Intumescent strips and smoke seals in Barnet, EN5

Getting intumescent strips and smoke seals right in Barnet

Our intumescent strips and smoke seals service covers Barnet 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.

Fire doors in Barnet protect escape routes in restaurants, mixed-use office buildings and hotels alike. We adapt the programme to the building and its occupants, never the standard of the installation.

Painted and missing seals are among the most common fire door defects nationally; in Barnet we replace them with the type and size the certification specifies. Seal replacement in Barnet can be combined with any other remedials on the same inspection report.

Getting the specification right

The door's certification states the type, size and position of strips and seals: in the frame or the leaf edge, single or double, and whether a combined intumescent and smoke seal is used. Replacements must match. Swapping in a generic strip from a hardware shop can undermine the door's performance.

Each installation includes:

• Identification of the specified seals
• Intumescent strips in frame or leaf edge
• Brush or blade smoke seals
• Intumescent pads to hinges and locks

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. Enforcement of fire safety law in Barnet sits with the London Fire Brigade.

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.
