Mapesbury: your questions answered
Can you test school fire dampers in Mapesbury out of term?
Yes. The holidays are the usual time for school work. Around Mapesbury, the Food Standards Agency lists about 33 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Which fire service covers Mapesbury?
It’s London Fire Brigade, which covers Mapesbury. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Is a quote from photos possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Is TR19 a legal requirement?
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 many insurers can refuse or reduce a claim without proof of cleaning.
About our fire damper testing in Mapesbury
For every damper, we record where it is, whether it passed and the state it’s in. Dampers that pass are reset and left open, ready to operate, while failures are flagged with what we found. That record belongs with the building’s fire safety paperwork. Common call-outs are for rusted damper blades and springs and dust or grease build-up on damper blades, across wall and floor dampers, offices and schools and hospitals and care homes.
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.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the visit works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a morning or an afternoon for a small number of dampers, longer where there are many. For a job in Mapesbury, tell us about loading bays, permits, lifts and roof access when you book.
- First we look at any damper register, drawings or earlier test reports.
- We find every damper and open it up through the access panel.
- Fire dampers are drop tested and smoke dampers are run through their 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
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool

Mapesbury buildings and fire safety
Going by the FSA’s register, there are about 33 schools, colleges and universities, about 63 care, childcare and hospital premises and about 7 hotels and guest houses serving food within about 1.5 miles of central Mapesbury. Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Mapesbury’s nearest hospital, Neasden Hospital, is about 0.9 miles east. A hospital is the kind of building where dampers sit on every floor, and clinics, surgeries and care homes need the same annual testing for any they have. London buildings tend to have dampers on several floors, so testing is usually done out of hours, a zone at a time.
The nearest hospital, Neasden Hospital, is about 0.9 miles east; healthcare buildings like it are a reminder that dampers protect people who cannot move quickly. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Pitzhanger Manor is about 3 miles south), finding every damper is the first job.
Mapesbury is about 1 mile south-east of Wembley, in Greater London. Across the HA9 area, we can take on fire damper testing. Mapesbury is one of 764 places in Greater London where we work for fire damper testing. London is in our area too, around 9 miles away.
Every address in HA9, HA0 and NW10 is within our area for fire damper testing, from the main roads to the quietest streets. Whether your site is on London Road, Harrow Road and Cecil Avenue or a nearby road, we can help. If your site is just outside Mapesbury, we cover Tokyngton (1 mile south-east), Stonebridge Park (1 mile south-east), Wembley Park (1 mile north), Wembley (1 mile north-west) and Brent Park (1 mile east). Within a short drive, we also cover London (9 miles south-east), City of Westminster (6 miles south-east), Marylebone (6 miles east), Kensington (5 miles south-east), St Pancras (7 miles east) and Shoreditch (9 miles east).
What’s near Mapesbury
Locally, jobs take us to businesses close to The Swaminarayan School, Hilton London Wembley pub and St. Raphael's Edible Garden and the streets around them. Mapesbury has its own railway station: Wembley Stadium station. Other landmarks nearby include Brent Museum and Archives (2.2 miles east) and Neasden Hospital (0.9 miles east). Green spaces nearby include Fox Wood and Middle Lake.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
What affects the quote in Mapesbury
The quote reflects the site in front of us. We consider:
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- How many systems or sites are involved
- The scale of the work
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then ring 0345 646 2711 or send us an email.
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Keep ceiling hatches and duct panels easy to open
- Tell contractors where dampers are before they start work
- Report leaks or condensation near ductwork quickly
- File every damper report where your assessor can find it
Any damper that failed is listed with the reason, along with an offer to repair or replace them. After a repair, we retest the damper and update the record.
A simple register of every damper helps a great deal: where each damper is, what kind it is and when it was last tested. It stops dampers getting lost as the building changes.
What fire damper testing cannot fix
To be straight with you, some problems need a different fix:
- Holes around ductwork in fire-resisting walls
- Designing the building’s fire compartments
- Ductwork crossing a fire wall with no damper fitted
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
What the work covers
- Motorised smoke dampers
- Offices and schools
- Wall and floor dampers
- Riser dampers
- Hospitals and care homes
- Fusible link fire dampers
When to call us in Mapesbury
Rust is a frequent reason a damper will not close. Condensation, leaks and damp plant rooms corrode the parts that need to move, so a damper can seize without anyone noticing.
Signs it’s time to call us include:
- Dampers affected by leaks or condensation
- Dampers overdue for their annual drop test
- Dampers that can’t be reached without an access panel
- Damper actions from a fire risk assessment
If you look after a building near Wembley Stadium station with a fire risk assessment due, a damper test with a full record is worth having first.
Questions to ask before you book
- Whether a survey comes first
- Whether the quote shows VAT
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the price is fixed

How the job changes from site to site
Offices and retail
Each new fit-out brings a risk of damaged or covered dampers. A test after the works shows the dampers still close.
Smoke dampers
Because they’re linked to controls, smoke damper tests can need some coordination. We plan that with you before the visit.
