Ductwork cleaning in Heston, done properly
If the ducts in Heston haven’t been cleaned for a while, or nobody is sure when they were? A few details about the system are a good start when you ring 0345 646 2711 or drop us a line, and we will send you a fixed quote for ductwork cleaning, usually within one working day. We’re often asked to deal with a rancid smell from the extract duct and hardened, baked-on grease in long horizontal runs, across attenuators, multi-storey ducts and bends and junctions.
Kitchens in Heston, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
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’re fully insured.

What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Why it’s worth doing now in Heston
TR19® isn’t law, but the duty to manage fire risk is. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, including the grease inside the extract ductwork. Leaving it on a busy London site only adds to the work.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before work begins.

How the job changes from site to site
Attenuators and discharge
The last section of duct before the discharge is often the coolest, so it can collect more grease than expected. We include it in the clean and the readings.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Heston: your questions answered
Is parking a problem for work in Heston?
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 normally gets round them.
Who would carry out a food hygiene inspection at a kitchen in Heston?
Food hygiene inspections in Heston are carried out by Hounslow council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you clean ductwork with no access panels?
Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
Common problems we fix in Heston
Many ducts do not have enough access panels. Sections between panels go uncleaned, sometimes since the system was installed, and the grease there keeps building out of sight.
Most sites get in touch after spotting something like this:
- A duct clean needed for an insurer
- Duct runs with no cleaning record
- Grease seeping out of the duct seams
- Hardened, baked-on grease in long horizontal runs
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Heston is Hounslow Hospital, about 1.2 miles south.

How we price ductwork cleaning
You’ll get a fixed price before work begins. It’s based on:
- What state the system is in
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
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 make a difference.
What we need to know
What to send for a quote:
- Your opening hours and when the area is out of use
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
If you need ductwork cleaning in Heston, ring 0345 646 2711 or email us. Let us know the site type and the opening hours, and send photos or your last report if you can. We usually send a fixed quote within one working day.
How it works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours to more than one visit, depending on duct length and access. In Heston, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- We start by working out how the duct runs and where it can be opened.
- Grease readings are taken at set points along the duct.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Clear the space around the work
- Let us know about permits to work or site inductions
Ask for a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711, or send details by email.

When something else is needed
Ductwork cleaning can’t fix everything, and we’d rather say so up front. It will not put right:
- An extract fan that has stopped working
- Duct sealed behind fixed ceilings or walls
- Undersized or badly laid-out ducts
If you are not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer.

Kitchen extracts in Heston
Food Standards Agency records list about 275 cafés, restaurants and staff canteens and about 124 takeaways and sandwich shops in Heston and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. Most London extract cleaning happens at night, after the last service. Kitchens in Heston get their food hygiene inspections from Hounslow council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
A hall kitchen that only cooks for events, whether near St Leonard's Church or elsewhere in Heston, still needs its extract cleaned, just less often. School kitchens, at schools like Westbrook Primary School for example, are typically cleaned in the holidays so no lunches are lost.
