Ductwork cleaning near Sutton

Ductwork cleaning in Sutton

No two duct runs are the same, in Sutton or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route and finds every access point before we quote. Typical jobs include grease pooling at the foot of the riser and stale grease odours from the duct, across vertical risers, attenuators and bends and junctions.

London kitchens tend to trade late and open early, so extract cleaning in Sutton is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.

Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How the visit works

A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. On site, the work takes from a few hours to more than one visit, depending on duct length and access. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Sutton.

  1. We start by working out how the duct runs and where it can be opened.
  2. Set points along the runs are tested for grease.
  3. Access panels are opened and heavy deposits scraped out by hand.
  4. Horizontal runs and risers are then degreased by the method that suits the deposit.
  5. Readings and pictures are repeated and any section we couldn’t reach is recorded.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Clear the space around the work
  • Tell us the best time to work, such as after service or at a weekend

What ductwork cleaning looks like in Sutton

Food Standards Agency records list about 194 restaurants, cafés and canteens and about 110 takeaways within about 1.5 miles of central Sutton. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. The fire and rescue service for Sutton is London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.

If you look after a school kitchen, at a school such as Robin Hood Junior School or anywhere near Sutton, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as St Helier Hospital (about 1.1 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands. A kitchen near Sutton (London) station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Aftercare tips

To keep the system working properly between visits:

  • Ask us about extra access panels where sections can’t be reached
  • Tell us if grease leaks from the ductwork
  • Leave a way through to the access panels
  • Keep grease filters clean and fitted whenever you cook

The report names every part of the duct that couldn’t be reached, with the reason. You can then decide whether to have access panels fitted.

Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.

What your team can do, and what needs us

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.

Multi-site and managed buildings

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Questions from Sutton

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

Food hygiene inspections in Sutton are carried out by Sutton council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.

Which fire service covers Sutton?

Sutton is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.

What’s the cleaning interval for extract ductwork?

BESA guidance sets minimum intervals by daily cooking hours: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Measured grease sets the real interval.

Do we have to stop cooking while the ducts are cleaned?

We clean while the kitchen is closed, evenings, overnight or at weekends. Equipment and the extract are switched off while we work.

What’s involved in cleaning extract ducts?

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.

How far ahead should we book?

Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.

How do you protect the area?

We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

How much does ductwork cleaning cost in Sutton?

It depends on the site, so we quote each one individually. To get one, call us on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.

How the job changes from site to site

Multi-storey and shared buildings

In a shared building, the duct links the kitchen to other spaces, which makes keeping it clean all the more important. Your certificate and report give building managers the record they need.

Attenuators and discharge

Attenuators, where fitted, quieten the extract, but they can hold grease in their linings. They’re cleaned where possible and recorded if not.

Leave it or put it right?

Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Putting off the clean only pushes readings higher. For a site in Sutton, fitting the work in overnight now is far easier than closing at short notice later.

What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

What ductwork cleaning cannot fix

To be straight with you, there are a few things this work won’t fix:

  • Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
  • A failed fan motor at the end of the duct (a fan repair job)
  • Ductwork that was poorly designed
