About our grease filter exchange in Crosswater

A clean set of filters is a simple, regular dose of prevention. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. Full TR19 cleaning still comes at the right interval, with a certificate. The work covers wall canopies, baffle filters and school and hospital kitchens, and common reasons people get in touch are bent or damaged filters that don’t sit properly and grease collecting in the filter channels.

In a small place like Crosswater, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.

We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

Between visits

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

  • Do not let the full clean slip because filters are changed
  • Look out for drips from the canopy
  • Keep the canopy clear for exchange visits
  • Tell us if the menu or opening hours change

The canopy looks cleaner and the air moves better from the moment they’re fitted. Keep the extract running while you cook so they catch grease as intended.

Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.

What grease filter exchange looks like in Crosswater

About 38 miles out from central London, Crosswater is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Kitchens in Crosswater get their food hygiene inspections from Waverley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.

If you look after a school kitchen, at a school such as St John's CofE Aided Infant School or anywhere near Crosswater, the holidays are the usual time for a TR19® clean. Volunteers running a hall kitchen near St John the Evangelist, or anywhere in Crosswater, may not know when the extract was last cleaned, and a grease test settles it.

Crosswater is about 4 miles south of Farnham, in Surrey. Crosswater gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos.

When to call us in Crosswater

Kitchens in Crosswater, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for a filter bank to clog.

Clients typically contact us after spotting one of these:

  • Filters that leave gaps in the canopy
  • Grease left in baffles after washing
  • A greasy plenum behind the filters
  • Filters so greasy the air can barely pass

Historic houses near Crosswater, such as Farnham Castle about 4.9 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Questions to ask before booking

  • Whether a written report and pictures are included
  • Proof of insurance
  • When the next visit should be, and why
  • Whether the whole system is included, or only the parts that are easy to reach

Our hiring checklist

How the visit works

On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. A quick note on how to find the site and where to park makes a visit to Crosswater run smoothly.

  1. The filters in each canopy are measured and counted.
  2. We set the interval with you.
  3. The dirty set is lifted out.
  4. A clean set is fitted and checked for gaps.
  5. We take the greasy set away and confirm the next date.

How to prepare

  • Have your last certificate or report to hand
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Allow time for equipment near the work to be turned off and cool down

Get a fixed quote

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

What a clean won’t put right

Before you book, it helps to know what’s not included:

  • A canopy that needs a proper clean
  • A canopy that does not capture the vapour properly
  • Grease deep in the extract system

If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we’ll give you a straight answer.

What we work on in Crosswater

  • Baffle filters
  • Restaurants and pubs
  • Wall canopies

What your team can do, and what needs us

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Questions from Crosswater

Who inspects food businesses in Crosswater?

That is Waverley council, whose environmental health officers carry out food hygiene inspections in Crosswater. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

Do you cover smaller places like Crosswater?

Yes, Crosswater is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.

Can we book visits on a schedule?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

What is TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Will I get paperwork for my records?

Yes. Each visit ends with a written report and pictures, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.

Where does the waste go?

It leaves the site with us when we go. During the work, it’s contained to keep the area clean.

Do you work with multi-site operators?

Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.

How far ahead should we book?

Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.

Fixed quotes for grease filter exchange in Crosswater

There’s no set price list, because no two systems are the same. The quote depends on:

  • Site requirements such as sign-in and permits
  • One-off work versus a regular cycle
  • The scale of the work
  • Whether we need access equipment or extra panels

No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Helping us quote

A few details help us quote accurately. With your enquiry, please include:

  • Any previous report or certificate
  • A few general shots of the system
  • Where the site is and what kind of site it is
  • The roof, plant room or outside wall the system runs to

Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then ring 0345 646 2711 or use the quote form.
