How we handle ventilation duct cleaning in Ashley Green
TR19® Air is the part of BESA’s TR19® that deals with general supply and extract ventilation. It’s risk-based and inspection-led, so we look before we clean. The work covers supply ductwork, toilet extract systems and general extract ductwork, and people most often call us about supply ducts with years of dust inside and ventilation full of debris from building work.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Different parts, different methods
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, which makes dirt stick. They’re cleaned and their condition recorded.
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. We clean them as part of the job, so dust on them is not blown back in.
Ventilation in Ashley Green buildings
The FSA’s food hygiene register lists about 4 schools, colleges and universities and about 8 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within roughly a mile and a half of the centre of Ashley Green. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 5 miles east of Ashley Green is Hemel Hempstead Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. About 27 miles out from central London, Ashley Green is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
Healthcare buildings such as Hemel Hempstead Hospital, about 5 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Ashley Green, yours matters too.

Fixed quotes for ventilation duct cleaning in Ashley Green
Sites vary more than people expect. What affects the quote:
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- The condition of the system
- Parking and loading at the site
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
- Your opening hours and when the area is out of use
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Common questions in Ashley Green
Can you come to Ashley Green after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Ashley Green does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you work in villages like Ashley Green?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How long does ventilation cleaning take?
Work on site takes a weekend for a modest system, with large buildings phased floor by floor. We’ll know more after the survey, so phone us on 0345 646 2711, or email photos to get started.
How often do ventilation ducts need cleaning?
Inspection should decide it, in line with TR19® Air. Busy or sensitive buildings may need it more often.
Do you clean grilles and diffusers?
Yes. Removable grilles come down for cleaning and go back up. The rest are cleaned where they are.
Will you look at the ducts before quoting?
Yes. We always survey first, on site or from photos and drawings, then we send you a fixed quote.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. If photos are not enough, we will survey first.
What happens if it’s left?
Starting with an inspection means you only clean what needs it. Skipping it leaves you guessing. 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. Mention every system or site you need covered, and you’ll get one fixed quote.

What we do, step by step
A visit follows the same order every time: protect the area, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes a shift or two for a small system, longer for a whole building. For a village or hamlet like Ashley Green, tell us about narrow lanes, gates and parking when you book.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with pictures of the inside of the ducts.
- The area below is protected and the system switched off.
- Dust and debris are removed from ducts, grilles and diffusers.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what ventilation duct cleaning won’t do:
- Problems with how the system is controlled
- Damaged ductwork beyond cleaning
- Cooking extract ducts, which are a separate specialist clean
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think before you book.
Parts of the system we cover
- Offices and schools
- Toilet extract systems
- Grilles and diffusers
- Supply ductwork
- Hospitals and care homes
- General extract ductwork
Looking after it afterwards
Once we have finished, these simple steps help:
- Diary the next TR19® Air inspection
- Wipe grilles and diffusers during routine cleaning
- Store cleaning certificates where auditors can find them
- Get leaks near ductwork fixed quickly
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.

Common problems we fix in Ashley Green
Ventilation hygiene often gets left out of planned maintenance. A building in Ashley Green can have well-serviced plant and dirty ductwork at the same time.
Clients usually contact us when they notice one of these:
- Duct runs that cannot be reached for cleaning
- Systems with no record of inspection or cleaning
- Construction dust left in ducts after a refit
- Grilles and diffusers streaked with dirt
Wherever a school like Ashlyns School has ducted ventilation, a half-term visit keeps the work out of lesson time.
