Fire Door Inspections
Professional safety audits to ensure your fire doors provide a critical life-saving barrier against the spread of smoke and flames.
Service Overview
At Greensurv, we recognize that a fire door is much more than just a piece of timber; it is a complex engineered safety device. In the event of a fire, the integrity of your fire doors can be the difference between a minor incident and a catastrophic tragedy. Under the latest Fire Safety (England) Regulations 2022, it is now a legal requirement for responsible persons of multi-occupied residential buildings to conduct regular checks on fire doors. Our certified inspectors provide detailed, non-destructive surveys to ensure that every component—from the leaf and frame to the intumescent seals and closing mechanisms—is fully functional and compliant with UK safety standards. Whether it’s an annual check for a commercial office or quarterly inspections for high-rise domestic blocks, Greensurv provides the technical expertise to keep your "passive fire protection" systems intact.
Detailed Component Integrity Assessment
A fire door only works if every single part of it performs under heat. Our inspectors conduct a point-by-point physical check of the door’s construction to identify any wear, tear, or unauthorized modifications that could lead to a failure during a fire.
Checking for warping, bowing, or damage that prevents the door from fitting snugly into its frame
Verifying that heat-sensitive strips are present, undamaged, and correctly fitted to expand and seal gaps.
Ensuring fire-rated glass is securely fitted with the correct non-combustible beads and gaskets.
Using precision gauges to ensure the gaps between the door and frame do not exceed the 3mm-4mm safety limit.
Checking that the gap at the bottom of the door is sufficient for air movement but tight enough to block smoke.
Hardware Functionality and Closing Mechanism Checks
Even the best fire door is useless if it doesn't close properly or stay shut. We test the "ironmongery" and self-closing devices to ensure the door performs its primary function: automatically creating a sealed compartment when a fire alarm sounds.
Verifying that the door closes reliably from any angle and overcomes the resistance of the latch and seals.
Checking that all hinges are CE-marked, securely fixed, and free from oil leaks or metal fragments
Ensuring the door latches securely without needing to be forced, maintaining the door’s position during high pressure.
Checking brush or fin seals for damage that could allow toxic cool smoke to bypass the door in the early stages of a fire
Confirming that "Fire Door Keep Shut" or "Fire Door Keep Locked" signs are visible and correctly placed.

Our Process
STEP 01
Door Schedule Creation
At Greensurv, we start by mapping out every fire door in your building, assigning a unique ID to each for easy tracking and future maintenance.
STEP 02
Multi-Point Physical Inspection
Our inspector tests every mechanical element, measures gaps, and checks the certification tags on the door edges to verify its fire rating (e.g., FD30 or FD60).
STEP 03
Defect Identification & Categorization
Any issues found are photographed and graded by risk level, from minor maintenance (adjustments) to critical failures (replacement needed).
STEP 04
Compliance Report Delivery
You are issued a professional report for your Fire Safety Log Book, including a clear list of recommendations to bring any non-compliant doors back to standard.
Frequently Asked Questions
How often do fire doors need to be inspected?
For residential buildings over 11 meters, communal fire doors must be checked every 3 months, and flat entrance doors annually. Commercial buildings typically require an annual inspection.
What is an FD30 and FD60 door?
FD30 provides 30 minutes of fire resistance, while FD60 provides 60 minutes. Our inspection verifies if the door installed matches the requirement for that specific location.
Can a fire door be repaired, or must it be replaced?
Many issues, like faulty closers or damaged seals, can be repaired by a competent joiner. However, if the door leaf is heavily warped or the frame is split, a replacement is usually necessary.
Why is the 3mm gap so important?
If the gap is too large, the intumescent seal cannot expand far enough to bridge the space, allowing fire and smoke to pour through the edges of the door.
Do you provide the repairs as well?
At Greensurv, we provide independent inspections to give you an unbiased report. We can, however, recommend trusted specialists to carry out any necessary remedial works.
