Fire and smoke damper testing in North Sheen

- Dampers flagged on a fire risk assessment
- Blades that jam part-way when released
- Dampers hidden with no access panel or hatch
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Update the register when ductwork changes
- Don’t let anything obstruct a damper’s blade
- Diary the annual test well ahead
- Keep damper test reports with the fire safety log
The next test should be no more than a year away. BESA guidance is at least annual testing, and booking the same month each year keeps it simple.
Keeping to at least annual testing stops small faults turning into failed dampers. Faults caught early are easier to fix.
Fire damper testing in North Sheen
BESA guidance is that fire dampers should be tested by a competent person when they’re installed and at least annually after that. Spring-operated dampers need testing every year as a minimum. Our job is to do the testing and hand you the paperwork that shows it. The work covers hospitals and care homes, riser dampers and offices and schools, and people most often call us about dampers that stick or won’t close fully and motorised smoke dampers due for testing.
Plenty of London buildings have been refitted more than once, and dampers are often left behind new ceilings with no way to reach them. Locating each damper in a building in North Sheen is the first part of a proper test.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Questions from North Sheen
Does London parking affect a job in North Sheen?
A loading bay, a visitor permit or off-street space near the site in North Sheen makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Who is the fire and rescue service for North Sheen?
It’s London Fire Brigade, which covers North Sheen. If a fire safety officer audits the building, they may ask for the latest damper test records.
How long does fire damper testing take?
Typically the work takes a few hours for a single floor, with bigger buildings phased over more than one visit. The number of dampers and how they’re reached decide the rest.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Can you fix fire dampers that fail?
We record the damper as failed, with the reason, whether that’s a stuck blade, rust or a damaged link. We offer remedials to repair or replace it, and test it again afterwards.
Can you price the work without visiting?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Do we lose a day’s trading?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
What affects the cost of fire damper testing
You’ll get a fixed price before we start. It takes into account:
- The condition we find in the survey
- The scale of the work
- Parking and loading at the site
- The times the site is available
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
What to send for a quote
Before you ask for a quote, gather:
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
Want a quote for fire damper testing? Please give us a ring on 0345 646 2711 or send us an email with a few details about the site. We will talk you through the work and send you a fixed quote before you commit to anything.
Different parts, different methods
Smoke dampers
Testing smoke dampers sometimes needs input from whoever looks after the control system. We plan that with you before the visit.
Fusible link fire dampers
For dampers closed by a spring, BESA guidance is annual testing as a minimum. A weak spring or a sticking blade shows up when the damper is dropped.
Fire dampers in North Sheen buildings
The FSA’s food hygiene register lists about 29 schools, colleges and universities, about 43 care, childcare and hospital premises and about 13 hotels, B&Bs and guest houses with registered kitchens or food service in North Sheen and the streets around it, up to about 1.5 miles out. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. For North Sheen, the closest hospital is Barnes Hospital, roughly 1.1 miles south-east. Hospitals are a good example of a building with fire dampers across many floors and departments. Testing in London is typically done zone by zone, evenings and weekends included, so occupants are not disturbed.
For schools like Kew Riverside Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. If you manage offices, shops or flats near Kew Gardens station, the ductwork in them may pass through fire-resisting walls and floors, and any dampers need testing at least once a year. Barnes Hospital, about 1.1 miles south-east of North Sheen, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a couple of hours for a few dampers, and a day or more across a big site, and the area is cleaned down before we leave. Before any visit in North Sheen, we agree where the van can stop and how equipment reaches the system.
- First we check the schedule and the last set of results.
- We locate every damper and note any we can’t reach.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Dampers that pass are reset, and failures are logged with what we found.
- We report the results and offer remedials on failed dampers.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
