About our fire damper testing in Agar Town
Fire dampers sit inside ductwork where it passes through a fire-resisting wall or floor. 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 every result is written down, damper by damper. We are often asked to deal with dampers flagged on a fire risk assessment and dust or grease build-up on damper blades, across fusible link fire dampers, wall and floor dampers and riser dampers.
Plenty of London buildings have been refitted more than once, and dampers are often left behind new ceilings with no way to reach them. In Agar Town, as across London, finding every damper and recording its access is part of the job.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a morning or an afternoon for a small number of dampers, longer where there are many. Before any visit in Agar Town, we agree where the van can stop and how equipment reaches the system.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- The blade is released and watched to make sure it closes fully.
- We reset it and record any dirt, corrosion or damage.
- We close everything up and send the results in a report.
How to prepare
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Common questions in Agar Town
Do you do school damper testing in Agar Town in the summer holidays?
Yes, holiday work suits schools best. Around Agar Town, the Food Standards Agency lists about 69 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
Is parking a problem for work in Agar Town?
A loading bay, a visitor permit or off-street space near the site in Agar Town makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
How much time does a damper test visit need?
A visit takes a couple of hours for a few dampers, and a day or more across a big site. Bigger sites can be phased, so phone us on 0345 646 2711, or email photos for a quote.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Leave it or put it right?
When something goes wrong, people ask what checks were in place. Damper test records are part of that answer, and they only exist if the testing happened. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Agar Town buildings and fire safety
Going by the FSA’s register, there are about 69 schools, colleges and universities, about 68 care, childcare and hospital premises and about 114 hotels, B&Bs and guest houses serving food in Agar Town and the streets around it, up to about 1.5 miles out. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Fire safety in Agar Town falls to London Fire Brigade. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. Managed London buildings typically need damper testing booked through the agent, often out of hours.
For managed buildings around Camden Road station, damper testing can be booked out of hours so tenants are not disturbed. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Winfield House is about 1.5 miles west), finding every damper is the first job.

Common problems we fix in Agar Town
Building work often happens right next to dampers. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
Common reasons sites call us are:
- Rusted damper blades and springs
- Dirty dampers that may not close
- Missing or out-of-date damper records
- Dampers hidden with no access panel or hatch
School buildings such as Abacus Belsize Primary School are normally tested in the holidays, wherever they have dampers.

- What’s included in the scope, part by part
- What happens if part of the system can’t be accessed
- When the next visit should be, and why
Multi-site and managed buildings
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
How we price fire damper testing
Sites vary more than people expect. What affects the quote:
- Any permits to work or inductions
- What state the system is in
- How many systems or sites are involved
- The size of the system
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What we need to know
There’s no need for technical detail. Just send:
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- The times we could work without disrupting the site
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- File every damper report where your assessor can find it
- Keep the damper register up to date after any building work
- Make sure access panels stay clear and usable
- Brief other trades about dampers in ceilings and risers
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.
The simplest way to avoid failures is to test on time, every year. A blade that’s just starting to stick is easier to deal with than a seized one.
