Why deal with it now?

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

Ductwork cleaning for kitchens and businesses in Grendon Underwood

Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that is where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. We’re often asked to deal with an insurer asking for TR19 evidence and a duct nobody has opened in years, across vertical risers, horizontal duct runs and multi-storey ducts.

For a kitchen in or near Grendon Underwood, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

When to call us in Grendon Underwood

Ducts in Grendon Underwood gather grease for the same reasons as ducts anywhere: daily cooking hours, the menu and the state of the filters. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.

Common reasons sites call us include:

  • A duct clean needed for an insurer
  • Readings above 200 microns from a grease thickness test
  • Grease leaking from duct joints
  • Duct runs with no cleaning record

Church and community hall kitchens, near Church of St Leonard or anywhere around Grendon Underwood, are easy to forget, but their extracts collect grease like any other.

Choosing a duct cleaning contractor

Grendon Underwood questions

Which fire service covers Grendon Underwood?

It’s Buckinghamshire Fire and Rescue Service, which covers Grendon Underwood. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Can a school canteen extract in Grendon Underwood be done out of term time?

Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Grendon Underwood, it pays to plan holiday dates ahead. Just call us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.

Can you look after several sites?

Yes. One number covers all your sites in our area, with visits on a regular schedule.

Are you accredited?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Will I get a report after the ducts are cleaned?

When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.

When is the ductwork cleaned?

Out of hours, at a time that suits the kitchen. Larger systems may be cleaned over several nights, with the kitchen ready to cook each morning.

How much notice should we give?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

What’s TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.

Keeping the system healthy

A little care between visits keeps the system in better shape. We recommend:

  • Make sure filters are seated properly
  • Keep access panels clear of stored items
  • Tell us if grease leaks from the ductwork
  • Have the grease measured if cooking hours go up

Any section of duct we couldn’t reach is listed on the report, with the reason. We can fit access panels so those sections are cleaned next time.

Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.

Staff cleaning versus specialist work

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.

When something else is needed

We’d rather tell you now than book work that won’t help, so these are the things it will not cover:

  • Parts of the duct with no way in
  • A worn-out fan that needs replacing
  • Leaking duct joints that need repair

If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think before you book.

What the work covers

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

The process

Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes from a few hours to more than one visit, depending on duct length and access, and we clear up before we go. Somewhere like Grendon Underwood, lanes, gates and parking are worth mentioning in advance.

  1. We map the duct route and check where the access panels are.
  2. Grease readings are taken at set points along the duct.
  3. We open the panels and scrape out the heaviest grease.
  4. The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
  5. Readings and pictures are repeated and any section we couldn’t reach is recorded.

Getting ready for the visit

  • Move anything stored near the system
  • Mention any sign-in, permit or induction we need
  • Tell us where we can park and unload
