FD30 fire doors for Isleworth buildings
Our FD30 fire doors service in Isleworth is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.
Around Isleworth, clinics, hotels and care homes all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
For a mixed portfolio in Isleworth, we can survey every FD30 opening in one visit and price leaf-only and doorset options side by side. Each FD30 leaf we supply for Isleworth is sized for the opening, rather than trimmed beyond what its certification allows.
What does a correct FD30 installation include?
A typical timber FD30 leaf is around 44mm thick and hangs on at least three fire-tested hinges. The gaps between leaf and frame are set to the manufacturer's data, usually around 3mm. Intumescent strips, and smoke seals where needed, go in the frame or leaf edge as specified. The closer must pull the door shut and latch it from any angle. Every hole cut for a lock, latch or hinge is lined with intumescent material where the certification calls for it.
Then comes the part that is often skipped: sealing the gap between the frame and the wall with a tested material, as BS 8214:2026 now sets out in more detail.
Each installation includes:
- Fire-tested hinges, latch or lock and intumescent pads
- Survey of the opening, frame and existing ironmongery
- Certified FD30 or FD30S leaf, or full doorset
- Frame-to-wall gap sealed with an evidenced material
Fire door law for Isleworth properties
Fire doors in Isleworth fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained. In London, the London Fire Brigade is the enforcing authority for fire safety law.
For residential buildings in Isleworth above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Common questions
Is Isleworth within your coverage area?
It is. We cover Isleworth in Greater London and neighbouring towns such as Hounslow. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
How long does it take to fit an FD30 door?
A leaf into a sound frame is often a few hours. A full doorset including frame removal, fixing, sealing and making good is usually half a day to a day per opening, depending on access and the wall construction.
Can a new FD30 door go into my old frame?
Sometimes. The frame has to be sound, square, securely fixed and compatible with the new leaf's certification. Many older frames are not, especially softwood linings or frames altered for previous doors. We check each frame on the survey and recommend a doorset only where the frame cannot be relied on.
