Greater London · Fire damper testing
Fire damper inspection in Northfields
Fire damper testing for Northfields, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Dampers hidden with no access panel or hatch
- Fire dampers that haven’t been tested for over a year
- Dampers that stick or won’t close fully
How we handle fire damper testing in Northfields
We are often asked to take on annual damper testing by the people who look after buildings in and around Northfields. Send us the damper schedule or the drawings if you have them, and we will plan the visit around the building’s hours. If you’re dealing with smoke dampers with no recent test and dampers that can’t be reached without an access panel, we can put it right, from fusible link fire dampers, riser dampers and hospitals and care homes onwards.
Damper testing in London buildings is normally planned around the people in them, so we work floor by floor or out of hours. Access to ceiling voids and risers is agreed with the building manager first.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

How it works
We turn up 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 few hours for a single floor, with bigger buildings phased over more than one visit. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Northfields.
- Before the visit, we agree access, timings and any areas with restrictions.
- We open up ceilings and hatches and take off each access panel.
- We release each blade and check it shuts all the way.
- We reset it and record any dirt, corrosion or damage.
- Panels and tiles go back, and the results are written up.
Before we arrive
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, phone us on 0345 646 2711 or email us.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Missing dampers that a designer needs to specify
- Faults in the alarm or building controls that signal smoke dampers
- Signing off a building’s overall fire safety
If you’re not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer before booking.
Parts of the system we cover
- Riser dampers
- Hospitals and care homes
- Motorised smoke dampers
- Wall and floor dampers
- Offices and schools
- Fusible link fire dampers
Signs you need fire damper testing in Northfields
Building work often happens right next to dampers. A cable run through the blade path, a knocked link or a wedged blade is enough to stop a damper closing.
Signs it’s time to call us include:
- Gaps in the fire damper test log
- Damper actions from a fire risk assessment
- Dampers hidden with no access panel or hatch
- Dirty dampers that may not close
If you manage a care home or clinic near Northfields, the testing that a hospital like Ealing Hospital (about 1.4 miles west) relies on applies to your dampers too.
Before you book anyone
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether a survey comes first
Northfields: your questions answered
Can fire dampers in schools around Northfields be tested in the holidays?
Yes, holiday work suits schools best. With about 53 schools and colleges on the FSA’s register within roughly a mile and a half of Northfields, it pays to plan holiday dates ahead. Just phone us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Does London parking affect a job in Northfields?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
What happens to dampers you cannot get to?
It goes on the report as inaccessible, with the reason. Access panels can be installed so the damper can be tested next time.
Do you test dampers in the evening or at weekends?
Yes, we plan around how the building is used. Out-of-hours and weekend work is available where daytime access is difficult.
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.
Are you insured?
Yes. We are fully insured, and the details are available on request.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Is TR19 cleaning required by law?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
What the work involves, 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.
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 so care is not interrupted.

What else we do in Northfields
Why act early in Northfields
Testing every year builds a history for each damper so repeat problems show up early. If the same damper keeps giving trouble, the record shows it long before it fails outright. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why choose Duct Doctor in Northfields
- Every job surveyed first
- A fixed price before any work starts
- A single point of contact for sites across the South East and London
- Out-of-hours work and a 24/7 emergency line
Fixed quotes for fire damper testing in Northfields
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Whether several sites go on one quote
- Any permits to work or inductions
- The size of the system
- One-off work versus a regular cycle
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- A few general shots of the system
- Where the site is and what kind of site it is
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Northfields and across Greater London. Larger estates can be phased building by building around the people who use them.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Fire dampers in Northfields buildings
Food Standards Agency records list about 53 schools, colleges and universities, about 81 hospitals, care homes and childcare premises and about 13 hotels and guest houses registered as food businesses within 1.5 miles or so of the middle of Northfields. Larger buildings like these are often divided into fire compartments, with dampers where ducts pass between them. Northfields’s nearest hospital, Ealing Hospital, is about 1.4 miles west. Where patients or residents may need help to leave a building, working dampers matter all the more. Ceiling voids and risers in London buildings can hold many dampers, and each one has to be reached and recorded.
Wherever there are offices above shops, near Brentford station or elsewhere in Northfields, ductwork may cross fire-resisting floors, and any dampers need testing. If you manage a historic building in the area (Boston Manor is about 0.5 miles south), dampers fitted during conversions can be hard to reach and need recording.
