Intumescent strip and smoke seal fitting in Northamptonshire

Intumescent strips and smoke seals for Northamptonshire buildings

We provide intumescent strips and smoke seals across Northamptonshire, covering 7 towns and 23 postcode districts, including Northampton, Corby and Kettering.

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

Wherever your building is in Northamptonshire, the fire safety duties come from national rules, and our installation standard is the same.

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.

Which fire door rules apply in Northamptonshire?

In Northamptonshire, 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 Northamptonshire 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.
