Certified fire doorsets in Hertford, done to the evidence
We provide certified fire doorsets in Hertford (SG13 and the surrounding postcodes), from the first survey through to a documented handover.
Buildings in and around Hertford range from light industrial buildings to family homes after loft conversions and houses with integral garages. 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 Hertford, where several openings can be measured, ordered and fitted in one planned sequence. Every doorset we fit in Hertford 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.
As standard, the work covers:
- Installation to the manufacturer's instructions
- Doorset selection to rating, size and use
- Closer set-up and close-and-latch testing
- Pre-hung, pre-machined doorsets where available

Questions from Hertford
Is Hertford within your coverage area?
It is. We cover Hertford in Hertfordshire and neighbouring towns such as Hoddesdon. There is no charge for the survey.
Can you work from an existing inspection report for my Hertford building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
Can a doorset be fitted into an existing opening?
Usually, yes. Doorsets are made to fit the structural opening once the old frame is removed. We measure the opening on the survey so the doorset is made to the right size and the gaps to the wall stay within what the evidence allows.
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.
