Ductwork cleaning across Abbots Langley

What the work involves, part by part

Horizontal duct runs

The underside of a horizontal duct collects the most grease. We scrape out the heavy layer first, then the walls and roof are cleaned too.

Vertical risers

In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. We test those as a separate job.

Ductwork cleaning for kitchens and businesses in Abbots Langley

Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. An honest report beats a guess. The work covers horizontal duct runs, bends and junctions and access panels, and common reasons people get in touch are proof of duct cleaning for the insurer and years of grease along the duct floor.

Around a smaller place like Abbots Langley, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.

For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Keeping the system healthy

A little care between visits keeps the system in better shape. Our advice:

  • Consider fitting panels where the report shows gaps
  • Keep your cleaning records together
  • Leave a way through to the access panels
  • Ask for a grease thickness test if the kitchen gets busier

Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.

The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.

What affects the cost of ductwork cleaning

You will get a fixed price before work begins. It takes into account:

  • Whether several sites go on one quote
  • The size of the system
  • The condition of the system
  • Any permits to work or inductions

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.

What we need to know

When you contact us, these details help:

  • How we’d reach plant on a roof or in a plant room
  • The times we could work without disrupting the site
  • Close-ups of filters, grilles, hatches or access panels
  • The postcode and the type of business

To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or email photos.

Why it’s worth doing now in Abbots Langley

A dirty duct is something insurers ask about. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. A certificate that covers the ductwork is what they want to see. When a site near Abbots Langley shuts unexpectedly, the people who rely on it notice at once.

What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.

Abbots Langley: your questions answered

Which council inspects kitchens in Abbots Langley?

Kitchens in Abbots Langley are inspected by Three Rivers 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.

Do you cover smaller places like Abbots Langley?

Yes, we work in villages as well as towns, and Abbots Langley is covered. Photos of the system and directions to the site help us plan the visit.

Which sectors do you work in?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

How often should kitchen ducts be cleaned?

BESA guidance sets minimum intervals by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings may show it needs doing sooner.

Are you fully insured?

Yes. We carry full insurance and have been trading since 2009.

What shows that the ducts need a clean?

Drips, smells and weak extraction are clues, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.

Can you quote from photos?

In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.

What’s TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Grease, kitchens and Abbots Langley

Food Standards Agency data counts about 37 cafés, restaurants and staff canteens and about 21 sandwich bars and takeaways in Abbots Langley and the streets around it, up to about 1.5 miles out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Hertfordshire Fire and Rescue Service covers Abbots Langley. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In Abbots Langley, food businesses are inspected by environmental health officers from Three Rivers council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.

A hall kitchen that only cooks for events, whether near Church of St Lawrence the Martyr or elsewhere in Abbots Langley, still needs its extract cleaned, just less often. If you look after a school kitchen, at a school such as Tanners Wood Junior Mixed and Infant School or anywhere near Abbots Langley, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Leavesden Hospital (about 0.5 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

When it’s something else

We will always give you a straight diagnosis, so here’s what this work can’t put right:

  • Fire dampers that do not close (they need testing and remedials)
  • Leaking duct joints that need repair
  • A failed fan motor at the end of the duct (a fan repair job)

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