How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes an hour or two for most single fans. A few photos of the system help us make the most of a visit to a place like Chandler's Cross.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Before we arrive

Advice
Extract fan cleaning in Chandler's Cross, done properly
In Chandler's Cross, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. The result is photographed for your records. If you are dealing with grease escaping from the fan outlet and thick grease on the impeller and casing, we can help, from in-line fans, axial fans and discharge points onwards.
Work in a small place like Chandler's Cross starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What your team can do, and what needs 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 can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Why deal with it now?
Vibration from an unbalanced impeller doesn’t stay small. It can wear the bearings and lead to failure, which may leave the kitchen without extraction. A planned clean beats an emergency. It’s worth booking a check, because nobody sees inside a duct day to day.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Part by part
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
Impellers and blades
The impeller is the spinning part that moves the air, and it collects grease unevenly. That is what unbalances the fan, so it’s cleaned carefully blade by blade.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the grease filters clean and in place
- Book the fan into every full TR19 clean
- Keep the fan on whenever the range is lit
- Keep records of every fan clean
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Keep the whole system on its cleaning cycle. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.

Honest limits
Not every problem is solved by extract fan cleaning, and we’d rather say so up front. It will not put right:
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A failed motor or worn bearings (that needs a fan repair or replacement)
- Damaged fan blades

Do you need extract fan cleaning in Chandler's Cross?
Each blade collects a slightly different amount. The difference throws the impeller off balance, wearing bearings and mounts. What starts as a grease problem can become a mechanical one.
Look out for these warning signs:
- A fan coated in grease inside its housing
- An extract fan with no cleaning record
- A fan shaking on its mounts
- Less air being pulled from the kitchen
Historic houses near Chandler's Cross, such as Chenies Manor House about 3.2 miles west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
