Intumescent strips and smoke seals: our service in Welwyn Garden City
Our intumescent strips and smoke seals service covers Welwyn Garden City and the wider Hertfordshire area. Every job starts with a survey of the openings, so the quote reflects your actual doors rather than a guess.
Fire doors in Welwyn Garden City protect escape routes in industrial estates, low-rise blocks of flats and HMOs alike. We adapt the programme to the building and its occupants, never the standard of the installation.
Seal replacement in Welwyn Garden City can be combined with any other remedials on the same inspection report. We check that each door in your Welwyn Garden City building closes and latches against its new seals before signing it off.
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.
Each installation includes:
- Identification of the specified seals
- Intumescent pads to hinges and locks
- Removal of damaged or painted seals
- Check of gaps and closing after fitting
Rules and responsibilities in Welwyn Garden City
The rules that apply to fire doors in Welwyn Garden City 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 Welwyn Garden City 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.

No. Paint stops brush and blade seals working. If seals have been painted, they should be replaced.
