Fire damper testing in Deacon's Hill

Ductwork can carry fire and smoke between compartments, and the damper is what stops it. That depends entirely on the blade closing all the way. Annual drop testing is how you know for the dampers in your building. Common call-outs are for damper actions from a fire risk assessment and rusted damper blades and springs, across wall and floor dampers, offices and schools and hospitals and care homes.

Testing in a small place like Deacon's Hill is planned around the journey and access, and the test itself is the same as in any city building.

Nothing is signed off by word of mouth: a dated report with pictures of the work, 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.

Deacon's Hill buildings and fire safety

Going by the FSA’s register, there are about 18 schools, colleges and universities and about 14 hospitals, care homes and childcare premises serving food across Deacon's Hill and its immediate surroundings (about a mile and a half). Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. Hertfordshire Fire and Rescue Service covers Deacon's Hill. Under the Fire Safety Order, the responsible person has to keep fire safety systems, dampers included, in working order, and the fire authority enforces that in most non-domestic premises. For Deacon's Hill, the closest hospital is Royal National Orthopaedic Hospital, roughly 1.4 miles south-west. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed.

Headstone Manor, about 4.7 miles south-west, is one of the historic houses near Deacon's Hill, and older buildings converted to new uses often have ventilation added later. Wherever there are offices above shops, near Elstree & Borehamwood station or elsewhere in Deacon's Hill, ductwork may cross fire-resisting floors, and any dampers need testing.

How it works

We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a morning or an afternoon for a small number of dampers, longer where there are many. If you can send pictures, we can arrive in Deacon's Hill knowing what to expect.

  1. We gather what’s known about the dampers, from drawings, registers or past reports.
  2. Each damper is located and reached through its access panel.
  3. Fire dampers are drop tested and smoke dampers are run through their controls.
  4. Dampers that close fully are reset and left open.
  5. You get a report listing each damper, its result and any remedials needed.

Before we arrive

  • Plan for cooking equipment or plant to be off before we arrive
  • Tell us where we can park and unload
  • Clear the space around the work

Common questions in Deacon's Hill

Who is the fire and rescue service for Deacon's Hill?

Deacon's Hill is in the area of Hertfordshire Fire and Rescue Service. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.

Is Deacon's Hill within the area you cover?

Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.

What if parts of the system can’t be reached?

We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.

Who is the responsible person?

That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and you’ll get one fixed quote.

Do you test dampers in the evening or at weekends?

Yes, the visit is arranged to suit the site. Out-of-hours and weekend work is available if daytime testing would get in the way.

Where does the waste go?

It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.

Can we book visits on a schedule?

Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.

Signs you need fire damper testing in Deacon's Hill

Other trades work around dampers all the time. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.

It’s time to book a visit if you see:

  • Missing or out-of-date damper records
  • Blades that jam part-way when released
  • Dust or grease build-up on damper blades
  • Motorised smoke dampers due for testing

Royal National Orthopaedic Hospital, about 1.4 miles south-west of Deacon's Hill, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

Before you book anyone

  • What happens if part of the system can’t be accessed
  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether the quote shows VAT
  • Whether the price is fixed

Choosing a duct cleaning contractor

What a clean won’t put right

In fairness, some problems need a different fix:

  • Faults in the alarm or building controls that signal smoke dampers
  • Approving the building’s fire strategy
  • Ductwork crossing a fire wall with no damper fitted

If you are not sure, just call 0345 646 2711 or use the quote form and we’ll give you a straight answer.

What we work on in Deacon's Hill

  • Offices and schools
  • Hospitals and care homes
  • Wall and floor dampers
  • Fusible link fire dampers
  • Riser dampers
  • Motorised smoke dampers

Multi-site and managed buildings

Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

How we price fire damper testing

You will get a fixed price before we start. It takes into account:

  • Working hours and out-of-hours timing
  • Whether it’s a one-off visit or part of a schedule
  • Travel, parking and unloading
  • Site rules, permits and inductions

What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.

What we need to know

What to send for a quote:

  • How we’d reach plant on a roof or in a plant room
  • Your last certificate, test record or report
  • Photos showing the whole system and its surroundings
  • Detail shots of panels, filters and grilles

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then ring 0345 646 2711, or email photos.

Keeping the system healthy

To keep the system working properly between visits:

  • Do not let hatches get painted shut or boarded over
  • Add new dampers to the register as they’re fitted
  • Store test records alongside the fire risk assessment
  • Book the next test before the year runs out

Failed dampers are set out separately, each with the fault we found, and we can quote for remedials. After a repair, we retest the damper and update the record.

Make sure every damper can be reached. Where there’s no hatch, an access panel makes testing possible before the next test.
