Ductwork cleaning in The Flints, done properly

Not sure when the ductwork was last cleaned? A few details about the system are a good start when you call 0345 646 2711 or send us an email, and we will give you a fixed quote for ductwork cleaning, typically within one working day. If you have duct runs with no cleaning record and an insurer asking for TR19 evidence, we can help, from attenuators, vertical risers and access panels onwards.

For a kitchen in or near The Flints, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.

We are 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, and we have been trading since 2009.

Fixed quotes for ductwork cleaning in The Flints

The survey tells us what the work involves. The main factors are:

  • Where the site is and how we reach it
  • One-off work versus a regular cycle
  • The times the site is available
  • How big the system is

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

Helping us quote

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • Your last certificate, test record or report
  • Detail shots of panels, filters and grilles
  • The site address and the type of premises
  • Your opening hours and when the area is out of use

For ductwork cleaning in The Flints, call 0345 646 2711 or email us. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote normally follows within one working day.

Grease, kitchens and The Flints

The FSA’s data shows about 4 pubs, bars and clubs registered across The Flints and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in The Flints falls to 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. In The Flints, food businesses are inspected by environmental health officers from North Hertfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.

A hall kitchen that only cooks for events, whether near Church of St Mary Magdalene or elsewhere in The Flints, still needs its extract cleaned, just less often. Healthcare kitchens, like those at hospitals such as Keech Hospice Care (about 3.7 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.

The Flints is about 4 miles south-west of Hitchin, in Hertfordshire.

How the visit works

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a few hours for a short run, longer for long runs and tall risers. If you can send photos, we can arrive in The Flints knowing what to expect.

  1. First the duct route is traced and every access point noted.
  2. We measure grease thickness at set points before cleaning.
  3. Access panels are opened and heavy deposits scraped out by hand.
  4. The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
  5. We test again, take photos and note any part that couldn’t be reached.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Tell us the best time to work, such as after service or at a weekend
  • Have your last certificate or report to hand

Getting a quote

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

Common problems we fix in The Flints

Grease filters that don’t seal let fat straight through. More grease reaches the ductwork than it should and it fills faster.

Signs it’s time to call us include:

  • An insurer asking for TR19 evidence
  • A duct nobody has opened in years
  • Grease leaking from duct joints
  • Thick deposits at the bottom of a vertical duct

For schools such as Offley Endowed Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

What your quote should include

  • Whether VAT is included
  • How they set the interval to the next visit
  • Whether a survey comes first
  • Which accreditations they hold, and whether you can check them

Questions to ask before booking

Aftercare tips

Once we have finished, these simple steps help:

  • Diarise the next duct clean
  • Don’t switch the extract off early
  • Consider fitting panels where the report shows gaps
  • Keep access panels clear of stored items

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.

Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.

When it’s something else

It’s worth knowing the limits before booking:

  • A worn-out fan that needs replacing
  • Faulty fire dampers
  • Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)

Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly before you book.

What the work covers

  • Access panels
  • Attenuators
  • Horizontal duct runs
  • Bends and junctions
  • Vertical risers
  • Multi-storey ducts

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, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Day-to-day cleaning is something your team can do: 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.

Common questions in The Flints

Who would carry out a food hygiene inspection at a kitchen in The Flints?

In The Flints, it’s North Hertfordshire council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Which fire authority looks after The Flints?

Hertfordshire Fire and Rescue Service is the fire and rescue service for The Flints. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

What happens if there aren’t enough access panels?

Without a way in, a section can’t be cleaned properly. We record those sections on the report and can fit access panels.

How is kitchen extract ductwork cleaned?

We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.

Do you have a 24/7 line?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.

Do you have insurance?

Yes. We’re fully insured, and the details are available on request.

Can you quote from pictures?

Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.

Why act early in The Flints

A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains, and grease may start to leak from joints. If the system at a site near The Flints fails, there may be nowhere nearby to move to.

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
