Intumescent & Smoke Seal Replacement in Derbyshire

Managing buildings across Derbyshire? We cover fire door seal replacements in Derby, Chesterfield, High Peak and the rest of the county with one point of contact.

Intumescent & Smoke Seal Replacement: Intumescent seals are strips set into the edge of a fire door or its frame that expand when heated to close the gap around the door. Smoke seals, usually brush or fin seals, block cold smoke before the intumescent reacts. Both are part of the door's tested performance.

  • Fire Safety Order 2005: fire doors must be maintained (article 17)
  • Fire Safety Act 2021: flat entrance doors are within scope

Intumescent & Smoke Seal Replacement by town in Derbyshire

Intumescent & Smoke Seal Replacement in Derbyshire: questions

Can intumescent strips be painted?

Brush and fin smoke seals should never be painted, because paint stops them working. Some intumescent strips tolerate a light coat, but the safest rule is to mask all seals before decorating and replace any that have been painted.

What is the difference between an intumescent strip and a smoke seal?

An intumescent strip expands in heat to seal the gap during a fire. A smoke seal, often a brush or blade, blocks cold smoke at lower temperatures. Smoke control doors, marked with an S such as FD30S, need both.

Does regulation 10 apply to buildings in Derbyshire?

Yes, if the building is a multi-occupied residential building with storeys over 11 metres. Derbyshire is in England, so the quarterly communal door checks and annual flat entrance door checks apply to those buildings.

How quickly can you inspect fire doors in Derbyshire?

It depends on the number of doors and access. Tell us what you need and we will give you the earliest date when you call, and confirm it in writing.
