Compartmentation Surveys & Remedial for Wandsworth buildings
Compartmentation divides a building into fire-resisting cells so a fire cannot spread. Decades of M&E penetrations, refurbishments and lazy reinstatements compromise it. We survey, document and remediate to give you a defensible record.

Why this matters in Wandsworth
The Building Safety Act 2022 requires a digital golden thread of information for higher-risk buildings. Compartmentation evidence is a core part of that — and a critical defence in any enforcement action.
