[Request Estimate](/contact) [07400 436839](tel:+447400436839) 5 years' passive fire experience. Certified systems only, every penetration photographed. Passive fire experience 5 years Third-party certification BM TRADA (via Sully Form Ltd) Employers' liability £10M Public liability £5M Accreditations Constructionline Silver · SafeContractor · SIPS Service overview ## What this service is — and when you need it. What it is Sealing of service penetrations, linear gaps and construction joints to certified, tested detail — using batt-and-sealant, mortar, collars, wraps and mastic systems appropriate to the substrate, service type and fire rating required. Who it's for Housing associations, HRB duty holders, principal contractors, M&E contractors, healthcare estates and commercial fit-out teams needing compartment lines reinstated after works or defects. When it's needed After M&E first-fix and second-fix, following FRA compartmentation findings, during refurbishment, on new build handover, or when riser and cupboard surveys reveal unsealed penetrations. Why a specialist matters Fire stopping is a certified system, not a bucket of pink foam. The wrong material, wrong depth, or wrong backing for the service and substrate means the compartment line looks sealed and isn't. A specialist selects and installs the right system, then evidences it. What happens if this is ignored ## The consequence of leaving it. - Unsealed penetrations allow fire, smoke and hot gases to bypass the compartment line — often into the exact riser or corridor that forms the escape route. - FRA compartmentation actions left open drive enforcement escalation and, on HRBs, mandatory reporting. - Insurance-side reviews increasingly ask for evidence per penetration. Missing evidence is treated as missing work. Common mistakes ## What we see go wrong. - Using generic expanding foam around a penetration — it is not a fire stopping system. - Applying intumescent mastic without the correct backer or depth — the seal fails at test spec. - Sealing plastic pipe without a fire collar or wrap — plastic pipes require a collapsing/intumescent detail. - No photo per penetration — the seal is invisible behind cabling and can't be evidenced after the fact. Our process ## A step-by-step system, from survey to handover. 1. Step 1 Survey of compartment lines Walk the risers, corridors, service cupboards, plant rooms and communal ceiling voids to log every penetration, gap and joint against a floor plan. 2. Step 2 System selection Each penetration paired with a tested, certified system appropriate to substrate, service type, aperture size and required rating (typically 60 or 120 minutes). 3. Step 3 Preparation and installation Aperture prepared to system requirements, backing installed to the correct depth, sealing installed to the system's tested schedule. 4. Step 4 Per-penetration photograph Every completed penetration photographed and referenced to a location on the floor plan. 5. Step 5 Record and handover Record of Insulation, product datasheets and photo pack handed over for the building safety file and FRA close-out. Why clients choose Flame Solutions ## Specific outcomes, not vague promises. Compartment line actually restored Certified systems installed to their tested detail — not generic foam, not decorative mastic. Evidence per penetration Every seal photographed and referenced — the FRA re-inspection has what it needs. One specialist owning the compartment No handoff between the M&E installer and the FRA close-out contractor. Fewer callbacks after M&E works Coordination with M&E first- and second-fix reduces the number of times you re-open the ceiling void. Faster FRA close-out Action-by-action evidence pack means the assessor signs off without a second site visit. Defensible safety file The Record of Insulation and datasheet pack survive scrutiny from insurers, enforcement and the Building Safety Regulator. In detail ## Materials, methods and where each applies. The technical detail behind how fire stopping services is scoped, specified and installed to certified detail. Batt-and-sealant Sealing around cables Certified systems only ### Batt-and-sealant systems Coated stone-wool batts with a sealant overlay are the standard system for larger apertures in blockwork, drylining and concrete — carrying cable trays, bundles, multi-service penetrations and larger plastic pipework. Batt depth, coating side and sealant depth all come from the certified system datasheet, not from site judgement. ### Fire collars, wraps and pipe closures Plastic pipework passing through compartment lines needs a collapsing intumescent detail — a collar for larger pipes, a wrap for smaller — sized to the pipe outer diameter and rated to the required minutes. Metallic pipework has a separate detail with its own insulation and sealant requirements. ### Mortar and concrete-substrate details Larger penetrations in concrete slab and blockwork are sealed with cementitious mortars to a certified depth, often in combination with sealant. Overfill and underfill both fail the test detail. ### Sealants — intumescent, acoustic and hybrid Sealant selection is driven by joint width, substrate and whether cold-smoke and acoustic performance are required alongside fire. Not every 'fire' sealant is intumescent, and not every intumescent product is rated for the joint width you're sealing. ### Coordination with dampers and ductwork Ductwork penetrations are typically the responsibility of a damper rather than the fire stopping around them — but the perimeter seal around the damper still has to be installed as a certified detail. ### What we do not offer We do not offer a product warranty on the sealed system. The certified system carries its own third-party test evidence; our commitment is to install strictly to that tested detail and to provide the Record of Insulation and datasheet pack.

How much does fire stopping cost? + Priced by penetration count, size and system used. A riser survey with sixty small penetrations sits in a different band to a plant-room bulkhead. Send drawings, a survey list or an FRA extract and you'll get a fixed quotation. How long does the work take? + A typical residential riser with fifty to eighty penetrations is a few days of on-site work. Large commercial voids and multi-floor riser programmes are phased by floor and access window. Do you provide a warranty on fire stopping? + We do not offer an additional warranty. The certified system's test evidence and the manufacturer's datasheets are the assurance. What you get from us is documented proof — Record of Insulation, per-penetration photo, datasheets — that the system was installed correctly. How long does a fire stopping seal last? + Correctly installed and undisturbed, a certified fire stopping system performs for the life of the compartment line. Most failures come from later trades cutting through the seal to run a new cable — which is why every re-entry needs the seal reinstated. Can you seal around cables installed by our M&E contractor? + Yes. We work alongside M&E first- and second-fix teams so seals go in as the services are completed rather than being retrofitted through finished ceilings. Do you produce a Record of Insulation? + Yes — every job is handed over with a Record of Insulation, per-penetration photo pack and the product datasheets used. Do you work on live, occupied buildings? + Yes. Most of the work is in occupied residential and healthcare buildings; access is phased and dust is controlled. Which areas do you cover for fire stopping? + London, Kent, Sussex, Surrey and the surrounding boroughs including Croydon, Sutton, Bromley, Sevenoaks and Crawley. Can you close out FRA compartmentation actions on our behalf? + Yes — send the FRA and we return a priced programme, action-by-action, closed out with evidence. ## Get a fixed quotation for fire stopping services.
