How we handle extract fan cleaning in Polstead Heath
A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Typical jobs include grease escaping from the fan outlet and thick grease on the impeller and casing, on in-line fans, fan housings and centrifugal fans.
Work in a small place like Polstead Heath starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Different parts, different methods
Impellers and blades
The blades of the impeller do the work, and it collects grease unevenly. That’s what unbalances the fan, so it’s cleaned carefully blade by blade.
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. We clean them where they can be safely reached, and anything we cannot reach is recorded.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a few hours where there are several fans or heavy deposits. Seeing the system in pictures first means the trip to Polstead Heath can be planned properly.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- We remove the grease from the blades, impeller and casing.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
How to prepare
- Move anything stored near the system
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet

Polstead Heath questions
Who inspects food businesses in Polstead Heath?
Kitchens in Polstead Heath are inspected by Babergh council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you work in Polstead Heath outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Polstead Heath keeps running as normal. Tell us your opening hours when you ask for a quote.
What do you do with what you remove?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Why has my extract fan got louder?
Uneven grease on the impeller often causes it. We clean the fan and tell you if anything else, like worn bearings, is to blame.
Do you cover Polstead Heath?
Yes. Polstead Heath is part of the area we cover, as part of our area across London and the South East.
Is the fan isolated during cleaning?
With the fan isolated, the extract isn’t running. That is why fan cleans are done out of hours, and the kitchen is ready when we leave.
How long does extract fan cleaning take?
It takes a couple of hours per fan, depending on its size and the build-up. We will confirm the time when we quote.
Why deal with it now?
A fan that sounds rough in Polstead Heath is often telling you the extract needs a clean. If the fan is coated, the duct before it normally is too so a full TR19 clean may be due. If the system at a site near Polstead Heath fails, there may be nowhere nearby to move to.

Do you need extract fan cleaning in Polstead Heath?
Each blade collects a slightly different amount. Over time, that imbalance shakes the fan and puts strain on the bearings. Left too long, grease turns into wear.
Clients usually contact us after spotting one of these:
- A heavily greased fan housing
- Grease escaping from the fan outlet
- Hot, greasy smells near the fan
- An extract fan with no cleaning record
Before-and-after pictures and a TR19® certificate come with every clean around Polstead Heath.

Aftercare tips
After the visit, a few habits help the work last:
- Don’t turn the fan off mid-service
- Never cook with a filter missing
- Keep records of every fan clean
- Check the report shows the fan was cleaned
When we’ve finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Fewer grease particles reaching the fan means less build-up. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
