FAQs for Codicote
Which fire service covers Codicote?
That’s Hertfordshire Fire and Rescue Service. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Can a school’s dampers in Codicote be tested out of term time?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Codicote, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or drop us a line with the dates the site is empty.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Is a quote from photos possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
How we handle fire damper testing in Codicote
Fire dampers sit inside ductwork where it passes through a fire-resisting wall or floor. Most are held open by a fusible link that melts at a set temperature, letting the blade drop and close the duct. A drop test shows that the damper still does that when it matters, and every result is written down, damper by damper. Common call-outs are for dampers clogged with dust or grease and fire damper items raised by an assessor, on motorised smoke dampers, riser dampers and hospitals and care homes.
Around a place like Codicote, dampers tend to be in schools, care homes, surgeries and hotels rather than big offices. The duty to keep them working is the same as in a city.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Signs you need fire damper testing in Codicote
In most buildings, Codicote included, dampers are out of sight in ceiling voids, risers and service shafts. If there’s no hatch to reach them, they slip off everyone’s list, and one that cannot be reached can’t be tested.
What we’re most often called out for:
- Smoke dampers that need testing through their controls
- Fire dampers that haven’t been tested for over a year
- Dust or grease build-up on damper blades
- Blades that jam part-way when released
The nearest hospital, Queen Elizabeth II Hospital, is about 5 miles south-east; healthcare buildings like it are a reminder that dampers protect people who cannot move quickly.

What a clean will not put right
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Fire alarm or control system faults behind a smoke damper
- Signing off a building’s overall fire safety
- Designing the building’s fire compartments
If in doubt, give us a ring on 0345 646 2711, or email photos and we will say what we think before booking.
What the work covers
- Fusible link fire dampers
- Riser dampers
- Wall and floor dampers
- Hospitals and care homes
- Offices and schools
- Motorised smoke dampers
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Don’t let anything obstruct a damper’s blade
- Close off damper faults promptly
- Warn anyone working in ceiling voids about the dampers
- Make sure access panels stay clear and usable
Any damper that failed is listed with the reason, and we can quote for remedials. After a repair, we retest the damper and update the record.
The simplest way to avoid failures is to test on time, every year. Faults caught early are easier to fix.
Part by part
Schools, hospitals and care homes
Where residents can’t easily get out, holding fire and smoke back matters even more. Annual damper testing is part of keeping that in place.
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. Heat melts the link and the blade falls shut across the duct. We release the blade, check it closes fully and reset it.
Fire damper testing around Codicote
Going by the FSA’s register, there are about 5 hospitals, care homes and childcare premises serving food in Codicote and the streets around it, up to about 1.5 miles out. Buildings like these often have ducted ventilation, and wherever a duct crosses a fire-resisting wall or floor there should be a damper, tested at least once a year. About 5 miles south-east of Codicote is Queen Elizabeth II Hospital, the nearest hospital. Hospitals are a good example of a building with fire dampers across many floors and departments. Fire safety in Codicote falls to Hertfordshire Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order.
A school like Codicote Church of England Primary School can have any dampers tested over half-term without disturbing lessons. Historic houses near Codicote, with Shaw's Corner about 1.7 miles south-west, are a reminder that older buildings can hold dampers in unexpected places.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Everything the job in Codicote needs is worked out beforehand, from the survey.
- We plan access and timing with you first, including any out-of-hours work.
- We open up ceilings and hatches and take off each access panel.
- We release each blade and check it shuts all the way.
- We reset it and record any dirt, corrosion or damage.
- Panels and tiles go back, and the results are written up.
Before we arrive
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
