Fire and smoke damper testing in Hunton Bridge

How we handle fire damper testing in Hunton Bridge
Responsible persons, facilities managers and managing agents call us when damper testing falls due in Hunton Bridge. If there’s a damper register or a set of drawings, share it with us, and we will plan the visit around the building’s hours. If you have fire dampers that haven’t been tested for over a year and gaps in the fire damper test log, we can put it right.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. A first test normally starts with finding them all.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What a clean won’t put right
Some problems need a different service or another trade:
- Signing off a building’s overall fire safety
- Fire-stopping gaps around the duct where it passes through the wall
- Control wiring problems outside the damper itself
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.
Where we work
- Motorised smoke dampers
- Riser dampers
- Offices and schools
- Wall and floor dampers
- Hospitals and care homes
- Fusible link fire dampers
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Why deal with it now?
If a damper can’t close, the wall it sits in has a hole in it during a fire. The rest of the compartment can be built perfectly and still be bypassed by the duct. It’s far better to find that out on a test than in a fire. A planned visit to Hunton Bridge is easier to arrange than an emergency callout.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.

Your questions about fire damper testing in Hunton Bridge
Do you do school damper testing in Hunton Bridge in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 12 schools, colleges and universities with registered kitchens within about a mile and a half of Hunton Bridge. Just call 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Do you cover smaller places like Hunton Bridge?
Yes. Hunton Bridge is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Who has the duty to keep fire dampers working?
It’s the responsible person, under the Fire Safety Order 2005. Annual testing by a competent person, with written records, is a practical way to show the duty is being met.
Is TR19 a legal requirement?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711, or email photos.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

Are you insured?
Yes. We carry full insurance and have been trading since 2009.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
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.
What fire damper testing looks like in Hunton Bridge

Hunton Bridge sits within the area of Hertfordshire Fire and Rescue Service. 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.
Wherever there are offices above shops, near Kings Langley station or elsewhere in Hunton Bridge, ductwork may cross fire-resisting floors, and any dampers need testing. Healthcare buildings such as Leavesden Hospital (about 1.5 miles north-east) rely on fire compartments, and the dampers in them need testing at least annually.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Get remedials done soon after a failed test
- File every damper report where your assessor can find it
- Brief other trades about dampers in ceilings and risers
- Keep an eye out for damp around dampers
The next test should be no more than a year away. The guidance is at least once a year, so it helps to book it before the date slips.
Keep a damper register: where each damper is, what kind it is and when it was last tested. It means nothing gets forgotten when staff or contractors change.
