Fire Stopping Services in Hampshire & Surrey

Lockmasters deliver certified fire stopping installation, surveys, and remedial works to commercial, residential, education, and healthcare clients across Hampshire and Surrey. With over 30 years' experience in building security and fire safety, our qualified operatives work to the requirements of the Regulatory Reform (Fire Safety) Order 2005 and the Building Safety Act 2022, providing a fully documented, certification-backed passive fire protection service throughout Farnham, Guildford, Basingstoke, Fleet, Camberley, Farnborough, Aldershot, and all surrounding areas.

Fire stopping is a legal requirement, not an optional extra. Breaches in fire compartmentation, even small, seemingly minor gaps can allow fire and toxic smoke to spread rapidly through a building. Whether you manage a commercial property, a school, a care facility, or a residential block, maintaining intact fire stopping is a fundamental part of your fire safety obligations.

BMTrada Q-Mark Certified Fire Stopping Installation

Our fire stopping installations are carried out under the BMTrada Q-Mark scheme, providing independent, verifiable evidence that work is completed to the highest standard. The certification covers all penetration types and linear gaps in fire-rated walls and floors across Hampshire and Surrey. Every installation is completed strictly in accordance with tested system details by operatives who have been trained and assessed under our Q-Mark certification.

On completion you receive a full documentation pack including photographic evidence, product data sheets, and scheme certification, giving you a complete audit trail for your building's passive fire protection records.

What’s included:

• Pipe and cable penetration seals

• Duct and services penetrations

• Linear gap seals at wall and floor junctions

• Structural movement joints

• Intumescent products and fire-rated sealants

• Full project management from survey to handover

Choosing a Q-Mark certified contractor for fire stopping means your compliance audit trail holds up to scrutiny whether that's for a fire safety audit, an insurance claim, or the requirements of the Building Safety Act 2022. It also ensures that correct, tested products and installation methods are used throughout. Our fire stopping work sits alongside our BMTrada Q-Mark certified fire door installation service, giving you a single, certified contractor for your building's passive fire protection needs.

Fire Stopping Surveys & Inspections

Regular fire stopping surveys are essential to ensure your building's compartmentation remains intact and compliant. Breaches caused by service installations, building works, or deterioration are among the most common fire safety deficiencies identified in commercial and residential properties across Hampshire and Surrey and they are often invisible to the untrained eye.

Our qualified surveyors carry out thorough assessments of penetrations and linear gaps throughout your building, providing a clear, prioritised report on any deficiencies found. Surveys are suitable for landlords, building owners, facilities managers, managing agents, and responsible persons under the Regulatory Reform (Fire Safety) Order 2005.

What’s included:

• Intrusive and non-intrusive survey options

• Full building or targeted area surveys

• Identification and recording of all penetrations

• Condition assessment of existing fire stopping

• Prioritised remedial works schedule

• Compliance reporting for landlords, building owners, and managing agents

Surveys are recommended following any building or maintenance works affecting fire-rated elements, and as part of routine fire safety assessments, typically annually for most buildings and more frequently for higher-risk premises.

Remedial Fire Stopping Works

Where existing fire stopping has failed, been breached, or was never correctly installed, our operatives carry out remedial works using Q-Mark accepted products and techniques, restoring your building's compartmentation to a compliant standard. Unsealed penetrations left by other trades are one of the most common findings during fire stopping surveys, a problem we encounter regularly across commercial and residential properties throughout Hampshire and Surrey.

All remedial fire stopping works are fully documented with before, during, and after photographic evidence, providing a clear record of what was found and what was done.

What’s included:

• Removal and replacement of failed or missing seals

• Remediation of service penetrations left unsealed by other trades

• Upgrading of legacy fire stopping to current standards

• Q-Mark labelling and full documentation on completion

Your Fire Door Documentation & Certification Pack

Every fire stopping project is supported by comprehensive documentation, ensuring you have a complete record for compliance, insurance, and safety management purposes.

Documentation includes:

• Pre-installation or condition survey records

• Record of installation or maintenance activities

• Photographic evidence (before, during, and after)

• Product data sheets and traceability records

• Q-Mark certification on completion

• Full documentation pack for your records

For buildings within scope of the Building Safety Act 2022 including higher-risk residential buildings of 18 metres or more fire stopping documentation forms part of the required golden thread of building information. Lockmasters provides a complete, audit-ready documentation pack on every project to support these requirements.
