Why act early in Letchworth Garden City
If a damper cannot close, the wall it sits in has a hole in it during a fire. Everything else about the compartment can be right and the duct still lets it down. It’s far better to find that out on a test than in a fire. Nothing in a duct, damper or fan improves by being left.

Fire damper testing in Letchworth Garden City
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. Common call-outs are for damper actions from a fire risk assessment and buildings with no damper register, on wall and floor dampers, hospitals and care homes and motorised smoke dampers.
In a town like Letchworth Garden City, the buildings with fire dampers tend to be schools, offices, surgeries, care homes, hotels and blocks of flats. Any building with ductwork through fire-resisting walls or floors should have its dampers tested at least annually.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning does not 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.
Questions from Letchworth Garden City
Do you do school damper testing in Letchworth Garden City in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Letchworth Garden City. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work overnight in Letchworth Garden City?
Yes, we can come after you close and finish before you open. That way a site in Letchworth Garden City does not have to lose a day’s trading. Your opening times are the first thing we ask for.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Whose job is it to make sure fire dampers are tested?
It sits with the building’s responsible person. That’s often the employer, owner, landlord, facilities manager or managing agent. Our part is the testing and the records that show it’s been done.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How do you deal with dampers that cannot be reached?
Any damper we cannot reach is listed on the report so nothing is quietly missed. Fitting an access panel is the usual fix, and we can quote for it.
Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a morning or an afternoon for a small number of dampers, longer where there are many. Send us pictures of the system and we can plan most of a visit in Letchworth Garden City before we arrive.
- 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.
- We report the results and offer remedials on failed dampers.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time
Get a fixed quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Offices and retail
In offices and retail units, dampers tend to be hidden above working areas. We can test in the evening, overnight or at weekends to keep disruption down.
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.
When it’s something else
Before you book, it helps to know what’s not included:
- Designing the building’s fire compartments
- Fire-stopping gaps around the duct where it passes through the wall
- Ductwork crossing a fire wall with no damper fitted
If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
