What intumescent strips and smoke seals in Boston should include
From the PE21 postcode district outwards, we take on intumescent strips and smoke seals across Boston for homes, blocks and workplaces.
Around Boston, family homes after loft conversions, schools and care homes 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.
We check that each door in your Boston 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 Boston we replace them with the type and size the certification specifies.
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.
As standard, the work covers:
- Check of gaps and closing after fitting
- Intumescent pads to hinges and locks
- Intumescent strips in frame or leaf edge
- Removal of damaged or painted seals
What the rules say for Boston
The rules that apply to fire doors in Boston are England's. The responsible person under the Regulatory Reform (Fire Safety) Order 2005 must keep fire doors in non-domestic premises and the common parts of flats in working order; the Fire Safety Act 2021 confirmed that this includes flat entrance doors onto common parts.
Where a Boston block is above 11 metres, regulation 10 of the 2022 regulations means communal doors are checked every three months and flat entrance doors annually on a best-endeavours basis. Replacement doors must also satisfy the Building Regulations, with Approved Document B as the guidance most building control bodies work from.

Questions from Boston
Do you cover PE21 and nearby postcodes?
Yes. We cover Boston including PE21, and nearby towns such as Spalding and Skegness. The survey and written quote are free.
What happens on a survey in Boston?
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.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
