Extract fan cleaning for kitchens and businesses in Letchworth Garden City
Grease on a fan is not spread evenly. Heavier deposits on some blades throw the impeller off balance, leading to vibration, noise and strain on the motor and bearings. A thorough clean removes the cause. If you have thick grease on the impeller and casing and weak extraction at the canopy, we can help.
For a pub, café or restaurant in a town like Letchworth Garden City, losing a day’s trade to cleaning is not an option, so cleans are booked after closing, early in the morning or on a quiet day. The kitchen is handed back clean and ready to cook.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

When something else is needed
Extract fan cleaning cannot fix everything, and we’ll tell you before work begins. It will not put right:
- A dirty duct upstream of the fan
- A fan that’s too small for the system (a design question)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.
What the work covers

What the work involves, part by part
Kitchens with long cooking hours
In a busy kitchen, the fan rarely gets a rest, which means grease and wear add up quickly. Cleaning on time helps keep it running.
Fan housings and motors
Some fans use a belt drive. Belts and pulleys are checked and cleaned where safe for your records.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
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.
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes an hour or two for one fan, longer when it’s hard to reach. A few photos of the system and its access points help us plan a visit in Letchworth Garden City.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Getting ready for the visit
- Clear the space around the work
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Look for grease stains near the discharge
- Notice when the fan starts to sound different
- Keep each photo report with the maintenance log
- Keep access to the fan clear
Keep the report with the maintenance log and fire risk assessment. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
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.

Why act early in Letchworth Garden City
Vibration from an unbalanced impeller doesn’t stay small. It can wear the bearings and lead to failure and a kitchen can’t cook safely without extraction. Cleaning it early is far less disruptive. Nothing in a duct, damper or fan improves by being left.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
