Ductwork cleaning in Shenley, Hertfordshire

- A rancid smell from the extract duct
How we handle ductwork cleaning in Shenley
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. If you have gaps where access panels were never fitted and grease pooling at the foot of the riser, we can put it right, from bends and junctions, access panels and attenuators onwards.
In a smaller place like Shenley, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Fixed quotes for ductwork cleaning in Shenley
Sites vary more than people expect. What affects the quote:
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- The scale of the work
- Working hours and out-of-hours timing
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Grease, kitchens and Shenley
The Food Standards Agency lists about 6 pubs and bars as registered food businesses in Shenley and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Shenley sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Shenley get their food hygiene inspections from Hertsmere council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Church and community hall kitchens, near Church of St Martin or anywhere around Shenley, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Shenley is Shenley Hospital, about within half a mile west. Term dates shape school work: for a school like Shenley Primary School, an extract clean fits neatly into a half-term or summer break.

Why act early in Shenley
Grease left in a duct in Shenley hardens over time. Heat and age turn it into a thick, stubborn crust, which makes each delayed clean a bigger one. Booking ahead lets us plan the trip to Shenley at a time that suits you.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Managing agents and facilities teams in Shenley
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a few hours for a short run, longer for long runs and tall risers, and we clear up before we go. For a site near Shenley, the work is booked around your opening hours, evenings and weekends included.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take photos and note any part that couldn’t be reached.
Getting ready for the visit
- Clear loose items from the work area
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, ring 0345 646 2711 or email us.

FAQs for Shenley
Will you come out to Shenley?
Yes. Shenley is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Shenley?
Yes, nights and weekends are routine for us. That way a site in Shenley does not have to lose a day’s trading. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
Can you fit access panels in our ductwork?
Yes, as part of our fits and repairs work. We place them where they help most, and we will recommend where.
How much does ductwork cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Do you have insurance?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Book the next clean before the recommended date
- Keep grease filters clean and fitted whenever you cook
- Tell us if grease leaks from the ductwork
- Keep your cleaning records together
Any section of duct we couldn’t reach is listed on the report, with the reason. We can fit access panels so those sections are cleaned next time.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Part by part
Attenuators and discharge
Some systems have attenuators to reduce noise, but they can hold grease in their linings. They’re cleaned where possible and recorded if not.
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. Visits are planned around the building’s hours, out of hours where possible.
