Ventilation duct cleaning near South Harrow

Ventilation duct cleaning in South Harrow

We cover South Harrow and the rest of Greater London for ventilation duct cleaning, in offices, schools, healthcare buildings and retail. Each building gets a survey first and a fixed quote. The work covers supply ductwork, offices and schools and grilles and diffusers, and common reasons people get in touch are dusty supply ductwork that hasn’t been cleaned in years and odours carried round the building by the ducts.

Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in South Harrow, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.

The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Inside an extract duct: heavy deposits on the left, cleaned metal on the right

Between visits

Aftercare is simple, and it helps at the next visit:

  • Store cleaning certificates where auditors can find them
  • Make sure nothing is stacked against extract grilles
  • Include grilles in the cleaning rota
  • Stick to the filter change schedule

Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.

Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.

Staff cleaning versus specialist work

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

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

How the job changes from site to site

Supply ductwork

Supply ducts carry air from the AHU into the rooms. Fine dust that gets past the filters settles along the runs, and it’s cleaned out through access panels.

Grilles and diffusers

Grilles and diffusers that are designed to come out are removed for cleaning, then put back.

What a clean will not put right

A few issues sit outside what this work can do:

  • Cooking extract ducts, which are a separate specialist clean
  • Controls and BMS faults that affect the system
  • Design problems with the ductwork layout

If you’re not sure, just call 0345 646 2711, or email photos and we will give you a straight answer.

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

How the visit works

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We fit London jobs around the building rather than the other way round, so a visit in South Harrow is typically out of hours.

  1. We look at the system and any earlier reports.
  2. Inspection points are chosen and the ducts examined.
  3. We cover the area below and turn off the system.
  4. We clean the system and remove the debris from site.
  5. The report records what was cleaned, anything not reached and a next inspection date.

How to prepare

  • Arrange a key holder or contact on site
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Plan for cooking equipment or plant to be off before we arrive

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

Wherever a school like The Welldon Park Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Can ventilation in schools around South Harrow be cleaned out of term?

Yes. Half-terms and the summer break are the natural time for school work. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of South Harrow, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.

Will we have paperwork to show the system was cleaned?

Yes, both a certificate and a photo report. The report lists what was cleaned, anything not reached and the next inspection date.

Is South Harrow in your area?

Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, South Harrow included.

Do you inspect before cleaning?

Yes, on every job. The survey shows the layout, the access and the condition, so the quote is fixed before any work starts.

When should our ventilation next be cleaned?

That varies with the building, the filters and how hard the system works. Regular inspection tells you when it’s due.

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.

What types of premises do you cover?

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

Why it’s worth doing now in South Harrow

Dust in ducts does not go away on its own. Every year adds to the job, and more of it finds its way back into the building. In South Harrow, a planned overnight visit is much easier than closing unexpectedly.

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
