Compartmentation survey
Compartmentation survey in Reigate
A compartmentation survey in Reigate checks the hidden walls, floors and voids that keep fire contained inside a building. Find out what a specialist looks for when your fire separation needs checking, and what happens next.

Signs your fire separation needs checking
Gaps around pipes or missing barriers in ceiling voids all point to the same problem: fire can travel between rooms. A specialist reads each sign differently depending on the building's age and layout.

- Pipes passing through walls without sealing
- Service penetrations lack fire stopping. An intrusive fire survey near me would check every pipe entry and recommend how a specialist seals them.
- Missing boards above hallway ceilings
- Cavity barriers may be absent or displaced. A cavity barrier check in Surrey lets a specialist look inside the void and confirm what is missing.
- Daylight visible around a door frame
- The gap suggests poor compartmentation. A service penetration inspection in Reigate helps a specialist find where smoke could pass between spaces.
- Holes left by old wiring or plumbing
- Unsealed routes allow fire to spread. A fire separation check for flats in Surrey determines whether a specialist needs to open up the area.
How a compartmentation survey works

- 1
Initial review of the building
A specialist studies existing floor plans and any previous fire risk assessments before visiting the home to plan the inspection.
- 2
Opening up hidden spaces
The specialist removes small sections of plasterboard or ceiling tiles to examine voids, risers and the gaps around pipes and cables.
- 3
Recording each breach
Every missing barrier or unsealed hole is photographed and plotted on a drawing so the exact location is clear.
- 4
Receiving the report
The specialist compiles the findings into a written schedule showing what needs repair and where a contractor should work.

Questions about compartmentation surveys
Our assessment said compartmentation needs checking, what does that involve?
A fire stopping survey in Reigate means a specialist examines the hidden barriers inside walls, floors and ceilings. They check whether fire can travel from one room or flat to another through gaps around pipes, cables or structural joints. The work usually involves looking inside concealed spaces.
Will you have to open up ceilings and walls, and who makes good afterwards?
An intrusive fire survey requires a specialist to remove small panels or lift boards to see inside voids. The specialist typically arranges for a builder to make good the openings once the inspection finishes. Ask about reinstatement costs before the work starts, since they vary by property.
How much does a compartmentation survey cost for a converted house in Reigate?
Fees depend on the number of floors, the amount of hidden space and how much opening up a specialist needs to do. A converted Victorian house usually takes longer than a modern flat. Request a figure based on your specific layout rather than relying on a general estimate.
Can the survey be done while tenants are still living in the building?
Yes. A specialist schedules the work room by room so residents can stay in their homes. Noisy opening-up is usually confined to agreed hours. Tenants need to grant access to specific areas, so arranging that beforehand keeps the visit short.
Do you look inside roof voids and riser cupboards as part of it?
Roof voids and vertical risers are common paths for fire spread, so a specialist always checks them. This includes looking at cavity barriers in the loft and examining service ducts running between floors. Any missing fire separation check for flats in Surrey will flag these areas.
What does the report show, drawings or photographs of each breach?
The report from a specialist contains both. Photographs show the exact condition of each gap or missing barrier, while marked-up floor plans pinpoint the location. A remedial schedule lists the repairs needed so a contractor knows precisely what to fix and where.
How long before we get the findings and a remedial schedule?
Most specialists deliver the completed report within ten working days of finishing the site visit. Complex buildings with many breaches take slightly longer. The document includes the remedial schedule, so there is no separate wait for the list of required repairs.
Is this the same as the survey my insurer is asking for?
Not necessarily. An insurer might want a general fire risk assessment or a specific check of structural fire protection. Share the insurer's letter with the specialist before booking so they carry out the correct scope. A standard compartmentation survey focuses solely on fire separation.
