Fire damper testing for kitchens and businesses in Devil's Den

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. Common call-outs are for corroded dampers in damp risers and plant rooms and missing or out-of-date damper records, on riser dampers, motorised smoke dampers and wall and floor dampers.

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.

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.

Common problems we fix in Devil's Den

Other trades work around dampers all the time. Cables get run through them, links get knocked and blades get wedged open, and any of those can stop a damper closing.

Signs it’s time to call us include:

  • Blades that jam part-way when released
  • Fire dampers with no recent test record
  • Smoke dampers with no recent test
  • Dampers clogged with dust or grease

Every damper we test around Devil's Den gets its own entry in the report, with pictures.

Questions from Devil's Den

Who enforces fire safety at workplaces in Devil's Den?

That is Kent Fire and Rescue Service. Failed dampers on a report should be followed by a record of the repair, so the file shows the problem was closed out.

Do you cover smaller places like Devil's Den?

Yes. Devil's Den is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.

Do you have a 24/7 line?

Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.

What do you do with what you remove?

It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.

Do you have insurance?

Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.

How often do fire dampers need drop testing?

At least once a year, under BESA guidance, plus a test when the damper is first installed. Your fire risk assessment may call for some dampers to be tested more often.

Do you certify fire 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.

Do you offer maintenance contracts?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

Landlords, agents and facilities managers

Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

Fire damper testing around Devil's Den

At about 36 miles from central London, Devil's Den sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. Devil's Den is covered by Kent 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.

Historic buildings that have had ventilation added later can hide dampers in awkward places; Stoneacre, about 4 miles north, is one of the historic houses in the area around Devil's Den.

Devil's Den is about 5 miles south of Maidstone, in Kent. From the centre of Devil's Den to the outskirts, we cover fire damper testing for every kind of premises, from a single unit to a large public building. Devil's Den is one of 922 places in Kent we cover for commercial clients.

Looking after it afterwards

Here’s the after-treatment advice, short and simple:

  • Make sure access panels stay clear and usable
  • Keep an eye out for damp around dampers
  • Never wedge or tie a damper open
  • File every damper report where your assessor can find it

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.

Deal with leaks and condensation near dampers quickly. Corrosion is a common reason blades stick.

How it works

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a morning or an afternoon for a small number of dampers, longer where there are many. Somewhere like Devil's Den, lanes, gates and parking are worth mentioning in advance.

  1. First we look at any damper register, drawings or earlier test reports.
  2. We find every damper and open it up through the access panel.
  3. Every fire damper is dropped, and every smoke damper is tested through its controls.
  4. We reset every damper that passes and check it’s left open.
  5. You get a report listing each damper, its result and any remedials needed.

Getting ready for the visit

  • Let us know about permits to work or site inductions
  • Mention any parking or loading restrictions
  • Have your last certificate or report to hand

How to get a quote

To get a fixed quote, ring 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.

Related advice

In-house cleaning or a specialist?

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

What happens if it’s left?

An untested damper is an unknown. A test gives you a clear answer, and we can offer remedials for any that fail, and that’s something you can plan around. Planning a trip to Devil's Den ahead is easier for everyone than a rushed one.

Every site is different, 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 the work involves, part by part

Ceiling voids and risers

Where ductwork runs up through a building, there are often dampers at every floor. Testing goes floor by floor so nothing is missed.

Access panels

Over time, hatches and panels get covered up. Letting us know where they are speeds the visit up.
