Extract fan cleaning for sites in North Watford

Keeping the system healthy

So the system stays in good health:

  • Report grease escaping from the fan
  • Make sure the fan is included each time
  • Note any drop in extraction at the canopy
  • Notice when the fan starts to sound different

When we have finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.

Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.

About our extract fan cleaning in North Watford

Is the extract fan louder than it used to be, or the airflow weaker? A few details or a photo help when you phone us on 0345 646 2711 or drop us a line, and you’ll get a fixed price, typically within one working day. The work covers axial fans, fan housings and roof-mounted fans, and people most often call us about grease escaping from the fan outlet and a fan that no longer moves enough air.

Size doesn’t change the work: a kitchen in a place like North Watford gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we are called out for in North Watford

The cooler the air, the more grease drops out, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.

Common reasons sites call us are:

  • Burning smells from the fan area
  • Grease escaping from the fan outlet
  • An extract fan with no cleaning record
  • A fan that no longer moves enough air

A kitchen near Watford North station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Questions to ask before you book

Different parts, different methods

Fan housings and motors

The housing around the impeller catches grease flung off the blades. We clean it along with the blades.

Inline duct fans

Some fans are built into the duct itself. They’re reached through access panels or by opening the casing after isolating them.

North Watford kitchens: local notes

Food Standards Agency data counts about 158 restaurants, cafés and canteens and about 50 sandwich bars and takeaways within roughly a mile and a half of the centre of North Watford. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Fire safety in North Watford falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Watford council inspect food businesses in North Watford. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.

Volunteers running a hall kitchen near St Peter's Church, or anywhere in North Watford, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to North Watford is Watford General Hospital, about 1.8 miles south.

Why act early in North Watford

Vibration from an unbalanced impeller does not stay small. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. Cleaning it early is far less disruptive. Booking ahead lets us plan the trip to North Watford at a time that suits you.

The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before work begins, so you know where you stand.

What your team can do, and what needs us

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

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’re happy to quote for all of it.

Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

How it works

Each visit runs to the same pattern: protect the area, make the system safe, do the work, clear away and hand over the paperwork. The visit itself takes an hour or two for one fan, longer when it’s hard to reach. We plan the journey to North Watford and bring what the job is likely to need.

  1. The fan is found and its type, access and isolation checked.
  2. We isolate the power before opening the housing.
  3. We scrape the heavy grease from the blades and housing.
  4. Blades, housing and surrounds are degreased with care around the electrics.
  5. It’s closed up, run, checked and photographed for the report.

Before we arrive

  • Agree a time when the area can be out of use
  • Allow time for equipment near the work to be turned off and cool down
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Ask for a quote

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

North Watford: your questions answered

Do you work overnight in North Watford?

Yes, we can come after you close and finish before you open. The work in North Watford can fit around your hours. Your opening times are the first thing we ask for.

Will you come out to North Watford?

Yes. Villages and rural sites across the South East are part of our work, North Watford included. A survey first, from pictures or a visit, means we arrive with the right kit.

Do you survey before quoting?

Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.

How do you protect the area?

We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

Do we lose a day’s trading?

Typically not. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.

What happens to the waste?

We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.

Do you offer emergency callouts?

Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.

What information do you need?
