Grease filter exchange near Harefield

About our grease filter exchange in Harefield

Each visit is quick and tidy. The greasy filters come out, clean ones go in and make sure there are no gaps between them. Anything that needs attention is pointed out. If you’re dealing with grease left in baffles after washing and weak extraction at the canopy, we can put it right, from baffle filters, school and hospital kitchens and restaurants and pubs onwards.

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

We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Different parts, different methods

School, care home and staff kitchens

Lighter kitchens can often go longer between changes. We agree the schedule to match.

Busy restaurant and pub kitchens

In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.

What happens on the day

We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes less than an hour in most kitchens. Because the survey comes first, a visit to Harefield can usually be finished without a second trip.

  1. We count and measure the filters in every canopy.
  2. A change schedule is agreed to match the kitchen’s cooking hours.
  3. Each visit starts with the used filters being removed.
  4. We fit clean filters and check they sit snugly in the housing.
  5. If a filter is damaged or the plenum needs attention, we tell you.

Preparing for the visit

  • Make sure someone can let us in and lock up afterwards
  • Mention any sign-in, permit or induction we need
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Grease, kitchens and Harefield

Harefield is within about 3 miles of the coast. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The Food Standards Agency lists about 15 pubs and bars as registered food businesses within roughly a mile and a half of the centre of Harefield. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Harefield get their food hygiene inspections from Southampton council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.

School kitchens, at schools like Harefield Primary School for example, are typically cleaned in the holidays so no lunches are lost. South Stoneham House, about 1.9 miles north-west, is one of the historic houses near Harefield; if you run event catering at a venue like that, cleans can be booked between functions.

Aftercare tips

No system stays clean for ever, but care slows the build-up. A few tips:

  • Report damaged filters so they can be replaced
  • Always run the extract while cooking
  • Tell us if the menu or opening hours change
  • Watch for grease drips between visits

If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due and we can book that in.

If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen in the ducts.

Harefield: your questions answered

Do you clean school canteen extracts around Harefield out of term?

Yes, and it’s the easiest time to do it. Around Harefield, the Food Standards Agency lists about 27 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or send us an email, and we will fit the work in.

Which fire and rescue service is responsible for Harefield?

That’s Hampshire and Isle of Wight Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

Is there a cleaning option for the filters we have?

Yes, filters can be cleaned on a schedule as well as exchanged. We’ll explain the options when we quote.

Is Harefield in your area?

Yes. We cover Harefield and across Southampton, within our South East and London area. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form.

What if some of our filters are damaged?

Filters that no longer fit properly need replacing. We will tell you which ones and why when we find them.

Can we skip TR19 cleans if the filters are changed regularly?

No. Some grease passes the filters as vapour and settles in the ducts and the whole system still needs its TR19 clean.

Can one contract cover all our sites?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.

What should go in our maintenance log?

Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. One maintenance log per site keeps it simple.

What we’re called out for in Harefield

Kitchens in Harefield, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for a filter bank to clog.

These are the problems we see most often:

  • Filters so greasy the air can barely pass
  • Damaged filters letting grease past
  • Weak extraction at the canopy
  • Grease dripping from the canopy

A hall kitchen that only cooks for events, whether near Church of St James or elsewhere in Harefield, still needs its extract cleaned, just less often.

Choosing a duct cleaning contractor

For landlords and multi-site operators

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

What affects the quote in Harefield

Sites vary more than people expect. The main factors:

  • Whether several sites go on one quote
  • One-off work versus a regular cycle
  • Site requirements such as sign-in and permits
  • Parking and loading at the site

What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.

What we need to know

There’s no need for technical detail. Just send:

  • When the site is open and when it’s quiet
  • Detail shots of panels, filters and grilles
  • Problems your staff have spotted
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.

What happens if it’s left?

A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system and few are as easy to forget. Even a site near Harefield that’s only busy part of the week needs its system checked on a schedule.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
