Intumescent strips and smoke seals in Sudbury, done to the evidence
We provide intumescent strips and smoke seals in Sudbury (CO10 and the surrounding postcodes), from the first survey through to a documented handover.
Sudbury has a broad mix of buildings, including small blocks of flats, houses with integral garages and family homes after loft conversions, and the same fire door principles apply to all of them.
We check that each door in your Sudbury 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 Sudbury we replace them with the type and size the certification specifies.
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:
- Identification of the specified seals
- Check of gaps and closing after fitting
- Intumescent strips in frame or leaf edge
- Brush or blade smoke seals
What the rules say for Sudbury
In Sudbury, 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 Sudbury 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.

Questions
Is Sudbury within your coverage area?
It is. We cover Sudbury in Suffolk and neighbouring towns such as Colchester. 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.
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.
