Intumescent strips and smoke seals in Hertford, done to the evidence
From the SG13 postcode district outwards, we take on intumescent strips and smoke seals across Hertford for homes, blocks and workplaces.
Around Hertford, small offices, light industrial buildings and houses with integral garages all depend on fire doors that close, latch and seal. We survey each opening and tell you plainly which doors need work and which don't.
Painted and missing seals are among the most common fire door defects nationally; in Hertford we replace them with the type and size the certification specifies. Seal replacement in Hertford 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:
- Removal of damaged or painted seals
- Identification of the specified seals
- Brush or blade smoke seals
- Intumescent pads to hinges and locks
Fire door law for Hertford properties
England's framework applies in Hertford. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in Hertford, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.

Common questions
Is Hertford within your coverage area?
It is. We cover Hertford in Hertfordshire and neighbouring towns such as Hoddesdon. There is no charge for the survey.
What happens on a survey in Hertford?
We look at every door in scope: the leaf, frame, gaps, seals, hinges, closer, glazing and how the frame is fixed. You then get a written quote that prices each door separately.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
