Ventilation duct cleaning in Blackfen, done properly

We cover Blackfen and the rest of Greater London for ventilation duct cleaning, in offices, schools, healthcare buildings and retail. Every job begins with a survey and a fixed quote. Common call-outs are for toilet and washroom extracts full of fluff and dirty diffusers dropping dust into rooms, across hospitals and care homes, toilet extract systems and offices and schools.

London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Blackfen, as elsewhere, cleaning starts with an inspection of what’s there.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What staff can safely do

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

What we do, step by step

Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a day or less for a small system and a series of visits for a large one. Security desks and permits-to-work are routine in London, so let us know what your building in Blackfen needs from us.

  1. First we check the layout and any past paperwork.
  2. We inspect the ducts at chosen points to see where cleaning is needed.
  3. We cover the area below and turn off the system.
  4. Ducts, grilles and diffusers are cleaned and the debris taken away.
  5. We report on the work, listing any inaccessible sections and the next inspection date.

Before we arrive

  • Mention any sign-in, permit or induction we need
  • Dig out any earlier paperwork for the system
  • Arrange a key holder or contact on site

Ask for 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, and then send you a fixed quote. To get going, call us on 0345 646 2711, or send details by email.

Related advice

Looking after it afterwards

No system stays clean for ever, but care slows the build-up. Our tips:

  • Stick to the filter change schedule
  • Keep grilles and diffusers dusted
  • Keep the TR19 certificate and photo report in the maintenance log
  • Flag any dust coming out of the vents

Share the report with whoever looks after the building’s maintenance, so it’s all in one place. Year on year, it shows how fast dust builds up.

Keep filters changed on time. Overdue or badly fitted filters let dust into the supply ducts.

Blackfen questions

Can you work in Blackfen outside opening hours?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Blackfen needn’t be disturbed. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.

Do you clean school ventilation in Blackfen in the holidays?

Yes. The holidays are the usual time for school work. There are about 36 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Blackfen. Booking early in the term gives the best choice of holiday dates.

Are grilles and diffusers included?

Yes. Where they can be removed, they’re taken down, cleaned and refitted. Fixed ones are cleaned in place.

Does the law say we must follow TR19?

No. TR19® itself isn’t law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.

What happens if you can’t reach some of it?

The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.

What do you do with what you remove?

It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.

Are you insured?

Yes. Full insurance covers our work, and we have been trading since 2009.

Do you have a 24/7 line?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Different parts, different methods

Grilles and diffusers

Where they come out, grilles are taken down and cleaned, then put back.

Hospitals and care homes

In care settings, keeping dust contained is a priority. We protect the work area and take everything away.

The FSA’s food hygiene register lists about 36 schools, colleges and universities and about 54 care, childcare and hospital premises with registered kitchens or food service within about 1.5 miles of central Blackfen. Busy, occupied buildings like these are where clean supply air matters most. Ventilation cleaning in London buildings is usually planned for evenings or weekends. Blackfen’s nearest hospital, Eltham Community Hospital, is about 1.7 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

What affects the quote in Blackfen

You will get a fixed price before we start. It takes into account:

  • The size of the system
  • When the work can happen, such as evenings, overnight or weekends
  • Site rules, permits and inductions
  • A single visit or a regular plan

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Helping us quote

There’s no need for technical detail. It helps if you can send:

  • The roof, plant room or outside wall the system runs to
  • The paperwork from the last visit, if you have it
  • Detail shots of panels, filters and grilles
  • Photos showing the whole system and its surroundings

Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Landlords, agents and facilities managers

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
