Fire damper testing for kitchens and businesses in Lower Assendon
Each damper we test gets a location, a result and a note of its condition. Dampers that pass are reset and left open, ready to operate, while failures are flagged with what we found. That record belongs with the building’s fire safety paperwork. The work covers riser dampers, wall and floor dampers and fusible link fire dampers, and the jobs we see most are dirty dampers that may not close and rusted damper blades and springs.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. The first visit starts by locating each damper.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a couple of hours for a few dampers, and a day or more across a big site. Pictures of the system and its access let us plan the work in Lower Assendon before we set off.
- We gather what’s known about the dampers, from drawings, registers or past reports.
- Each damper is located and reached through its access panel.
- Fire dampers are drop tested and smoke dampers are run through their controls.
- We reset every damper that passes and check it’s left open.
- You get a report listing each damper, its result and any remedials needed.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
What affects the cost of fire damper testing
Before we fix a price, we need to know a few things. We check:
- Site rules, permits and inductions
- The size of the system
- One-off work versus a regular cycle
- Whether several sites go on one quote
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.
Helping us quote
When you contact us, it’s useful to have:
- Where the site is and what kind of site it is
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

FAQs for Lower Assendon
Which fire and rescue service is responsible for Lower Assendon?
That is Oxfordshire Fire and Rescue Service. If a fire safety officer audits the building, they may ask for the latest damper test records.
Is Lower Assendon within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Lower Assendon included. Let us know about access, parking and anything unusual about getting there when you book.
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?
We test, record and report, rather than certify dampers to a standard. For each damper it shows the result and anything that needs putting right.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711 or email us.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
What if a fire damper won’t close?
It’s listed on the report as a fault and we quote for remedials. After the repair, we test it again so the record shows a pass.
How the job changes from site to site
Ceiling voids and risers
Risers and service shafts often hold dampers at each floor. We work through them floor by floor so nothing is missed.
Fusible link fire dampers
For dampers closed by a spring, BESA guidance is annual testing as a minimum. A weak spring or a sticking blade shows up when the damper is dropped.
Why it’s worth doing now in Lower Assendon
An untested damper is an unknown. Testing turns it into a known pass or a known fault, with remedials offered for anything that fails, which is far easier to plan for. Our emergency line runs 24/7, but a planned visit to Lower Assendon is calmer for everyone.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711, or email photos for straight advice and a fixed quote.
