About our fire damper testing in Knatts Valley
Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. Most are held open by a fusible link that melts at a set temperature, letting the blade drop and close the duct. Drop testing proves that this still happens, and we record the result for every damper we test. If you’re dealing with dampers overdue for their annual drop test and motorised smoke dampers due for testing, we can put it right.
In a village or hamlet like Knatts Valley, there may be only a few buildings with fire dampers. Each damper still needs testing at least once a year.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from a couple of hours for a handful of dampers to a full day for a large building. If you can send pictures, we can arrive in Knatts Valley knowing what to expect.
- 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.
- The blade is released and watched to make sure it closes fully.
- The damper is reset and its condition noted.
- We close everything up and send the results in a report.
Before we arrive
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about parking and loading
Getting a quote
For a fixed quote, call 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

How the job changes from site to site
Fusible link fire dampers
A damaged or painted link can stop a damper doing its job. We check its condition during the test and note anything that is not right.
Access panels
Where there’s no access panel, we record the damper as not tested and say why. We can fit access panels so it’s tested next time.
Fire dampers in Knatts Valley buildings
Kent Fire and Rescue Service covers Knatts Valley. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and keeping dampers working is part of the responsible person’s duty. Sevenoaks Hospital is the nearest hospital, about 3.9 miles south-west of Knatts Valley. Where patients or residents may need help to leave a building, working dampers matter all the more.
Hospitals such as Sevenoaks Hospital, about 3.9 miles south-west, are a good example of buildings with dampers on many floors; if you manage a clinic, surgery or care home near Knatts Valley, the same annual testing applies. Historic buildings that have had ventilation added later can hide dampers in awkward places; Lullingstone Castle, about 2.8 miles north-west, is one of the historic houses in the area around Knatts Valley. Site managers at schools such as West Kingsdown CofE VC Primary School usually find the summer break the easiest time for ceiling work like damper testing.
Knatts Valley is about 4 miles north-east of Sevenoaks, in Kent. Anywhere in TN15, we can carry out fire damper testing at your premises. Our Kent coverage runs to 922 places, and Knatts Valley is one of them. There’s also a page for Maidstone, roughly 13 miles from Knatts Valley.

Your questions about fire damper testing in Knatts Valley
Who enforces fire safety at workplaces in Knatts Valley?
Fire safety enforcement in Knatts Valley is handled by Kent Fire and Rescue Service. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Is Knatts Valley within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Knatts Valley included. Photos of the system and directions to the site help us plan the visit.
Can testing be done without disrupting the building?
Yes, we plan around how the building is used. Out-of-hours and weekend work is available if daytime testing would get in the way.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
What happens to dampers you cannot get to?
It goes on the report as inaccessible, with the reason. Access panels can be installed so it’s tested on the next visit.
Are you insured?
Yes. We are fully insured, and the details are available on request.
How long will damper testing take?
As a guide, it takes anything from a couple of hours for a handful of dampers to a full day for a large building. The number of dampers and how they’re reached decide the rest.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Fire risk assessments, which need a fire risk assessor
- Missing dampers that a designer needs to specify
- Gaps in the wall or floor around the damper
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly before you book.
Parts of the system we cover
- Wall and floor dampers
- Motorised smoke dampers
- Riser dampers
- Fusible link fire dampers
- Offices and schools
- Hospitals and care homes
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Leave it or put it right?
Sites in Knatts Valley tested every year build up a history for each damper, which shows patterns early. A damper that was slow last year and sticks this year tells you something before it becomes a failure. Rural sites can’t always move to another kitchen or room when something fails.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

What else we do in Knatts Valley
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Brief other trades about dampers in ceilings and risers
- Get remedials done soon after a failed test
- Report leaks or condensation near ductwork quickly
- Keep cables and fixings away from damper blades
Put the next test in the diary within twelve months. The guidance is at least once a year, so it helps to book it before the date slips.
Water is a damper’s enemy, so fix leaks and condensation near them promptly. Corrosion is a common reason blades stick.
