Fire damper testing in Bexleyheath, done properly
In a fire, ductwork can act as a shortcut for flame and smoke from one part of a building to the next. A damper only does its job if the blade can drop fully. Annual drop testing is how you know in each part of the building. The work covers motorised smoke dampers, wall and floor dampers and fusible link fire dampers, and common reasons people get in touch are fire dampers that fail to drop shut and dampers hidden with no access panel or hatch.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. A taller building in Bexleyheath can have dampers spread across risers, plant rooms and ceiling voids.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
So the system stays in good health:
- File every damper report where your assessor can find it
- Brief other trades about dampers in ceilings and risers
- Diary the annual test well ahead
- Do not let hatches get painted shut or boarded over
Make sure trades working in ceilings and risers know where the dampers sit, and ask them not to run cables through or wedge them. If a damper has been disturbed, have it tested again.
Make sure every damper can be reached. If a damper has no access panel, have one fitted ahead of the next visit.
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.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When it’s something else
A few issues sit outside what this work can do:
- Gaps in the wall or floor around the damper
- Approving the building’s fire strategy
- Dampers that were never installed where they’re needed
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
Parts of the system we cover
- Offices and schools
- Hospitals and care homes
- Riser dampers
- Motorised smoke dampers
- Fusible link fire dampers
- Wall and floor dampers
What happens if it’s left?
If a damper cannot 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. Planning ahead in Bexleyheath lets you pick a quiet night rather than lose a busy one.

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 32 schools, colleges and universities with registered kitchens within about a mile and a half of Bexleyheath. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
What do you need to know about parking in Bexleyheath?
Tell us where a van can stop near your site in Bexleyheath, and about any building rules on loading. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
How long will damper testing take?
It takes anything from a couple of hours for a handful of dampers to a full day for a large building. Access is the biggest factor, and we’ll give you an idea when we quote.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Is TR19 a legal requirement?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
Who has the duty to keep fire dampers working?
The responsible person under the Regulatory Reform (Fire Safety) Order 2005, such as the employer, owner, landlord or managing agent. They must keep fire safety measures, including dampers, in working order.
Bexleyheath buildings and fire safety
The FSA’s food hygiene register lists about 32 schools, colleges and universities, about 61 hospitals, care homes and childcare premises and about 4 hotels and guest houses with registered kitchens or food service within 1.5 miles or so of the middle of Bexleyheath. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Ceiling voids and risers in London buildings can hold many dampers, and each one has to be reached and recorded. London Fire Brigade covers Bexleyheath. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and keeping dampers working is part of the responsible person’s duty.
Site managers at schools such as Upland Primary School normally find the summer break the easiest time for ceiling work like damper testing. For managed buildings around Bexleyheath station, damper testing can be booked out of hours so tenants aren’t disturbed. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Red House is about 0.4 miles south-west), finding every damper is the first job.

Damp plant areas are hard on dampers. We note any rust or water damage on the report so it can be dealt with.
Smoke dampers
Smoke dampers are motorised and run by a control system. Testing means operating them from the controls and check each blade travels fully.
How the visit works
