Intumescent strips and smoke seals in North Watford: what's involved

Our intumescent strips and smoke seals service covers North Watford and the wider Hertfordshire area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.

Fire doors in North Watford protect escape routes in houses with integral garages, light industrial buildings 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 North Watford 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 North Watford we replace them with the type and size the certification specifies.

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.

As standard, the work covers:

• Removal of damaged or painted seals
• Intumescent pads to hinges and locks
• Check of gaps and closing after fitting
• Intumescent strips in frame or leaf edge

Fire door law for North Watford properties

In North Watford, 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.

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 North Watford 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.
