Fire Stopping Inspections
Independent inspections of penetration sealing and passive fire stopping, with detailed recommendations to restore compartmentation and reduce the spread of smoke and flames.
Independent Fire Stopping Inspections
Fire stopping is used to seal openings and penetrations within fire-resisting walls, floors and other compartment lines. Correctly installed systems help restrict the spread of fire and smoke and restore the fire resistance of construction disturbed by building services.
One Stop Consult works with an experienced specialist partner to carry out fire-stopping inspections. The survey reviews accessible areas of the building and identifies defects, missing protection, unsuitable products and breaches within compartmentation.
Following the inspection, detailed recommendations can be provided for the essential work required to improve compliance with the relevant fire strategy, drawings, product evidence and current guidance.
Maintaining Fire-Resisting Compartmentation
Openings created for pipes, cables, ducts and other services can weaken a fire-resisting wall or floor unless they are sealed with a suitable tested system.
Limit Fire Spread
Correct fire stopping helps delay fire from passing through openings between compartments.
Restrict Smoke Movement
Suitable sealing helps reduce smoke passing through gaps and service penetrations.
Protect Escape Routes
Compartmentation helps maintain protected corridors, stairs and escape routes during a fire.
Support Compliance
Inspection and remedial work can help the responsible person manage passive fire-protection duties.
What Does a Fire Stopping Inspection Cover?
The inspection reviews accessible fire-stopping installations and compartment lines. The precise scope depends on the building, access, available records and agreed survey level.
Areas hidden above ceilings, inside risers or behind finishes may require access panels, intrusive opening-up or specialist equipment before they can be assessed.
Issues Frequently Identified During Fire-Stopping Surveys
Defects often arise through incomplete installation, later service work or the use of products that are not suitable for the opening and construction.
Unsealed Penetrations
Pipes, cables or ducts may pass through fire-resisting construction without any suitable sealing.
Incomplete Seals
Gaps may remain around services or at the perimeter of an installed system.
Unsuitable Product Selection
A product may not be tested for the substrate, service type, opening size or required fire-resistance period.
Incorrect Installation Depth
Sealants, mortars and boards may not achieve the required thickness or support arrangement.
Damaged Fire Stopping
Existing systems may be broken, cut or disturbed by later building works.
Poorly Managed Service Changes
Additional cables or pipes may have been pushed through an existing seal without suitable reinstatement.
Missing Fire Collars or Wraps
Combustible pipes may lack the required intumescent protection.
Insufficient Evidence
Product labels, photographs, certification or installation records may be missing or unclear.
Your Fire Stopping Inspection Report
The report provides a structured record of the inspected areas, identified defects and recommended remedial works. Photographs and location references can help the building owner or contractor understand where action is required.
Recommendations may identify essential works required to restore compartmentation and may also include advisory improvements relating to labelling, access, records and ongoing fire-safety management.
The report can support discussions with the responsible person, fire risk assessor, fire engineer, Building Control body and competent remedial contractor.
Restoring Fire Compartmentation
Remedial work should use suitable tested systems installed in accordance with the product evidence and project-specific requirements.
Seal Open Penetrations
Install an appropriate tested fire-stopping system around the service and supporting construction.
Replace Defective Systems
Remove and replace damaged, unsupported or unsuitable installations.
Install Collars or Wraps
Provide suitable intumescent protection to combustible service pipes where required.
Improve Records and Labelling
Add identification labels and retain product, installation and photographic evidence.
How the Fire Stopping Inspection Process Works
Providing the available fire-safety records before the survey helps the inspector understand the intended compartmentation and inspection scope.
Document Review
Review plans, fire strategy, previous surveys and available installation records.
Site Inspection
Inspect accessible fire-stopping systems and compartment lines.
Defect Recording
Photograph and record missing, damaged or unsuitable systems.
Report Preparation
Prepare the schedule of findings and remedial recommendations.
Remedial Action
Appoint competent contractors to complete and document the required works.
Fire Stopping Inspections for a Range of Premises
Information Required for a Quotation
Provide the full property address, building use, number of storeys, approximate floor area and preferred inspection date.
Please also provide floor plans, fire strategy, compartmentation drawings, previous inspection reports and details of any known defects or recent service installations.

Important Fire Stopping Inspection Information
A fire-stopping inspection is generally a visual assessment of accessible areas unless an intrusive scope is expressly agreed. Concealed systems, hidden voids and inaccessible compartment lines may not be verified without opening-up. Final remedial specifications should consider the fire strategy, required fire-resistance period, substrate, service type, opening size and relevant product test evidence. A survey does not itself certify that every compartment line within the building is compliant. One Stop Consult provides consultancy and coordination support through its specialist passive fire-protection partner network.
Fire Stopping Inspection FAQs
What is fire stopping?
Fire stopping is the sealing of openings and joints within fire-resisting construction to help restrict the spread of fire and smoke.
Why are service penetrations a fire risk?
Pipes, cables and ducts create openings through compartment walls and floors. Without suitable sealing, fire and smoke can pass through them.
What does the inspection cover?
It can include penetrations, linear joints, collars, wraps, sealants, boards, dampers and other accessible passive fire-protection systems.
Is the survey intrusive?
Not necessarily. The standard scope is usually visual, but opening-up may be required to assess hidden or inaccessible areas.
Does the report include recommendations?
Yes. The report can identify essential works required to restore compartmentation and improve compliance.
Who should complete remedial fire stopping?
Remedial work should be completed by competent passive fire-protection contractors using suitable tested systems.
Can later service work damage fire stopping?
Yes. New cables, pipes and ducts can disturb existing systems unless the fire stopping is properly reinstated.
Is fire stopping the same as compartmentation?
Fire stopping is one part of compartmentation. Compartmentation also includes walls, floors, doors, glazing, dampers and other fire-resisting elements.
What information is needed for a quotation?
Provide the address, building use, floor area, plans, fire strategy, compartmentation drawings and any previous reports.
