Intumescent strip and smoke seal fitting in Heston

Intumescent strips and smoke seals for Heston buildings

From the TW5 postcode district outwards, we take on intumescent strips and smoke seals across Heston for homes, blocks and workplaces.

Buildings in and around Heston range from purpose-built blocks of flats to care homes and restaurants. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.

We check that each door in your Heston building closes and latches against its new seals before signing it off. Painted and missing seals are among the most common fire door defects nationally; in Heston we replace them with the type and size the certification specifies.

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.

On a typical job that means:

• Check of gaps and closing after fitting
• Intumescent pads to hinges and locks
• Brush or blade smoke seals
• Intumescent strips in frame or leaf edge

The regulations behind fire doors in Heston

Fire doors in Heston 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. Enforcement of fire safety law in Heston sits with the London Fire Brigade.

For residential buildings in Heston 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.
