Five Things a Firestopping Survey Report Must Tell You

Five Things a Firestopping Survey Report Must Tell You

Every firestopping survey ends the same way: a report lands in an inbox, and somebody who was not on site has to decide what to do with it. The decision is easier when you know what a good report must contain before you read a single page. Here is the checklist we would want any duty holder to hold a survey report up against.

1. Every penetration has a location you could walk to

A finding that says "service penetration, level 3, unsealed" is not actionable. A usable report references the drawing, the grid line, the riser or corridor, and ideally a photograph with the compartment line marked. If you cannot hand the report to a contractor and have them find the exact opening without calling the surveyor, the report is incomplete.

2. The compartment line is identified, not assumed

Firestopping only matters where a wall or floor is meant to resist fire. A report should say which elements are compartment boundaries, what rating those boundaries are designed to achieve, and where that information came from. When the fire strategy is missing or out of date, the report should say so plainly rather than guess.

3. Each defect is classified by what it does, not just what it looks like

A gap around a cable tray and a missing collar on a plastic pipe are both "defects", but they fail in very different ways. Look for a report that separates:

  • Unsealed or partially sealed openings
  • Seals installed with the wrong product for the service or substrate
  • Seals that were once correct but have been disturbed by later works
  • Damage to the wall or floor itself, which is not a firestopping repair at all

4. The proposed fix names a tested system

"Make good with fire-rated sealant" is not a specification. A tested firestopping system pairs a named product with a specific substrate, opening size, service type and rating, backed by a test report or assessment. If the recommended remedial work does not say which tested system applies, the repair cannot be signed off with confidence later.

5. There is a clear record of what was not inspected

No survey sees everything. Ceiling voids were closed, plant was running, a tenant refused access. A trustworthy report lists those exclusions so the gaps in knowledge are visible to the next person, rather than silently becoming gaps in the building.

What to do with the answers

If a report you are holding passes all five, the remedial schedule that follows can be priced and sequenced properly, and the evidence trail will stand up when the building's safety case is reviewed. If it fails any of them, ask for the missing detail before work starts. It is far cheaper to ask the surveyor a question than to discover the problem at the next audit.

Updated August 2026: ask for these five things in writing before the survey is booked.
