A compartmentation survey has identified defective fire stopping in your building. The report is now in the hands of the Owners’ Management Company (OMC), facilities manager or building owner, and decisions are needed about assessment, priorities and repairs.
Some findings may be straightforward. Others involve concealed construction, mixed building services or penetrations that have been altered repeatedly over the building’s lifetime.
The natural response is to obtain quotations and start closing out the defects.
But a list of defects is not always a complete specification for the work needed to correct them.
Before remediation begins, the findings need to be understood, any urgent concerns addressed and the proposed repairs assessed against the construction that is actually present.
What Happens When a Fire Compartmentation Survey Identifies Defects?
A compartmentation survey identifies weaknesses or suspected weaknesses in the fire-resisting construction intended to restrict the spread of fire and smoke. Once defects are recorded, the building owner needs to arrange competent assessment, determine appropriate actions and establish a suitable remediation programme.
A survey may identify unsealed service penetrations, damaged fire stopping, missing or unsuitable penetration seals, gaps at compartment junctions or areas where the condition of the fire barrier cannot be confirmed.
A visible gap around a service passing through a protected escape route may require different consideration from a defect elsewhere in the building. An inaccessible penetration may need further investigation before anyone can determine whether the existing installation is suitable.
The report should provide a basis for those decisions, although it may not answer every question about the required repair. Its scope also matters. A survey based on accessible areas and visual inspection cannot necessarily establish the condition of concealed construction throughout a building.
Understanding what a fire stopping survey involves is useful when reviewing the findings and deciding whether further investigation is needed.
Receiving the report is the beginning of the remediation process. Obtaining a quotation does not, by itself, establish that every defect has been properly understood.
Why Should Identified Fire Stopping Defects Be Assessed Promptly?
Defective fire stopping may compromise the performance of compartment walls and floors, allowing fire or smoke to spread beyond the area in which it starts. The consequences depend on the building and the nature of the defect, but postponing assessment leaves an identified weakness unresolved.
Passive fire protection is rarely noticed during ordinary building use. It sits behind ceilings, within risers, around pipework and cable containment, and at junctions between construction elements.
A compartment wall is intended to provide a specified level of fire resistance. Where services pass through that wall, the penetration needs an appropriate fire stopping arrangement so the intended performance is maintained.
If the opening is inadequately sealed, the compartment boundary may not perform as intended.
That does not mean every defect will result in a catastrophic failure. Fire safety depends on multiple measures, and the significance of individual findings requires competent assessment. It does mean that an identified weakness deserves a proportionate response, including consideration of any necessary interim precautions.
Delay can also make the eventual work more difficult.
Consider an apartment development where a survey identifies defects in several communal risers. If repairs are assessed before a planned services upgrade, the work may be coordinated with that programme. If additional services are installed first, the penetrations may become more congested and existing seals may be disturbed.
Further alterations can reduce access to areas that were previously straightforward to inspect or repair.
Early action does not guarantee lower remediation costs. It does, however, provide an opportunity to investigate the findings, establish priorities and coordinate the necessary work before further changes complicate the installed condition.
How Should Building Owners Assess Fire Compartmentation Defects Before Repairs Begin?
Before commissioning repairs, the survey findings should be reviewed by appropriately competent professionals against the building’s fire strategy, the affected construction and the conditions recorded on site. This helps establish which defects can be specified for repair and which require further investigation.
Consider a service riser in an apartment development built in the early 2000s.
The survey identifies several penetrations through compartment floors. Some have visible gaps around pipework. Others contain older sealing materials, additional cables and services installed after the original construction.
The report may identify the locations and describe the apparent defects, but the appropriate remediation detail can depend on matters that are not immediately visible.
The floor construction, opening dimensions, service types, insulation and available access all affect what can be installed.
In some cases, an existing seal may need to be removed to establish the underlying condition. In others, further investigation may be necessary before a suitable tested system can be selected.
These conditions also explain why service riser fire risks deserve particular attention in buildings that have undergone repeated alterations.
A contractor should not simply fill the visible gap and assume the compartment has been restored.
The objective is to establish a suitable fire stopping arrangement for what has actually been built.
Can Every Fire Stopping Defect Be Repaired Using the Same System?
No. Fire stopping systems must be suitable for the particular construction, services and installation conditions. A detail appropriate for a metallic pipe through a rigid wall may not be suitable for a mixed-service penetration through a plasterboard partition or a floor containing insulated pipework.
The proposed system must be assessed as a complete arrangement. The supporting construction, opening dimensions, service materials, insulation and separation distances can all affect suitability.
The presence of several services within one opening does not automatically mean that a particular repair is appropriate. The proposed detail needs to be supported by relevant technical evidence and capable of being installed under the conditions present.
Selecting a familiar product is not a substitute for establishing whether the complete installation is suitable.
Who Decides Which Fire Stopping Defects Should Be Addressed First?
The order of remediation should follow a competent assessment of the defects, the building’s fire strategy, occupancy and relevant risks. A building owner or OMC should not assume that the largest visible opening is necessarily the most significant finding or that every defect carries the same urgency.
A survey may identify defects in protected corridors, service risers, plant areas and compartment boundaries between different occupancies.
A relatively small opening in an important fire-resisting boundary may warrant prompt attention. A larger opening elsewhere may require a different response depending on its location, function and the wider fire safety arrangements.
The client’s fire consultant or other appropriately competent professional should help determine the appropriate priorities and whether interim precautions are needed.
For the building owner, an agreed sequence provides a reasoned basis for deciding what requires immediate attention, what needs further investigation and how the remaining works should be programmed.
It also gives an OMC or managing agent a clearer basis for explaining the proposed works to residents and apartment owners.
What Affects Fire Stopping Remediation Costs?
Fire stopping remediation costs depend on the number and type of defects, the construction involved, access conditions, required systems and the extent of associated work. Two buildings with similar defect counts can require very different programmes, particularly where penetrations are concealed or services must be coordinated.
A defect schedule may record 100 penetrations, but that figure alone says relatively little about the likely cost.
Some openings may be accessible from a communal corridor. Others may be behind finished ceilings, inside occupied apartments or within congested risers.
A straightforward service penetration through a known wall construction is a different proposition from an opening containing several generations of pipework and cable containment.
Costs may also be affected by opening up, making good, temporary protection of existing services, access arrangements and coordination with electrical, mechanical or other specialist contractors.
Where the condition behind a finished surface is unknown, further investigation may be needed before the scope can be priced with reasonable confidence.
Accurate scoping is therefore important. It allows the client to distinguish the cost of the fire stopping installation itself from the associated work required to reach, prepare and reinstate the affected area.
How Can Fire Stopping Remediation Be Planned in an Occupied Building?
Remediation in an occupied apartment building requires planning around residents, communal areas, building services and access to concealed construction. The work must be technically suitable, but it also needs to be organised so that disruption is understood and essential building functions are protected.
A service riser in a communal corridor may be relatively accessible. A penetration concealed above a ceiling inside an occupied apartment requires a different approach.
Residents need appropriate notice of access requirements, likely disruption and the areas affected. OMCs and managing agents also need sufficient information to explain the proposed programme and respond to practical concerns.
The work plan should address:
- Access to apartments, ceilings and risers: Identify where entry or opening up will be required.
- Coordination with building services and other contractors: Establish whether existing services need protection, adjustment or specialist attendance.
- Inspection before completed work is concealed: Allow the relevant parties to review installations while they remain accessible.
- Reinstatement responsibilities: Confirm who will repair ceilings, enclosures and finishes disturbed by the works.
- Unexpected concealed conditions: Agree how additional findings will be assessed, authorised and incorporated into the programme.
These arrangements are particularly important where the initial survey could not establish the full condition of concealed compartment boundaries.
What Can Go Wrong When Fire Stopping Repairs Are Rushed?
Rushed remediation can result in unsuitable repair details, incomplete coordination or inadequate records of concealed work. Closing defects quickly is not the same as demonstrating that the required fire-resisting construction has been appropriately reinstated.
Installation sequence deserves particular attention.
A penetration may be correctly sealed, inspected and recorded, only for another contractor to introduce an additional cable or pipe through the completed arrangement.
The original installation may no longer match the detail that was assessed and documented.
Agree how later service installations will be controlled and how any disturbed fire stopping will be reassessed.
Where a penetration changes, the project team needs to establish whether the existing arrangement remains suitable or whether a revised detail is required. The resulting work should be inspected and the installation records updated accordingly.
Without that control, a defect register may show an item as complete even though the condition on site has subsequently changed.
What Should Be Included in a Fire Stopping Remediation Tender?
A remediation tender should define the known defects, proposed scope, relevant technical requirements, access arrangements and expectations for inspection and documentation. It should also identify uncertainties that may affect the work, particularly where concealed conditions cannot be fully assessed before opening up.
For a substantial apartment or commercial building, the tender information may draw on the compartmentation survey, drawings, location schedules and additional investigations.
The project team should understand which penetrations have sufficient information for a repair to be specified and which remain subject to further assessment.
Responsibility for associated work should also be clear. If ceilings need to be opened, who reinstates them? If services obstruct the required installation, who coordinates the necessary alterations? How will changes to proposed details be reviewed and recorded?
These questions directly affect the quotations received.
If one contractor has allowed for opening up and reinstatement while another has priced only the visible sealing work, the figures are not directly comparable.
A lower quotation may reflect an efficient method, but it may also exclude work that another contractor has included. Comparing prices without understanding those differences can leave the client facing variations once the project begins.
Flame Stop’s building analysis, surveys and tender preparation services can assist clients and their appointed consultants in establishing a clearer scope before remediation works are procured.
Clear tender information will not eliminate every variation, particularly in older buildings. It can reduce avoidable assumptions and make the basis of each quotation easier to assess.
What Records Should You Receive After Fire Stopping Remediation?
Remediation records should reflect the work actually completed, including the locations treated, installation details and relevant supporting evidence. This information helps the client review the completed works and gives future maintenance teams a clearer understanding of the fire stopping already in place.
Photographs can be particularly useful where installations will be concealed behind ceilings, riser enclosures or wall finishes.
Location references, product information, installation records and appropriate completion documentation should be proportionate to the works and the project’s requirements.
Flame Stop operates an ISO 9001:2015 Quality Management System and uses industry-specific Boris software to monitor and record works in real time. Its project process includes providing post-contract documentation for clients’ operation and maintenance manuals.
These systems support the management and recording of works. They do not, by themselves, establish that an individual fire stopping installation complies with the applicable requirements.
The underlying installation must still be technically suitable and properly completed.
Years after handover, a facilities manager may need to introduce another service through a compartment wall. Knowing what was installed, where it was installed and how the original detail was formed can help avoid unnecessary disturbance or inappropriate alterations.
Documentation supports a suitable installation. It does not replace one.
How Does Fire Stopping Remediation Fit Within Irish Building Regulations?
Fire stopping remediation should be considered in the context of the applicable Building Regulations, the building’s fire strategy and the nature of the proposed works. The appropriate technical and statutory requirements depend on the building and the circumstances, so individual defects should not be assessed against a generic checklist alone.
Ireland’s Building Regulations set functional requirements for fire safety. The relevant Technical Guidance Document B provides guidance on ways the applicable requirements may be met.
The Department of Housing, Local Government and Heritage identifies Technical Guidance Document B 2024 – Fire Safety, Volume 1, Buildings Other than Dwelling Houses, including its 2026 reprinted edition. Volume 1 concerns buildings other than dwelling houses.
That does not mean the 2026 edition automatically governs every existing building or every historical installation.
The applicable requirements and guidance need to be considered in light of the building, the work being undertaken and any relevant transitional arrangements.
Existing buildings can be particularly difficult to assess because their original construction, subsequent alterations and available records may span different periods.
A remediation contractor should work from the relevant technical assessment and agreed scope. Responsibility for statutory compliance and professional certification remains with the appropriate parties under the applicable arrangements.
Where there is uncertainty about the building’s fire strategy or the suitability of a proposed solution, that uncertainty should be resolved before the work is treated as complete.
What Should an OMC or Facilities Manager Do After Receiving a Defect Report?
An OMC or facilities manager should establish the scope of the survey, arrange competent assessment of the findings and address any urgent concerns without waiting for the entire remediation programme to be developed. The remaining work can then be investigated, specified, procured and documented.
A practical sequence is:
- Confirm the survey scope. Establish which areas were inspected, which were inaccessible and what remains unknown.
- Assess priorities and precautions. Arrange competent review of the findings, including any urgent actions or interim precautions required.
- Define the repair scope. Investigate unresolved conditions and establish suitable remediation details for the affected construction and services.
- Procure and coordinate the work. Obtain comparable quotations and agree access, associated works, installation sequencing and responsibilities.
- Inspect and document completion. Arrange appropriate inspection, confirm the required records are available and complete the handover process.
The sequence should remain responsive to the findings. Necessary precautions or urgent works should not be delayed simply because investigations or tender preparation for the wider programme are still under way.

The figures also point to a changing demographic profile. The number of people aged 65 and over rose to 891,100, an increase of 165,000 since 2020. This age group now accounts for 16.1% of the population, reinforcing the growing need for accessible housing, healthcare facilities and age-friendly communities.
