Intumescent strip and smoke seal fitting in London

Intumescent strips and smoke seals in London, done to the evidence

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

Around London, shared houses, clinics and schools 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.

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

Why seals fail

Seals are the most common defect on fire door inspections. They get painted over, pulled out, damaged by cleaning or simply worn by years of use. A painted brush seal no longer seals, and a strip of the wrong size may not close the gap in a fire. Our guide to seals explains the different types.

What you get:

• Check of gaps and closing after fitting
• Intumescent pads to hinges and locks
• Identification of the specified seals
• Brush or blade smoke seals

Which fire door rules apply in London?

In 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 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 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.
