Extract fan cleaning in Fratton
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. Common call-outs are for weak extraction at the canopy and grease stains around the discharge, across discharge points, axial fans and centrifugal fans.
For a smaller kitchen near Fratton, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Duct Doctor has been trading since 2009, and we’re 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.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
What happens if it’s left?
A fan that sounds rough in Fratton is often telling you the extract needs a clean. Grease on the fan means grease in the duct before it, so it’s worth checking the whole system. Booking now means the visit to Fratton is planned around you, not forced by a breakdown.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

What happens on the day
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. The visit takes a couple of hours per fan, depending on its size and the build-up. In a smaller place like Fratton, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- 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
- Mention any parking or loading restrictions
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive

Fratton questions
Does the sea air around Fratton make a difference to extract fan cleaning?
It can. Salt air reaches Fratton, which is within about 2 miles of the coast, and it speeds up rust. A fan housing that is rusting near the coast can fail sooner, so it’s worth catching early.
Who enforces fire safety at workplaces in Fratton?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Fratton. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Is it safe to clean the fan while the kitchen is open?
It has to be off and isolated, for safety. Cleans are done when the kitchen is closed, so cooking isn’t affected.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
How long will it take to clean the fan?
A single accessible fan doesn’t take long, but hard-to-reach fans take more time. We plan it out of hours.
Does a TR19 kitchen extract clean cover the fan?
Yes. A TR19 Grease clean covers everything from canopy to discharge, and the fan sits right in that path, so it’s cleaned too.
What we’re called out for in Fratton
A greasy fan in Fratton is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire, and a hot, struggling motor doesn’t help.
It’s time to book a visit if you see:
- Burning smells from the fan area
- A fan coated in grease inside its housing
- Grease around the motor and its mounts
- Weak extraction at the canopy
Where a hall near St Mary's Church, or anywhere in Fratton, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- Proof of accreditation you can verify
- When they can work, and whether that is outside your opening hours
- Whether the quote is based on a survey or pictures
- Whether the figure could change on the day
Grease, kitchens and Fratton
Sea air reaches Fratton, which sits within about 2 miles of the coast. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. According to Food Standards Agency records, there are about 97 pubs and bars and about 21 hotels and guest houses in Fratton and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fratton sits within the area of Hampshire and Isle of Wight 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.
If you look after a school kitchen, at a school such as Penhale Infant School & Nursery or anywhere near Fratton, the holidays are the usual time for a TR19® clean. Commuter trade near Fratton station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A cracked or broken impeller (it needs replacing)
- A dirty duct upstream of the fan

What we work on in Fratton
- Fan housings
- Roof-mounted fans
- Discharge points
- In-line fans
- Centrifugal fans
- Axial fans
Looking after it afterwards
So the system stays in good health:
- Report grease escaping from the fan
- Check filters are seated before cooking
- Check the report shows the fan was cleaned
- Listen for new noises or vibration from the fan
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.
