Fire Stopping Certified Fire Stopping Services Certified penetration sealing for service risers, cable trays, pipe runs and ductwork. Installed to tested specifications, photographed and fully documented for inspection and handover. Our Case Studies Request a Quote What Is Fire Stopping and why does it matter? Fire stopping is the process of sealing openings and gaps in fire-rated walls, floors and ceilings to prevent the passage of fire and smoke between compartments. These openings are typically created when mechanical, electrical and plumbing services pass through fire-rated elements during construction. Under Approved Document B of the Building Regulations, all penetrations through compartment walls and floors must be sealed using tested and approved fire stopping systems. This is not optional. Failure to comply can result in failed building control inspections, programme delays and potential legal liability under the Building Safety Act. It is a common misconception that gaps smaller than 40mm do not require sealing. All openings, regardless of size, must be correctly sealed in accordance with the manufacturer’s tested data to ensure compliance and maintain the integrity of the fire compartment. Products we use Tested systems from industry leading manufacturers We work exclusively with the UK’s most trusted passive fire protection manufacturers. Every product we install is third-party tested, fully certified and matched precisely to the tested detail your project requires. What We Do: We deliver a fully managed fire stopping service from initial survey through to final handover, covering every stage of the process to ensure your project is compliant, fully documented and delivered on programme. Survey & Assessment: Before any installation begins, we carry out a detailed survey of the building to identify all penetrations requiring fire stopping. We cross-reference the fire strategy and architectural drawings against site conditions, picking up discrepancies between design intent and what has actually been built. Where penetrations have been routed without consideration for fire stopping, a common issue when we are engaged after M&E installation, we identify the problem early and work with the site team to agree a practical solution before it becomes a programme risk. What We Do: Installation: Our installers are FIRAS-certified and trained to install fire stopping systems strictly in accordance with the manufacturer’s tested specifications. We work with products from the UK’s leading manufacturers including Quelfire, Rockwool, FSi and Promat, selecting the correct system for each individual penetration based on the substrate type, service configuration, annular gap and required fire rating. Whether it is a single cable penetration through a plasterboard partition or a complex multi-service transit through a concrete floor slab, every seal is installed to the tested detail; not approximated, not improvised. We cover the full scope of fire stopping applications including service penetrations for cables, cable trays, conduit, pipework (both combustible and non-combustible), ductwork, busbars and mixed-service openings. We also seal linear gap joints at wall-to-floor and wall-to-ceiling junctions, head-of-wall details and any other breaches in the fire compartment line. What We Do: Documentation & Traceability: Every seal we install is photographed, logged and recorded with full traceability back to the manufacturer’s tested detail. Our handover documentation includes photographic evidence of each installation, the product and test reference used, the substrate and service configuration, and confirmation that the seal has been installed within the scope of the manufacturer’s approval. This documentation is prepared to satisfy building control, third-party inspectors and Gateway sign-off without delay or rework. Remedial Fire Stopping: Not every project starts with a clean slate. We regularly carry out remedial fire stopping works where previous installations have failed inspection, where seals have been damaged by follow-on trades or where fire stopping was missed entirely during the original build. We survey the extent of the deficiency, agree a scope of remedial works and carry out the installation with the same level of careand documentation as any new build project. Request a Quote Frequently Asked Questions What standards do your fire stopping installations meet? All of our fire stopping installations are carried out in accordance with BS EN tested standards and comply with Approved Document B of the Building Regulations. We are FIRAS certified, meaning our work is subject to regular independent audit by Warringtonfire. Do you provide documentation for every fire stopping installation? Yes. Every seal is photographed, logged with a unique reference number and compiled into a detailed record of works. This documentation includes the products used, the tested detail reference, the location of the installation and the operative who completed the work. Can you work around other trades on site? Absolutely. We coordinate with your site team to sequence our fire stopping works around other trades. With early engagement, we can plan our programme to avoid clashes and keep your project moving without delays. Do gaps under 40mm still need fire stopping? Yes. It is a misconception that gaps under 40mm do not require sealing. All openings in fire-rated elements must be sealed in accordance with the manufacturer’s tested data, regardless of size. Which fire stopping products do you use? We work with industry-leading manufacturers including Rockwool, Quelfire, Nullifire, Protecta and Promat. The specific product is selected based on the tested detail required for each penetration type and substrate combination. Contact
