Hersden: your questions answered

Do you cover smaller places like Hersden?

Yes, Hersden is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.

Do you cover Hersden for emergency fan repairs?

Our emergency line runs 24/7, and Hersden is within the area we cover. Use 0345 646 2711, our emergency number, at any time. Details of the make and model help us plan the repair.

Which records should we keep?

Every certificate and report from each visit, filed in the maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.

Can one contract cover all our sites?

Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.

What’s TR19?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

What happens if you cannot reach some of it?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

What do you do to protect the area?

With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.

Do you survey before quoting?

Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.

Extract fan repair in Hersden, done properly

Grease is hard on extract fans. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. So when we repair extract fan, we look at the grease too and can arrange a TR19® clean of the whole system at the same time. The work covers fan housings, belts and pulleys and roof and wall fans, and people most often call us about a belt-driven fan that squeals and weak extraction and a smoky kitchen.

Around a place like Hersden, a pub, café or care home kitchen with a failed fan cannot carry on cooking as normal. Our 24/7 emergency line is there for exactly that.

We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How it works

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 we take it from there. Before we leave, the area is tidied and the paperwork follows. For a site near Hersden, the work is booked around your opening hours, evenings and weekends included.

  1. You describe the fault and we arrange a visit.
  2. On site, the fan is safely isolated.
  3. We diagnose the fault, checking the controls as well as the fan.
  4. You get a fixed price for putting it right.
  5. We fix the fault and run the fan to check it.

Before we arrive

  • Find the previous report, if there is one
  • Name a contact who can let us in at the agreed time
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Ask for a quote

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

How we price extract fan repair

The quote reflects the site in front of us. We take into account:

  • Access, including roofs, risers and ceiling voids
  • Any permits to work or inductions
  • The condition we find in the survey
  • Where the site is and how we reach it

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

What we need to know

Photos let us diagnose from a distance. The most useful are:

  • A few general shots of the system
  • Any previous report or certificate
  • The postcode and the type of business
  • Detail shots of panels, filters and grilles

If you need extract fan repair in Hersden, ring 0345 646 2711, or send details by email. Let us know the site type and the opening hours, and send pictures or your last report if you can. We usually send a fixed quote within one working day.

Do you need extract fan repair in Hersden?

When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot, trips out or eventually burns out.

Clients typically contact us when they notice something like this:

  • A whining or grinding extract motor
  • A belt-driven fan that squeals
  • A fan running too slowly to clear the kitchen
  • An overheating extract motor

School kitchens can’t easily serve lunch without extraction, so if you look after one at a school like Hersden Village Primary School, fix a failing fan before term starts.

What to look for in a quote

  • How areas they cannot reach will be recorded
  • Which accreditations they hold, and whether you can check them

How to choose an extract cleaning contractor

How the job changes from site to site

Roof and wall-mounted fans

An external fan faces the weather as well as the grease. Rust on fixings and housings is a frequent find.

Direct-drive fans

An impeller coated in grease vibrates straight into the motor bearings. Sometimes a clean is all it needs, if the bearings haven’t been damaged.

Why it’s worth doing now in Hersden

Where the cooking gas supply is interlocked with the extract, a failed fan can stop the kitchen cooking. Even without an interlock, cooking without extraction isn’t sensible, so a failing fan is worth dealing with early. It’s easy to lose track of when the work was last done on a quieter site.

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

Why Hersden businesses choose us

  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • Fully insured
  • CHAS and SafeContractor accredited, with ISO 9001
  • One number for every site across the South East and London

Aftercare tips

Aftercare is simple, and it makes the next visit easier:

  • Keep the area around the fan controls clear
  • Get a noisy fan checked rather than slowed down
  • Write down when the fan misbehaves
  • Save our number for the 24/7 emergency line

Once we are done, the extract is back in service. We clear up after ourselves and talk you through what we found.

A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, which means the fan is seen regularly and wear is caught earlier.

Landlords, agents and facilities managers

Facilities teams in offices, schools and healthcare sites book us too across Kent. Work can be phased by floor, building or site to keep disruption down.

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
