About our fire damper testing in Tewin
A drop test is simple in principle: we release the blade, watch it close fully, then reset it. We do this for buildings in Tewin and across Hertfordshire, logging each one so the record builds year on year. If you have gaps in the fire damper test log and dust or grease build-up on damper blades, we can help, from fusible link fire dampers, riser dampers and hospitals and care homes onwards.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, where the dampers are easy to overlook. A first test normally starts with finding them all.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What fire damper testing looks like in Tewin
The FSA’s food hygiene register lists about 5 schools, colleges and universities with registered kitchens or food service within 1.5 miles or so of the middle of Tewin. Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. Tewin is covered by Hertfordshire Fire and Rescue Service. When a fire safety officer audits a non-domestic building, maintenance of systems like dampers can come up. Queen Elizabeth II Hospital is the nearest hospital, about 2.8 miles south-west of Tewin. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have.
If you manage a care home or clinic near Tewin, the testing that a hospital like Queen Elizabeth II Hospital (about 2.8 miles south-west) relies on applies to your dampers too. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Digswell House is about 2.1 miles west), finding every damper is the first job. A school like Ridgeway Academy can have any dampers tested over half-term without disturbing lessons.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Store test records alongside the fire risk assessment
- Don’t let hatches get painted shut or boarded over
- Close off damper faults promptly
- Keep to at least yearly testing
After testing, you get a report listing each of the fire and smoke dampers we tested, with where it is and whether it passed. File it with your fire safety log so it’s ready when your assessor or insurer asks.
Deal with leaks and condensation near dampers quickly. Corrosion is a common reason blades stick.
How the job changes from site to site
Offices and retail
Offices and shops often have dampers above ceilings that are rarely opened. Testing can be done outside opening hours to keep disruption down.
Schools, hospitals and care homes
Where residents can’t easily get out, holding fire and smoke back matters even more. Annual damper testing is part of keeping that in place.

Tewin questions
Can fire dampers in schools around Tewin be tested in the holidays?
Yes, holiday work suits schools best. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Tewin, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you work overnight in Tewin?
Yes. We work evenings, overnight and at weekends. The work in Tewin can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you fix fire dampers that fail?
The fault is recorded and explained in the report. We can then repair or replace the damper as a remedial job with a fresh test at the end.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What paperwork do we get after testing?
You get a test report recording every damper we tested, with its location, its result and any faults. It belongs in your fire safety log.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
What a clean will not put right
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Sign-off of the whole building’s fire safety
- Control wiring problems outside the damper itself
- Missing dampers that a designer needs to specify
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly before booking.
What the work covers
- Riser dampers
- Fusible link fire dampers
- Offices and schools
- Hospitals and care homes
- Wall and floor dampers
- Motorised smoke dampers
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes a morning or an afternoon for a small number of dampers, longer where there are many. Visits to a village like Tewin are booked in advance, at a time that suits whoever runs the site.
- First we check the schedule and the last set of results.
- We locate every damper and note any we cannot reach.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Dampers that pass are reset, and failures are logged with what we found.
- The report sets out the results, and we can quote to repair or replace failed dampers.
Getting ready for the visit
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
What affects the cost of fire damper testing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of sites or systems
- Any permits to work or inductions
- One-off work versus a regular cycle
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.

What to send for a quote:
- Any previous report or certificate
