About our extract fan repair in Chelmsford

Working on a fan in Chelmsford means switching the extract off first, so we plan it around your service. Evenings, overnight and weekends are all possible, and a fan that dies mid-service can go straight to our 24/7 line. The work covers kitchen extract fans, roof and wall fans and fan motors, and people most often call us about poor airflow at the canopy and vibration spreading from the fan into the ducts.

In Chelmsford, extract fans serve kitchens, washrooms and plant rooms in buildings of every size. Spotting the signs early means a planned repair rather than an emergency.

The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Fixed quotes for extract fan repair in Chelmsford

The quote reflects the site in front of us. We consider:

  • Whether several sites go on one quote
  • Parking and loading at the site
  • Site requirements such as sign-in and permits
  • One-off work versus a regular cycle

Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

What to send for a quote

To help us quote quickly, please include:

  • The roof, plant room or outside wall the system runs to
  • Where the site is and what kind of site it is
  • Your opening hours and when the area is out of use
  • Close-ups of filters, grilles, hatches or access panels

Need a price for extract fan repair? Please give us a ring on 0345 646 2711 or drop us a line and tell us about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.

Between visits

To keep the system working properly between visits:

  • Clean or change filters on schedule
  • Make sure the isolator and controls are easy to reach
  • Don’t wait for a noisy fan to stop
  • Never run the extract with filters missing

Listen to the fan over the next few weeks. A new noise or vibration is worth reporting early, so it can be looked at before it grows.

Clogged filters make the fan strain. Changing or cleaning them on time takes load off the motor and protects the motor.

Common problems we fix in Chelmsford

Bearings wear out with heat and long hours. Worn bearings whine, rumble or grind and a seized bearing stops the fan.

These are the problems we see most often:

  • A squealing belt on start-up
  • Poor airflow at the canopy
  • Vibration spreading from the fan into the ducts
  • A fan that keeps cutting out

If you manage a school such as Trinity Road Primary School and the kitchen fan is getting louder, the next break is the time to deal with it.

Choosing a duct cleaning contractor

What extract fan repair cannot fix

In fairness, there are a few things this work will not fix:

  • Problems with the gas supply or its interlock valve
  • Smells from the discharge that need odour control equipment
  • A system that needs redesigning rather than repairing

If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think.

What the work covers

  • Roof and wall fans
  • Fan motors
  • Bearings
  • Belts and pulleys
  • Kitchen extract fans
  • Fan housings

What happens on the day

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes a few hours for most repairs, longer for a full fan replacement. We’ll ask where we can park in Chelmsford and how to get equipment to the system, as those shape the visit.

  1. We ask what the fan is doing, from noise and vibration to a full stop.
  2. Power to the fan is isolated before we open the housing.
  3. We check the motor, bearings, drive, impeller and mountings.
  4. We explain the fault and give you a fixed price for the fix.
  5. The repair or replacement is carried out and the fan is run and checked.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Mention any sign-in, permit or induction we need
  • Tell us where we can park and unload

Why deal with it now?

In kitchens with an interlocked gas supply, no extract can mean no cooking. Without extraction, the heat and fumes build up fast, so a failing fan is worth dealing with early. The longer a system in Chelmsford goes without attention, the more there is to clean or fix.

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 work begins.

How the job changes from site to site

Impellers and housings

Where an impeller is bent or corroded, cleaning won’t help. It may need replacing, or the fan may need replacing as a whole.

Roof and wall-mounted fans

Noise from an outside fan can carry beyond the kitchen. Loose fixings and worn mounts are often the cause.

Chelmsford: your questions answered

Do you work at weekends in Chelmsford?

Yes. We work evenings, overnight and at weekends. It means the site in Chelmsford keeps running as normal. Let us know the hours you are closed and we’ll book within them.

Who inspects food businesses in Chelmsford?

Kitchens in Chelmsford are inspected by Chelmsford council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.

What paperwork should we keep on file?

Every certificate and report from each visit, filed in the maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.

What happens if you can’t reach some of it?

Anything we can’t reach goes on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.

Does a faulty extract fan always need replacing?

That depends on what we find. After diagnosing, we explain whether it can be repaired and quote a fixed price for the option you choose.

Will you fit a new fan if ours cannot be repaired?

Yes. Replacing a fan is part of our fits and repairs work, and we will explain the options.

How much notice should we give?

Earlier is better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
