Fire stopping surveys and repairs
Fire stopping seals the hidden routes fire and smoke use to spread between parts of a building. We survey, seal, photograph and label every penetration, so the compartments your fire doors protect actually hold.
Why compartments matter
Buildings are divided into fire-resisting compartments by walls, floors and fire doors. Every time a pipe, cable or duct passes through one of those walls, it leaves a hole. Unless it's sealed properly, fire and smoke can travel straight past an otherwise good fire door.
We often find unsealed holes in riser cupboards right next to fire doors during inspections. That's why we look for fire stopping problems on every survey.
How we work
Survey
We find the gaps and penetrations in fire-resisting walls and floors: risers, service cupboards, ceiling voids and around door frames.
Seal
Each gap is sealed with a certified product suited to what passes through it and the rating of the wall or floor.
Photograph
Every seal is photographed before and after, so the work can be checked without opening anything up.
Label
Each seal is labelled and logged, giving you a record you can show the fire service or your insurer.
Questions we get asked
What is fire stopping?
Fire stopping seals the gaps and holes in fire-resisting walls and floors, for example where pipes and cables pass through. It keeps each compartment of a building intact so fire and smoke can’t spread through hidden routes.
It matters for fire doors because an unsealed hole next to a perfectly good door undoes the door’s work. Riser cupboards are a common problem area.
