How we handle fire damper testing in Thorpe
Fire dampers sit inside ductwork where it passes through a fire-resisting wall or floor. Most are held open by a fusible link that melts at a set temperature, letting the blade drop and close the duct. Drop testing proves that this still happens, and every result is written down, damper by damper. If you’re dealing with missing or out-of-date damper records and damper actions from a fire risk assessment, we can help, from hospitals and care homes, riser dampers and wall and floor dampers onwards.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. A first test typically starts with finding them all.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How the visit works
We turn up 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 before any work starts, and floors and nearby surfaces are sheeted. The work itself takes a morning or an afternoon for a small number of dampers, longer where there are many. If the van will struggle with a lane or gateway near Thorpe, let us know and we will plan around it.
- We plan access and timing with you first, including any out-of-hours work.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- We release each blade and check it shuts all the way.
- The damper is reset and its condition noted.
- Panels and tiles go back, and the results are written up.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand

Fire damper testing in Thorpe: local notes
Food Standards Agency records list about 11 schools, colleges and universities and about 7 care, childcare and hospital premises registered as food businesses within about 1.5 miles of central Thorpe. 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. Fire safety in Thorpe falls to Surrey Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. The nearest hospital to Thorpe is Runnymede Hospital, about 2.2 miles south. 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.
Botleys Mansion, about 2.5 miles south, is one of the historic houses near Thorpe, and older buildings converted to new uses often have ventilation added later. A school like Thorpe CofE Aided Primary School can have any dampers tested over half-term without disturbing lessons.
Thorpe is about 2 miles south-east of Egham, in Surrey. From the centre of Thorpe to the outskirts, we cover fire damper testing for every kind of premises, from small sites to large estates.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Common problems we fix in Thorpe
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.
These are the problems we see most often:
- Dampers that can’t be reached without an access panel
- Dampers overdue for their annual drop test
- Corroded dampers in damp risers and plant rooms
- Dirty dampers that may not close
The nearest hospital, Runnymede Hospital, is about 2.2 miles south; healthcare buildings like it are a reminder that dampers protect people who cannot move quickly.

Why deal with it now?
If a damper cannot close, the wall it sits in has a hole in it during a fire. Everything else about the compartment can be right and the duct still lets it down. Testing now is how you find out before it matters. Rural sites can’t always move to another kitchen or room when something fails.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Looking after it afterwards
Once we have finished, these simple steps help:
- Warn anyone working in ceiling voids about the dampers
- Close off damper faults promptly
- Update the register when ductwork changes
- Keep cables and fixings away from damper blades
Tell other contractors where the dampers are, and ask them not to run cables through or wedge them. Anything they disturb should be checked again.
Clean ductwork means less dust and grease reaching the dampers. Duct cleaning and damper testing can be planned side by side.

Your questions about fire damper testing in Thorpe
Can you come to Thorpe after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Thorpe needn’t be disturbed. Your opening times are the first thing we ask for.
Who is the fire and rescue service for Thorpe?
Fire safety enforcement in Thorpe is handled by Surrey Fire and Rescue Service. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you certify fire dampers?
What you receive is a written report of each test, damper by damper. Failures are set out with the remedials we’d suggest.
What if a damper has no access panel?
The report lists each inaccessible damper and where it is, so you know exactly what’s outstanding. An access panel tends to solve it, and we can quote to fit one.
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.
