Certified fire doorsets in Portsmouth, PO1

Certified fire doorsets for Portsmouth buildings

From the PO1 postcode district outwards, we take on certified fire doorsets across Portsmouth for homes, blocks and workplaces.

Fire doors in Portsmouth protect escape routes in schools, mixed-use office buildings and shared houses alike. We adapt the programme to the building and its occupants, never the standard of the installation.

Pre-hung doorsets keep disruption down in occupied buildings in Portsmouth, with less cutting and fewer return visits. Every doorset we fit in Portsmouth is handed over with its certificate reference and photographs of the frame fixing and gap sealing.

Why choose a doorset over a door leaf?

A fire door's rating belongs to the assembly that was tested, not to the leaf on its own. When a certified leaf is hung in an old frame with mismatched hinges and seals, nobody can say with confidence how it will perform. A doorset arrives with the frame, gaps and ironmongery already matched, so the installer's job is to fix it correctly into the opening and seal it to the structure.

Doorsets also cut time on site, which matters in occupied buildings: less cutting, less dust and fewer return visits.

On a typical job that means:

• Doorset selection to rating, size and use
• Installation to the manufacturer's instructions
• Pre-hung, pre-machined doorsets where available
• Frame fixing and frame-to-wall gap sealing

The regulations behind fire doors in Portsmouth

England's framework applies in Portsmouth. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.

For blocks over 11 metres in Portsmouth, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.

The need for certified fire doorsets usually arises in schools and offices or refurbishment programmes, and sometimes blocks of flats.
