Extract fan repair in Stevenage

How the job changes from site to site

Direct-drive fans

In a direct-drive fan, the impeller sits on the motor shaft. With no belts to wear, we look at the motor, bearings and impeller.

Roof and wall-mounted fans

Fans outside are exposed to rain and condensation. Rust on fixings and housings is a frequent find.

How we handle extract fan repair in Stevenage

Extract fan repair starts with a diagnosis. A noisy fan might need cleaning, new bearings or a new belt, while a fan that won’t start may have a motor or control fault. We explain the problem, and what it will take, before any work starts. The work covers fan housings, kitchen extract fans and roof and wall fans, and the jobs we see most are an old fan that needs replacing and a dead fan motor.

In a place the size of Stevenage, kitchens of every size depend on their extract fan to keep cooking. When a fan fails, the kitchen typically has to stop cooking, which is why our emergency callout runs 24/7.

Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What affects the cost of extract fan repair

Your quote is based on your site. We consider:

  • The scale of the work
  • Whether several sites go on one quote
  • Any permits to work or inductions
  • The times the site is available

A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.

What to send for a quote

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

  • Any symptoms, from odd noises to smells or leaks
  • Where the site is and what kind of site it is
  • A few general shots of the system
  • The times we could work without disrupting the site

Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.

For landlords and multi-site operators

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 are happy to quote for all of it.

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

Keeping the system healthy

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

  • Keep a record of any trips or stoppages
  • Save our number for the 24/7 emergency line
  • Tell us about a new rattle or whine straight away
  • Make sure the isolator and controls are easy to reach

Keep an ear on the fan after the repair. A new noise or vibration is worth reporting early, so it can be looked at before it grows.

A slipping belt or a loose mount is a small job. Ignored, they can lead to bigger failures, so it’s worth acting early.

Extract fans in Stevenage

Food Standards Agency records list about 105 restaurants, cafés and canteens and about 71 takeaways within about 1.5 miles of central Stevenage. For any of them with a canopy, the extract fan is what keeps the kitchen usable. At about 29 miles from central London, Stevenage sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Food hygiene inspections in Stevenage are the job of Stevenage council’s environmental health team. A kitchen with no working extract can fall short of the suitable and sufficient ventilation food hygiene rules expect. A kitchen without a working fan has a problem to fix quickly.

A fan that rarely runs, like one in a hall kitchen near St Hugh & St John or elsewhere in Stevenage, can seize between uses.

Do you need extract fan repair in Stevenage?

In Stevenage, as anywhere, long cooking days mean long hours for the fan. On belt-driven fans, belts stretch, crack and start to slip and a slipping belt means slower fan speed and weaker extraction.

These are the problems we see most often:

  • A worn or slipping fan belt
  • A fan running too slowly to clear the kitchen
  • An extract fan that has stopped working
  • A fan worn beyond sensible repair

School kitchens cannot easily serve lunch without extraction, so if you look after one at a school like Saint Vincent de Paul Catholic Primary School, fix a failing fan before term starts.

Before booking anyone

  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • How they set the interval to the next visit
  • When they can work, and whether that is outside your opening hours
  • Whether the figure could change on the day

Your questions about extract fan repair in Stevenage

Who do I call if an extract fan fails in Stevenage?

Extract fan emergencies in Stevenage are covered around the clock. Call 0345 646 2711 and tell us what the fan is doing, or not doing. Tell us where the fan is and how to reach it.

Do you work overnight in Stevenage?

Yes. We work evenings, overnight and at weekends. That way a site in Stevenage does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.

Is repair an option before replacing the whole fan?

That depends on what we find. We diagnose first and tell you whether a repair is realistic, then send you a fixed quote.

What makes a kitchen extract fan rattle or whine?

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

Do you have insurance?

Yes. Full insurance covers our work, and we have been trading since 2009.

Will you tell us when the next visit is due?

Yes. How often depends on use and condition, and we explain the reasoning on the report.

Which kinds of sites do you work on?

Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

How long does an extract fan repair take?

That depends on what’s wrong, but as a guide it takes a few hours for most repairs, longer for a full fan replacement. You will know more once we’ve found the fault.

What your team can do, and what needs us

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

What happens on the day

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few hours on site, depending on the fault and the access to the fan. Access to the roof, the plant room and a parking space are worth sorting out before a visit in Stevenage.

  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. A fixed quote for the repair or replacement follows.
  5. We fix the fault and run the fan to check it.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us about site rules, permits or sign-in
  • Tell us the best time to work, such as after service or at a weekend

How to get a quote

To get a fixed quote, call us on 0345 646 2711 or drop us a line 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 will typically have a quote within one working day.
