Our Fire Stopping Services
Mitie provides a complete lifecycle approach to fire system installation, inspection and remediation — helping ensure compartment lines remain protected and compliant.
- Compartmentation Surveys
Buildings change over time, and service upgrades or refurbishment works can leave penetrations unsealed, so our surveys identify breaches, damaged fire stopping, non-compliant materials and priority remedial risks.
- Certified Fire Stopping Installation
Our accredited teams deliver comprehensive installations using tested, approved systems, ensuring correct product selection, compatibility with substrates and services, accurate fire rating restoration and full documentation.
- Remedial Fire Stopping Works
Where deficiencies are identified, we deliver structured remedial programmes that restore compartment integrity, replace non-compliant materials, upgrade historic installations and align systems with current fire strategy requirements.

FAQs: Fire Stopping
Why is fire stopping important?
Without correct fire stopping, fire and smoke can travel rapidly through buildings via service voids and penetrations, compromising compartmentation and escape routes.
Who can carry out fire stopping installation?
Fire stopping installation should be completed by competent, accredited fire stopping contractors operating under recognised third-party certification schemes such as FIRAS or BM TRADA Q-Mark (or equivalent).
How often should fire stopping be inspected?
Fire stopping should be inspected regularly, particularly after refurbishment or service installation works that may have created new penetrations in fire-rated barriers.
What is a compartmentation survey?
A compartmentation survey assesses the integrity of fire-rated walls and floors, identifying breaches and deficiencies in fire stopping systems that may compromise fire safety.
How do I know if my fire stopping is compliant?
Compliance requires installation in line with tested specifications, third-party certification evidence, documented surveys and structured remedial tracking. A professional survey provides clear visibility of current risk.
