How we handle fire damper testing in Hounslow
Each damper we test gets a location, a result and a note of its condition. Passes are reset and left ready to work, while failures are flagged with what we found. You end up with a clear record to keep with your fire safety documents. If you’re dealing with smoke dampers with no recent test and dampers flagged on a fire risk assessment, we can put it right, from hospitals and care homes, motorised smoke dampers and wall and floor dampers onwards.
In a London area like Hounslow, testing has to fit around tenants, residents, guests or patients, so we work floor by floor or out of hours. We agree access to ceilings, risers and plant rooms with the building before we start.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

What else we do in Hounslow
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a morning or an afternoon for a small number of dampers, longer where there are many, and the area is cleaned down before we leave. A name and number for whoever controls access to the building in Hounslow saves time on the night.
- We plan access and timing with you first, including any out-of-hours work.
- We open up ceilings and hatches and take off each access panel.
- The blade is released and watched to make sure it closes fully.
- We reset it and record any dirt, corrosion or damage.
- We close everything up and send the results in a report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
- Move anything stored near the system

Hounslow questions
Who enforces fire safety at workplaces in Hounslow?
London Fire Brigade is the fire and rescue service for Hounslow. Keep each damper test report with the fire risk assessment and the building’s log book, ready to show.
Do you work at weekends in Hounslow?
Yes. We work evenings, overnight and at weekends. It means the site in Hounslow keeps running as normal. Let us know the hours you’re closed and we will book within them.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
How often do fire dampers need drop testing?
The guidance from BESA is at least annually, by a competent person. Dampers should also be tested when they’re first installed.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Do you carry out smoke damper testing?
Yes, alongside fire damper drop testing. Smoke and fire dampers are reported together, with any faults set out clearly.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Different parts, different methods
Ceiling voids and risers
Plant rooms and risers can be damp, which leads to corrosion. Signs of corrosion or water are recorded so the cause can be tackled.
Smoke dampers
A smoke damper that does not respond to its controls is recorded as a fault, with a note of what we found.
Why deal with it now?
If a damper cannot close, the wall it sits in has a hole in it during a fire. Everything else about the compartment can be right and the duct still lets it down. Testing now is how you find out before it matters. Planning ahead in Hounslow lets you pick a quiet night rather than lose a busy one.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

What affects the cost of fire damper testing
Every site gets its own quote. These are the things that affect it:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- The number of sites or systems
- What state the system is in
Whatever the type of site, the quote works 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’ll go through it with you.
What we need to know
Before you ask for a quote, gather:
- A few general shots of the system
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, phone us on 0345 646 2711, or email photos.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Fix water leaks in plant rooms and risers promptly
- File every damper report where your assessor can find it
- Add new dampers to the register as they’re fitted
- Do not let hatches get painted shut or boarded over
Put the next test in the diary within twelve months. The guidance is at least once a year, and booking the same month each year keeps it simple.
Keeping to at least annual testing stops small faults turning into failed dampers. Faults caught early are easier to fix.
Honest limits
It’s worth knowing the limits before booking:
- Deciding where dampers should be fitted
- Gaps in the wall or floor around the damper
- Fire alarm or control system faults behind a smoke damper
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly before you book.

What fire damper testing looks like in Hounslow
Food Standards Agency records list about 40 schools, colleges and universities, about 52 hospitals, care homes and childcare premises and about 13 hotels, B&Bs and guest houses registered as food businesses across Hounslow and its immediate surroundings (about a mile and a half). Many buildings of this kind have ductwork through fire-resisting walls and floors, and the dampers at those points need testing at least annually. Managed London buildings typically need damper testing booked through the agent, often out of hours. South Middlesex Hospital is the nearest hospital, about 0.9 miles south-east of Hounslow. 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.
For schools like Chatsworth Primary School, damper testing is easiest in the holidays, when corridors and ceilings are clear. If you manage an older building converted to a hotel or venue, like many historic houses in the area (Osterley House is about 1.6 miles north), finding every damper is the first job. For buildings around Hounslow station with ducted ventilation, any fire dampers need an annual test at least.
