Extract fan repair in Newnham

Extract fan repair in Newnham

Grease and fans do not mix. Deposits on the impeller throw it out of balance and the vibration wears out bearings and fixings. That is why we check the grease whenever we work on a fan and can arrange a TR19® clean of the whole system at the same time. The work covers fan housings, fan motors and kitchen extract fans, and people most often call us about a worn or slipping fan belt and a fan worn beyond sensible repair.

Somewhere as small as Newnham, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. When one fails, the cooking stops, and emergency callout is available 24/7, villages included.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What a clean will not put right

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

  • Faults in the building’s electrical supply, which need an electrician
  • Grease build-up in the rest of the extract system
  • Smells from the discharge that need odour control equipment

Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly.

Parts of the system we cover

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

What we’re called out for in Newnham

Over the years, mountings loosen and rubber mounts break down. The fan’s movement then travels into the ductwork and structure, which is where knocking and rattling often come from.

If you notice any of these, it’s worth a diagnosis:

  • A fan shaking on its mountings
  • Poor airflow at the canopy
  • A dead fan motor
  • A humming noise from the fan motor

Occasional-use kitchens, such as a hall kitchen near Church of St Vincent or elsewhere in Newnham, are where a stiff or seized fan can turn up.

Those that cook under a canopy rely on a fan that runs every hour they’re open. Environmental health officers from North Hertfordshire council inspect food businesses in Newnham.

How the visit works

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few hours for most repairs, longer for a full fan replacement. The timing of a visit to Newnham is set by you, and the travel is our side of the planning.

  1. A visit is booked, in the evening or overnight if that suits.
  2. We isolate the extract and open the fan housing.
  3. We inspect every moving part and the fixings.
  4. We explain the options and quote a fixed price.
  5. We complete the work and check the fan runs smoothly.

Before we arrive

  • Let us know when the site is closed or quiet
  • Make sure equipment near the work can be switched off and left to cool
  • Move anything stored near the system

Ask for a quote

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711 or use the quote form.

Aftercare tips

To keep the system working properly between visits:

  • Never run the extract with filters missing
  • Do not turn the fan down to hide a noise
  • Note when the fan trips or cuts out
  • Keep access to the fan controls unobstructed

Once we are done, the extract is back in service. We leave the area tidy and explain anything you need to know.

A 3, 6 or 12-monthly cleaning plan brings us back at set intervals, so the fan is looked at as part of each visit and problems are spotted sooner.

Newnham questions

Will you come out to Newnham?

Yes, we work in villages as well as towns, and Newnham is covered. Just mention lanes, gates or anything else about the site when you book.

Which environmental health team covers Newnham?

Food hygiene inspections in Newnham are carried out by North Hertfordshire council. A note of when the fan failed and when it was fixed shows the problem was dealt with.

Can we book visits on a schedule?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

Do you survey before quoting?

Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.

How long will the fan be out of action?

It depends on the fault, but most jobs take anything from an hour or two to a full visit, depending on the fault. You will know more once we have found the fault.

Can you repair a fan rather than replace it?

It depends on the fault. We diagnose first and tell you whether a repair is realistic, then give you a fixed quote.

What do you do to protect the area?

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

Does a fan repair include cleaning the ductwork?

A fan repair on its own doesn’t include the ductwork. We’ll tell you what we see and quote for a TR19 clean if it’s needed.

Multi-site and managed buildings

We work for landlords, managing agents and facilities managers as well as the people running the site. 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.

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.

Staff cleaning versus specialist work

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

Fixed quotes for extract fan repair in Newnham

Every site gets its own quote. These are the things that affect it:

  • Whether we need access equipment or extra panels
  • Where the site is and how we reach it
  • The condition of the system
  • Site requirements such as sign-in and permits

You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Helping us quote

We can often survey from photos. The most useful are:

  • Problems your staff have spotted
  • The roof, plant room or outside wall the system runs to
  • The paperwork from the last visit, if you have it
  • Photos showing the whole system and its surroundings

For a fixed quote, give us a ring on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
