Ductwork cleaning in Blackfen

How we handle ductwork cleaning in Blackfen

Every duct has its own route. A few metres to an outside wall, or a riser up through the building to a roof fan. The survey traces the route, so we know where to get in and how long it will take. Typical jobs include thick crusts of old grease along the duct and smells of old cooking grease from the ductwork, across horizontal duct runs, bends and junctions and access panels.

In a London area like Blackfen, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.

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

Questions from Blackfen

Which fire service covers Blackfen?

London Fire Brigade is the fire and rescue service for Blackfen. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Do you work overnight in Blackfen?

Yes, evening, overnight and weekend work is normal for us. The work in Blackfen can fit around your hours. Just call 0345 646 2711 or email us with your opening times and we’ll plan around them.

Which kinds of sites do you work on?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

How long will the duct clean take?

A short duct can be cleaned in a few hours, but long or complex ducts may take several visits. We plan the work around your kitchen.

Is TR19 cleaning required by law?

No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.

Is Blackfen in your area?

Yes. We work in Blackfen and the rest of Greater London, within our South East and London area. For a fixed quote, call 0345 646 2711 or use the quote form.

What if parts of the system can’t be reached?

They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.

What do you do with what you remove?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.

Ductwork cleaning in Blackfen: the local picture

The FSA’s food hygiene register shows about 144 restaurants, cafés and works canteens and about 90 takeaways within roughly a mile and a half of the centre of Blackfen. The duct above a busy canopy coats itself in grease long before anyone sees it. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Environmental health officers from Greenwich council inspect food businesses in Blackfen. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.

If you run a café or takeaway near Falconwood station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Church and community hall kitchens, near Church of the Good Shepherd or anywhere around Blackfen, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens, like those at hospitals such as Eltham Community Hospital (about 1.7 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Blackfen is about 2 miles east of Eltham, in Greater London. Every kind of commercial site in Blackfen, ductwork cleaning is something we can help with.

Staff cleaning versus specialist work

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

How we price ductwork cleaning

Sites vary more than people expect. What affects the quote:

  • Whether it’s a one-off visit or part of a schedule
  • The size of the system
  • Site rules, permits and inductions
  • Working hours and out-of-hours timing

The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Asking for a quote

To help us quote quickly, send us:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Detail shots of panels, filters and grilles
  • Where the site is and what kind of site it is
  • A few general shots of the system

For a fixed quote, call 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

Different parts, different methods

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.

Bends and transitions

A bend can hold far more grease than a straight run of the same length. It’s scraped out and degreased, and test it before and after.

How it works

The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes anything from a few hours to several visits, depending on the length of duct, and we clear up before we go. Expect the work in Blackfen to happen after your last customer leaves, not during trading.

  1. We map the duct route and check where the access panels are.
  2. We measure grease thickness at set points before cleaning.
  3. Through the access panels, thick grease is removed by hand first.
  4. Next the ducts and risers are degreased, using whatever suits the deposit.
  5. Post-clean readings and pictures go into the report, with any unreachable section listed.

Getting ready for the visit

  • Tell us where we can park and unload
  • Find the previous report, if there is one
  • Mention any sign-in, permit or induction we need

Ask for a quote

Getting a quote doesn’t take long. 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.

Related advice

Why deal with it now?

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. It’s better booked as a planned job in Blackfen than handled as an emergency.

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Why book with us

  • One contact for all your sites in London and the South East
  • CHAS, SafeContractor and ISO 9001
  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • Out-of-hours work and a 24/7 emergency line

See how cleaning jobs are priced and how to check a contractor.

Keeping the system healthy

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • File each certificate and photo report in the maintenance log
  • Leave a way through to the access panels
  • Don’t switch the extract off early
  • Have the grease measured if cooking hours go up

You will have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.

Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.

When it’s something else

An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning will not do:

  • Undersized or badly laid-out ducts
  • A worn-out fan that needs replacing
  • Ductwork that’s corroded, split or holed (that needs a ductwork contractor)

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