In-house cleaning or a specialist?
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 can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Fire damper testing for kitchens and businesses in Green Tye
Not every damper relies on heat. Smoke dampers are motorised and are opened and closed by a control system, so testing means running them through their controls and confirming every blade travels fully and comes back. The work covers motorised smoke dampers, hospitals and care homes and offices and schools, and common reasons people get in touch are damper actions from a fire risk assessment and dampers affected by leaks or condensation.
In rural areas, conversions, country hotels and care homes can have ductwork crossing fire-resisting walls, and the dampers in them are easily forgotten. The first visit starts by locating each damper.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Fire damper testing in Green Tye: local notes
Green Tye’s nearest hospital, Herts and Essex Hospital, is about 3.6 miles north-east. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed. The fire and rescue service for Green Tye is Hertfordshire Fire and Rescue Service. Under the Fire Safety Order, the responsible person has to keep fire safety systems, dampers included, in working order, and the fire authority enforces that in most non-domestic premises.
If you manage a care home or clinic near Green Tye, the testing that a hospital like Herts and Essex Hospital (about 3.6 miles north-east) relies on applies to your dampers too. Much Hadham Palace, about 1.3 miles north-west, is one of the historic houses near Green Tye, and older buildings converted to new uses often have ventilation added later.

How we price fire damper testing
Some jobs are bigger than they look, and some smaller. The main factors:
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before we start.
What to send for a quote
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
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.
Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Do not let anything obstruct a damper’s blade
- Tell contractors where dampers are before they start work
- Report leaks or condensation near ductwork quickly
- Book the next test before the year runs out
The next test should be no more than a year away. BESA guidance is at least annual testing, and booking the same month each year keeps it simple.
Clean ductwork means less dust and grease reaching the dampers. It makes sense to plan duct cleaning and damper testing together.

How it 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. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from a couple of hours for a handful of dampers to a full day for a large building. We agree a date with you, plan the drive to Green Tye and turn up when the site is quiet.
- 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.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Clear loose items from the work area

Related advice
What happens if it’s left?
After any fire, one of the first questions is what maintenance had been done. Damper test records are part of that answer, and they only exist if the testing happened. A fault that closes a site in a village like Green Tye affects everyone who depends on it.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Questions from Green Tye
Which fire and rescue service is responsible for Green Tye?
Green Tye is in the area of Hertfordshire Fire and Rescue Service. A report listing every damper, its location and its result is the easiest way to show the dampers are maintained.
Do you work in villages like Green Tye?
Yes, we work in villages as well as towns, and Green Tye is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Whose job is it to make sure fire dampers are tested?
It sits with the building’s responsible person. Depending on the building, that can be the employer, owner, landlord or whoever manages it. We carry out the testing and give them the records.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How often should fire dampers be tested?
The guidance from BESA is at least annually, by a competent person. A test on completion of installation comes first.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711 or email us.
Can you quote from photos?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
Different parts, different methods
Access panels
