Fire and smoke damper testing in New Malden
Our technicians work in New Malden on fire damper drop testing and smoke damper testing, with a record for each damper. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Blades that jam part-way when released
- Dampers hidden with no access panel or hatch
- Smoke dampers with no recent test
How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a morning or an afternoon for a small number of dampers, longer where there are many. Most London sites cannot stop for the day, so work in New Malden is usually done overnight, early in the morning or at weekends.
- First we check the schedule and the last set of results.
- Each damper is found and checked for access.
- Fire dampers are drop tested, and smoke dampers are tested through their controls.
- Passes are reset and any failures recorded with the reason.
- We report the results and offer remedials on failed dampers.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
- Find the previous report, if there is one
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Fire damper testing in New Malden
The point of testing is to find dampers that fail. Where a blade sticks, a link is damaged or corrosion has set in, we note it and can quote to repair or replace the damper, so the fault doesn’t just sit on a list. Typical jobs include smoke dampers that need testing through their controls and fire dampers that haven’t been tested for over a year, on offices and schools, wall and floor dampers and motorised smoke dampers.
Many London buildings have been through several fit-outs, and dampers can end up hidden above new ceilings with no access panel. In New Malden, as across London, finding every damper and recording its access is part of the job.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Keep cables and fixings away from damper blades
- Make sure access panels stay clear and usable
- Brief other trades about dampers in ceilings and risers
- Report leaks or condensation near ductwork quickly
Share the results with your fire risk assessor, so the assessment reflects where the dampers stand. Outstanding faults should be dealt with, not left on file.
Keeping to at least annual testing stops small faults turning into failed dampers. A blade that is just starting to stick is easier to deal with than a seized one.
What happens if it’s left?
Putting testing off doesn’t change whether the dampers will close; it just means you do not know. The guidance from BESA is at least once a year, so a missed year leaves a gap in the record too. For a site in New Malden, fitting the work in overnight now is far easier than closing at short notice later.
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

New Malden buildings and fire safety
There are about 24 schools, colleges and universities and about 43 care, childcare and hospital premises on the FSA’s food hygiene register in and around New Malden, up to about a mile and a half out. If any of them has ducted ventilation, its dampers need an annual drop test at least. The fire and rescue service for New Malden is London Fire Brigade. Its fire safety officers enforce the Fire Safety Order in most non-domestic buildings, and that covers fire safety systems such as dampers. Testing in London is normally done zone by zone, evenings and weekends included, so occupants are not disturbed.
A school like Christ Church New Malden CofE Primary School can have any dampers tested over half-term without disturbing lessons. Wherever there are offices above shops, near New Malden station or elsewhere in New Malden, ductwork may cross fire-resisting floors, and any dampers need testing.

What a clean won’t put right
We’d rather tell you now than book work that will not help, so here are the limits:
- Fire alarm or control system faults behind a smoke damper
- Ductwork crossing a fire wall with no damper fitted
- Sign-off of the whole building’s fire safety
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.
What the work covers
- Wall and floor dampers
- Motorised smoke dampers
- Riser dampers
- Offices and schools
- Fusible link fire dampers
- Hospitals and care homes
How the job changes from site to site
Fusible link fire dampers
The common fire damper uses a link that holds the blade open. Heat melts the link and the blade falls shut across the duct. Testing means dropping the blade, checking the full close and resetting it.
Schools, hospitals and care homes
In hospitals and care homes, people are there day and night. We plan the order of work with the site team to keep disruption to a minimum.
Questions from New Malden
Can fire dampers in schools around New Malden be tested in the holidays?
Yes, and it’s the easiest time to do it. There are about 24 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of New Malden. Send us your term dates when you call 0345 646 2711 or email us, and we will fit the work in.
What do you need to know about parking in New Malden?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Do you test smoke dampers as well?
Yes. We test smoke dampers through their control system, as they’re motor driven. Each one is checked for full travel and the result recorded.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
How do you deal with dampers that cannot be reached?
Any damper we cannot reach is listed on the report so nothing is quietly missed. Fitting an access panel is the usual fix, and we can quote to fit one.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711 or drop us a line.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Can testing be done without disrupting the building?
Yes, we plan around how the building is used. We can work evenings, overnight or at weekends where daytime access is difficult.
Common problems we fix in New Malden
Buildings in New Malden change owners, tenants and maintenance contractors over the years, and damper records often get lost along the way. Without a register, nobody knows how many dampers there are or when they were last tested.
Signs it’s time to call us include:
- Blades that jam part-way when released
- Smoke dampers that need testing through their controls
- Dirty dampers that may not close
- Dampers overdue for their annual drop test
The nearest hospital, Kingston Hospital, is about 1.2 miles north-west; healthcare buildings like it are a reminder that dampers protect people who can’t move quickly.

What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
