Extract fan repair for sites in Graveley

How we handle extract fan repair in Graveley

Extract fan repair starts with a diagnosis. A noisy fan might need cleaning, new bearings or a new belt; a dead fan can point to the motor or its controls. We explain the problem, and what it will take, before any work starts. Typical jobs include a belt-driven fan that squeals and a fan worn beyond sensible repair, across belts and pulleys, roof and wall fans and kitchen extract fans.

Somewhere as small as Graveley, 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.

A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why deal with it now?

A noisy fan rarely fixes itself. Bearings that are left to wear can fail suddenly, and that often happens mid-service. A repair booked now is simpler than an emergency later. Planning a trip to Graveley ahead is easier for everyone than a rushed one.

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Graveley questions

Who carries out food hygiene inspections in Graveley?

Kitchens in Graveley are inspected by North Hertfordshire council’s environmental health officers. Keeping the fan serviced is easier than explaining a broken one on inspection day.

Can you get to a site in Graveley?

Yes, Graveley is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.

Can one contract cover all our sites?

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

What if our extract fan fails during service?

We provide a 24/7 emergency callout. Cooking without working extraction isn’t sensible so we will work to get it back in service.

What will a fan repair or replacement cost?

The price depends on the diagnosis. Once we have looked at it, you get a fixed quote for the repair or the replacement.

Do you look at the system first?

Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.

How do you protect the area?

Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.

How much notice should we give?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

What we do, step by step

There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes anything from an hour or two to a full visit, depending on the fault. Rural roads and tight entrances are worth telling us about before a visit to Graveley.

  1. We ask what the fan is doing, from noise and vibration to a full stop.
  2. With the fan safely isolated, we open it up for a proper look.
  3. Each part is checked in turn: motor, bearings, drive, impeller and fixings.
  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.

Before we arrive

  • Arrange a key holder or contact on site
  • Move anything stored near the system
  • Let us know about parking and loading

Ask for a quote

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, ring 0345 646 2711 or drop us a line.

Different parts, different methods

Fan controls

We check the controls as part of every diagnosis since the motor is not always to blame.

Direct-drive fans

Direct-drive fans have the impeller mounted straight on the motor. With no belts to wear, we look at the motor, bearings and impeller.

Extract fan repair around Graveley

The FSA’s food hygiene register shows about 8 restaurants, cafés and works canteens and about 3 takeaways across Graveley and its immediate surroundings (about a mile and a half). A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. At about 31 miles from central London, Graveley sits well inside the area we cover. The visit is fixed around your opening hours, not ours. It’s North Hertfordshire council that sends environmental health officers to food businesses in Graveley. Food hygiene rules expect food premises to have suitable and sufficient ventilation. That makes a fan repair urgent rather than something to put off.

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

Signs you need extract fan repair in Graveley

Some faults are in the controls rather than the fan. A failed speed controller or a wiring fault can stop a fan so we check the controls before blaming the motor.

Signs it’s time to call us include:

  • A failed fan that needs a replacement
  • Vibration spreading from the fan into the ducts
  • A fan that won’t start at all
  • A squealing belt on start-up

Hall kitchens near Church of St Mary, or anywhere around Graveley, often use their fans only now and then, and an idle fan can stick.

Questions to ask before you book

How we price extract fan repair

The price is fixed before any work begins. It takes into account:

  • What state the system is in
  • Whether several sites go on one quote
  • The scale of the work
  • Parking and loading at the site

One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before work begins.

Asking for a quote

To speed up the quote, send us:

  • The site address and the type of premises
  • The times we could work without disrupting the site
  • Detail shots of panels, filters and grilles
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

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, the quote is fixed before any work is booked.

Landlords, agents and facilities managers

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. With shared responsibility, good records help everyone.

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
