Intumescent strips and smoke seals in Hitchin

Intumescent strips and smoke seals for Hitchin buildings

We provide intumescent strips and smoke seals in Hitchin (SG6 and the surrounding postcodes), from the first survey through to a documented handover.

Around Hitchin, houses with integral garages, light industrial buildings and schools 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 Hitchin we replace them with the type and size the certification specifies. We check that each door in your Hitchin building closes and latches against its new seals before signing it off.

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.

Each installation includes:

• Removal of damaged or painted seals
• Brush or blade smoke seals
• Intumescent pads to hinges and locks
• Check of gaps and closing after fitting

What the rules say for Hitchin

England's framework applies in Hitchin. 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 Hitchin, 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.
