Fire Door Surveys

Fire Door Surveys and
Compartmentation Assessments

Compartmentation is the thing nobody thinks about until it matters most.

Fire doors and compartmentation are quiet workers — you only notice them if they fail. We provide expert fire door and compartmentation surveys to keep your building safe, compliant, and properly protected.

A fire door only earns its place in a building’s fire safety strategy if it actually works when it’s needed. Our fire door surveys are a detailed inspection of every fire door in a building, checking they’re fit for purpose and compliant with current fire safety regulations.

Fire doors are a critical component of a building’s passive fire protection system. They help prevent the spread of fire and smoke, providing safe escape routes for occupants and minimising damage to property.

During a fire, properly functioning fire doors compartmentalise the building, slowing the spread of flames and smoke and giving occupants more time to evacuate safely. If fire doors are damaged, improperly installed, or not maintained, they may fail in an emergency, putting lives and property at serious risk.

During the survey, we will:

Inspect the door and frame: Look for any cracks, damage, or defects that could weaken the door’s fire resistance.
Check installation: Verify that each door is correctly fitted and aligned within its frame to perform as designed.
Look for wear and damage: Identify issues like warped doors, holes, missing panels, or signs of misuse.
Assess door hardware: Examine hinges, locks, door closers, smoke seals, and intumescent strips to ensure they are present, functional, and properly maintained.
Test door operation: Make sure the doors close and latch fully without obstruction, as a door left open or poorly closed cannot protect against fire or smoke.
Identify unauthorised modifications: Detect any changes or damage that could reduce the fire door’s effectiveness, such as drilled holes, incorrect handles, or missing components.

Following each survey, we provide a clear, practical report outlining any faults or issues, complete with recommendations for repair, replacement, or maintenance. This helps you stay compliant and avoid costly penalties or insurance issues.

Compartmentation Assessments

Compartmentation is what stops a fire in one flat becoming a fire in the whole building. We inspect the internal structure of your building, walls, floors, ceilings, risers, and service penetrations, to make sure fire and smoke can’t travel freely through gaps or breaches. We also review fire stopping and sealing around pipes, cables, and ducts.

Effective compartmentation buys people the time they need to escape. It’s also a legal requirement under fire safety regulations — and if it’s compromised, a single breach can let fire move quickly between areas that should have been sealed off from each other.

Our assessments find the weak points before they’re tested for real, so you get a clear plan to bring compartmentation up to standard — protecting both the people in the building, and its future.

Our compartmentation surveys focus on the critical areas that prevent fire and smoke from spreading through a building, including:

Examine compartment walls, ceilings, and floors: Check for signs of wear, damage, or deterioration that could compromise fire resistance.
Identify gaps and breaches: Locate any unsealed openings or breaks in compartment lines where fire or smoke could travel.
Assess service penetrations: Review areas around cables, ducts, and pipes to ensure they’re correctly sealed with approved fire-stopping methods.
Evaluate fire-stopping materials: Confirm the use of appropriate, certified materials installed to required standards.
Record findings clearly: Capture all issues with supporting photos and notes for accurate reporting and follow-up.
Recommend corrective actions: Provide a prioritised list of remedial works needed to restore effective fire separation and meet safety requirements.

Why are Fire Door Surveys and Compartmentation
Assessments important?

Fire doors and compartmentation work together to buy time — time for someone to get out safely. These aren’t just best practice; they’re legal requirements under UK fire safety laws, including the Regulatory Reform (Fire Safety) Order 2005.

Whoever is responsible for fire safety in a building has to make sure fire doors are properly assessed as part of the wider fire risk evaluation. Yet many assessments only check a sample of doors — which can miss the faults that matter most: gaps, damaged seals, incorrect installations. That’s why we look in depth, not just at a sample.

You shouldn’t have to wait for a fire to find out whether your protection actually works.

FAQs

What is a fire door survey?

A fire door survey is a detailed inspection of fire doors throughout a building to assess their condition, compliance, and effectiveness in preventing the spread of fire and smoke. The survey checks for proper installation, certification, gaps, seals, hardware, and maintenance needs.

Why are fire door surveys important?

Fire doors are critical life-safety features designed to hold back fire and smoke, protecting escape routes and giving occupants time to evacuate. Regular surveys ensure that doors function as intended and meet current fire safety regulations, especially under the Fire Safety (England) Regulations 2022.

What is a compartmentation assessment?

A compartmentation assessment evaluates the fire-resisting construction within a building, such as walls, floors, ceilings, and service risers, to ensure they effectively contain fire and smoke within defined areas. This helps limit fire spread and supports safe evacuation.

When should these assessments be carried out?

At regular intervals (e.g. annually for fire doors in high-rise residential buildings); after any refurbishment or structural alterations; when there are concerns about fire safety or previous poor workmanship; and to support fire risk assessments or regulatory compliance.

Who can carry out these assessments?

Only competent and qualified fire safety professionals should conduct these surveys. At Buildtech Consultancy, our assessors are fully trained and accredited to inspect fire doors and passive fire protection systems in line with current British Standards and regulatory guidance.

What does a fire door survey include?

A typical survey checks certification and correct installation; intact frames and seals; door leaf and frame gaps; functionality of hinges, closers, and latches; and signs of wear, damage, or non-compliant modifications. Findings are compiled into a detailed report with photographic evidence and recommendations.

What does a compartmentation assessment involve?

It includes visual inspections of accessible areas (service risers, plant rooms, ceiling voids); identification of breaches, poor workmanship, or non-compliant firestopping; documentation of passive fire protection systems (fire-rated walls, ductwork penetrations); and recommendations for remedial actions. Intrusive inspections may be necessary in certain cases.

Are fire door surveys and compartmentation assessments a legal requirement?

Yes, they form part of a building’s fire risk assessment duties under the Regulatory Reform (Fire Safety) Order 2005 and the Fire Safety Act 2021. For multi-occupied residential buildings, regular fire door checks are now mandatory under the Fire Safety (England) Regulations 2022.

What happens after the survey or assessment?

You’ll receive a comprehensive report detailing all non-compliances, photographs of findings, risk ratings, and clear recommendations. Buildtech Consultancy can also assist with remedial works to ensure full compliance with fire safety regulations.
