Extract fan cleaning in Warren Street
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. We are often asked to deal with rough running from the extract fan and grease around the motor and its mounts, across discharge points, in-line fans and fan housings.
Work in a small place like Warren Street 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.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What extract fan cleaning looks like in Warren Street
Warren Street sits within the area of Kent 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. About 41 miles out from central London, Warren Street is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Term dates shape school work: for a school like The Lenham School, an extract clean fits neatly into a half-term or summer break.

Part by part
Impellers and blades
The blades of the impeller do the work, and grease builds up on them unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.
Fan housings and motors
The housing around the impeller catches grease flung off the blades. It’s scraped and degreased with the impeller.
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Run the extract throughout cooking
- Flag smoke lingering at the canopy
- File the fan’s report with your other records
- Keep access to the fan clear
Once it’s clean, the fan is closed up and run to check it’s working smoothly. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
What happens if it’s left?
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. A planned visit to Warren Street is easier to arrange than an emergency callout.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

FAQs for Warren Street
Do you work in villages like Warren Street?

Who would carry out a food hygiene inspection at a kitchen in Warren Street?
That’s Maidstone council, whose environmental health officers carry out food hygiene inspections in Warren Street. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Do you repair extract fans as well as clean them?
Fan repair and replacement is part of what we do. If we find wear or damage, we’ll explain it and send you a fixed quote.
How long will it take to clean the fan?
One easily reached fan is quick, while fans on high roofs or in tight voids take longer. It’s done while the kitchen is closed.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call us on 0345 646 2711, or email photos.
Common problems we fix in Warren Street
The fan sits at the end of the grease’s journey. Whatever grease is still in it settles on the impeller and inside the housing where the spinning blades spread it around.
Keep an eye out for any of the following:
- Grease stains around the discharge
- A motor area thick with grease
- An extract fan that vibrates or rattles
- Thick grease on the impeller and casing
Belmont House and Gardens, about 4.1 miles north-east, is one of the historic houses near Warren Street; if you run event catering at a venue like that, cleans can be booked between functions.
What to look for in a quote
- If the quote is a fixed price or an estimate
- What happens if part of the system can’t be accessed
- Whether the quote is based on a survey or photos
- Whether a written report and pictures are included
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes an hour or two for one fan, longer when it’s hard to reach. A few pictures of the system help us make the most of a visit to a place like Warren Street.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it cannot run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- We reassemble, run and photograph the fan.
Before we arrive
- Arrange a key holder or contact on site
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive

Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
