Ventilation duct cleaning in Bellingham

What staff can safely do

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Ventilation duct cleaning in Bellingham, done properly

We cover Bellingham and the rest of Greater London for ventilation duct cleaning, from offices and schools to hospitals, care homes and shops. Every job begins with a survey and a fixed quote. The work covers grilles and diffusers, general extract ductwork and toilet extract systems, and people most often call us about supply ducts with years of dust inside and toilet and washroom extracts full of fluff.

Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Bellingham.

Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Honest limits

To be straight with you, some problems need a different fix:

  • Leaking or broken duct sections
  • Leaks from roofs, pipes or walls into the ductwork
  • Cooking extract ducts, which are a separate specialist clean

If you are not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.

What we work on in Bellingham

  • Grilles and diffusers
  • Offices and schools
  • Hospitals and care homes
  • Toilet extract systems
  • Supply ductwork
  • General extract ductwork

Between visits

How long the results last depends on use and care. Here’s what we suggest:

  • Watch for water stains around grilles
  • Flag any dust coming out of the vents
  • Don’t run the ventilation while builders are sanding or cutting
  • Do not block grilles with furniture or storage

If there’s building work planned, protect the ventilation. Turn off the system or cover the openings during dusty jobs.

Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.

What happens if it’s left?

Clean ducts let the air move as designed, which takes strain off the fans. Leaving them means the plant works harder for the same result. Leaving it on a busy London site only adds to the work.

Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

The process

The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a shift or two for a small system, longer for a whole building, and the area is cleaned down before we leave. We fit London jobs around the building rather than the other way round, so a visit in Bellingham is usually out of hours.

  1. We agree timings that suit the building, including evenings and weekends.
  2. Access panels are opened along each run.
  3. We photograph the ducts, then clean each section in turn.
  4. We clean the grilles and diffusers and put them back.
  5. We take after pictures and send the certificate and report.

Before we arrive

  • Let us know about permits to work or site inductions
  • Move anything stored near the system
  • Make sure someone can let us in and lock up afterwards

How we price ventilation duct cleaning

The diagnosis comes before the price. The main factors are:

  • How many systems or sites are involved
  • One-off work versus a regular cycle
  • Site requirements such as sign-in and permits
  • Where the site is and how we reach it

The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

Asking for a quote

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

  • The postcode and the type of business
  • Any symptoms, from odd noises to smells or leaks
  • The times we could work without disrupting the site
  • A few general shots of the system

If you need ventilation duct cleaning in Bellingham, call 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote usually follows within one working day.

How the job changes from site to site

Extract ductwork

Extract fans pull air through these ducts, so a blocked duct strains them. Clearing the duct helps the fan do its job.

Offices and retail

Fit-outs in offices and shops leave dust in the ventilation. A clean before handover is a sensible step.

Bellingham questions

Do you work overnight in Bellingham?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.

Do you do school ventilation cleaning in Bellingham in the summer holidays?

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 37 schools, colleges and universities with registered kitchens within about a mile and a half of Bellingham. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.

Can you look after several sites?

Yes. Send the list of sites and the work at each and you’ll get one fixed quote.

Does the law say we must follow TR19?

No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.

How does TR19 Air differ from TR19 Grease?

TR19® Air deals with general ventilation, while TR19® Grease deals with kitchen extract. Under TR19® Air, inspection decides when cleaning is needed.

How do you protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

Are grilles and diffusers included?

Yes, along with the ducts behind them. They show up in the photo report before and after.

Do you offer emergency callouts?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
