Work follows the agreed detail and records the opening before it is concealed. Variations in substrate, service configuration or opening size are checked against the proposed system rather than hidden behind a standard description. Additional defects are recorded for a separate decision.

Fire Stopping and Compartmentation
New cables or pipes, removed services, damaged partitions and gaps above ceilings can affect compartment boundaries. Defects may be identified during a risk assessment, specialist survey or refurbishment. The repair should address the actual construction and opening rather than simply fill a visible gap.
Discuss your requirementsDefined services, clearly scoped.
Overview
Before work, establish the intended boundary and required performance. An opening between two ordinary spaces may have a different role from one through a compartment wall or protected shaft. The available design information helps prevent repairs being specified against the wrong requirement.
What the service covers
The scope can include sealing service penetrations, repairing relevant joints and addressing defined defects in fire-resisting construction. The substrate, opening, services and required performance inform the selected system. Larger construction repairs and specialist design input are identified separately where needed.
Outputs include the agreed repair schedule, installation details and completion evidence linked to each location. Photographs, product information and records of the installed arrangement support future inspection. Concealed or unassessed areas are not silently treated as complete because nearby repairs have been carried out.
Select a suitable system for each detail
Fire-stopping products work within defined applications. A product label alone does not prove suitability for every wall, floor, service or gap. The installation detail needs an appropriate technical basis for the actual configuration, including movement and access considerations where relevant.
Government fire-safety guidance explains the importance of maintained fire separation. Repairs should preserve that function. The project distinguishes survey, design, installation and acceptance responsibilities so an unresolved design question is not left for an installer to improvise on site.
Assessment and preparation
Provide drawings, fire strategy, survey references and photographs. Identify required performance, substrate information and the services within each opening. Where the information is incomplete, the initial scope establishes the assessment needed before a repair detail can be selected.
Preparation covers ceiling access, permits, known hazardous materials and coordination with live services. We agree the sequence with other contractors so completed seals are not immediately reopened for additional cables or pipes. The site contact also identifies temporary arrangements where work affects an existing protective boundary.
Delivery and handover
Handover links completion records to the defect schedule and drawings. Your team receives the relevant product and installation information, photographs and outstanding items. Future contractors can then identify repaired locations and understand that further penetrations need a controlled technical detail, not informal reinstatement with an unspecified filler.
Costs, timing and disruption
Cost depends on the number and complexity of openings, required performance, access and condition of the surrounding construction. A small accessible penetration differs from a congested shaft or damaged wall above an occupied ceiling. Survey and design work may be needed before installation pricing is reliable.
The programme allows for access, service coordination and records before concealment. Occupied areas may need segregation and agreed working windows. Making good and ceiling reinstatement are specified. Where construction or service changes alter the detail, the effect on scope is explained before the work proceeds.
Buildings and sectors
Offices and retail premises frequently need coordination above ceilings and around fit-out services. Education and care settings require access planned around sensitive areas. Hospitality and residential buildings can have compartment boundaries associated with sleeping accommodation.
Industrial, warehouse, managing-agent and specialist environments bring different construction and service arrangements. The repair detail follows the actual opening and boundary requirement. View all sectors.
Frequently asked questions
Can every gap be filled with the same product?
No. Suitability depends on the substrate, opening, services and required performance. The repair needs a detail appropriate to the actual configuration.
Does remedial work include a complete compartmentation survey?
Only if specified. A repair programme can use an existing survey, while additional investigation is separately identified where the information is incomplete.
Why are photographs needed before concealment?
They help record the installed detail and its location. Once ceilings or finishes are reinstated, important features may no longer be visible for review.
What happens when another contractor adds services later?
The affected detail needs review and suitable reinstatement. The records should be updated so the compartment boundary remains managed after the alteration.
