Common problems we fix in Ayot Green

Filters never catch everything, so fine dust settles in supply ductwork over the years. Extract ducts collect whatever the rooms give off: dust, fibres and lint.

Common reasons sites call us are:

  • Ductwork with too few access panels to clean
  • Systems with no record of inspection or cleaning
  • Dirty diffusers dropping dust into rooms
  • Construction dust left in ducts after a refit

School buildings such as Monk's Walk School are usually done in the holidays, so classrooms are not disturbed.

Comparing quotes

  • Whether the work can be done while the site is closed
  • Whether inaccessible sections are listed on the report
  • If the quote is a fixed price or an estimate
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

How we handle ventilation duct cleaning in Ayot Green

Ductwork is reached through access panels at intervals along the system. Where there are not enough panels to reach every section, we note the uncleaned parts in the report, and new access panels can be installed so they’re covered next time. The work covers hospitals and care homes, supply ductwork and offices and schools, and common reasons people get in touch are odours carried round the building by the ducts and blocked general extract ductwork.

For a building in or near Ayot Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Staff cleaning versus specialist work

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

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 can diagnose it and quote.

When something else is needed

A few issues sit outside what this work can do:

  • Damaged ductwork beyond cleaning
  • Damp or mould problems coming from the building fabric
  • A system that is not designed to move enough air

If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.

What the work covers

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

Keeping the system healthy

Results last longer with the right care. Here’s what we suggest:

  • Protect the system from construction dust
  • Make sure nothing is stacked against extract grilles
  • Book the next inspection on the date the report recommends
  • Keep filters changed on time

Pass the paperwork to your facilities or maintenance team, so the history stays together. Over time, it shows how quickly the system gets dirty.

Protect the system during building work by turning it off or covering the openings.

Landlords, agents and facilities managers

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

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

What affects the cost of ventilation duct cleaning

You’ll get a fixed price before work begins. It takes into account:

  • The condition we find in the survey
  • The number of sites or systems
  • Where the site is and how we reach it
  • How easy every part is to reach

Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Helping us quote

We can often survey from pictures. Try to include:

  • The paperwork from the last visit, if you have it
  • Your opening hours and when the area is out of use
  • Close-ups of filters, grilles, hatches or access panels
  • Problems your staff have spotted

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.

What happens on the day

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Visits to a village like Ayot Green are booked in advance, at a time that suits whoever runs the site.

  1. We look at the system and any earlier reports.
  2. We inspect the ducts at chosen points to see where cleaning is needed.
  3. The work area is protected and the system switched off.
  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.

How to prepare

  • Clear loose items from the work area
  • Have your last certificate or report to hand
  • Tell us about site rules, permits or sign-in

Get a fixed quote

We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.
