Perivale: your questions answered
Do you test dampers in schools in Perivale during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 35 schools, colleges and universities with registered kitchens within about a mile and a half of Perivale. Booking early in the term gives the best choice of holiday dates.
What do you need to know about parking in Perivale?
A loading bay, a visitor permit or off-street space near the site in Perivale makes the visit easier to plan. Much of our London work is done overnight, which helps.
What does fire damper testing cost?
Every site is different, so each gets its own fixed quote. To get one, call us on 0345 646 2711 or send us an email and tell us about the site and its opening hours.
What paperwork do we get after testing?
You get a test report recording every damper we tested, showing where it is, whether it passed and what we found. It belongs in your fire safety log.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Can you quote from pictures?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you test dampers in the evening or at weekends?
Yes. Evenings, nights and weekends are all possible, so the building keeps running. Tell us the hours that suit and we will plan around them.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
About our fire damper testing in Perivale
Each damper we test gets a location, a result and a note of its condition. Dampers that pass are reset and left open, ready to operate, while failures are flagged with what we found. You end up with a clear record to keep with your fire safety documents. If you have missing or out-of-date damper records and dust or grease build-up on damper blades, we can help, from hospitals and care homes, fusible link fire dampers and motorised smoke dampers onwards.
In a London area like Perivale, testing has to fit around tenants, residents, guests or patients, so we work floor by floor or out of hours. Access to ceiling voids and risers is agreed with the building manager first.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Why it’s worth doing now in Perivale
Putting testing off doesn’t change whether the dampers will close; it just means you don’t know. BESA guidance is to test at least annually, so a missed year leaves a gap in the record too. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
No two sites are the same, 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.
Why choose Duct Doctor in Perivale
- Photo reports with every job
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- CHAS, SafeContractor and ISO 9001
- Every job surveyed first
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: 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.
Common problems we fix in Perivale
Corrosion is another common cause of failure. Condensation, leaks and damp plant rooms corrode the parts that need to move, so a damper can seize without anyone noticing.
What we’re most often called out for:
- Fire dampers with no recent test record
- Damper actions from a fire risk assessment
- Buildings with no damper register
- Rusted damper blades and springs
If you look after a building near South Greenford station with a fire risk assessment due, a damper test with a full record is worth having first.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote is based on a survey or photos
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from an hour or two in a small building to several visits on a large estate, and the area is cleaned down before we leave. Loading bays, visitor permits and roof access are the first things we ask about for a site in Perivale.
- We gather what’s known about the dampers, from drawings, registers or past reports.
- We find every damper and open it up through the access panel.
- Every fire damper is dropped, and every smoke damper is tested through its controls.
- We reset every damper that passes and check it’s left open.
- The results go into a report, with failed dampers and remedials listed.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Clear loose items from the work area

What else we do in Perivale
What fire damper testing can’t fix
Fire damper testing cannot fix everything, and we will tell you before we start. It won’t put right:
- Sign-off of the whole building’s fire safety
- Designing the building’s fire compartments
- Holes around ductwork in fire-resisting walls
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- Fusible link fire dampers
- Motorised smoke dampers
- Offices and schools
- Wall and floor dampers
- Hospitals and care homes
- Riser dampers
What affects the quote in Perivale
We quote each job individually. These are the things that affect it:
- How easy every part is to reach
- How many systems or sites are involved
- Where the site is and how we reach it
- The condition we find in the survey
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
What to send for a quote
We can often survey from pictures. The most useful are:
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
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 photos, get a survey first. Either way, the quote is fixed before any work is booked.
Perivale buildings and fire safety
Going by the FSA’s register, there are about 35 schools, colleges and universities and about 71 caring premises (care homes, nurseries and hospitals) serving food across Perivale and its immediate surroundings (about a mile and a half). Schools, care settings and hotels are the kind of buildings where fire dampers are commonly found. The fire and rescue service for Perivale is London Fire Brigade. In most workplaces and other non-domestic buildings, it’s the fire and rescue authority that enforces the Fire Safety Order. Clementine Churchill Hospital is the nearest hospital, about 1.9 miles north of Perivale. Healthcare buildings rely on fire compartments to protect people who cannot easily move, and dampers keep those compartments sealed.
A school like St John Fisher Catholic Primary School can have any dampers tested over half-term without disturbing lessons. Historic buildings that have had ventilation added later can hide dampers in awkward places; Pitzhanger Manor, about 2 miles south, is one of the historic houses in the area around Perivale.
