Different parts, different methods

Fan housings and motors

We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease around the motor can make it run hotter, so the surrounding area is cleaned carefully.

Roof-mounted fans

Roof fans also discharge grease onto the roof around them and we check the area around the outlet. Heavy staining is noted on the report.

Extract fan cleaning in Chelmsford, done properly

A clean fan isn’t a repaired fan. If we find worn bearings, a struggling motor or damage to the impeller, we will tell you, and we also repair and replace extract fans. You’ll know whether the fan just needed cleaning or something more. Typical jobs include less air being pulled from the kitchen and a fan that hums, whines or rumbles, on in-line fans, fan housings and centrifugal fans.

In a place the size of Chelmsford, the kitchens with extract systems range from takeaways and restaurants to hotel, school and workplace kitchens. Each cooks for a different number of hours a day, so each needs cleaning at its own interval.

A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

When to call us in Chelmsford

Grease builds up unevenly on the blades. The difference throws the impeller off balance, wearing bearings and mounts. Left too long, grease turns into wear.

Most sites get in touch when they notice something like this:

  • A smell of hot grease from the extract
  • A heavily greased fan housing
  • A noisy fan that has got louder over time
  • A fan motor running hot under a coat of grease

For schools such as Trinity Road Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Questions to ask before you book

  • Proof of insurance
  • Whether the quote shows VAT
  • Exactly which parts of the system are covered
  • Which accreditations they hold, and whether you can check them

Our hiring checklist

Managing agents and facilities teams in Chelmsford

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

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

Why it’s worth doing now in Chelmsford

A fan that sounds rough in Chelmsford is often telling you the extract needs a clean. If the fan is coated, the duct before it normally is too, so it’s worth checking the whole system. Larger sites in Chelmsford are easier to manage on a planned schedule.

What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.

What you get with us

  • A single point of contact for sites across the South East and London
  • We’re fully insured
  • A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

What’s the cleaning interval for an extract fan?

It depends on how many hours the kitchen cooks in BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.

Will I get photos of the cleaned fan?

A photo report, including the fan’s condition and the next clean date. Keep it with your maintenance log.

Can you fix a fan that is worn out?

A fan that needs repair is noted on the report, with what we found. We offer extract fan repair and replacement, and if it fails outright, our 24/7 emergency line is there.

Do you work with multi-site operators?

Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.

How do you protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.

Grease, kitchens and Chelmsford

Food Standards Agency records include about 52 pubs and bars and about 4 hotels and guest houses in Chelmsford and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. It’s Chelmsford council that sends environmental health officers to food businesses in Chelmsford. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Chelmsford is covered by Essex County Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Commuter trade near Chelmsford station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Where a hall near Church of the Holy Trinity, or anywhere in Chelmsford, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Aftercare tips

Here’s the after-treatment advice, short and simple:

  • Check filters are seated before cooking
  • Listen for new noises or vibration from the fan
  • Report grease escaping from the fan
  • Flag smoke lingering at the canopy

The area around the fan is left clean, with waste grease removed. Wherever the fan is, the area around it is cleaned down.

Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.

The process

Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes a few hours where there are several fans or heavy deposits, and the area is cleaned down before we leave. We will ask where we can park in Chelmsford and how to get equipment to the system, as those shape the visit.

  1. First we check the fan’s condition and how it sounds.
  2. Once isolated, we open the fan up.
  3. Each blade is cleaned so the impeller runs evenly.
  4. Housing, outlet and the area around the motor are cleaned.
  5. The fan goes back into service with a report on its condition.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Plan for cooking equipment or plant to be off before we arrive
  • Have your last certificate or report to hand
