Fire damper testing in Northumberland Heath, Greater London
One call covers fire damper drop testing and smoke damper testing, with a record for each damper in Northumberland Heath: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Fire dampers that haven’t been tested for over a year
- Dust or grease build-up on damper blades
- Damper actions from a fire risk assessment
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a couple of hours for a few dampers, and a day or more across a big site. For a job in Northumberland Heath, tell us about loading bays, permits, lifts and roof access when you book.
- We start with whatever records exist: registers, drawings or old reports.
- Each damper is located and reached through its access panel.
- Every fire damper is dropped, and every smoke damper is tested through its controls.
- Dampers that close fully are reset and left open.
- The results go into a report, with failed dampers and remedials listed.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

About our fire damper testing in Northumberland Heath
Smoke dampers work differently from fire dampers. A smoke damper is driven by a motor and responds to signals from its controls, so we test them by operating them through those controls and checking that each blade moves fully and returns. Common call-outs are for motorised smoke dampers due for testing and fire dampers with no recent test record, on motorised smoke dampers, offices and schools and hospitals and care homes.
London’s offices, hotels, hospitals and blocks of flats are full of ductwork crossing fire-resisting walls and floors. A taller building in Northumberland Heath can have dampers spread across risers, plant rooms and ceiling voids.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Common questions in Northumberland Heath
Which fire and rescue service is responsible for Northumberland Heath?
It’s London Fire Brigade, which covers Northumberland Heath. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Is parking a problem for work in Northumberland Heath?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you carry out smoke damper testing?
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.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
How much does fire damper testing cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll typically reply within one working day.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

What else we do in Northumberland Heath
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How the job changes from site to site
Offices and retail
In shared buildings, some dampers sit inside tenants’ space. Access to each area is planned with whoever manages the building.
Access panels
A damper can only be tested if it can be reached. Most need an access panel in the duct and a hatch in the ceiling or wall.
When it’s something else
It’s worth knowing the limits before booking:
- Fire risk assessments, which need a fire risk assessor
- Fire-stopping gaps around the duct where it passes through the wall
- Missing dampers that a designer needs to specify
If you’re not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer.

Do you need fire damper testing in Northumberland Heath?
Building work often happens right next to dampers. Cables get run through them, links get knocked and blades get wedged open, and any of those can stop a damper closing.
Most sites get in touch after spotting something like this:
- Fire dampers with no recent test record
- Blades that jam part-way when released
- Dust or grease build-up on damper blades
- Damper actions from a fire risk assessment
Historic houses near Northumberland Heath, with Hall Place and Gardens about 1.8 miles south, are a reminder that older buildings can hold dampers in unexpected places.

How we price fire damper testing
The quote reflects the site in front of us. We consider:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- What state the system is in
- Parking and loading at the site
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
What to send for a quote:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then call 0345 646 2711 or email us.
