Grease filter exchange in Clewer

Filter exchange sits between full TR19® cleans. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. That is why the whole system still needs cleaning to TR19 at the right interval. If you are dealing with a canopy running with filters missing and a greasy plenum behind the filters, we can put it right.

Size does not change the work: a kitchen in a place like Clewer gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.

Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What we do, step by step

Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes less than an hour in most kitchens. Because the survey comes first, a visit to Clewer can usually be finished without a second trip.

  1. The filters in each canopy are measured and counted.
  2. An exchange schedule is agreed to suit your cooking.
  3. On each visit, we remove the greasy filters.
  4. Clean filters go in and we check they sit snugly.
  5. The dirty filters leave with us and the next visit is booked.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Arrange a key holder or contact on site
  • Make sure equipment near the work can be switched off and left to cool

The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Managing agents and facilities teams in Clewer

Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.

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.

Part by part

Canopy filter housings

We check that filters sit snugly in the housing at each visit, because gaps let grease through.

School, care home and staff kitchens

A longer exchange interval may suit lighter cooking. The interval is set to fit.

Clewer: your questions answered

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

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 55 schools, colleges and universities with registered kitchens within about a mile and a half of Clewer. Just call 0345 646 2711, or email photos with your term dates and we will plan around them.

Do you work at weekends in Clewer?

Yes. We work evenings, overnight and at weekends. The work in Clewer can fit around your hours. Your opening times are the first thing we ask for.

Are you accredited?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Which sectors do you work in?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

Can you look after several sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.

What happens if you can’t reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

What happens to the waste?

Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.

Is there a cleaning option for the filters we have?

Yes. Cleaning your existing filters is an option while others want an exchange. Either way, the canopy isn’t left without filters during service.

Do you need grease filter exchange in Clewer?

Repeated removal and washing takes its toll on filters. Damaged filters do not sit flush and grease passes round them.

The symptoms we’re asked about most include:

  • Grease building up behind the canopy filters
  • Damaged filters letting grease past
  • Gaps where filters have been removed
  • Filters so greasy the air can barely pass

School kitchens, at schools like St Edward's Catholic First School for example, are normally cleaned in the holidays so no lunches are lost.

What your quote should include

  • When the next visit should be, and why
  • What paperwork you get at the end
  • What hours they’ll be on site
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Our hiring checklist

In-house cleaning or a specialist?

Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Kitchen extracts in Clewer

The FSA’s food hygiene register shows about 172 cafés, restaurants and staff canteens and about 20 takeaways and sandwich shops in Clewer and the streets around it, up to about 1.5 miles out. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Environmental health officers from Windsor and Maidenhead council inspect food businesses in Clewer. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand. Clewer is covered by Royal Berkshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Healthcare kitchens, like those at hospitals such as King Edward VII Hospital (about 1 mile south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. For kitchens close to Windsor & Eton Central station, where the day often starts early and ends late, the extract can be cleaned overnight.

Why act early in Clewer

A filter exchange is a few minutes; a choked extract affects a whole service. Few maintenance jobs are as easy, and one of the easiest to let slip. In a smaller place like Clewer, a site that has to close is felt quickly.

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

Looking after it afterwards

Results last longer with the right care. We suggest:

  • Report a dripping canopy early
  • Make sure we can reach the canopy on exchange day
  • Keep filter exchange and TR19 cleaning on the same plan
  • Make sure no filter is left out

Nothing changes for your staff, except one less greasy job. Just keep the canopy clear for the next visit and tell us if service times change.

Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both keeps everything on track.
