- Fire dampers that haven’t been tested for over a year
Fire damper testing in Force Green
Testing finds the dampers that won’t close. Where a blade sticks, a link is damaged or corrosion has set in, we note it and can quote to repair or replace the damper, so the fault doesn’t just sit on a list. We are often asked to deal with fire dampers that haven’t been tested for over a year and dampers hidden with no access panel or hatch, on fusible link fire dampers, riser dampers and offices and schools.
Across London, buildings with ducted ventilation have a fire damper wherever a duct crosses a fire-resisting wall or floor. A taller building in Force Green can have dampers spread across risers, plant rooms and ceiling voids.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Part by part
Ceiling voids and risers
Risers and service shafts often hold dampers at each floor. We work through them floor by floor so nothing is missed.
Fusible link fire dampers
The link has to be in good order for the damper to work. Each link is looked at as part of the test and note anything that isn’t right.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Common problems we fix in Force Green
The law puts a duty on the responsible person to keep fire safety systems, dampers included, in working order. Employers, owners, landlords and managing agents all need evidence that the dampers have been checked.
Common reasons sites call us include:
- Dampers clogged with dust or grease
- Rusted damper blades and springs
- Gaps in the fire damper test log
- Dampers that stick or won’t close fully
Healthcare buildings such as Tandridge Priory (about 2.7 miles south-west) rely on fire compartments, and the dampers in them need testing at least annually.
Questions to ask before you book
- Whether a written report and pictures are included
- Whether the figure could change on the day
- Whether the quote shows VAT
- Proof of accreditation you can verify
Why deal with it now?
If a damper can’t close, the wall it sits in has a hole in it during a fire. Everything else about the compartment can be right and the duct still lets it down. Testing now is how you find out before it matters. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

Keeping the system healthy
Once we have finished, these simple steps help:
- File every damper report where your assessor can find it
- Fix water leaks in plant rooms and risers promptly
- Book the next test before the year runs out
- Close off damper faults promptly
Any damper that failed is listed with the reason, and we can quote for remedials. Once the work is done, the damper is tested again and the record updated.
Where a damper sits in ductwork that collects dust or grease, keeping that ductwork clean helps. It makes sense to plan duct cleaning and damper testing together.

Not every problem is solved by fire damper testing, and we’ll tell you before any work starts. It will not put right:
- Approving the building’s fire strategy
- Fire risk assessments, which need a fire risk assessor
- Ductwork crossing a fire wall with no damper fitted

The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a couple of hours for a few dampers, and a day or more across a big site. Loading bays, visitor permits and roof access are the first things we ask about for a site in Force Green.
- First we look at any damper register, drawings or earlier test reports.
- Dampers are located one by one and reached through their access panels.
- Every fire damper is dropped, and every smoke damper is tested through its controls.
- Dampers that close fully are reset and left open.
- You get a report listing each damper, its result and any remedials needed.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
Getting a quote
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Questions from Force Green
Is parking a problem for work in Force Green?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Which fire authority looks after Force Green?
Force Green is in the area of London Fire Brigade. If a fire safety officer audits the building, they may ask for the latest damper test records.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Who has the duty to keep fire dampers working?
Under the Fire Safety Order 2005, it’s the responsible person, such as the employer, owner, landlord or managing agent. Keeping fire safety systems working, dampers included, is part of their duty.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
What paperwork do we get after testing?
Our paperwork is a test report, not a certificate of compliance. It lists each damper, the result and any remedials needed.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s 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.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
