Fire damper testing in Letchmore Heath, done properly
Testing finds the dampers that will not close. When one sticks, has a damaged link or is corroded, we report it and offer remedials, so the fault does not just sit on a list. If you’re dealing with smoke dampers that need testing through their controls and fire dampers with no recent test record, we can help.
In a village or hamlet like Letchmore Heath, there may be only a few buildings with fire dampers. Each damper still needs testing at least once a year.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What affects the cost of fire damper testing
A fixed price needs a few facts first. We check:
- The condition we find in the survey
- A single visit or a regular plan
- The size of the system
- Any permits to work or inductions
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.
Helping us quote
We can often survey from photos. Try to include:
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- Your last certificate, test record or report
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

What we do, step by step
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 job takes a morning or an afternoon for a small number of dampers, longer where there are many. The timing of a visit to Letchmore Heath is set by you, and the travel is our side of the planning.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- We release each blade and check it shuts all the way.
- We reset it and record any dirt, corrosion or damage.
- We close everything up and send the results in a report.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions

Food Standards Agency records list about 12 schools, colleges and universities and about 3 hotels, B&Bs and guest houses registered as food businesses within about 1.5 miles of central Letchmore Heath. Buildings like these often have ducted ventilation, and wherever a duct crosses a fire-resisting wall or floor there should be a damper, tested at least once a year. Shenley Hospital is the nearest hospital, about 2.6 miles north-east of Letchmore Heath. Where patients or residents may need help to leave a building, working dampers matter all the more. Letchmore Heath is covered by Hertfordshire Fire and Rescue Service.

How the job changes from site to site
Ceiling voids and risers
Risers and service shafts often hold dampers at each floor. Testing goes floor by floor so each one is accounted for.
Fusible link fire dampers
For dampers closed by a spring, BESA guidance is annual testing as a minimum. Dropping the blade reveals springs that are tired and blades that drag.
Letchmore Heath: your questions answered
Do you work at weekends in Letchmore Heath?
Yes, evening, overnight and weekend work is normal for us. It means the site in Letchmore Heath keeps running as normal. When you call 0345 646 2711 or email us, mention when the site is quiet.
Is Letchmore Heath within the area you cover?
Yes. Letchmore Heath is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will we have to shut during the visit?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
How do you deal with dampers that can’t be reached?
The report lists each inaccessible damper and where it is, so you know exactly what’s outstanding. An access panel tends to solve it, and we can quote for it.
How often does BESA say fire dampers should 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 about areas you cannot get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
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.
Common problems we fix in Letchmore Heath
Dust settles on damper blades, runners and springs over the years. If the duct carries cooking vapour, a film of grease adds to it, and either can stop the blade dropping fully.
These are the problems we see most often:
- Fire damper items raised by an assessor
- Fire dampers that fail to drop shut
- Fire dampers with no recent test record
- Dampers clogged with dust or grease
A school like Fair Field Junior School can have any dampers tested over half-term without disturbing lessons.
What to look for in a quote
- Whether the figure could change on the day
- If they look at the system before pricing
- Exactly which parts of the system are covered
- What hours they’ll be on site
What fire damper testing can’t fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Faults in the alarm or building controls that signal smoke dampers
- Missing dampers that a designer needs to specify
- Sign-off of the whole building’s fire safety
If you are not sure, just call us on 0345 646 2711, or email photos and we’ll give you a straight answer.
