About our fire damper testing in Childs Hill
In a fire, ductwork can act as a shortcut for flame and smoke from one part of a building to the next. That depends entirely on the blade closing all the way. Annual drop testing is how you know in each part of the building. Common call-outs are for smoke dampers that need testing through their controls and fire dampers with no recent test record, on offices and schools, riser dampers and hospitals and care homes.
Across London, buildings with ducted ventilation have a fire damper wherever a duct crosses a fire-resisting wall or floor. A taller building in Childs Hill can have dampers spread across risers, plant rooms and ceiling voids.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a couple of hours for a few dampers, and a day or more across a big site. A name and number for whoever controls access to the building in Childs Hill saves time on the night.
- We plan access and timing with you first, including any out-of-hours work.
- Ceiling tiles and hatches are opened and each damper’s access panel removed.
- We release each blade and check it shuts all the way.
- We reset it and record any dirt, corrosion or damage.
- Panels and tiles go back, and the results are written up.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Advice
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Fire risk assessments, which need a fire risk assessor
- Fire alarm or control system faults behind a smoke damper
- Ductwork crossing a fire wall with no damper fitted
If you’re not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer.
Where we work
- Motorised smoke dampers
- Riser dampers
- Offices and schools
- Hospitals and care homes
- Wall and floor dampers
- Fusible link fire dampers
How we price fire damper testing
Before we fix a price, we need to know a few things. We look at:
- The times the site is available
- The number of sites or systems
- The size of the system
- A single visit or a regular plan
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Keep the damper register up to date after any building work
- Close off damper faults promptly
- Diary the annual test well ahead
- Brief other trades about dampers in ceilings and risers
The next test should be no more than a year away. The guidance is at least once a year, so it helps to book it before the date slips.
Keep a damper register: location, type, last test date and result. It means nothing gets forgotten when staff or contractors change.
What we are called out for in Childs Hill
Other trades work around dampers all the time. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
Signs it’s time to call us include:
- Corroded dampers in damp risers and plant rooms
- Fire dampers that fail to drop shut
- Fire damper items raised by an assessor
- Missing or out-of-date damper records
Healthcare buildings such as New End Hospital (about 0.9 miles east) rely on fire compartments, and the dampers in them need testing at least annually.

Fire damper testing in Childs Hill: local notes
Food Standards Agency data includes about 60 schools, colleges and universities, about 40 hospitals, care homes and childcare premises and about 17 hotels, B&Bs and guest houses across Childs Hill and its immediate surroundings (about a mile and a half). Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. London buildings tend to have dampers on several floors, so testing is usually done out of hours, a zone at a time. About 0.9 miles east of Childs Hill is New End Hospital, the nearest hospital. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed.
For schools like All Saints' CofE Primary School NW2, damper testing is easiest in the holidays, when corridors and ceilings are clear. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Heath House is about 0.7 miles east), finding every damper is the first job.

Your questions about fire damper testing in Childs Hill
Can fire dampers in schools around Childs Hill be tested in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 60 schools, colleges and universities with registered kitchens within about a mile and a half of Childs Hill. Booking early in the term gives the best choice of holiday dates.
Can parking be tricky for a job in Childs Hill?
Tell us where a van can stop near your site in Childs Hill, and about any building rules on loading. If the building has a loading slot system, we will book into it.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What paperwork do we get after testing?
After testing, we provide a report covering each damper, showing where it is, whether it passed and what we found. It belongs in your fire safety log.
How much does fire damper testing cost in Childs Hill?
There’s no set price, as it 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.
Can you test out of hours?
Yes, the visit is arranged to suit the site. Out-of-hours and weekend work is available if daytime testing would get in the way.
Is Childs Hill in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Childs Hill.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Why it’s worth doing now in Childs Hill
Faults found early are often simpler to put right. Left for years, corrosion and build-up can turn it into a full damper replacement. A busy site in Childs Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or drop us a line, and we’ll explain what it covers.
