Intumescent strips and smoke seals for Derby buildings
From the DE1 postcode district outwards, we take on intumescent strips and smoke seals across Derby for homes, blocks and workplaces.
In and around Derby, fire door work covers everything from converted flats to schools. We plan each job around the people who use the building.
Painted and missing seals are among the most common fire door defects nationally; in Derby we replace them with the type and size the certification specifies. We check that each door in your Derby building closes and latches against its new seals before signing it off.
Pads, linings and hidden protection
Fire doors also rely on intumescent material you cannot see: pads behind hinges, linings around lock bodies and glazing seals. Where these are missing or damaged, we fit the correct items as part of the work.
What you get:
- Intumescent pads to hinges and locks
- Brush or blade smoke seals
- Check of gaps and closing after fitting
- Identification of the specified seals
Which fire door rules apply in Derby?
Fire doors in Derby 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 Derby 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.

Common questions
Do you cover DE1 and nearby postcodes?
Yes. We cover Derby including DE1, and nearby towns such as Belper and Ilkeston. The survey and written quote are free.
What happens on a survey in Derby?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
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.
How long do seals last?
It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.
