Intumescent strips and smoke seals: our service in Alfreton
Looking for intumescent strips and smoke seals in Alfreton? We supply and fit certified fire doors and components across Alfreton and the wider Derbyshire area, working from a free survey and a fixed written quote.
In and around Alfreton, fire door work covers everything from care homes to houses with integral garages. We plan each job around the people who use the building.
We check that each door in your Alfreton 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 Alfreton 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.
As standard, the work covers:
- Intumescent pads to hinges and locks
- Brush or blade smoke seals
- Identification of the specified seals
- Check of gaps and closing after fitting
Fire door law for Alfreton properties
Fire doors in Alfreton fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.
For residential buildings in Alfreton above 11 metres, regulation 10 of the Fire Safety (England) Regulations 2022 adds checks: communal fire doors at least every three months and best-endeavours checks of flat entrance doors at least every twelve months. Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Questions from Alfreton
Do you cover DE55 and nearby postcodes?
Yes. We cover Alfreton including DE55, and nearby towns such as Ripley and Sutton in Ashfield. The survey and written quote are free.
How quickly can you survey in Alfreton?
It depends on the number of doors and access, but we offer survey dates as soon as we reply to your enquiry. If an inspection has found urgent safety issues, tell us and we'll prioritise.
Can I just add intumescent strips to an ordinary door?
No. Strips do not turn an ordinary door into a fire door. They only work as part of a door that was tested and certified with them.
Do all fire doors need smoke seals?
Only where the door is specified for smoke control, such as FD30S doors. Many doors on escape routes and flat entrances are specified this way.
