What intumescent strips and smoke seals in Harwich should include
For property owners, landlords and managing agents in Harwich, we offer intumescent strips and smoke seals with one team for the survey, the product and the installation.
Harwich has a broad mix of buildings, including care homes, family homes after loft conversions and small blocks of flats, and the same fire door principles apply to all of them.
We check that each door in your Harwich 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 Harwich 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.
On a typical job that means:
- Identification of the specified seals
- Brush or blade smoke seals
- Removal of damaged or painted seals
- Intumescent strips in frame or leaf edge
Rules and responsibilities in Harwich
The rules that apply to fire doors in Harwich 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 Harwich 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.

In Harwich, as anywhere, the duty holder varies: a responsible person for a workplace, a landlord or managing agent for a block or HMO, or a homeowner after building work. We adjust access, timing and paperwork to suit whoever commissions the work.

Questions
Do you work in Harwich?
Yes, we take on intumescent strips and smoke seals in Harwich and the surrounding area, including Felixstowe and Ipswich. Send your postcode and a few details and we'll come back with survey dates.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
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.
Can smoke seals be painted?
No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
