About our fire damper testing in Allen's Green
The idea behind drop testing is straightforward: the blade is released, checked for a full close and reset. We test dampers for sites in Allen's Green and the rest of Hertfordshire, keeping a log for each damper so there’s a history to look back on. The work covers offices and schools, motorised smoke dampers and fusible link fire dampers, and common reasons people get in touch are motorised smoke dampers due for testing and dampers flagged on a fire risk assessment.
Somewhere as small as Allen's Green, fire dampers are usually found in a school, a care home, a hotel or a converted building, wherever there is one. Each damper still needs testing at least once a year.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why it’s worth doing now in Allen's Green
Sites in Allen's Green 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. Planning a trip to Allen's Green ahead is easier for everyone than a rushed one.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

What else we do in Allen's Green
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Book the next test before the year runs out
- Store test records alongside the fire risk assessment
- Report leaks or condensation near ductwork quickly
- Add new dampers to the register as they’re fitted
Make sure trades working in ceilings and risers know where the dampers sit, and that they mustn’t tie, wedge or obstruct them. If a damper has been disturbed, have it tested again.
Water is a damper’s enemy, so fix leaks and condensation near them promptly. Corrosion is a common reason blades stick.
What affects the cost of fire damper testing
Some jobs are bigger than they look, and some smaller. The main factors:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- The condition of the system
- Travel, parking and unloading
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.
Helping us quote
To help us quote quickly, please include:
- When the site is open and when it’s quiet
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Common problems we fix in Allen's Green
Buildings in Allen's Green change owners, tenants and maintenance contractors over the years, and the damper records don’t always go with them. Without a register, nobody knows how many dampers there are or when they were last tested.
Clients usually contact us after spotting something like this:
- Dampers flagged on a fire risk assessment
- Fire dampers with no recent test record
- Dampers that cannot be reached without an access panel
- Rusted damper blades and springs
If you manage an older building converted to a hotel or venue, like many historic houses in the area (Much Hadham Palace is about 2.2 miles north-west), finding every damper is the first job.

FAQs for Allen's Green
Can you come to Allen's Green after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Allen's Green doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Is Allen's Green within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Allen's Green included. The journey is planned ahead, so a few details about the route help.
Who has the duty to keep fire dampers working?
It sits with the building’s responsible person. Depending on the building, that can be the employer, owner, landlord or whoever manages it. Our part is the testing and the records that show it’s been done.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
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 the site can carry on as normal.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
Can you test motorised smoke dampers?
Yes. Smoke dampers are motorised, so we test them by operating them through their controls. Each one is checked for full travel and the result recorded.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
What the work involves, part by part
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. Heat melts the link and the blade falls shut across the duct. Testing means dropping the blade, checking the full close and resetting it.
Schools, hospitals and care homes
Where residents cannot easily get out, holding fire and smoke back matters even more. Regular damper testing supports that.

We agree a date with you, plan the drive to Allen's Green and turn up when the site is quiet.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
