Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Update the register when ductwork changes
- File every damper report where your assessor can find it
- Keep cables and fixings away from damper blades
- Report leaks or condensation near ductwork quickly
Any damper that failed is listed with the reason, along with an offer to repair or replace them. Once the work is done, the damper is tested again and the record updated.
Keep a damper register: location, type, last test date and result. It stops dampers getting lost as the building changes.
About our fire damper testing in Hudnall Corner
Ductwork can carry fire and smoke between compartments, and the damper is what stops it. A damper only does its job if the blade can drop fully. Annual drop testing is how you know for the dampers in your building. The work covers offices and schools, wall and floor dampers and riser dampers, and people most often call us about dampers affected by leaks or condensation and fire dampers with no recent test record.
Rural buildings that have been converted or extended can have ducts passing through fire-resisting walls, and the dampers in them are easily forgotten. A first test usually starts with finding them all.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Hudnall Corner buildings and fire safety
There are about 4 schools, colleges and universities on the FSA’s food hygiene register within roughly a mile and a half of the centre of Hudnall Corner. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Hudnall Corner’s nearest hospital, Hemel Hempstead Hospital, is about 4.8 miles south-east. Where patients or residents may need help to leave a building, working dampers matter all the more. The fire and rescue service for Hudnall Corner is Hertfordshire Fire and Rescue Service. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order.
Healthcare buildings such as Hemel Hempstead Hospital (about 4.8 miles south-east) rely on fire compartments, and the dampers in them need testing at least annually. In Hudnall Corner, each damper is dropped to prove it closes fully, then reset.

Questions from Hudnall Corner
Is Hudnall Corner within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can a school’s dampers in Hudnall Corner be tested out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Hudnall Corner. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
Do we need to close while you work?
Not typically. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
How often should fire dampers be tested?
According to BESA guidance, dampers should be tested when they’re installed and then at least once a year. For spring-operated dampers, once a year is the minimum.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What happens if a damper fails its test?
We note the failure and what we found. We can then repair or replace the damper as a remedial job with a fresh test at the end.
Can you price the work without visiting?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What happens if it’s left?
Fire risk assessors and insurers may ask to see damper test records. Having a current report ready for a building in Hudnall Corner saves a scramble when the question comes. Rural sites cannot always move to another kitchen or room when something fails.
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.
Why us?
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Fixed quotes, usually within one working day
- One contact for all your sites in London and the South East
- Each visit written up, with photos

Different parts, different methods
Smoke dampers
If a smoke damper won’t operate when signalled, it goes on the report as a failure, along with what we saw.
Access panels
If we can’t reach a damper, it goes on the report as inaccessible. We can fit access panels so it’s tested next time.
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes from an hour or two in a small building to several visits on a large estate. Somewhere like Hudnall Corner, lanes, gates and parking are worth mentioning in advance.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- The blade is released and watched to make sure it closes fully.
- The damper is reset and its condition noted.
- We close everything up and send the results in a report.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in
