Fire Door Installation
Precision-engineered fire door fitting services to provide robust passive fire protection and guaranteed structural integrity for your property.
Service Overview
At Greensurv, we provide expert fire door installation services that go far beyond standard carpentry. A fire door is a life-saving system, and its effectiveness depends entirely on the precision of its installation. Even the highest-rated FD60 door will fail to protect occupants if the frame is poorly fitted or the intumescent seals are compromised. Our team of certified installers specializes in the bespoke fitting of fire-rated timber and composite doors for commercial, industrial, and multi-tenant residential buildings. We ensure that every installation meets the strict requirements of the Regulatory Reform (Fire Safety) Order 2005 and BS 8214 standards. From sourcing BM TRADA Q-Mark certified doors to ensuring millimetre-perfect clearances, Greensurv delivers a "fit-and-forget" solution that guarantees safety and legal compliance from day one.
Certified Door Set & Frame Fitting
The core of our service is the seamless integration of the door leaf with its dedicated frame. We ensure that the structural opening is correctly prepared and that the fire door set functions as a singular, smoke-tight barrier.
Providing FD30 and FD60 rated doors in various finishes to match your building’s interior design.
Ensuring the frame is perfectly square and plumb to prevent future warping or binding.
Using certified fire-stopping foam or mineral wool to seal the gap between the door frame and the wall.
Expertly fitting heat-sensitive seals that expand during a fire to block the passage of lethal smoke.
Modifying or reinforcing existing walls to ensure they can support the weight and fire-rating of a new door set.
Specialized Hardware & Closing Systems
A fire door must be "self-closing" to be effective. We install high-grade, fire-certified ironmongery that ensures your doors remain closed during an emergency while allowing easy egress for occupants during normal operations.
Installing overhead or concealed closers that are power-adjusted for the specific weight of the door.
Fitting CE-marked, grade 13 hinges that can withstand the intense heat of a localized fire.
Ensuring the latch engages smoothly every time the door closes, maintaining the door's position under pressure.
Adding high-performance seals to minimize the transfer of sound and toxic cool smoke between compartments.
Installing "Panic Bars" or "Push Pads" for high-traffic escape routes that require immediate release.

Frequently Asked Questions
Can I use a standard door closer on a fire door?
No. Fire doors must use "fire-rated" closers that have been tested to maintain their strength and function under extreme temperatures.
Is it okay to trim a fire door to fit a frame?
Fire doors can only be trimmed within very strict limits (usually 3mm–5mm) specified by the manufacturer. Over-trimming can void the fire certification.
Do you install fire doors in residential flats?
Yes, we specialize in installing "Flat Entrance Doors" that meet the latest 2022 Fire Safety Regulations for multi-occupied buildings.
How long does it take to install a single fire door?
On average, a professional installation of a complete fire door set takes between 3 to 5 hours, including fire-stopping and hardware calibration.
What is the "Certification Tag" on the door?
Every door we install has a plastic "plug" or label on the top or hinge edge. This is the manufacturer's proof of fire rating and should never be removed.
