Extract fan cleaning in Clayhall
Cleaning removes grease, not wear. If we find worn bearings, a struggling motor or damage to the impeller, we will tell you and fan repair or replacement is something we also do. You get an honest view of the fan’s condition. Common call-outs are for a noisy fan that has got louder over time and a fan coated in grease inside its housing, across discharge points, axial fans and roof-mounted fans.
Kitchens around a place like Clayhall are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Grease, kitchens and Clayhall
Clayhall is within about 1 mile of the coast. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. There are about 64 restaurants, cafés and works canteens and about 24 sandwich bars and takeaways within roughly a mile and a half of the centre of Clayhall, according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. The fire and rescue service for Clayhall is Hampshire and Isle of Wight 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.
Where a hall near St Francis, or anywhere in Clayhall, hosts lunch clubs or events, its extract gathers grease just as a café’s does. A hospital like Gosport War Memorial Hospital, about 1 mile north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Clayhall is about 2 miles south-east of Gosport, in Hampshire. From the centre of Clayhall to the outskirts, we cover extract fan cleaning for every kind of premises, from a single unit to a large public building. Clayhall is one of 683 places in Hampshire we cover for extract fan cleaning.

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. Reaching it takes a specialist with the right equipment.
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, which is where we come in.
What we do, step by step
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Tell us about any gates, ladders or locked plant areas at your site near Clayhall when you book.
- We find the fan and check how it’s reached and how it’s isolated.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- We degrease the fan and housing, taking care around the motor.
- The fan is put back into service, checked and photographed.
Before we arrive
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
How to get a quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Related advice
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Don’t turn the fan off mid-service
- Note any drop in extraction at the canopy
- Look for grease stains near the discharge
- Report rattles or humming early
Where the fan needs repair rather than cleaning, the report says so. We also repair and replace extract fans, so you have one point of contact.
Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.
Signs you need extract fan cleaning in Clayhall
A fan on a roof or hidden in a ceiling void is easy to forget. A fan that has never been cleaned can be heavily coated, and the report will show it.
Any of these means the system needs a check-up:
- Grease around the motor and its mounts
- A fan coated in grease inside its housing
- A fan that has never been cleaned
- A fan that hums, whines or rumbles
If you look after a school kitchen, at a school such as Haselworth Primary School or anywhere near Clayhall, the holidays are the usual time for a TR19® clean.

Managing agents and facilities teams in Clayhall
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.

Common questions in Clayhall
Does being near the coast affect extract fan cleaning in Clayhall?
It can. Being within about 1 mile of the sea means more corrosion on metalwork in Clayhall than inland. Corroded fixings and housings are noted on the report so they can be dealt with.
Who would carry out a food hygiene inspection at a kitchen in Clayhall?
The local authority for Clayhall is Gosport council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Is the fan isolated during cleaning?
It has to be off and isolated, for safety. We clean out of hours, in the evening, overnight or at weekends, so cooking is not affected.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Can the fan be cleaned between full cleans?
Yes, we do. The report will make clear that only the fan was cleaned, so your TR19 records stay accurate. The whole system still needs cleaning at the intervals in BESA guidance.
Leave it or put it right?
A fan that sounds rough in Clayhall is often telling you the extract needs a clean. If the fan is coated, the duct before it usually is too so a full TR19 clean may be due. Around Clayhall, a kitchen or building out of action is missed right away.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
