Grease filter exchange in Hunsdonbury

Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away, so the canopy is never left without filters. Common call-outs are for grease filters clogged with grease and grease collecting in the filter channels, on baffle filters, island canopies and wall canopies.

For a kitchen in or near Hunsdonbury, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When it’s something else

Grease filter exchange can’t fix everything, and we’ll tell you before work begins. It doesn’t solve:

  • Greasy ducts and risers that a filter change will not reach
  • Grease behind the filters that a swap cannot remove
  • Cooking smells reaching neighbours, which need odour control

If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.

What the work covers

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

Why it’s worth doing now in Hunsdonbury

Leaving filters too long pushes more grease into the plenum and ducts. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. It’s simpler to plan the work at Hunsdonbury now than to arrange it in a hurry later.

Every site is different, 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.

Why choose Duct Doctor in Hunsdonbury

  • We diagnose before we treat
  • Fixed quotes from a survey or pictures

Grease filter exchange around Hunsdonbury

Food Standards Agency records include about 4 pubs and bars within about 1.5 miles of central Hunsdonbury. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In Hunsdonbury, food businesses are inspected by environmental health officers from East Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Hunsdonbury sits within the area of Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Princess Alexandra Hospital is the nearest hospital to Hunsdonbury, about 2.5 miles south-east. Bursars and site managers at schools such as Hunsdon Junior Mixed and Infant School tend to book extract cleaning for when the kitchen is empty.

For landlords and multi-site operators

We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Questions from Hunsdonbury

Is Hunsdonbury within the area you cover?

Yes. Hunsdonbury is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.

Which council inspects kitchens in Hunsdonbury?

Kitchens in Hunsdonbury are inspected by East Hertfordshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

How much does a filter exchange service cost?

Pricing depends on the kitchen, so we need to know the filters and interval first. You get a fixed price before the service starts.

Do you survey before quoting?

Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.

What’s TR19?

TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Does the report say when we need you again?

Yes. Every report includes a recommended date for the next visit, based on use and what we found.

What happens to the waste?

We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.

What if some of our filters are damaged?

A bent filter leaves a gap for grease. We flag any we find and explain what’s needed.

What we do, step by step

When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes less than an hour in most kitchens. A quick note on how to find the site and where to park makes a visit to Hunsdonbury run smoothly.

  1. The filters in each canopy are measured and counted.
  2. We set the interval with you.
  3. On each visit, we remove the greasy filters.
  4. Clean filters go in and we check they sit snugly.
  5. We take the greasy set away and confirm the next date.

How to prepare

  • Clear loose items from the work area
  • Plan for cooking equipment or plant to be off before we arrive

Fixed quotes for grease filter exchange in Hunsdonbury

You’ll get a fixed price before work begins. It takes into account:

  • When the work can happen, such as evenings, overnight or weekends
  • What state the system is in
  • Where the site is and how we reach it
  • Whether it’s a one-off visit or part of a schedule

The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before we start.

Helping us quote

What to send for a quote:

  • Wide pictures of the system and the area around it
  • Close-ups of filters, grilles, hatches or access panels
  • Your last certificate, test record or report
  • 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 photos and any previous report or certificate. Once you have those, call 0345 646 2711 or email us.

When to call us in Hunsdonbury

What a kitchen cooks affects how fast filters clog. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.

If you notice any of these, it’s worth a diagnosis:

  • Staff short of time to wash filters
  • Drips falling from the filters onto equipment
  • Damaged filters letting grease past
  • Grease collecting in the filter channels

If you run a church or community hall kitchen, near St Francis Chapel or elsewhere in Hunsdonbury, its extract still collects grease from every lunch and event.

What your quote should include

  • Whether a written report and photos are included
  • What’s included in the scope, part by part
  • Whether they recommend a next date
  • Which accreditations they hold, and whether you can check them

Choosing a duct cleaning contractor

What staff can safely do

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
