Fire stopping and compartmentation
Compartmentation restored in buildings that stay occupied, installed under BM TRADA Q-Mark third-party certification and recorded seal by seal.
Fire stopping keeps fire and smoke inside the compartment where it starts, which is what makes a stay-put strategy safe. It fails quietly: a cable added through a riser wall, a void left open after a repair, foam where a tested seal should be. We find those gaps, close them with tested systems and leave a record of every one.
We are certified under BM TRADA Q-Mark scheme STD 05b for all four groups of fire-stopping work, and we use tested systems from every major manufacturer, chosen for the substrate, the service and the fire rating. We are not tied to any one brand.
What we do
- Penetration seals around pipes, cables, ducts and mixed services (Group A)
- Linear joint seals at head-of-wall, floor-edge and movement joints (Group B)
- Cavity barriers in ceiling voids, roof spaces and risers (Group C)
- Fire-rated air transfer grilles (Group D)
- Fire-resisting repairs to walls, floors and riser enclosures
- Phased, out-of-hours and ward-by-ward working for buildings that cannot close
From survey to certificate
Survey
We pin and photograph every breach on a floor plan, with the fire rating it needs.
Check for asbestos
Before any void is opened, our surveyors check it. If asbestos is found, our licensed team removes it.
Install
Tested systems installed by our Q-Mark approved installers, labelled at every seal.
Certify
Before and after photographs and a BM TRADA record of installation for every location.

View project →Questions we get asked
Are you third-party certified for fire stopping?
Yes. LE Group holds BM TRADA Q-Mark certificate 2713 for fire stopping installation (STD 05b, Groups A to D), valid to 23 February 2029. The same certificate covers fire door installation and maintenance.
Which products do you use?
Tested systems from all the major manufacturers. We choose the system that is tested for the substrate, the service passing through and the fire rating required, and we record the product against every seal.
What happens if you find asbestos in a riser?
Our surveyors check voids before they are opened. If asbestos is found, our own HSE-licensed team removes it and the fire stopping carries on in the same programme. There is no stop and no second contractor.
Can you work while residents stay in the building?
Yes. Most of our fire stopping is in occupied blocks, hospitals and offices. We phase the work floor by floor, keep escape routes clear, use cordless tools where noise matters and keep residents informed.
