How we handle extract fan cleaning in Clothall

Not all extract fans are the same: roof-mounted units, inline fans within the duct, and wall fans. The way in depends on the type and the survey shows us how to reach it. If you’re dealing with vibration from an unbalanced impeller and a fan motor running hot under a coat of grease, we can help, from centrifugal fans, axial fans and roof-mounted fans onwards.

In a small place like Clothall, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.

For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What extract fan cleaning looks like in Clothall

The FSA’s food hygiene register shows about 3 cafés, restaurants and staff canteens in Clothall and the streets around it, up to about 1.5 miles out. 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 Clothall is Hertfordshire 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. Environmental health officers from North Hertfordshire council inspect food businesses in Clothall. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Bursars and site managers at schools such as Weston Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Clothall is Lister Hospital, about 4.1 miles south-west.

What happens on the day

Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a couple of hours per fan, depending on its size and the build-up. Seeing the system in photos first means the trip to Clothall can be planned properly.

  1. We start by checking where the fan sits and how to isolate it.
  2. With the fan isolated, the housing is opened.
  3. The impeller and the housing around it are scraped clean.
  4. Blades, housing and the area around the motor are degreased with care.
  5. It’s closed up, run and checked, and photos go into your report.

Before we arrive

  • Mention any locked doors, roof access or ceiling voids
  • Find the previous report, if there is one
  • Arrange a key holder or contact on site

How the job changes from site to site

Kitchens with long cooking hours

Long cooking hours mean more grease reaches the fan. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.

Roof-mounted fans

Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. Heavy staining is noted on the report.

Your questions about extract fan cleaning in Clothall

Can you get to a site in Clothall?

Yes, we work in villages as well as towns, and Clothall is covered. A survey first, from pictures or a visit, means we arrive with the right kit.

Which environmental health team covers Clothall?

Kitchens in Clothall are inspected by North Hertfordshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

Can we book visits on a schedule?

Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.

What paperwork do I get after a fan clean?

Every clean has a photo report, along with notes on the fan’s condition. A full clean adds a TR19 certificate from the BESCA Vent Hygiene Elite portal.

Will we have to shut during the visit?

Not usually. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.

Who has the legal duty for fire safety?

It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.

Where does the waste go?

It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.

Managing agents and facilities teams in Clothall

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.

Facilities teams in offices, schools and healthcare sites book us too in Clothall and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.

What happens if it’s left?

A greasy fan at the discharge can spread grease onto the roof or wall around it. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. Somewhere as small as Clothall, losing a kitchen or building to a fault is felt by everyone who uses it.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

When to call us in Clothall

A fan on a roof or hidden in a ceiling void is easy to forget. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.

The symptoms we’re asked about most are:

  • Burning smells from the fan area
  • A fan that has never been cleaned
  • Grease around the motor and its mounts
  • A heavily greased fan housing

Church and community hall kitchens, near Church of St Mary or anywhere around Clothall, are easy to forget, but their extracts collect grease like any other.

Questions to ask before booking

Staff cleaning versus specialist work

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

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.

Between visits

Simple habits between visits make a real difference. Our advice:

  • Never cook with a filter missing
  • Listen for new noises or vibration from the fan
  • Note any drop in extraction at the canopy
  • Check the report shows the fan was cleaned

You get before and after photos of the impeller and housing. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.

A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.
