How we handle TR19 inspection in Dartford

BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. The work covers wet film thickness tests, access surveys and deposit thickness tests, and people most often call us about pre-clean surveys before a first TR19 clean and confirming a clean reached the whole system.

Kitchens in towns like Dartford are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Sections we cannot reach are listed on the report, and access panels can be added.

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

Honest limits

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

  • Fire safety duties beyond the extract system
  • Ductwork that was designed or installed badly
  • Heavy deposits found on test, which still need cleaning

Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly before booking.

What we work on in Dartford

  • Insurer audits
  • Pre-clean surveys
  • Wet film thickness tests
  • Deposit thickness tests
  • Access surveys
  • Post-clean checks

What happens if it’s left?

A check after cleaning shows whether the work reached every part it should have, while there’s still time to put anything right. Whatever the system, dirt and wear only get worse.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

Why choose Duct Doctor in Dartford

  • Work around your opening hours, with 24/7 emergency cover
  • A written report with pictures after each visit
  • CHAS and SafeContractor accredited, with ISO 9001
  • Fixed quotes from a survey or pictures

Read what affects the cost and how to check a contractor.

Between visits

Results last longer with the right care. Here’s what we suggest:

  • Keep canopy edges and gutters wiped down
  • Book the next test on the date in the report
  • Look out for grease drips round the canopy edge
  • Keep access panels clear and unpainted

For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.

Keep certificates, reports and readings in one place so you can produce them quickly.

What the work involves, part by part

Canopy and plenum

Clean-looking filters don’t mean a clean plenum. So we measure behind the filters, not just in front.

Restaurants, pubs and hotels

Inspections are done when the kitchen is closed or quiet so the kitchen keeps cooking.

How it works

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes an hour or two for a single kitchen, longer for a large or complex system, and we clear up before we go. Three things shape a visit in Dartford: when you’re closed, where we can park and how we get to the system.

  1. We agree a time when the kitchen is closed or quiet.
  2. The system is checked from canopy to discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. Each test point and any access problems are photographed.
  5. We send a report setting out the readings, pictures and next steps.

Getting ready for the visit

  • Name a contact who can let us in at the agreed time
  • Make sure equipment near the work can be switched off and left to cool
  • Mention any parking or loading restrictions

Getting a quote

There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or email us.

Advice

Kitchen extracts in Dartford

The FSA’s data shows about 35 pubs and bars and about 5 hotels, B&Bs and guest houses registered within 1.5 miles or so of the middle of Dartford. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In Dartford, food businesses are inspected by environmental health officers from Dartford council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Dartford is Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Bursars and site managers at schools such as Dartford Primary Academy tend to book extract cleaning for when the kitchen is empty. Volunteers running a hall kitchen near Church of the Holy Trinity, or anywhere in Dartford, may not know when the extract was last cleaned, and a grease test settles it.

What we are called out for in Dartford

Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.

Signs it’s time to call us include:

  • Post-clean verification after another contractor’s clean
  • Kitchens whose menu or hours have changed
  • Systems cleaned on a calendar with no measurements
  • Sections of duct that can’t be reached

Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Dartford is West Hill Hospital, about 0.6 miles west.

What to look for in a quote

  • If they look at the system before pricing
  • Whether the whole system is included, or only the parts that are easy to reach
  • What happens if part of the system cannot be accessed
  • What records you’ll receive afterwards

Questions to ask before you book

For landlords and multi-site operators

For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Questions from Dartford

Can you clean school kitchen extracts in Dartford during the holidays?

Yes. The holidays are the usual time for school work. Food Standards Agency records list about 17 schools, colleges and universities with registered kitchens within about a mile and a half of Dartford. Booking early in the term gives the best choice of holiday dates.

Which fire service covers Dartford?

Fire safety enforcement in Dartford is handled by Kent Fire and Rescue Service. 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 you verify a clean after it’s been done?

A post-clean check records grease readings and pictures after the work, for our cleans and other firms’ alike.

What’s TR19?

A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.

Can we book visits on a schedule?

How long does a TR19 inspection take?

Expect it to take a couple of hours for a typical kitchen extract system. We fit it around when the kitchen is closed or quiet.
