About our ductwork cleaning in Little Marlow
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that’s where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. If you have fat dripping from the ductwork and a grease test showing the duct is overdue, we can put it right.
In a small place like Little Marlow, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What affects the cost of ductwork cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether several sites go on one quote
- One-off work versus a regular cycle
- How easy every part is to reach
- Working hours and out-of-hours timing
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
We can often survey from photos. The most useful are:
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Then call 0345 646 2711, or email photos.

FAQs for Little Marlow
Can a school canteen extract in Little Marlow be done out of term time?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Little Marlow. Booking early in the term gives the best choice of holiday dates.
Which environmental health team covers Little Marlow?
In Little Marlow, it’s Buckinghamshire council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
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. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Can you fit access panels in our ductwork?
Yes, we do. We’ll point out where panels are needed, and we can fit them so those sections are cleaned in future.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Do we have to stop cooking while the ducts are cleaned?
When the kitchen is closed. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What we’re called out for in Little Marlow
Slow air leaves the most grease behind. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Look out for any of the following:
- Fat dripping from the ductwork
- Heavy grease at the base of a riser
- Years of grease along the duct floor
- Duct runs that cannot be reached
A hospital like Marlow Community Hospital, about 1.5 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before booking
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
- Exactly which parts of the system are covered
- Whether the quote is based on a survey or photos
Landlords, agents and facilities managers
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.
We also work for facilities teams across offices, schools and healthcare across Buckinghamshire. Larger estates can be phased building by building around the people who use them.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Never cook with a filter missing
- Leave a way through to the access panels
- Ask us about extra access panels where sections can’t be reached
- Tell us if grease leaks from the ductwork
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Waste grease and water are taken away.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
How the visit works
Night work is normal for us. 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 anything from a few hours to several visits, depending on the length of duct. Seeing the system in pictures first means the trip to Little Marlow can be planned properly.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Getting ready for the visit
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions

Advice
Kitchen extracts in Little Marlow
The FSA’s food hygiene register includes about 15 pubs, bars and clubs and about 3 hotels and B&Bs within 1.5 miles or so of the middle of Little Marlow. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Buckinghamshire Fire and Rescue Service covers Little Marlow. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. In Little Marlow, food businesses are inspected by environmental health officers from Buckinghamshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Cliveden, about 2.9 miles south-east, is one of the historic houses near Little Marlow; if you run event catering at a venue like that, cleans can be booked between functions. Term dates shape school work: for a school like Little Marlow CofE School, an extract clean fits neatly into a half-term or summer break.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning won’t do:
- Ductwork that was poorly designed
- Fire dampers that don’t close (they need testing and remedials)
- A failed fan motor at the end of the duct (a fan repair job)
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Vertical risers
- Bends and junctions
- Multi-storey ducts
- Attenuators
- Horizontal duct runs
- Access panels
What the work involves, part by part
Attenuators and discharge
The last section of duct before the discharge is often the coolest, so it can collect more grease than expected. It’s tested and cleaned along with the rest.
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. We agree a sequence that suits the building, out of hours where possible.
