Compartmentation survey, Harrow

- Breaches photographed on site
- Locations recorded for each fault
- Arranged for occupied homes

What gets checked
Tracing the fire barriers
- Ceiling voids
- Panels are lifted so the specialist can inspect the space above, looking for gaps around pipes and cables that break the fire barrier.
- Service risers
- Vertical shafts carrying water and wiring are opened at each floor to check the sealing between levels.
- Cupboards and ducts
- Storage areas built into walls are examined where they meet partition lines, since these often hide missing fire stopping.
Why it matters
Proving fire separation in your building
When the fire service asks you to prove fire separation, a fire compartmentation check in Harrow is what they mean. It maps the barriers meant to hold back smoke and heat.
- Recording each breach Every gap found during the fire separation inspection in Harrow is logged with its exact location and a photograph so you know what needs attention.
- Mapping the findings The compartmentation report blocks in Harrow receive shows each breach on a drawing of the floor plan, marking where the barriers have failed.
- Hidden gaps A ceiling void fire survey in Harrow reveals problems behind plasterboard. Pipes and cables installed after construction often leave holes that compromise the original design.
- Stopping the spread A fire stopping survey in Harrow identifies where seals have degraded or were never fitted, leaving routes open for smoke to travel between separate dwellings.
What shapes the cost of the survey
No two buildings are identical. The amount of work depends on how much space needs opening up and how many floors the specialist must examine.

- Number of floors
- Each additional storey adds more ceiling voids, risers and cupboards to open and record.
- Access to voids
- Tight loft hatches or locked service cupboards slow the inspection down compared to easy access panels.
- Building age
- Older homes often have altered layouts and missing fire stopping, requiring closer examination of each wall and ceiling line.
- Occupied rooms
- Working around furniture and residents means the specialist moves carefully, which takes longer than an empty building.
The specialist explains the cost for your particular home before anything is agreed.
