Ventilation duct cleaning in Thong

Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. We are often asked to deal with grilles and diffusers streaked with dirt and ductwork that hasn’t been inspected, across general extract ductwork, offices and schools and hospitals and care homes.

In a village or hamlet like Thong, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How the visit works

Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a shift or two for a small system, longer for a whole building. If the van will struggle with a lane or gateway near Thong, let us know and we will plan around it.

  1. We survey the system from drawings, pictures or a site visit.
  2. Inspection comes next, with pictures of the inside of the ducts.
  3. The area below is protected and the system switched off.
  4. Dust and debris are removed from ducts, grilles and diffusers.
  5. You get a TR19® certificate and photo report, with any unreached sections noted.

Before we arrive

  • Agree a time when the area can be out of use
  • Arrange a key holder or contact on site
  • Clear loose items from the work area

Ask for a quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Thong questions

Can you come to Thong after we close?

Yes, we can come after you close and finish before you open. Your customers, staff or residents in Thong needn’t be disturbed. Just call us on 0345 646 2711 or email us with your opening times and we’ll plan around them.

Can ventilation in schools around Thong be cleaned out of term?

Yes, holiday work suits schools best. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Thong. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we will fit the work in.

What information do you need?

A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.

Do you work in Thong?

Yes. Our area takes in London and the counties of South East England, and that includes Thong.

Can you come out in an emergency?

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 happens if parts of the ductwork cannot be reached?

The report shows exactly which parts weren’t reached. We can install panels to open those sections up.

How much does ventilation duct cleaning cost in Thong?

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

How long does ventilation cleaning take?

Typically, the work takes a weekend for a modest system, with large buildings phased floor by floor. Bigger sites are split into stages, to fit around the building.

Leave it or put it right?

After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. It’s worth booking a check, because nobody sees inside a duct day to day.

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 you will get one fixed quote.

What staff can safely do

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

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.

Signs you need ventilation duct cleaning in Thong

Building work is one of the biggest sources of debris in ducts, particularly if it’s left running while work goes on. Plaster, wood and masonry dust can sit in the ducts for years.

Any of these means the system needs a check-up:

  • Ventilation that needs a TR19® Air inspection
  • Blocked general extract ductwork
  • Ductwork never cleaned since it was installed
  • Ventilation full of debris from building work

For schools like Riverview Infant School, the holidays are the usual time to inspect and clean ventilation.

Questions to ask before you book

  • When the next visit should be, and why
  • Whether the quote is based on a survey or pictures
  • Whether the work can be done while the site is closed
  • Proof of insurance

Our hiring checklist

Keeping the system healthy

Think of this as the after-treatment advice, in brief:

  • Do not run the ventilation while builders are sanding or cutting
  • Report dust blowing from grilles straight away
  • Watch for water stains around grilles
  • Keep grilles and diffusers dusted

Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.

Don’t let construction dust into the ventilation by turning it off or covering the openings.

What a clean won’t put right

Some problems need a different service or another trade:

  • Ventilation that’s undersized for the building
  • Condensation caused by the building rather than the ducts
  • Damaged ductwork beyond cleaning

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

Parts of the system we cover

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

For landlords and multi-site operators

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
