Part by part
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. Heat melts the link and the blade falls shut across the duct. Testing means dropping the blade, checking the full close and resetting it.
Offices and retail
Fit-outs and tenant changes are hard on dampers. A test after the works shows the dampers still close.
Fire damper testing in Clapham
Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. Drop testing proves that this still happens, and we record the result for every damper we test. Common call-outs are for blades that jam part-way when released and dust or grease build-up on damper blades, across motorised smoke dampers, fusible link fire dampers and offices and schools.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. In a larger building in Clapham, that can mean dampers on every floor, many of them above ceilings or in risers.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Managing agents and facilities teams in Clapham
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.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a couple of hours for a few dampers, and a day or more across a big site. If your building in Clapham has sign-in rules, permits or key holders, mention them when you book.
- Before the visit, we agree access, timings and any areas with restrictions.
- 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.
Before we arrive
- Have your last certificate or report to hand
- Clear the space around the work
- Agree a time when the area can be out of use

Advice
Fire dampers in Clapham buildings
Going by the FSA’s register, there are about 54 schools, colleges and universities, about 62 caring premises (care homes, nurseries and hospitals) and about 10 hotels, B&Bs and guest houses serving food within roughly a mile and a half of the centre of Clapham. 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. London buildings tend to have dampers on several floors, so testing is usually done out of hours, a zone at a time. Clapham is covered by London Fire Brigade. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you manage an older building converted to a hotel or venue, like many historic houses in the area (Carlyle's House is about 1.9 miles north-west), finding every damper is the first job. For managed buildings around Clapham High Street station, damper testing can be booked out of hours so tenants are not disturbed.
Clapham is about 3 miles north of Streatham, in Greater London. From the centre of Clapham to the outskirts, fire damper testing is available to all kinds of commercial premises, from small sites to large estates. Our Greater London coverage runs to 764 places, and Clapham is one of them.

When to call us in Clapham
Fusible links and springs do not last for ever. Damaged or painted links and weak springs mean the blade may stop short, and that only becomes clear during a drop test.
Keep an eye out for any of the following:
- Dust or grease build-up on damper blades
- Fire dampers with no recent test record
- Fire dampers that fail to drop shut
- Corroded dampers in damp risers and plant rooms
Battersea General Hospital, about 1.3 miles north-west of Clapham, is the kind of building where dampers protect every compartment; smaller care sites need the same annual tests.
Before booking anyone
- How areas they cannot reach will be recorded
- Whether the work can be done while the site is closed
- Which accreditations they hold, and whether you can check them
- If the quote is a fixed price or an estimate
When something else is needed
In fairness, some problems need a different fix:
- Control wiring problems outside the damper itself
- Ductwork crossing a fire wall with no damper fitted
- Fire risk assessments, which need a fire risk assessor
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think.

Which fire authority looks after Clapham?
London Fire Brigade is the fire and rescue service for Clapham. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.

Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

How we price fire damper testing
Every site gets its own quote. This is what makes a difference:
- What state the system is in
- How many systems or sites are involved
- Site rules, permits and inductions
- The times the site is available
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Asking for a quote
What to send for a quote:
- When the site is open and when it’s quiet
- Problems your staff have spotted
- The postcode and the type of business
- Wide pictures of the system and the area around it
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
