Leave it or put it right?
A sticking blade caught on an annual test can be a small repair. Years of corrosion and dirt can mean the whole damper needs replacing instead. Planning a trip to Blackthorn ahead is easier for everyone than a rushed one.
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

How we handle fire damper testing in Blackthorn
The idea behind drop testing is straightforward: we release the blade, watch it close fully, then reset it. We do this for buildings in Blackthorn and across Oxfordshire, logging each one so the record builds year on year. The work covers riser dampers, fusible link fire dampers and wall and floor dampers, and people most often call us about fire damper items raised by an assessor and blades that jam part-way when released.
In rural areas, conversions, country hotels and care homes can have ductwork crossing fire-resisting walls, and the dampers in them are easily forgotten. A first test usually starts with finding them all.
The paperwork matters as much as the work. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Blackthorn questions
Can you get to a site in Blackthorn?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you do school damper testing in Blackthorn in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Blackthorn, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or drop us a line with the dates the site is empty.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
Is a quote from photos possible?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
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 expects a risk-based approach.
How long does fire damper testing take?
Testing takes a morning or an afternoon for a small number of dampers, longer where there are many. Bigger sites can be phased, so ring 0345 646 2711 or send us an email for a quote.
How often does BESA say fire dampers should be tested?
BESA guidance calls for testing by a competent person at least once a year. A test on completion of installation comes first.
How much does fire damper testing cost in Blackthorn?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
How the job changes from site to site
Access panels
A damper can only be tested if it can be reached. That typically means an access panel in the duct, plus a way through the ceiling or wall.
Schools, hospitals and care homes
Buildings where people sleep or need help to leave rely heavily on compartments holding fire back. Annual damper testing is part of keeping that in place.

What else we do in Blackthorn
Between visits
Once we’ve finished, these simple steps help:
- File every damper report where your assessor can find it
- Report leaks or condensation near ductwork quickly
- Don’t let hatches get painted shut or boarded over
- Diary the annual test well ahead
Make sure trades working in ceilings and risers know where the dampers sit, and that they mustn’t tie, wedge or obstruct them. If a damper has been disturbed, have it tested again.
Keeping to at least annual testing stops small faults turning into failed dampers. A blade that’s just starting to stick is easier to deal with than a seized one.
What we are called out for in Blackthorn
In most buildings, Blackthorn included, dampers are out of sight in ceiling voids, risers and service shafts. Without an access panel nearby, they’re easy to forget, and one that cannot be reached can’t be tested.
Clients typically contact us when they notice one of these:
- Dampers flagged on a fire risk assessment
- Gaps in the fire damper test log
- Smoke dampers that need testing through their controls
- Fire dampers nobody can get to
A school like Five Acres Primary School can have any dampers tested over half-term without disturbing lessons.

Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning and specialist work aren’t the same thing. 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. That part needs specialist access and equipment.
How it works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. The timing of a visit to Blackthorn is set by you, and the travel is our side of the planning.
- 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.
- The blade is released and watched to make sure it closes fully.
- The damper is reset and its condition noted.
- Panels and tiles go back, and the results are written up.
How to prepare
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
