Intumescent strips and smoke seals: our service in Billingham
Our intumescent strips and smoke seals service covers Billingham and the wider County Durham area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
In and around Billingham, fire door work covers everything from care homes to schools. We plan each job around the people who use the building.
Seal replacement in Billingham can be combined with any other remedials on the same inspection report. We check that each door in your Billingham building closes and latches against its new seals before signing it off.
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:
- Brush or blade smoke seals
- Identification of the specified seals
- Intumescent strips in frame or leaf edge
- Intumescent pads to hinges and locks
Rules and responsibilities in Billingham
Fire doors in Billingham 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 Billingham 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 Billingham
Is Billingham within your coverage area?
It is. We cover Billingham in County Durham and neighbouring towns such as Stockton-on-Tees. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
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.
