Grease filter exchange for sites in Folkestone

How we handle grease filter exchange in Folkestone

Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. We point out any that need replacing. The work covers wall canopies, school and hospital kitchens and island canopies, and common reasons people get in touch are filter washing that keeps being missed and grease dripping from the canopy.

In a town like Folkestone, most of the kitchen extracts we’re asked about belong to restaurants, cafés, pubs, takeaways and school or care home kitchens. Each has a canopy, filters, ductwork and a fan to keep clear of grease, and each is cleaned to the same TR19® standard.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How it works

There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We arrive in Folkestone once you’ve closed and leave the site ready for the morning.

  1. First, we check the canopies and the filters in them.
  2. We note any filters that are bent, damaged or missing.
  3. Greasy filters are swapped for clean ones.
  4. We check the filters are seated and the canopy is ready to use.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Preparing for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Clear loose items from the work area
  • Find the previous report, if there is one

Ask for a quote

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Advice

Why act early in Folkestone

Changing filters on schedule costs far less disruption than a blocked extract. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. The sooner the work is done, the simpler the job for a site in Folkestone.

One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.

What you get with us

  • Survey first, then a fixed quote
  • One number for every site across the South East and London
  • Evenings, overnight and weekends, plus 24/7 emergency callout
  • Trading since 2009

Aftercare tips

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

  • Tell us if the menu or opening hours change
  • Never leave gaps in the filter bank
  • Always run the extract while cooking
  • Wipe the outside of the canopy as part of daily cleaning

We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due and we can book that in.

If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.

FAQs for Folkestone

Which fire authority looks after Folkestone?

Fire safety enforcement in Folkestone is handled by Kent Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Does being near the coast affect grease filter exchange in Folkestone?

It can. Being within about 1 mile of the sea means more corrosion on metalwork in Folkestone than inland. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.

Do you offer maintenance contracts?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

Is filter exchange enough instead of a full extract clean?

No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.

Can one contract cover all our sites?

Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.

Are you insured?

Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

Do you deal with bent or broken filters?

We check every filter at each visit. We tell you about any that are damaged since a poor fit lets grease past.

Is there a cleaning option for the filters we have?

We can. Cleaning your existing filters is an option, and others prefer a straight swap. Either way, the canopy isn’t left without filters during service.

Different parts, different methods

The plenum

Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.

Mesh filters

Grease lodges deep in the layers of a mesh filter, so a quick rinse rarely gets it clean.

Grease filter exchange in Folkestone: the local picture

At about 1 mile from the coast, Folkestone is close enough for sea air to matter. Near the sea, the fan and discharge at the top of a kitchen extract corrode faster than they would inland. The FSA’s food hygiene register includes about 48 bars, pubs and nightclubs and about 12 hotels, B&Bs and guest houses within about 1.5 miles of central Folkestone. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Folkestone falls to Kent 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.

If you look after a school kitchen, at a school such as Stella Maris Catholic Primary School or anywhere near Folkestone, the holidays are the usual time for a TR19® clean. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Royal Victoria Hospital is the nearest hospital to Folkestone, about within half a mile north-east.

In-house cleaning or a specialist?

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

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.

When to call us in Folkestone

Every fry, grill and sauté sends grease-laden vapour upwards. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.

What we are most often called out for:

  • Filters so greasy the air can barely pass
  • Filter washing that keeps being missed
  • Missing filters in the filter bank
  • A greasy plenum behind the filters

A kitchen near Folkestone Central 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

  • If the quote is a fixed price or an estimate
  • Whether a written report and pictures are included
  • Whether inaccessible sections are listed on the report
  • What insurance they carry

How to choose an extract cleaning contractor

How we price grease filter exchange

Every site gets its own quote. This is what makes a difference:

  • Travel, parking and unloading
  • Access, including roofs, risers and ceiling voids
  • The scale of the work
  • Whether several sites go on one quote

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

What we need to know

To speed up the quote, please include:

  • Wide photos of the system and the area around it
  • The times we could work without disrupting the site
  • The paperwork from the last visit, if you have it
  • The postcode and the type of business

Every quote begins with a look at the system, 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, before any work starts.
