Kitchen extract cleaning in Colney Butts

Kitchen extract cleaning for kitchens and businesses in Colney Butts

Any kitchen we clean in Colney Butts gets exactly the same specification as everywhere else we work. The job starts with a survey and grease readings, then works through canopy, plenum, filters, ductwork, fan and discharge. You get a TR19 certificate and a photo report at the end. If you are dealing with an overdue clean flagged by an EHO or fire officer and cleaning needed before an insurance renewal or survey, we can put it right, from canopies and hoods, plenums and filters and horizontal duct runs onwards. People looking for “duct cleaning near me” in Colney Butts usually mean the kitchen extract, and that’s exactly what we do: the whole run from hood to roof, cleaned to TR19® Grease.

The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, which is why a TR19® clean in Colney Butts goes well beyond the canopy.

In a smaller place like Colney Butts, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.

Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Part by part

Ductwork and risers

Bends and changes of direction trap more grease than straight runs. We test at points like these before and after cleaning, so the report shows the difference.

Restaurant and pub kitchens

Restaurants and pubs tend to cook long hours with plenty of frying and grilling, so their cleaning interval is often 3 or 6 months under BESA guidance. We clean after close or before opening.

Between visits

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

  • File each certificate with the fire risk assessment
  • Book the next clean before the date on the report
  • Refit filters properly after cleaning
  • Keep the baffle filters clean

Any section without access is marked on the report. That’s part of an honest TR19 clean, not a failing, and we can fit access panels so it’s reached next time.

Stick to the cleaning interval on the certificate. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.

Signs you need kitchen extract cleaning in Colney Butts

Hours of cooking are the biggest factor. BESA guidance sets minimum cleaning intervals of every 3 months for 12 to 16 hours a day, 6 months for 6 to 12 hours, and 12 months for 2 to 6 hours. They are minimums: measured grease levels set the real interval.

These are the problems we see most often:

  • Rancid smells from grease in the duct
  • Fat running down the canopy edge
  • Extraction mentioned at an environmental health visit
  • A kitchen taken over without any extract records

Bursars and site managers at schools such as Watford Grammar School for Girls tend to book extract cleaning for when the kitchen is empty.

Questions to ask before you book

  • Whether the whole system is included, or only the parts that are easy to reach
  • What paperwork you get at the end
  • Whether a survey comes first
  • Whether they recommend a next date

What we do, step by step

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes one visit for most kitchens, while large or complex systems may need more than one. Tell us about any gates, ladders or locked plant areas at your site near Colney Butts when you book.

  1. We start with a survey, so we know every part of the system before we quote.
  2. Set points are tested for grease thickness and the quote is fixed before work begins.
  3. With the kitchen closed and equipment off and cool, the area is sheeted.
  4. Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
  5. Readings and photos are taken again, and you receive a TR19 certificate and photo report.

Getting ready for the visit

  • Let us know about parking and loading
  • Allow time for equipment near the work to be turned off and cool down
  • Let us know about permits to work or site inductions

Common questions in Colney Butts

Can you work in Colney Butts outside opening hours?

Yes, out-of-hours work is a big part of what we do. It means the site in Colney Butts keeps running as normal. Your opening times are the first thing we ask for.

Who would carry out a food hygiene inspection at a kitchen in Colney Butts?

Kitchens in Colney Butts are inspected by Watford 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.

What do I get after the clean?

A TR19 certificate and a photo report. Certificates are issued through the BESCA Vent Hygiene Elite portal, and the report shows before and after photos, readings, any areas not reached and the next clean date.

What do you do with what you remove?

It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.

Is TR19 a legal requirement?

Strictly, the legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, not from TR19. In practice, TR19 is how kitchens show they’re managing grease, and an insurer may refuse or reduce a claim without it.

Can you quote from photos?

In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.

Do you clean the whole extract system or just the canopy?

A TR19 Grease clean covers the full extract route, not just the canopy. That means canopy, plenum, filters, ducts, risers, fan and discharge, reached through access panels where needed.

Why act early in Colney Butts

Grease build-up causes everyday problems too. Filters block, airflow drops and the kitchen gets hotter and smokier and the fan strains to keep up. Smells, dripping grease and condensation often follow. Light use slows the build-up but does not stop it.

Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

When it’s something else

A few issues sit outside what this work can do:

  • Damaged duct sections that need replacing
  • Fire dampers that will not close (that needs damper testing and remedials)
  • A fan motor that has burnt out

If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think before you book.

Parts of the system we cover

  • Horizontal duct runs
  • Extract fans
  • Vertical risers
  • Canopies and hoods
  • Discharge points
  • Plenums and filters

What affects the quote in Colney Butts

The diagnosis comes before the price. The main factors are:

  • The size of the system
  • Working hours and out-of-hours timing
  • Where the site is and how we reach it
  • How many systems or sites are involved

The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.

What to send for a quote

Photos let us diagnose from a distance. Try to include:

  • Where the site is and what kind of site it is
  • The paperwork from the last visit, if you have it
  • Your opening hours and when the area is out of use
  • Any access panels or hatches you can see

Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
