Our kitchen extract cleaning service in AL6

Duct Doctor has been cleaning kitchen extract systems since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. The work covers plenums and filters, canopies and hoods and discharge points, and common reasons people get in touch are heavy grease build-up inside the duct runs and grease drips onto cooking equipment.

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 floors and nearby surfaces are sheeted. On site, it takes one visit for most kitchens, while large or complex systems may need more than one.

  1. You send pictures or we visit, and the system is surveyed from canopy to discharge.
  2. We take grease readings at set points and give you a fixed quote.
  3. The kitchen is closed, the equipment cooled and everything nearby protected.
  4. We work through the system from the canopy to the fan and discharge.
  5. Readings are repeated, photos taken, and your TR19 certificate and photo report issued.

How we quote

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

How to get a quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

What’s near Welwyn

Locally, jobs take us to businesses close to Stable Door pub, Danesbury Park and Monk's Walk School. Also close by are Homerswood Primary and Nursery School (1.1 miles south-east) and Parish Church of St Mary (under half a mile north). Welwyn’s nearest station is Welwyn North station, roughly 1.1 miles south-east of the centre. Nearby you’ll also find Queen Elizabeth II Hospital (3.5 miles south) and Datchworth Museum (2.7 miles north-east). Open spaces near Welwyn include Mardley Heath.

Kitchen extract cleaning around AL6

In AL6, a busy kitchen in a place such as Welwyn Garden City, Welwyn and Oaklands and a quiet village kitchen need very different cleaning intervals. The right interval comes from hours of use and grease readings.

In England, the Fire Safety Order puts the duty on the responsible person to assess and reduce fire risk, and each certificate and photo report is a record you can keep in your log book.

Welwyn: A hospital like Queen Elizabeth II Hospital, about 3.5 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If your kitchen is in a listed or historic building, like the houses around Welwyn (Digswell House is about 0.9 miles south-east), fitting access panels needs care.

Why it fails

A lot of duct grease gets there because the filters let it through. Filters that are bent, badly fitted, missing or left uncleaned let more fat into the plenum and duct, and from there it travels on to the fan.

Look out for these warning signs:

  • Heavy grease build-up inside the duct runs
  • An extract that has never been cleaned to TR19
  • Grease dripping from the canopy or filters
  • Missing paperwork after a change of operator

What kitchen extract cleaning can’t fix

An honest diagnosis matters more to us than a booking, so here’s what kitchen extract cleaning won’t do:

  • Ductwork that’s corroded, split or leaking (that is for a ductwork contractor)
  • Faulty fire dampers in the duct
  • A fan motor or bearings that have failed (that needs a fan repair or replacement)

What staff can safely do

Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

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

What happens if it’s left?

Any food business in AL6 can expect visits from the council’s environmental health officers, and they look at the cleanliness of the premises and equipment, extraction included. Keeping the extract clean helps the whole kitchen pass muster.

What your quote should include

  • What records you’ll receive afterwards
  • What hours they’ll be on site
  • What insurance they carry
  • Whether the quote shows VAT

What affects the cost of kitchen extract cleaning

Before we fix a price, we need to know a few things. We check:

  • The scale of the work
  • Access, including roofs, risers and ceiling voids
  • When the work can happen, such as evenings, overnight or weekends
  • What state the system is in

Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Helping us quote

You don’t need the technical terms. It helps if you can send:

  • Any access panels or hatches you can see
  • A few general shots of the system
  • The roof, plant room or outside wall the system runs to
  • The postcode and the type of business

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

AL6: your questions answered

How do you keep the site clean during the work?

Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

What about areas you can’t get to?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

How far ahead should we book?

That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

Will I get a certificate after the clean?

Every clean comes with a TR19 certificate and a photo report. They belong in the maintenance log, ready for your insurer or an inspection.

Which parts of the extract do you clean?

Every part the air passes through, as far as access allows. Where there are not enough access panels to reach a section, it’s recorded, and we can fit new ones.

What information do you need?

Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
