Ductwork cleaning for kitchens and businesses in Chilswell
Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Cleaning the duct takes that fuel away. We’re often asked to deal with thick deposits at the bottom of a vertical duct and years of grease along the duct floor, on vertical risers, attenuators and multi-storey ducts.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

The process
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes from a few hours to more than one visit, depending on duct length and access. A quick note on how to find the site and where to park makes a visit to Chilswell run smoothly.
- First the duct route is traced and every access point noted.
- Grease readings are taken at set points along the duct.
- 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.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or send details by email.
Advice
What affects the quote in Chilswell
We don’t publish a price list, because sites vary so much. What we look at:
- Parking and loading at the site
- Whether several sites go on one quote
- The condition we find in the survey
- Whether we need access equipment or extra panels
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
What to send for a quote
What to send for a quote:
- Problems your staff have spotted
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
How the job changes from site to site
Multi-storey and shared buildings
Long ducts in larger buildings can mean several visits. Visits are planned around the building’s hours, out of hours where possible.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
What happens if it’s left?
A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains, and grease may start to leak from joints. Planning a trip to Chilswell ahead is easier for everyone than a rushed one.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

Keeping the system healthy
Once we have finished, these simple steps help:
- Get panels fitted where the duct couldn’t be cleaned
- Tell us if grease leaks from the ductwork
- Don’t block access panels with shelving or stock
- File each certificate and photo report in the maintenance log
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
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.
Honest limits
Some problems need a different service or another trade:
- A failed fan motor at the end of the duct (a fan repair job)
- A duct that’s too small or badly routed for the kitchen (a design issue)
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly before booking.

Chilswell questions
Can school kitchens in Chilswell be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Chilswell. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we will fit the work in.
Do you work in villages like Chilswell?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
How long does it take to clean extract ducts?
A short duct can be cleaned in a few hours, but long or complex ducts may take several visits. We plan the work around your kitchen.
Can extra access doors be added to the duct?
Yes, we install duct access panels. We place them where they help most, and we will recommend where.
How often should kitchen ducts be cleaned?
It follows the same interval as the whole extract, ranging from 3-monthly to 12-monthly. Grease thickness testing shows whether that’s often enough.
Do we have to stop cooking while the ducts are cleaned?
We clean while the kitchen is closed, so evenings, nights and weekends are all possible. Equipment and the extract are switched off while we work.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How much does ductwork cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
