Intumescent strips and smoke seals across Greater London

What intumescent strips and smoke seals in Greater London should include

We provide intumescent strips and smoke seals across Greater London, covering 82 towns and 279 postcode districts, including London, Islington and City of Westminster.

We check that each door in your Greater London building closes and latches against its new seals before signing it off. Painted and missing seals are among the most common fire door defects nationally; in Greater London we replace them with the type and size the certification specifies.

Fire door work in Greater London spans housing providers with large estates, individual landlords, businesses and homeowners. We price every job from a survey, never from a list price alone, because the condition of the frames and the hardware makes a real difference.

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.

What the rules say for Greater London

In Greater London, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet. Enforcement of fire safety law in Greater London sits with the London Fire Brigade.

Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Greater London building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.
