Ventilation duct cleaning in South Street

How we handle ventilation duct cleaning in South Street

Extract ducts from toilets, changing rooms and general areas collect dust and lint. Supply ducts pick up whatever gets past the filters. Both are cleaned, with the area protected and the mess contained. Common call-outs are for ductwork never cleaned since it was installed and odours carried round the building by the ducts, across hospitals and care homes, toilet extract systems and supply ductwork.

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 South Street.

Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

When something else is needed

We’d rather tell you now than book work that will not help, so here are the limits:

  • Ducts that are damaged, corroded or leaking and need replacing
  • Damp or mould problems coming from the building fabric
  • Controls and BMS faults that affect the system

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

Where we work

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

Why it’s worth doing now in South Street

Starting with an inspection means you only clean what needs it. Skipping it leaves you guessing. In South Street, as across London, ductwork often passes through shared risers and other people’s space.

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or drop us a line, and we will explain what it covers.

Part by part

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.

Grilles and diffusers

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

For landlords and multi-site operators

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.

We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building to keep disruption down.

What your team can do, and what needs us

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

In-house cleaning and specialist cleaning do different jobs. 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.

How the visit works

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes a shift or two for a small system, longer for a whole building. Expect the work in South Street to happen after your last customer leaves, not during trading.

  1. First we check the layout and any past paperwork.
  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. We report on the work, listing any inaccessible sections and the next inspection date.

Before we arrive

  • Tell us about site rules, permits or sign-in
  • Name a contact who can let us in at the agreed time
  • Move anything stored near the system

South Street buildings and their air

Going by the FSA’s register, there are about 5 hospitals, care homes and childcare premises serving food within roughly a mile and a half of the centre of South Street. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 3.2 miles south of South Street is Tandridge Priory, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. London plant rooms are often on roofs or in basements reached through occupied floors.

Healthcare ventilation, from large hospitals like Tandridge Priory (about 3.2 miles south) to small clinics, depends on clean filters, coils and ducts. For schools like Charles Darwin School, the holidays are the usual time to inspect and clean ventilation.

South Street is about 4 miles north-east of Oxted, in Greater London.

Your questions about ventilation duct cleaning in South Street

Can you do ventilation duct cleaning in South Street?

Yes. We work across London and the South East, and South Street is part of that. Get in touch with the details and we will arrange a survey.

Do you work at weekends in South Street?

Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.

Can you set up regular visits?

Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.

Do you survey before quoting?

Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

How often should ventilation ductwork be cleaned?

TR19® Air is risk-based, so cleaning follows inspection rather than a fixed calendar. Each report recommends when the system should next be inspected.

Can you price the work without visiting?

Usually, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. Some sites still need a visit, and we’ll say so.

How far ahead should we book?

It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

Looking after it afterwards

After the visit, a few habits help the work last:

  • Report dust blowing from grilles right away
  • Make sure nothing is stacked against extract grilles
  • Store cleaning certificates where auditors can find them
  • Watch for water stains around grilles

The report lists the sections we cleaned and any we couldn’t reach, with photos before and after. If access panels are needed, we will say where.

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