Why it’s worth doing now in Arnos Grove
Faults found early are often simpler to put right. Years of corrosion and dirt can mean the whole damper needs replacing instead. Leaving it on a busy London site only adds to the work.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

How we handle fire damper testing in Arnos Grove
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. Regular drop testing is how that gets checked in each part of the building. Common call-outs are for rusted damper blades and springs and blades that jam part-way when released, on hospitals and care homes, offices and schools and wall and floor dampers.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. In a larger building in Arnos Grove, that can mean dampers on every floor, many of them above ceilings or in risers.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Report leaks or condensation near ductwork quickly
- Do not let anything obstruct a damper’s blade
- Diary the annual test well ahead
- Update the register when ductwork changes
Any damper that failed is listed with the reason, and we can quote for remedials. After a repair, we retest the damper and update the record.
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.
When something else is needed
A few issues sit outside what this work can do:
- Missing dampers that a designer needs to specify
- Holes around ductwork in fire-resisting walls
- Deciding where dampers should be fitted
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly before you book.

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a morning or an afternoon for a small number of dampers, longer where there are many. Most London sites can’t stop for the day, so work in Arnos Grove is usually done overnight, early in the morning or at weekends.
- We go through the damper schedule and any previous faults.
- Each damper is found and checked for access.
- We test fire dampers by dropping them and smoke dampers by operating them through the controls.
- Passes are reset and any failures recorded with the reason.
- The report sets out the results, and we can quote to repair or replace failed dampers.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend

Advice
Your questions about fire damper testing in Arnos Grove
Which fire and rescue service is responsible for Arnos Grove?
It’s London Fire Brigade, which covers Arnos Grove. BESA guidance is that every fire damper is tested at least once a year, so an officer or insurer may expect a report less than a year old.
Can you test school fire dampers in Arnos Grove out of term?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 42 schools, colleges and universities with registered kitchens within about a mile and a half of Arnos Grove. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
What happens if a damper fails its test?
The fault is recorded and explained in the report. We can then repair or replace the damper as a remedial job and test it again.
Do you test smoke dampers as well?
Yes. Every smoke damper is driven through its controls and checked for full movement. If someone else looks after the controls, we plan the timing with you.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Whose job is it to make sure fire dampers are tested?
The Regulatory Reform (Fire Safety) Order 2005 puts it on the responsible person. Annual testing by a competent person, with written records, is a practical way to show the duty is being met.
How often do fire dampers need drop testing?
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.
Part by part
Smoke dampers
A smoke damper is opened and closed by a motor, not a link. Testing means operating them from the controls and check each blade travels fully.
Ceiling voids and risers
Ceiling voids are where lots of dampers end up. We lift tiles where needed and put them back as we found them.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
