Ventilation duct cleaning in Cow Roast

Part by part

Supply ductwork

Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and it’s cleaned out through access panels.

Hospitals and care homes

Hospitals and care homes are occupied day and night. The work is sequenced with staff so care carries on.

Ventilation duct cleaning for kitchens and businesses in Cow Roast

We always start by inspecting. We look inside the ductwork at set points and record what’s there, then recommend cleaning where it’s needed. That keeps the work in proportion to the risk. Typical jobs include ductwork never cleaned since it was installed and systems with no record of inspection or cleaning, across offices and schools, hospitals and care homes and general extract ductwork.

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

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we’re called out for in Cow Roast

Many systems run for long hours, day after day, and every hour moves more dust through the ducts. Heavier use means faster build-up.

If you notice any of these, it’s worth a diagnosis:

  • Systems with no record of inspection or cleaning
  • Dirty diffusers dropping dust into rooms
  • Rooms that feel airless when the system runs
  • Blocked general extract ductwork

Ventilation work in and around Cow Roast is risk-based: inspect, then clean what needs it.

How to choose an extract cleaning contractor

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

Multi-site and managed buildings

We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Why act early in Cow Roast

Starting with an inspection means you only clean what needs it. Putting the inspection off just means you don’t know where you stand. It’s simpler to plan the work at Cow Roast now than to arrange it in a hurry later.

What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.

Why us?

  • Fixed quotes, normally within one working day
  • Work around your opening hours, with 24/7 emergency cover
  • A single point of contact for sites across the South East and London
  • We are fully insured

How the visit works

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a day or less for a small system and a series of visits for a large one. Somewhere as small as Cow Roast, the date and timings are agreed with you well before the day.

  1. We agree timings that suit the building, including evenings and weekends.
  2. Access panels are opened along each run.
  3. Before pictures are taken and the ducts cleaned section by section.
  4. Grilles and diffusers are cleaned and refitted.
  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
  • Let us know when the site is closed or quiet

What ventilation duct cleaning can’t fix

Ventilation duct cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:

  • Problems with how the system is controlled
  • A system that isn’t designed to move enough air
  • Leaks from roofs, pipes or walls into the ductwork

If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think before you book.

Questions from Cow Roast

Can you clean school ventilation in Cow Roast during the holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Cow Roast. Tell us your holiday dates and we will book the visit for when the site is empty.

Can the work in Cow Roast be done at night or at weekends?

Yes, out-of-hours work is a big part of what we do. It means the site in Cow Roast keeps running as normal. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.

What if parts of the system can’t be reached?

We record them on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.

Is a quote from photos possible?

Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.

What types of premises do you cover?

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

Can we book visits on a schedule?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

How long will the duct cleaning take?

Typically, the work takes a shift or two for a small system, longer for a whole building. Bigger sites are split into stages, to fit around the building.
