Intumescent strips and smoke seals for Derry buildings
For property owners, landlords and managing agents in Derry, we offer intumescent strips and smoke seals with one team for the survey, the product and the installation.
Fire doors in Derry protect escape routes in schools, low-rise blocks of flats and high-street shops alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Painted and missing seals are among the most common fire door defects nationally; in Derry we replace them with the type and size the certification specifies. Seal replacement in Derry can be combined with any other remedials on the same inspection report.
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.
On a typical job that means:
- Brush or blade smoke seals
- Identification of the specified seals
- Check of gaps and closing after fitting
- Removal of damaged or painted seals
What the rules say for Derry
Derry is in Northern Ireland, where fire doors are covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E on fire safety. Duties in non-domestic premises come from the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010.
The English regulation 10 checking regime does not apply here, so the fire risk assessment sets how often doors in Derry are checked. We hand over evidence that supports it.
Who needs intumescent strips and smoke seals in Derry?
Typical settings for intumescent strips and smoke seals include care homes, HMOs and schools. In Derry, as anywhere, the duty holder varies: a responsible person for a workplace, a landlord or managing agent for a block or HMO, or a homeowner after building work. We adjust access, timing and paperwork to suit whoever commissions the work.

Questions
Is Derry within your coverage area?
It is. We cover Derry in County Londonderry and neighbouring towns such as Coleraine. 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 smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
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.
