Fire damper testing for kitchens and businesses in Berry's Green
Not every damper relies on heat. Smoke dampers are motorised and are opened and closed by a control system, so we test them by operating them through those controls and confirming every blade travels fully and comes back. Typical jobs include fire dampers that fail to drop shut and dampers hidden with no access panel or hatch, on motorised smoke dampers, wall and floor dampers and offices and schools.
In a London area like Berry's Green, testing has to fit around tenants, residents, guests or patients, so we work floor by floor or out of hours. Access to ceiling voids and risers is agreed with the building manager first.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Common problems we fix in Berry's Green
Dust settles on damper blades, runners and springs over the years. If the duct carries cooking vapour, a film of grease adds to it, and either can stop the blade dropping fully.
Any of these means the system needs a check-up:
- Dampers clogged with dust or grease
- Damper actions from a fire risk assessment
- Corroded dampers in damp risers and plant rooms
- Fire dampers with no recent test record
School buildings such as Cudham Church of England Primary School are normally tested in the holidays, wherever they have dampers.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
What the work involves, part by part
Access panels
Access panels sometimes get painted over, screwed shut or hidden by new ceilings. Letting us know where they are speeds the visit up.
Fusible link fire dampers
Most fire dampers are held open by a fusible link. Heat melts the link and the blade falls shut across the duct. We release the blade, check it closes fully and reset it.
Keeping the system healthy
After the visit, a few habits help the work last:
- Report leaks or condensation near ductwork quickly
- Book the next test before the year runs out
- Never wedge or tie a damper open
- Get remedials done soon after a failed test
The next test should be no more than a year away. The guidance is at least once a year, so it helps to book it before the date slips.
Where a damper sits in ductwork that collects dust or grease, keeping that ductwork clean helps. Duct cleaning and damper testing can be planned side by side.
What affects the cost of fire damper testing
We do not publish a price list, because no two systems are the same. What we look at:
- The size of the system
- Travel, parking and unloading
- How easy every part is to reach
- A single visit or a regular plan
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 you will get one fixed quote.
What we need to know
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
- Your last certificate, test record or report
- A few general shots of the system
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711, or email photos.
