Extract fan cleaning in Preston
Any fan serving a kitchen in Preston is cleaned the same careful way as anywhere else: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. If you’re dealing with a heavily greased fan housing and grease around the motor and its mounts, we can put it right, from centrifugal fans, in-line fans and discharge points onwards.
Size doesn’t change the work: a kitchen in a place like Preston gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Do you need extract fan cleaning in Preston?
The cooler the air, the more grease drops out, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.
Common reasons sites call us are:
- A fan that no longer moves enough air
- Grease stains around the discharge
- Hot, greasy smells near the fan
- Thick grease on the impeller and casing
School kitchens, at schools like The Abbey School for example, are typically cleaned in the holidays so no lunches are lost.

Fixed quotes for extract fan cleaning in Preston
Before we fix a price, we need to know a few things. We check:
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- How easy every part is to reach
- Parking and loading at the site
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes a couple of hours per fan, depending on its size and the build-up. Because the survey comes first, a visit to Preston can typically be finished without a second trip.
- 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.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need

Your questions about extract fan cleaning in Preston
Will you come out to Preston?
Yes, Preston is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can a school canteen extract in Preston be done out of term time?
Yes, out-of-term visits are normal for schools. With about 8 schools and colleges on the FSA’s register within roughly a mile and a half of Preston, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Why is my extract fan noisy?
An unbalanced impeller, usually from uneven grease, is a common cause. After cleaning, we’ll tell you if wear or damage is also involved.
How often does the fan need cleaning?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: every 3, 6 or 12 months. Some fans need attention sooner.
Can you clean the fan on its own?
Yes, where it makes sense. We’ll often suggest checking the duct too, as a greasy fan normally means a greasy duct, but the choice is yours.
How long is a fan clean?
That depends on the fan’s size, its position and how much grease there is. Typically it takes an hour or two for one fan, longer when it’s hard to reach.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.

What a clean will not put right
Not every problem is solved by extract fan cleaning, and we will tell you before we start. It won’t put right:
- An impeller that is bent or split
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
If in doubt, call 0345 646 2711 or email us and we will say what we think before booking.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What extract fan cleaning looks like in Preston
At about 3 miles from the coast, Preston is close enough for sea air to matter. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. The Food Standards Agency lists about 22 bars, pubs and nightclubs and about 3 hotels and guest houses as registered food businesses in and around Preston, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Preston falls to Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Volunteers running a hall kitchen near St Catherine's Church, or anywhere in Preston, may not know when the extract was last cleaned, and a grease test settles it. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Belmont House and Gardens is about 3.3 miles south-west), access may need planning.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Report rattles or humming early
- Book the fan into every full TR19 clean
- Don’t turn the fan off mid-service
- Keep access to the fan clear
The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.
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.
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.
Inline duct fans
Inline fans can be in tight spaces, so the method is planned in advance. Anything out of reach is recorded.
