How we handle fire damper testing in Cosham
Plenty of buildings have dampers nobody has looked at since they were fitted. Ceilings get lowered, hatches get boarded over and paperwork goes astray. We locate and test the dampers we can reach and record the ones we cannot, so you know where the gaps are. The work covers offices and schools, riser dampers and motorised smoke dampers, and the jobs we see most are dampers flagged on a fire risk assessment and dampers affected by leaks or condensation.
In smaller places like Cosham, dampers are often in the ductwork serving kitchens, plant rooms and escape routes. We plan the work around the people using the building.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a few hours for a single floor, with bigger buildings phased over more than one visit, and the area is cleaned down before we leave. A site near Cosham typically has room to park, so the questions are about access to the system and your hours.
- We plan access and timing with you first, including any out-of-hours work.
- We open up ceilings and hatches and take off each access panel.
- 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.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading
- Clear the space around the work
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then call 0345 646 2711 or drop us a line.
Advice
Do you need fire damper testing in Cosham?
Rust is a frequent reason a damper will not close. Condensation, leaks and damp plant rooms corrode the parts that need to move, and the damper can seize quietly where no one sees it.
Common reasons sites call us include:
- Fire dampers that haven’t been tested for over a year
- Fire damper items raised by an assessor
- Dampers clogged with dust or grease
- Corroded dampers in damp risers and plant rooms
If you manage a historic building in the area (Warblington Castle is about 4.4 miles east), dampers fitted during conversions can be hard to reach and need recording.

Common questions in Cosham
Which fire authority looks after Cosham?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Cosham. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
Can fire dampers in schools around Cosham be tested in the holidays?
Yes. The holidays are the usual time for school work. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Cosham, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Will we get a certificate for the dampers?
You get a test report recording every damper we tested, showing where it is, whether it passed and what we found. Keep it with your fire safety records.
What does fire damper testing cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Will we have to shut during the visit?
Not typically. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What if a fire damper will not close?
The fault is recorded and explained in the report. A repair or a replacement can follow as a remedial job with a fresh test at the end.

Different parts, different methods
Smoke dampers
If a smoke damper won’t operate when signalled, it goes on the report as a failure, with a note of what we found.
Offices and retail
In offices and retail units, dampers tend to be hidden above working areas. We can test in the evening, overnight or at weekends to keep disruption down.
What a clean won’t put right
In fairness, there are a few things this work will not fix:
- Faults in the alarm or building controls that signal smoke dampers
- Designing the building’s fire compartments
- Gaps in the wall or floor around the damper
If you are not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer.
Parts of the system we cover
- Fusible link fire dampers
- Offices and schools
- Riser dampers
- Wall and floor dampers
- Motorised smoke dampers
- Hospitals and care homes
Fire dampers in Cosham buildings
The coast is only about 1 mile from Cosham. Salt air speeds up corrosion, and corrosion is one of the things that can stop a fire damper closing. Food Standards Agency data includes about 18 schools, colleges and universities, about 32 care, childcare and hospital premises and about 6 hotels and guest houses within about 1.5 miles of central Cosham. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Hampshire and Isle of Wight Fire and Rescue Service covers Cosham. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers.
Site managers at schools such as Court Lane Junior Academy typically find the summer break the easiest time for ceiling work like damper testing. For managed buildings around Cosham station, damper testing can be booked out of hours so tenants aren’t disturbed.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
How we price fire damper testing
Your quote is based on your site. We consider:
- One-off work versus a regular cycle
- How easy every part is to reach
- How many systems or sites are involved
- Where the site is and how we reach it
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 make a difference.
What we need to know
We can often survey from photos. The most useful are:
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
Getting a quote does not take long. Send a few details and photos, 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.
