About our fire damper testing in West Silvertown
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 we record the result for every damper we test. If you’re dealing with fire dampers nobody can get to and fire dampers with no recent test record, we can put it right.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. In a larger building in West Silvertown, that can mean dampers on every floor, many of them above ceilings or in risers.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Why it’s worth doing now in West Silvertown
When something goes wrong, people ask what checks were in place. A damper test log helps show the responsible person kept on top of things, and they only exist if the testing happened. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
What you get with us

What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Common problems we fix in West Silvertown
The law puts a duty on the responsible person to keep fire safety systems, dampers included, in working order. Whoever that is, whether employer, owner, landlord, facilities manager or managing agent, needs to be able to show the dampers work.
Keep an eye out for any of the following:
- Corroded dampers in damp risers and plant rooms
- Dampers flagged on a fire risk assessment
- Fire dampers with no recent test record
- Blades that jam part-way when released
For schools like Britannia Village Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear.

West Silvertown buildings and fire safety
Going by the FSA’s register, there are about 49 schools, colleges and universities, about 42 hospitals, care homes and childcare premises and about 17 hotels and guest houses serving food in and around West Silvertown, up to about a mile and a half out. 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. About 0.8 miles north-east of West Silvertown is Albert Dock Seamen's Hospital, the nearest hospital. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed. The fire and rescue service for West Silvertown is London Fire Brigade. 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.
Historic buildings that have had ventilation added later can hide dampers in awkward places; Queen's House, about 2 miles south-west, is one of the historic houses in the area around West Silvertown. For buildings around Custom House station with ducted ventilation, any fire dampers need an annual test at least.

Part by part
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. When the link reaches its set temperature it melts, and the blade drops to close the duct. Testing means dropping the blade, checking the full close and resetting it.
Access panels
Testing depends on getting to the damper. Most need an access panel in the duct and a hatch in the ceiling or wall.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
What happens on the day
A visit follows the same order every time: protect the area, make the system safe, carry out the fire damper testing, clear away and hand over the paperwork. The visit itself takes a few hours for a single floor, with bigger buildings phased over more than one visit. If your building in West Silvertown has sign-in rules, permits or key holders, mention them when you book.

Related advice
Looking after it afterwards
To keep the system working properly between visits:
- Fix water leaks in plant rooms and risers promptly
- Don’t let anything obstruct a damper’s blade
- Update the register when ductwork changes
- Brief other trades about dampers in ceilings and risers
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.
Water is a damper’s enemy, so fix leaks and condensation near them promptly. Corrosion is a common reason blades stick.
West Silvertown questions
Can a school’s dampers in West Silvertown be tested out of term time?
Yes, and it’s the easiest time to do it. There are about 49 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of West Silvertown. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Can you come to West Silvertown after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can you fix fire dampers that fail?
We record the damper as failed, with the reason, such as a sticking blade, corrosion or a damaged link. We offer remedials to repair or replace it, and it’s tested again once the work is done.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. If pictures are not enough, we’ll survey first.
What paperwork do we get after testing?
The record we give you is a report of the tests for every damper on the visit. Any failures come with a note of the remedials needed.
Is TR19 a legal requirement?
No. TR19® itself is not law; it’s a BESA specification. 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.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
