How we handle fire damper testing in Mark Hall South
Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. A drop test shows that the damper still does that when it matters, and we record the result for every damper we test. The work covers motorised smoke dampers, riser dampers and offices and schools, and the jobs we see most are dampers that stick or won’t close fully and corroded dampers in damp risers and plant rooms.
Buildings around Mark Hall South may have just a handful of dampers, and each still needs an annual drop test at least, with a record of every result.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Looking after it afterwards
Once we have finished, these simple steps help:
- Don’t let hatches get painted shut or boarded over
- Tell contractors where dampers are before they start work
- Fix water leaks in plant rooms and risers promptly
- Act on failed dampers rather than leaving them on file
Pass the report to whoever keeps your fire risk assessment up to date so their assessment matches what was found. Faults on the report are worth closing off quickly.
Make sure every damper can be reached. Where there’s no hatch, an access panel makes testing possible ahead of the next visit.
When something else is needed
Some problems need a different service or another trade:
- Ductwork crossing a fire wall with no damper fitted
- Fire risk assessments, which need a fire risk assessor
- Signing off a building’s overall fire safety
If you’re not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What affects the quote in Mark Hall South
Before we fix a price, we need to know a few things. We look at:
- Any permits to work or inductions
- The condition of the system
- The times the site is available
- The scale of the work
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
To speed up the quote, send us:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then phone us on 0345 646 2711, or email photos.
What fire damper testing looks like in Mark Hall South
The FSA’s food hygiene register lists about 27 schools, colleges and universities, about 38 caring premises (care homes, nurseries and hospitals) and about 8 hotels and B&Bs with registered kitchens or food service in Mark Hall South 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. Mark Hall South sits within the area of Essex County Fire and Rescue Service. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. About 1.4 miles west of Mark Hall South is Princess Alexandra Hospital, the nearest hospital. Hospitals are a good example of a building with fire dampers across many floors and departments.
Site managers at schools such as Cooks Spinney Primary Academy and Nursery normally find the summer break the easiest time for ceiling work like damper testing. Princess Alexandra Hospital, about 1.4 miles west of Mark Hall South, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes a few hours for a single floor, with bigger buildings phased over more than one visit. Around Mark Hall South, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- Before the visit, we agree access, timings and any areas with restrictions.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- We release each blade and check it shuts all the way.
- We reset it and record any dirt, corrosion or damage.
- We close everything up and send the results in a report.
How to prepare
- Move anything stored near the system
- Tell us where we can park and unload
- Agree a time when the area can be out of use

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Mark Hall South: your questions answered
Do you work overnight in Mark Hall South?
Yes, we can come after you close and finish before you open. The work in Mark Hall South can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Do you do school damper testing in Mark Hall South in the summer holidays?
Yes, holiday work suits schools best. With about 27 schools and colleges on the FSA’s register within roughly a mile and a half of Mark Hall South, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we will fit the work in.
How long will damper testing take?
Expect it to take a morning or an afternoon for a small number of dampers, longer where there are many. How easily we can reach the dampers makes the most difference, so we’ll confirm the time when we quote.
Do we lose a day’s trading?
Not normally. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.
Will we get a certificate for the dampers?
Our paperwork is a test report, not a certificate of compliance. For each damper it shows the result and anything that needs putting right.
Whose job is it to make sure fire dampers are tested?
The Regulatory Reform (Fire Safety) Order 2005 puts it on the responsible person. Testing at least yearly and keeping the reports is how they can show it’s being done.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.

What else we do in Mark Hall South
Leave it or put it right?
Faults found early are often simpler to put right. Left for years, corrosion and build-up can turn it into a full damper replacement. It’s easy to lose track of when the work was last done on a quieter site.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before we start.
