Intumescent strips and smoke seals: our service in Islington
Our intumescent strips and smoke seals service covers Islington and the wider Greater London area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
In and around Islington, fire door work covers everything from hotels to purpose-built blocks of flats. We plan each job around the people who use the building.
Painted and missing seals are among the most common fire door defects nationally; in Islington we replace them with the type and size the certification specifies. We check that each door in your Islington building closes and latches against its new seals before signing it off.
Pads, linings and hidden protection
Fire doors also rely on intumescent material you cannot see: pads behind hinges, linings around lock bodies and glazing seals. Where these are missing or damaged, we fit the correct items as part of the work.
Each installation includes:
- Removal of damaged or painted seals
- Identification of the specified seals
- Brush or blade smoke seals
- Intumescent pads to hinges and locks
Rules and responsibilities in Islington
England's framework applies in Islington. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors. Enforcement of fire safety law in Islington sits with the London Fire Brigade.
For blocks over 11 metres in Islington, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.
Which buildings in Islington need intumescent strips and smoke seals?
From blocks of flats to HMOs, the requirement for intumescent strips and smoke seals in Islington comes from the fire strategy or risk assessment for the building. We work from that document, or help you interpret your inspection report, before quoting.

Common questions
Do you cover N1 and nearby postcodes?
Yes. We cover Islington including N1, and nearby towns such as Highbury and Holloway. The survey and written quote are free.
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.
Can I just add intumescent strips to an ordinary door?
No. Strips do not turn an ordinary door into a fire door. They only work as part of a door that was tested and certified with them.
Do all fire doors need smoke seals?
Only where the door is specified for smoke control, such as FD30S doors. Many doors on escape routes and flat entrances are specified this way.
