Intumescent strips and smoke seals in Watford: what's involved
When you book intumescent strips and smoke seals in Watford, the aim is simple: doors that close, latch and seal as tested, with records that prove it.
In and around Watford, fire door work covers everything from converted period houses to industrial units. We plan each job around the people who use the building.
Seal replacement in Watford can be combined with any other remedials on the same inspection report. We check that each door in your Watford building closes and latches against its new seals before signing it off.
Getting the specification right
The door's certification states the type, size and position of strips and seals: in the frame or the leaf edge, single or double, and whether a combined intumescent and smoke seal is used. Replacements must match. Swapping in a generic strip from a hardware shop can undermine the door's performance.
What you get:
- Intumescent pads to hinges and locks
- Brush or blade smoke seals
- Check of gaps and closing after fitting
- Intumescent strips in frame or leaf edge

What happens on a survey in Watford?
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.
How long do seals last?
It depends on use and care. Seals on busy doors wear faster. Regular inspections will show when they need replacing.
Do all fire doors need smoke seals?
Only where the door is specified for smoke control, such as FD30S doors. Many doors on escape routes and flat entrances are specified this way.
