Compartmentation survey

Compartmentation survey in Reading

A compartmentation survey reading hidden voids, risers and service penetrations reveals where fire can spread between rooms or floors. The specialist opens sample areas to find breaches that sit above ceiling tiles or behind plasterboard, then reports what needs sealing.

Visual check or opening up concealed voids

Some breaches hide above ceilings and inside risers. Opening sample areas shows the true condition of fire barriers in a building.

Why insurers ask

What a compartmentation survey finds

Insurers request a compartmentation check in Reading when they need proof that fire cannot travel freely between flats or commercial units through shared voids.

The surveyor opens sample areas because pipes, cables and ducts pass through walls above suspended ceilings. A visual walk-through misses those hidden routes entirely.

Opening tiles leaves small access points. The specialist firm explains how many will be lifted and who makes good any disturbed plasterboard or paintwork afterwards.

Sample numbers depend on the building size, age and layout. Older blocks with multiple past alterations usually require more openings than newer builds with documented fire stopping.

The specialist examines hidden barriers above ceilings, inside risers and at service penetrations. They open small sample areas to find breaches that sit out of sight, then report the defects with photographs and floor plan locations.

For a block of flats, a cavity barrier survey checks the horizontal and vertical stops within external walls and roof spaces that prevent flame spreading behind cladding or masonry.

What you receive after the visit

The report records what the surveyor found, where each breach sits and what standard applies. It gives you evidence to act on rather than assumptions about hidden spaces.

  • Annotated floor plans

    Each breach is plotted on a drawing of your layout so contractors know exactly where to work without searching.

  • Photographic schedule

    Images of every opened area show the gap, missing seal or damaged barrier so the problem is clear before anyone visits.

  • Remedial specification

    Notes on the fire rating required for each repair guide the contractor who quotes for and carries out the fixing work.
