Indigo Systems carries out fire stopping surveys for London buildings where service penetrations, voids, risers, ducts, cables or refurbishment works may have affected compartmentation.
What a fire stopping survey checks
A survey helps identify visible breaches in fire-rated walls, floors and ceilings, then gives facilities teams or contractors a clearer view of where sealing, repair or further investigation may be required.
- Pipe, cable, tray and duct penetrations
- Risers, service cupboards and plant areas
- Linear gaps and construction joints where visible
- Previously installed fire stopping that appears damaged or incomplete
- Areas affected by recent M&E, cabling or refurbishment works
- Photo records and practical remedial recommendations
Why compartmentation matters
Fire stopping protects the integrity of compartment lines. When openings are left unsealed or poorly repaired, smoke and fire can spread through hidden routes that are not obvious during normal building use.

Frequently asked questions
When should fire stopping be surveyed?
A survey is useful after refurbishment, cabling, mechanical works, changes to risers or where there is uncertainty about existing compartmentation.

Yes. Access needs to be managed, but many surveys can be planned around live building operations.
Can Indigo carry out remedial works after a survey?
Yes. Indigo can support remedial fire stopping works where required and practical.
