How we handle ductwork cleaning in Three Bridges
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for gaps where access panels were never fitted and an insurer asking for TR19 evidence, on horizontal duct runs, vertical risers and multi-storey ducts.
Kitchens around a place like Three Bridges are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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. That’s our job.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes from a few hours to more than one visit, depending on duct length and access. Everything the job in Three Bridges needs is worked out beforehand, from the survey.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Questions from Three Bridges
Which fire authority looks after Three Bridges?
It’s West Sussex Fire and Rescue Service, which covers Three Bridges. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you clean school kitchen extracts in Three Bridges during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Three Bridges. Booking early in the term gives the best choice of holiday dates.
How long does ductwork cleaning take?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. Visits are planned out of hours.
How can I tell if my extract ducts are dirty?
Signs include grease dripping from joints, smells and a fan working harder, but measuring is the reliable way to know. Grease thickness testing shows exactly where the duct stands.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What’s the cleaning interval for extract ductwork?
BESA guidance sets minimum intervals by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease sets the real interval.
Are you fully insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
What does TR19 mean?
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.
When to call us in Three Bridges
Risers carry the extract up through the building. Grease clings to the walls and can run down to the base as liquid grease runs down. Access along its height is needed to clean it properly.
Keep an eye out for these warning signs:
- Proof of duct cleaning for the insurer
- Thick deposits at the bottom of a vertical duct
- Fat dripping from the ductwork
- Smells of old cooking grease from the ductwork
If you cook for passing trade around Three Bridges station, the extract can be cleaned between your last and first customer.
Questions to ask before booking

- How they set the interval to the next visit
- Whether a survey comes first

What the work involves, part by part
Attenuators and discharge
At the end of the duct is the discharge. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Horizontal duct runs
The underside of a horizontal duct collects the most grease. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
Why deal with it now?
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. You choose the date of a planned visit, and a breakdown never asks.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.

Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Three Bridges get their food hygiene inspections from Crawley council.

Three Bridges is covered by West Sussex 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.

Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Store the certificate with the fire risk assessment
- Get panels fitted where the duct couldn’t be cleaned
- Keep the fan on while anything is cooking
- Flag drips from the duct right away
The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
