Fire stopping is a critical part of a building’s passive fire protection strategy. It is designed to prevent fire, smoke and toxic gases from spreading through a building via gaps, joints and service penetrations — helping to protect escape routes, reduce damage and save lives.

Our professional fire stopping services ensure that fire compartmentation is correctly installed, maintained and restored in line with UK legislation and recognised standards.

What Is Fire Stopping?

Fire stopping involves sealing openings and joints created by services such as:

• Electrical cabling

• Pipework and ductwork

• Data and communication services

• Structural movement joints

• Wall, floor and ceiling penetrations

Without effective fire stopping, fire and smoke can spread rapidly between compartments, undermining the building’s fire resistance and evacuation strategy.

Why Fire Stopping Is Essential

Even small unsealed gaps can allow fire and smoke to spread far quicker than intended. Correct fire stopping helps to:

• Maintain fire-resistant compartmentation

• Protect escape routes and stairwells

• Limit smoke and toxic gas spread

• Support safe evacuation and firefighting operations

• Meet legal and insurance requirements

Poor or missing fire stopping is a common cause of non-compliance identified during fire risk assessments and audits.

Our Fire Stopping Services

We provide a full range of passive fire protection and fire stopping solutions, carried out by competent, trained technicians. Services include:

• Fire stopping of service penetrations

• Sealing of linear joints and construction gaps

• Installation of fire collars, wraps and sleeves

• Fire-resistant mastic, sealants and batt systems

• Upgrading or remediation of defective fire stopping

• Fire stopping following refurbishments or building works

All works are completed using tested and certified systems, installed in accordance with manufacturer instructions and fire-resistance requirements.

Compliance & Legal Responsibilities

Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must ensure that fire precautions — including passive fire protection — are properly installed and maintained.

Fire stopping works are also aligned with relevant British Standards and building regulations, and failures can result in enforcement action, increased risk to life, and invalidated insurance cover.

Inspection, Remediation & Documentation

Fire stopping should be inspected regularly as part of fire risk assessments and passive fire surveys. Where defects are identified, prompt remedial work is essential.

We provide:

• Clear identification of non-compliant fire stopping

• Professional remedial solutions

• Photographic evidence (before and after)

• Certification and records to support compliance and audits
