What the work involves, part by part
Fan housings and motors
Inside the casing, grease is thrown onto the walls. It’s scraped and degreased with the impeller.
Kitchens with long cooking hours
A long-hours kitchen cannot afford a fan failure. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
About our extract fan cleaning in Deptford
A fan never collects grease in a neat, even layer. Uneven build-up unbalances the impeller, leading to vibration, noise and strain on the motor and bearings. Cleaning the impeller and housing puts that right. If you’re dealing with burning smells from the fan area and grease around the motor and its mounts, we can help, from axial fans, in-line fans and discharge points onwards.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Deptford, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
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’re fully insured.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes an hour or two for one fan, longer when it’s hard to reach. Night and weekend working is normal for us in London, and a site in Deptford is no exception.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading

FAQs for Deptford
Which fire authority looks after Deptford?
Fire safety enforcement in Deptford is handled by London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you come to Deptford after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What’s the cleaning interval for an extract fan?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Grease readings and the fan’s condition can show it needs more.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Can you fix a fan that’s worn out?
Cleaning removes grease, but it cannot fix worn parts. We repair and replace extract fans as well, with a fixed quote first.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

When to call us in Deptford
A greasy fan in Deptford is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
Common reasons sites call us include:
- A fan coated in grease inside its housing
- A smell of hot grease from the extract
- A fan that has never been cleaned
- A motor area thick with grease
A hospital like Miller General Hospital, about within half a mile south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before you book
- What’s included in the scope, part by part

- If the quote is a fixed price or an estimate
- Whether VAT is included
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Check the report shows the fan was cleaned
- Listen for new noises or vibration from the fan

If the fan needs more than a clean, we will say so plainly. Fan repair and replacement are services we offer too, so you have one point of contact.
Keep the route to the fan clear. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
