Fire and smoke damper testing in Canonbury
For fire damper drop testing and smoke damper testing, with a record for each damper in Canonbury, one call is all it takes: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Buildings with no damper register
- Dampers hidden with no access panel or hatch
- Fire dampers that fail to drop shut
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes from an hour or two in a small building to several visits on a large estate, and the area is cleaned down before we leave. We fit London jobs around the building rather than the other way round, so a visit in Canonbury is usually out of hours.
- 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.
Getting ready for the visit
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.

Fire damper testing in Canonbury
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 we record the result for every damper we test. If you’re dealing with corroded dampers in damp risers and plant rooms and dampers that can’t be reached without an access panel, we can put it right, from offices and schools, riser dampers and hospitals and care homes onwards.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. In a larger building in Canonbury, that can mean dampers on every floor, many of them above ceilings or in risers.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Canonbury
In most buildings, Canonbury included, dampers are out of sight in ceiling voids, risers and service shafts. If there’s no hatch to reach them, they slip off everyone’s list, and anything nobody can get to goes untested.
Keep an eye out for these warning signs:
- Dampers clogged with dust or grease
- Fire dampers that haven’t been tested for over a year
- Rusted damper blades and springs
- Dampers that stick or won’t close fully
For managed buildings around Canonbury station, damper testing can be booked out of hours so tenants aren’t disturbed.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What happens if it’s left?
Putting testing off does not change whether the dampers will close; it just means you don’t know. BESA guidance is to test at least annually, so a missed year leaves a gap in the record too. Choosing the date yourself beats having a fault choose it for you.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

Fire dampers in Canonbury buildings
Food Standards Agency records list about 44 schools, colleges and universities, about 64 hospitals, care homes and childcare premises and about 18 hotels and guest houses registered as food businesses within about 1.5 miles of central Canonbury. 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. Canonbury sits within the area of London Fire Brigade. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers. In a London building, dampers are often spread across floors and risers, and testing is usually planned out of hours.
For schools like Rotherfield Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. Historic buildings that have had ventilation added later can hide dampers in awkward places; Sutton House, about 1.7 miles east, is one of the historic houses in the area around Canonbury.

FAQs for Canonbury
Do you test dampers in schools in Canonbury during the holidays?
Yes, and it’s the easiest time to do it. Around Canonbury, the Food Standards Agency lists about 44 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you work in Canonbury outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Canonbury needn’t be disturbed. Just call 0345 646 2711, or email photos with your opening times and we will plan around them.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
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.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Do we lose a day’s trading?
Typically not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Part by part
Access panels
Over time, hatches and panels get covered up. Letting us know where they are speeds the visit up.
Ceiling voids and risers
Ceiling voids are where lots of dampers end up. We lift tiles where needed and put them back as we found them.
What fire damper testing can’t fix
Fire damper testing cannot fix everything, and we’ll tell you before work begins. It won’t put right:
- Designing the building’s fire compartments
- Holes around ductwork in fire-resisting walls
- Sign-off of the whole building’s fire safety
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before booking.
