Ventilation duct cleaning across Thornton Heath

Ventilation duct cleaning in Thornton Heath

Ventilation duct cleaning is something we carry out for buildings in Thornton Heath and right across Greater London, from offices and schools to hospitals, care homes and shops. Every job begins with a survey and a fixed quote. The work covers supply ductwork, grilles and diffusers and offices and schools, and the jobs we see most are ventilation that needs a TR19® Air inspection and supply ducts with years of dust inside.

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

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Landlords, agents and facilities managers

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Questions from Thornton Heath

Can you clean school ventilation in Thornton Heath during the holidays?

Yes. The holidays are the usual time for school work. The FSA’s register shows about 39 schools and colleges with food registrations within roughly a mile and a half of Thornton Heath. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we will fit the work in.

How do you handle parking and loading in Thornton Heath?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit typically gets round them.

Do you offer emergency callouts?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Do we need to close while you work?

Typically not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.

Can you price the work without visiting?

Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

Which kinds of sites do you work on?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

What is TR19® Air?

The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. Under TR19® Air, inspection decides when cleaning is needed.

Can you look after several sites?

Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.

Different parts, different methods

Schools and colleges

Schools and colleges are easiest to clean during the holidays, with nobody in the classrooms.

Hospitals and care homes

Patients and residents may be more sensitive to dust in the air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.

Ventilation duct cleaning around Thornton Heath

The FSA’s food hygiene register lists about 39 schools, colleges and universities, about 136 hospitals, care homes and childcare premises and about 10 hotels and guest houses with registered kitchens or food service across Thornton Heath and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Thornton Heath’s nearest hospital, Croydon University Hospital, is about 0.7 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is typically done out of hours.

Croydon University Hospital, about 0.7 miles south, is the nearest hospital to Thornton Heath, and healthcare sites of every size need their supply air kept clean. If you manage shops or offices close to Thornton Heath station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What a clean won’t put right

We won’t sell you work that doesn’t address the problem, so here are the limits:

  • Ducts that are damaged, corroded or leaking and need replacing
  • Leaks from roofs, pipes or walls into the ductwork
  • Building management settings that run the plant

If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.

What the work covers

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

In-house cleaning or a specialist?

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

Looking after it afterwards

To keep the system working properly between visits:

  • Report dust blowing from grilles right away
  • Include grilles in the cleaning rota
  • Protect the system from construction dust
  • Keep the TR19 certificate and photo report in the maintenance log

Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.

Don’t let construction dust into the ventilation by switching it off or covering the grilles.

How the visit works

Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a day or less for a small system and a series of visits for a large one. Expect the work in Thornton Heath to happen after your last customer leaves, not during trading.

  1. We agree timings that suit the building, including evenings and weekends.
  2. We open the ductwork through its access panels.
  3. Before photos are taken and the ducts cleaned section by section.
  4. We clean the grilles and diffusers and put them back.
  5. We take after pictures and send the certificate and report.

Getting ready for the visit

  • Name a contact who can let us in at the agreed time
  • Have your last certificate or report to hand
  • Let us know how we reach the system, including roofs, risers and plant rooms

When to call us in Thornton Heath

Damp ducts hold onto dirt. Where there’s condensation or a leak, dust clings and builds faster, which is harder to shift later.

Keep an eye out for these warning signs:

  • Odours carried round the building by the ducts
  • Rooms that feel airless when the system runs
  • Blocked general extract ductwork
  • Dirty diffusers dropping dust into rooms

If you manage a school such as Winterbourne Junior Girls' School, ventilation cleaning is best booked for the holidays.

Questions to ask before you book

  • Whether the figure could change on the day
  • Whether inaccessible sections are listed on the report
  • Proof of accreditation you can verify
  • Whether the work can be done while the site is closed
