Extract fan cleaning for kitchens and businesses in Dartford

Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. Where only the fan is cleaned, the report says so. If you’re dealing with fat spreading onto the roof or wall by the fan and less air being pulled from the kitchen, we can put it right.

Many kitchens in a town like Dartford were fitted into buildings built for something else, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.

The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Fixed quotes for extract fan cleaning in Dartford

Before we fix a price, we need to know a few things. We check:

  • Site rules, permits and inductions
  • When the work can happen, such as evenings, overnight or weekends
  • How many systems or sites are involved
  • The condition we find in the survey

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711 or email us for straight advice and a fixed quote.

Helping us quote

To speed up the quote, send us:

  • Any access panels or hatches you can see
  • The site address and the type of premises
  • The times we could work without disrupting the site
  • Photos showing the whole system and its surroundings

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Dartford questions

Can you work in Dartford outside opening hours?

Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.

Who would carry out a food hygiene inspection at a kitchen in Dartford?

That’s Dartford council, whose environmental health officers carry out food hygiene inspections in Dartford. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.

Can we book visits on a schedule?

Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.

How do you protect the area?

By covering it before any work starts. We keep the work contained and clean down when we finish.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.

Do you work in Dartford?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Dartford.

Do you repair extract fans as well as clean them?

A clean won’t mend wear. We repair and replace extract fans as well, with a fixed quote first.

What makes a kitchen extract fan vibrate?

An unbalanced impeller, usually from uneven grease, is a common cause. We clean the fan and tell you if anything else, like worn bearings, is to blame.

For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

Part by part

Impellers and blades

While the impeller is clean, we can see its condition: cracks, bent blades or wear. Anything we see goes on the report.

Fan housings and motors

We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease on and around the motor can trap heat, so we clean what we safely can.

What we do, step by step

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes an hour or two for most single fans. Let us know how to reach the roof or plant area at your site in Dartford, and where the van can go.

  1. First we check the fan’s condition and how it sounds.
  2. Once isolated, we open the fan up.
  3. The impeller is cleaned blade by blade so it runs balanced.
  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

  • Clear loose items from the work area
  • Plan for cooking equipment or plant to be off before we arrive
  • Dig out any earlier paperwork for the system

How to get a quote

For a fixed quote, call us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.

Aftercare tips

A little care between visits keeps the system in better shape. Our advice:

  • Never cook with a filter missing
  • Check the report shows the fan was cleaned
  • Don’t store items in front of the fan’s access point
  • File the fan’s report with your other records

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.

Keep the route to the fan clear. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.

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. That is our job.

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. That part needs specialist access and equipment.

Extract fan cleaning in Dartford: the local picture

Food Standards Agency data counts about 85 restaurants, cafés and works canteens and about 60 sandwich bars and takeaways in and around Dartford, up to about a mile and a half out. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Dartford sits within the area of Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Dartford, food businesses are inspected by environmental health officers from Dartford council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

Volunteers running a hall kitchen near Church of the Holy Trinity, or anywhere in Dartford, may not know when the extract was last cleaned, and a grease test settles it. School kitchens, at schools like Dartford Primary Academy for example, are normally cleaned in the holidays so no lunches are lost. If you run a café or takeaway near Dartford station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
