Fire damper testing in Hatfield Hyde, done properly
Wherever a duct crosses a fire-resisting wall or floor, there should be a fire damper inside it. A fusible link holds the blade open until heat melts it, and the blade then drops to shut the duct. Drop testing proves that this still happens, and we record the result for every damper we test. The work covers wall and floor dampers, riser dampers and hospitals and care homes, and the jobs we see most are fire damper items raised by an assessor and dampers clogged with dust or grease.
In a smaller place like Hatfield Hyde, buildings with fire dampers are more likely to be a school, a surgery, a care home or a hotel than an office block. The duty to keep them working is the same as in a city.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Signs you need fire damper testing in Hatfield Hyde
Other trades work around dampers all the time. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
The symptoms we’re asked about most are:
- Buildings with no damper register
- Dampers affected by leaks or condensation
- Smoke dampers that need testing through their controls
- Fire dampers that fail to drop shut
Hatfield House, about 1.7 miles south-west, is one of the historic houses near Hatfield Hyde, and older buildings converted to new uses often have ventilation added later.

What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a couple of hours for a few dampers, and a day or more across a big site. Your opening hours decide when we come to Hatfield Hyde, not ours.
- 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.
Before we arrive
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or drop us a line.

Common questions in Hatfield Hyde
Can a school’s dampers in Hatfield Hyde be tested out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around Hatfield Hyde, the Food Standards Agency lists about 16 schools and colleges with registered kitchens within a mile and a half or so. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Do you work in villages like Hatfield Hyde?
Yes, Hatfield Hyde is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What paperwork do we get after testing?
What you receive is a written report of each test for every damper on the visit. Failures are set out with the remedials we’d suggest.
Can you look after several 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.
How long does fire damper testing take?
It takes a couple of hours for a few dampers, and a day or more across a big site. How easily we can reach the dampers makes the most difference, so we will confirm the time when we quote.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
In-house cleaning or a specialist?
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.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
When it’s something else
We’d rather tell you now than book work that will not help, so here are the limits:
- Dampers that were never installed where they’re needed
- Sign-off of the whole building’s fire safety
- Faults in the alarm or building controls that signal smoke dampers
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think before you book.
Where we work
- Fusible link fire dampers
- Motorised smoke dampers

What affects the cost of fire damper testing
There’s no set price list, because sites vary so much. What we look at:
- The times the site is available
- The condition of the system
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
When you contact us, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
To get a fixed quote, phone us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Part by part
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.
Ceiling voids and risers
Where ductwork runs up through a building, there are often dampers at every floor. We work through them floor by floor so nothing is missed.
