Certified fire doorsets: our service in Dartford
From the DA1 postcode district outwards, we take on certified fire doorsets across Dartford for homes, blocks and workplaces.
Buildings in and around Dartford range from family homes after loft conversions to schools and high-street shops. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
Doorsets suit refurbishment programmes in Dartford, where several openings can be measured, ordered and fitted in one planned sequence. Every doorset we fit in Dartford is handed over with its certificate reference and photographs of the frame fixing and gap sealing.
Why choose a doorset over a door leaf?
A fire door's rating belongs to the assembly that was tested, not to the leaf on its own. When a certified leaf is hung in an old frame with mismatched hinges and seals, nobody can say with confidence how it will perform. A doorset arrives with the frame, gaps and ironmongery already matched, so the installer's job is to fix it correctly into the opening and seal it to the structure.
Doorsets also cut time on site, which matters in occupied buildings: less cutting, less dust and fewer return visits.
What you get:
- Installation to the manufacturer's instructions
- Frame fixing and frame-to-wall gap sealing
- Closer set-up and close-and-latch testing
- Pre-hung, pre-machined doorsets where available
What the rules say for Dartford
Fire doors in Dartford fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.

Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Common questions
Do you work in Dartford?

What happens on a survey in Dartford?
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 doorsets take to arrive?
Lead times depend on the manufacturer, size, finish and ironmongery. Standard sizes can be quick; bespoke sizes and finishes take longer. We give you the lead time with the quote and confirm it at order.
Are doorsets more expensive than a leaf?
The product costs more, but the labour is often lower and the result is better evidenced. Where a frame would need replacing anyway, a doorset is usually the better value.
