Intumescent strips and smoke seals: our service in Swanley
For property owners, landlords and managing agents in Swanley, we offer intumescent strips and smoke seals with one team for the survey, the product and the installation.
Buildings in and around Swanley range from light industrial buildings to care homes and family homes after loft conversions. 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 Swanley can be combined with any other remedials on the same inspection report. We check that each door in your Swanley 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:
- Check of gaps and closing after fitting
- Identification of the specified seals
- Removal of damaged or painted seals
- Brush or blade smoke seals
The regulations behind fire doors in Swanley
Fire doors in Swanley 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 Swanley 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
Do you work in Swanley?
Yes, we take on intumescent strips and smoke seals in Swanley and the surrounding area, including Bexley and Dartford. Send your postcode and a few details and we'll come back with survey dates.
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.
