Fire Stopping Services — Sealed to Spec, Documented on Completion
Penetration Sealing
Sealing around pipes, cables, trays and duct penetrations through fire-rated walls and floors. Every breach is made good with the correct tested system for the substrate and service type, restoring the compartment line.
Fire Batts & Sealant
Fire batt installation to larger openings and service risers, with intumescent and acoustic sealant to linear gaps and joints — installed to manufacturer specification and recorded for your compliance file.
Fire Collars & Wraps
Intumescent collars and wraps fitted to plastic pipes and ducts that would otherwise soften and breach the compartment in a fire — matched to pipe diameter, material and wall or floor build-up.
Compartmentation Surveys & FRA Remedials
Surveys of walls, floors, risers and voids to identify breaches — plus remedial works packages that close out actions raised in your fire risk assessment, with before-and-after evidence for your records.
Why Compartmentation Matters
A building's fire strategy assumes every compartment wall and floor actually holds. One unsealed penetration can undermine the lot.
The Risk of Unsealed Breaches
Every unsealed pipe run, cable route or riser opening lets smoke and fire bypass the compartment line. These breaches are routinely flagged in fire risk assessments — and leaving FRA actions open can lead to enforcement action against the responsible person.
What We Handle For You
We survey, seal and document — penetrations, gaps, batts, collars and linear joints, using tested systems installed to manufacturer specification. Combined with our fire door work, most passive fire protection actions on an FRA can be closed out by one contractor.
Simple Process. Clear Records.

Who We Work With
Landlords & HMO Operators
Close out fire risk assessment actions on flats, HMOs and converted properties — alongside fire door work where needed, from one contractor.
Housing Associations & Councils
Compartmentation surveys and planned remedial programmes across blocks and portfolios, with the documentation your compliance team needs.
Facilities & Property Managers
Reactive and planned fire stopping across commercial buildings — risers, ceiling voids, plant rooms and service routes.
Main Contractors & Fit-Out Teams
Fire stopping packages on refurbishments and fit-outs — penetrations sealed as services go in, not patched up after handover.
Fire doors + fire stopping
One Contractor for Your Passive Fire Protection
Fire doors and fire stopping are the two passive fire measures most often flagged in fire risk assessments. We carry out both — surveys, installation and remedial works under one contract, with documentation on completion.
