reinstated using matching or suitable materials to leave the building secure and weather-tight.

If required, we can also handle independent laboratory sample testing to verify material compositions. Throughout the process, we maintain a resident-sensitive approach to minimise disruption to occupants and daily building operations.
