Intumescent strips and smoke seals for Hemel Hempstead buildings
If you need intumescent strips and smoke seals in Hemel Hempstead, we can survey, supply and install, then leave you the evidence your fire risk assessor will ask for.
Buildings in and around Hemel Hempstead range from HMOs to care homes and houses with integral garages. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Seal replacement in Hemel Hempstead can be combined with any other remedials on the same inspection report. We check that each door in your Hemel Hempstead building closes and latches against its new seals before signing it off.
Why seals fail
Seals are the most common defect on fire door inspections. They get painted over, pulled out, damaged by cleaning or simply worn by years of use. A painted brush seal no longer seals, and a strip of the wrong size may not close the gap in a fire. Our guide to seals explains the different types.
Each installation includes:
- Removal of damaged or painted seals
- Intumescent pads to hinges and locks
- Identification of the specified seals
- Brush or blade smoke seals
Rules and responsibilities in Hemel Hempstead
In Hemel Hempstead, 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 Hemel Hempstead 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.

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.

It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.
