Missing or poorly installed cavity fire barriers put your building at risk.
Unprotected cavities allow fire and smoke to spread rapidly through walls, floors and ceilings. Missing, damaged or unsuitable cavity fire barriers can compromise fire compartmentation, lead to failed inspections and put occupants and property at unnecessary risk.
You don’t want hidden gaps to undermine your building’s fire protection strategy. That is why our fire barrier services include:
- Installing cavity fire barriers: Within concealed wall, floor, ceiling and external wall cavities.
- Protecting compartment lines: Against the hidden movement of fire, smoke and toxic gases.
- Selecting suitable fire safety barriers: For the cavity, substrate and required fire-resistance performance.
- Installing fire stopping barriers: Around vulnerable openings and concealed voids.
- Completing remedial installations: Where previous fire barrier work has failed, deteriorated or been overlooked.
All of these professionally installed fire protection barrier services will contain a fire within its intended compartment, giving your occupants more time to evacuate and limiting damage to the wider building.

We needed a quick quote for works needed based on a fire risk assessment. Eddy was extremely responsive, efficient and professional in providing us with a quote. His help is greatly appreciated and I would not hesitate to get in touch with him for works that may be required in future.

Frequently Asked Questions
Yes. We can inspect the relevant areas and identify missing, damaged or unsuitable cavity fire barriers.
Cavity protection is often hidden behind walls, suspended ceilings, façade systems and service routes. Our team can inspect accessible areas, assess existing installations and explain any remedial work required.
Yes. We regularly provide fire barrier services in occupied residential, commercial, educational, healthcare, and hospitality buildings. We plan access, working hours and affected areas around building users wherever possible to minimise noise, dust and disruption.
Not necessarily. We plan each installation around the building’s layout, occupancy and operational requirements to keep disruption to a minimum.
The level of disruption depends on where the cavities are located and how easily they can be accessed. We will explain this before the work begins.
No. A fire protection barrier provides a defined period of fire resistance rather than resisting fire indefinitely.
Each system must be selected and installed in accordance with its tested specification, the cavity construction, and the required fire-resistance rating.
Yes. We have recognised IFC and SMAS accreditations.
These accreditations give facilities managers, landlords, contractors and compliance teams greater confidence that their fire barrier services are being completed by competent professionals.
We provide fire barrier services throughout Bristol and the wider South West.
