What affects the cost of extract fan repair

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

  • Where the site is and how we reach it
  • Whether we need access equipment or extra panels
  • The number of sites or systems
  • The size of the system

What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.

Helping us quote

What to send for a quote:

  • Close-ups of filters, grilles, hatches or access panels
  • Your last certificate, test record or report
  • A few general shots of the system
  • When the site is open and when it’s quiet

We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.

Extract fan repair in Coldharbour

A faulty fan doesn’t always mean a new one. Often a clean, a new belt or new bearings brings it back, and that’s what we will recommend. Where the motor has burnt out or the unit is past saving, a replacement suited to the system goes in. The work covers fan housings, belts and pulleys and kitchen extract fans, and people most often call us about a dead fan motor and a motor that trips out or overheats.

In a small place like Coldharbour, fans are often on an outside wall or roof, open to wind and rain. That, with the grease, is hard on motors and bearings.

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, ready for your insurer.

Extract fan repair around Coldharbour

Environmental health officers from Mole Valley council inspect food businesses in Coldharbour. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That is one more reason not to keep cooking with a broken fan. Coldharbour is about 25 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.

If a fan fails in Coldharbour at night or at a weekend, our emergency line is open.

Landlords, agents and facilities managers

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.

Facilities teams in offices, schools and healthcare sites book us too in Coldharbour and across Surrey. Work can be phased by floor, building or site around the people who use them.

How it works

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes anything from an hour or two to a full visit, depending on the fault. Somewhere as small as Coldharbour, the date and timings are agreed with you well before the day.

  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. You get our diagnosis and a fixed quote to repair or replace.
  5. The repair or replacement is carried out and the fan is run and checked.

Preparing for the visit

  • Let us know when the site is closed or quiet
  • Allow time for equipment near the work to be turned off and cool down
  • Name a contact who can let us in at the agreed time

Ask for a quote

Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Part by part

Motors and bearings

The motor and its bearings work hardest. Heat, grease and long running hours all wear them.

Belt-driven fans

Squealing at start-up often points to a belt. Belts are checked for wear, tension and alignment and replaced if they’re worn.

What extract fan repair can’t fix

We’d rather tell you now than book work that won’t help, so here are the limits:

  • Ductwork designed too small for the kitchen’s cooking
  • A greasy canopy and duct that a fan repair won’t touch
  • Gas interlock faults that a Gas Safe registered engineer must deal with

If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we will give you a straight answer.

Where we work

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

What your team can do, and what needs us

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Your questions about extract fan repair in Coldharbour

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

Kitchens in Coldharbour are inspected by Mole Valley council’s environmental health officers. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.

Is there an emergency callout for extract fans in Coldharbour?

We run a 24/7 emergency line for failed extract fans, and Coldharbour is part of our area. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.

How much notice do you need?

That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

Does a faulty extract fan always need replacing?

It depends on the fault. After diagnosing, we explain whether it can be repaired, then send you a fixed quote.

Why is our extract fan so noisy?

Noise normally comes from grease build-up, bearings, belts or loose fixings. Each sounds a little different, and we diagnose it on site.

Will we have to shut during the visit?

Usually not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.

Do you replace extract fans as well as repair them?

Yes. We fit replacement fans as well as repairing old ones and we’ll talk you through what’s involved.

What types of premises do you cover?

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

What we are called out for in Coldharbour

Grease that gets past the filters ends up on the fan. It builds up on the impeller blades unevenly, and an unbalanced impeller shakes and the noise follows.

What we are most often called out for:

  • Poor airflow at the canopy
  • A belt-driven fan that squeals
  • A fan rattling in its housing
  • Vibration spreading from the fan into the ducts

A fan that rarely runs, like one in a hall kitchen near Christ Church or elsewhere in Coldharbour, can seize between uses.
