Fire damper testing in Stone, Kent

How we handle fire damper testing in Stone
The point of testing is to find dampers that fail. 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 rather than leaving you with a problem and no fix. If you’re dealing with buildings with no damper register and fire damper items raised by an assessor, we can put it right.
A building in a smaller place like Stone might have only a few dampers, but each one still needs drop testing at least once a year, with the result recorded.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Fire dampers in Stone buildings
There are about 5 schools, colleges and universities, about 17 caring premises (care homes, nurseries and hospitals) and about 4 hotels and B&Bs on the FSA’s food hygiene register across Stone and its immediate surroundings (about a mile and a half). Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Stone is covered by Kent Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. For Stone, the closest hospital is Darent Valley Hospital, roughly 1 mile south-west. Healthcare buildings rely on fire compartments to protect people who can’t easily move, and dampers keep those compartments sealed.
Wherever there are offices above shops, near Stone Crossing station or elsewhere in Stone, ductwork may cross fire-resisting floors, and any dampers need testing. If you manage a historic building in the area (Hall Place and Gardens is about 4.8 miles west), dampers fitted during conversions can be hard to reach and need recording.
Stone is about 2 miles east of Dartford, in Kent. Whether your site is in the middle of Stone or further out, fire damper testing is available to all kinds of commercial premises, from a single unit to a large public building. Stone is one of 922 places in Kent we cover for commercial clients. There’s also a page for London, roughly 16 miles from Stone.

What affects the quote in Stone
There’s no set price list, because no two systems are the same. The quote depends on:
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- How easy every part is to reach
- A single visit or a regular plan
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Helping us quote
What to send for a quote:
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, ring 0345 646 2711, or email photos.
When it’s something else
In fairness, there are a few things this work will not fix:
- Deciding where dampers should be fitted
- Ductwork crossing a fire wall with no damper fitted
- Signing off a building’s overall fire safety
If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer before booking.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Why deal with it now?
Testing every year builds a history for each damper so repeat problems show up early. A damper that was slow last year and sticks this year tells you something before it becomes a failure. Booking ahead lets us plan the trip to Stone at a time that suits you.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
Why us?
- Fully insured
- Fixed quotes from a survey or pictures
- A written report with photos after each visit
- Every job surveyed first
FAQs for Stone
Do you do school damper testing in Stone in the summer holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Stone. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Stone?
Yes. We work evenings, overnight and at weekends. That way a site in Stone does not have to lose a day’s trading. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and photos.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What if a damper has no access panel?
It goes on the report as inaccessible, with the reason. Access panels can be installed so it’s tested on the next visit.
Do we need to close while you work?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes a couple of hours for a few dampers, and a day or more across a big site. In a place like Stone, we fit the visit around your hours.
- We go through the damper schedule and any previous faults.
- We locate every damper and note any we cannot reach.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
How to prepare
- Let us know about parking and loading
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down

Advice

What else we do in Stone
When to call us in Stone
Building work often happens right next to dampers. Cables get run through them, links get knocked and blades get wedged open, and any of those can stop a damper closing.
Any of these means the system needs a check-up:
- Missing or out-of-date damper records
- Dampers that stick or will not close fully
- Smoke dampers with no recent test
- Fire dampers nobody can get to
Site managers at schools such as Stone St Mary's CofE Primary School usually find the summer break the easiest time for ceiling work like damper testing.

What the work involves, part by part
Access panels
If we can’t reach a damper, it goes on the report as inaccessible. We can fit access panels so it’s tested next time.
Smoke dampers
Smoke dampers are motorised and run by a control system. We test them through their controls and check each blade travels fully.
