Fire damper testing for kitchens and businesses in Chelsham
Ductwork can carry fire and smoke between compartments, and the damper is what stops it. A damper only does its job if the blade can drop fully. Regular drop testing is how that gets checked for the dampers in your building. If you have damper actions from a fire risk assessment and corroded dampers in damp risers and plant rooms, we can put it right.
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 typically starts with finding them all.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes from an hour or two in a small building to several visits on a large estate. Photos of the system and how to reach it help us plan a visit to Chelsham.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Passes are reset and any failures recorded with the reason.
- The report sets out the results, and we can quote to repair or replace failed dampers.
Preparing for the visit
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions

What fire damper testing can’t fix
We’ll always give you a straight diagnosis, so here’s what fire damper testing won’t do:
- Designing the building’s fire compartments
- Fire-stopping gaps around the duct where it passes through the wall
- Dampers that were never installed where they’re needed
If you are not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer.
What the work covers
- Riser dampers
- Fusible link fire dampers
- Offices and schools
- Wall and floor dampers
- Motorised smoke dampers
- Hospitals and care homes
What the work involves, part by part
Offices and retail
Fit-outs and tenant changes are hard on dampers. A test after the works shows the dampers still close.
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. When the link reaches its set temperature it melts, and the blade drops to close the duct. Testing means dropping the blade, checking the full close and resetting it.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What affects the cost of fire damper testing
We do not publish a price list, because sites vary so much. What we look at:
- The condition we find in the survey
- How easy every part is to reach
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
To help us quote quickly, send us:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
If you need fire damper testing in Chelsham, give us a ring on 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote normally follows within one working day.
Leave it or put it right?

Historic houses near Chelsham, with Addington Palace about 3 miles north, are a reminder that older buildings can hold dampers in unexpected places. For schools like Warlingham Village Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. Healthcare buildings such as Warlingham Park Hospital (about less than half a mile north) rely on fire compartments, and the dampers in them need testing at least annually.

Multi-site and managed buildings
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Common questions in Chelsham
Do you work at weekends in Chelsham?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just ring 0345 646 2711, or email photos with your opening times and we will plan around them.
Do you cover smaller places like Chelsham?
Yes, we work in villages as well as towns, and Chelsham is covered. Let us know about access, parking and anything unusual about getting there when you book.
Who has the duty to keep fire dampers working?
It’s the responsible person, under the Fire Safety Order 2005. Testing at least yearly and keeping the reports is how they can show it’s being done.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do you test smoke dampers as well?
Yes. Smoke dampers are motorised, so we test them by operating them through their controls. We check every blade moves fully and record the outcome.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
How often should fire dampers be tested?
The guidance from BESA is at least annually, by a competent person. Dampers should also be tested when they’re first installed.
What if a fire damper will not close?
The fault is recorded and explained in the report. We can then repair or replace the damper as a remedial job with a fresh test at the end.
