Intumescent strip and smoke seal fitting in Carshalton

Intumescent strips and smoke seals: our service in Carshalton

Our intumescent strips and smoke seals service in Carshalton is simple: a survey, a fixed quote, certified products and an installation finished to the manufacturer's evidence.

Fire doors in Carshalton protect escape routes in mixed-use office buildings, student accommodation and care homes alike. We adapt the programme to the building and its occupants, never the standard of the installation.

We check that each door in your Carshalton 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 Carshalton we replace them with the type and size the certification specifies.

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.

On a typical job that means:

• Intumescent pads to hinges and locks
• Brush or blade smoke seals
• Removal of damaged or painted seals
• Identification of the specified seals

Which fire door rules apply in Carshalton?

In Carshalton, 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. In London, the London Fire Brigade is the enforcing authority for fire safety law.

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 Carshalton 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.
