About our fire damper testing in Manuden
Under BESA guidance, every fire damper is tested on completion of installation and then at least once a year. For spring-operated types, annual testing is the minimum. We carry out fire damper testing for buildings in Manuden and give you the records to show it’s been done. The work covers motorised smoke dampers, fusible link fire dampers and offices and schools, and people most often call us about corroded dampers in damp risers and plant rooms and fire dampers with no recent test record.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. The first visit starts by locating each damper.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes from an hour or two in a small building to several visits on a large estate. Visits to a village like Manuden are booked in advance, at a time that suits whoever runs the site.
- We start with whatever records exist: registers, drawings or old reports.
- Dampers are located one by one and reached through their access panels.
- Every fire damper is dropped, and every smoke damper is tested through its controls.
- Each one that passes is reset, ready to work.
- The results go into a report, with failed dampers and remedials listed.
How to prepare
- Find the previous report, if there is one
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, ring 0345 646 2711 or email us.

Fire dampers in Manuden buildings
There are about 3 schools, colleges and universities on the FSA’s food hygiene register within roughly a mile and a half of the centre of Manuden. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Manuden is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers. About 3.8 miles south of Manuden is Herts and Essex Hospital, the nearest hospital. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have.
If you manage a school site such as Manuden Primary School, any fire dampers can be tested in the holidays.
Manuden is about 4 miles north of Bishop's Stortford, in Hertfordshire. We carry out fire damper testing for businesses, landlords and public buildings in Manuden and the rest of Hertfordshire. Across Hertfordshire, we cover 381 places, and Manuden is one of them. There’s also a page for Chelmsford, about 19 miles away.
Our technicians cover all of the CM23 postcode area for fire damper testing and the streets around it.

We also cover the places around Manuden: Mount Pleasant (1 mile west), Bentfield Green (1 mile south-east), Uppend (1 mile west), Farnham (2 miles south-west) and Stansted Mountfitchet (2 miles south-east).

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Keep ceiling hatches and duct panels easy to open
- Keep cables and fixings away from damper blades
- Store test records alongside the fire risk assessment
- Brief other trades about dampers in ceilings and risers
Any damper that failed is listed with the reason, along with an offer to repair or replace them. Once the work is done, the damper is tested again and the record updated.
A simple register of every damper helps a great deal: location, type, last test date and result. It means nothing gets forgotten when staff or contractors change.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
What we are called out for in Manuden
Rust is a frequent reason a damper will not close. Water leaks, condensation and damp plant areas attack the casing, blade and spring, and the damper can seize quietly where no one sees it.
What we’re most often called out for:
- Smoke dampers that need testing through their controls
- Missing or out-of-date damper records
- Corroded dampers in damp risers and plant rooms
- Fire dampers nobody can get to
The nearest hospital, Herts and Essex Hospital, is about 3.8 miles south; healthcare buildings like it are a reminder that dampers protect people who cannot move quickly.
Questions to ask before booking
- Proof of accreditation you can verify
- Whether the figure could change on the day
- What happens if part of the system can’t be accessed
- How they set the interval to the next visit
What affects the quote in Manuden
We quote each job individually. These are the things that affect it:
- Where the site is and how we reach it
- One-off work versus a regular cycle
- What state the system is in
- The size of the system
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Any access panels or hatches you can see
- A few general shots of the system
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Manuden questions
Do you work at weekends in Manuden?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just phone us on 0345 646 2711 or email us with your opening times and we will plan around them.
Will you come out to Manuden?
Yes. Manuden is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
How long will damper testing take?
As a guide, it takes a morning or an afternoon for a small number of dampers, longer where there are many. It comes down mainly to how many dampers there are and how easy they are to get to.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Do you certify fire dampers?
You get a test report recording every damper we tested, showing where it is, whether it passed and what we found. It belongs in your fire safety log.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Why act early in Manuden
A damper that is stuck open gives fire and smoke a route straight through a fire-resisting wall. The rest of the compartment can be built perfectly and still be bypassed by the duct. Testing now is how you find out before it matters. If the system at a site near Manuden fails, there may be nowhere nearby to move to.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right 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, and that’s where we come in.
