Ductwork cleaning near Southwark

Ductwork cleaning in Southwark, done properly

Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for grease leaking from duct joints and duct runs that can’t be reached, on access panels, horizontal duct runs and bends and junctions.

Kitchens in Southwark, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.

Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

FAQs for Southwark

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

Yes. Half-terms and the summer break are the natural time for school work. There are about 93 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Southwark. Just call 0345 646 2711 or use the quote form with your term dates and we will plan around them.

Can you work in Southwark outside opening hours?

Yes, nights and weekends are routine for us. That way a site in Southwark does not have to lose a day’s trading. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.

How do you clean inside the ductwork?

We survey the route, test the grease, then open the access panels. We clean the runs and risers section by section, and test again when we are done.

How often should kitchen ducts be cleaned?

It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.

Is Southwark in your area?

Yes. Our area takes in London and the counties of South East England, Southwark included.

What paperwork do you give after a duct clean?

A photo report, with readings and before and after pictures, plus a TR19 certificate for a full system clean. The report says when the next clean is due.

Where does the waste go?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.

When it’s something else

A few issues sit outside what this work can do:

  • Duct sealed behind fixed ceilings or walls
  • Ductwork that is corroded, split or holed (that needs a ductwork contractor)
  • A damper stuck open in the duct

Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.

What the work covers

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

What affects the cost of ductwork cleaning

Every site gets its own quote. These are the things that affect it:

  • How easy every part is to reach
  • Whether it’s a one-off visit or part of a schedule
  • The size of the system
  • Parking and loading at the site

Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.

What we need to know

Before you ask for a quote, gather:

  • The roof, plant room or outside wall the system runs to
  • Any access panels or hatches you can see
  • Where the site is and what kind of site it is
  • The paperwork from the last visit, if you have it

Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

Common problems we fix in Southwark

A duct with too few access doors can’t be fully cleaned. Stretches with no way in may never have been touched, and grease there keeps thickening unseen.

Most sites get in touch after spotting one of these:

  • A rancid smell from the extract duct
  • Years of grease along the duct floor
  • Grease leaking from duct joints
  • High readings at a recent grease test

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Surrey Dispensary is the nearest hospital to Southwark, about under half a mile south-east.

Questions to ask before you book

  • Whether the figure could change on the day
  • Whether they recommend a next date
  • What insurance they carry
  • Whether the quote shows VAT

How to choose an extract cleaning contractor

Different parts, different methods

Access panels

We can fit new access panels where the duct needs them, making future cleans more complete. The survey shows where they’re needed.

Horizontal duct runs

A long flat run can’t be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.

What happens if it’s left?

A partly blocked duct slows the airflow. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. A building in Southwark may have flats or offices above and alongside, and a fault in the system can affect them too.

The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.

Ductwork cleaning around Southwark

There are about 2,326 cafés, restaurants and staff canteens and about 809 takeaways and sandwich shops in and around Southwark, up to about a mile and a half out, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Southwark is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Most London extract cleaning happens at night, after the last service.

If you run a café or takeaway near Elephant & Castle station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. If you look after a school kitchen, at a school such as Charles Dickens Primary School or anywhere near Southwark, the holidays are the usual time for a TR19® clean.

The process

Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes from a few hours to more than one visit, depending on duct length and access. Security desks and permits-to-work are routine in London, so let us know what your building in Southwark needs from us.

  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. Through the access panels, thick grease is removed by hand first.
  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.

How to prepare

  • Dig out any earlier paperwork for the system
  • Mention any locked doors, roof access or ceiling voids
  • Clear loose items from the work area

Staff cleaning versus specialist work

Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
