Grease filter exchange across Green Street Green

Grease filter exchange in Green Street Green: the local picture

Food Standards Agency records list about 10 restaurants, cafés and canteens and about 8 sandwich bars and takeaways across Green Street Green and its immediate surroundings (about a mile and a half). Clogged filters slow the airflow, and busy kitchens like these clog them fast. It’s Dartford council that sends environmental health officers to food businesses in Green Street Green. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Green Street Green is covered by Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.

Healthcare kitchens, like those at hospitals such as Darent Valley Hospital (about 1.7 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

How we handle grease filter exchange in Green Street Green

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 baffle filters, school and hospital kitchens and restaurants and pubs, and the jobs we see most are hand-washed filters that still look greasy and filters left unwashed on busy weeks.

Somewhere as small as Green Street Green, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.

The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Different parts, different methods

Canopy filter housings

Every exchange includes a check of how the filters sit, because gaps let grease through.

Mesh filters

Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks, so they need changing often.

Signs you need grease filter exchange in Green Street Green

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

These are the problems we see most often:

  • Hand-washed filters that still look greasy
  • Gaps where filters have been removed
  • Poor airflow through the filters
  • Filters that leave gaps in the canopy

Term dates shape school work: for a school like Greenlands Primary School, an extract clean fits neatly into a half-term or summer break.

Questions to ask before booking

What grease filter exchange cannot fix

We will not sell you work that does not address the problem, so these are the things it won’t cover:

  • A fan that is failing or too weak for the system
  • Grease behind the filters that a swap can’t remove
  • Grease deep in the extract system

Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before you book.

What the work covers

  • Restaurants and pubs
  • Island canopies
  • Wall canopies
  • Mesh filters
  • School and hospital kitchens
  • Baffle filters

What affects the quote in Green Street Green

You will get a fixed price before any work starts. It takes into account:

  • Whether it’s a one-off visit or part of a schedule
  • The condition of the system
  • The scale of the work
  • The number of sites or systems

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

What to send for a quote

Many jobs can be priced from pictures and some basics. Useful things to send:

  • Wide photos of the system and the area around it
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Your last certificate, test record or report
  • Any access panels or hatches you can see

To help us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711, or send details by email.

Why act early in Green Street Green

Changing filters on schedule costs far less disruption than a blocked extract. Few maintenance jobs are as easy, and one of the easiest to let slip. Rural sites can’t always move to another kitchen or room when something fails.

What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before we start.

Why us?

  • A single point of contact for sites across the South East and London
  • Trading since 2009
  • Fixed quotes, normally within one working day
  • CHAS and SafeContractor accredited, with ISO 9001

Green Street Green questions

Can you work in Green Street Green outside opening hours?

Yes, we can come after you close and finish before you open. That way a site in Green Street Green doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.

Can a school canteen extract in Green Street Green be done out of term time?

Yes, holiday work suits schools best. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Green Street Green. Just phone us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.

Is Green Street Green in your area?

Yes. We cover Green Street Green and across Kent, as part of our work across South East England and London. For a fixed quote, ring 0345 646 2711 or use the quote form.

What types of premises do you cover?

Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

Is there a survey before the work?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.

Does a filter exchange replace TR19 cleaning?

No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system, with a certificate and photo report.

Are you accredited?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.

Are you insured?

Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.

The process

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes anything from a few minutes to an hour or so, depending on the number of filters. In a small place like Green Street Green, the journey is planned ahead and the visit arranged around the site’s hours.

  1. We look at the canopies and the condition of the filters.
  2. We note any filters that are bent, damaged or missing.
  3. We exchange the dirty filters for a clean set.
  4. The filters are checked for fit before we go.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Before we arrive

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Mention any parking or loading restrictions
  • Name a contact who can let us in at the agreed time

Getting a quote

Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Advice

Keeping the system healthy

Aftercare is simple, and it helps at the next visit:

  • Mention it if the kitchen gets busier
  • Watch for grease drips between visits
  • Don’t refit a filter that is bent
  • Wipe the outside of the canopy as part of daily cleaning

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.

Filter exchange and TR19 cleaning work best together. Setting both up on a schedule means neither slips.
