About our ventilation duct cleaning in Ash
When the work is finished, you get a TR19® certificate and before and after photos. It shows what was cleaned, anything we couldn’t reach and when the system should next be inspected, so you have it all on record. If you have odours carried round the building by the ducts and ductwork never cleaned since it was installed, we can put it right.
Around a place like Ash, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Questions from Ash
Do you work at weekends in Ash?
Yes, we can come after you close and finish before you open. It means the site in Ash keeps running as normal. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Can ventilation in schools around Ash be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 19 schools, colleges and universities with registered kitchens within about a mile and a half of Ash. Just call us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
How often do ventilation ducts need cleaning?
There’s no single interval; under TR19® Air, inspection decides. We suggest a next inspection date after each visit.
What does TR19 Air cover?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, rather than kitchen extract. It’s risk-based and led by inspection, while TR19® Grease covers kitchen extract systems.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Common problems we fix in Ash
Ductwork is hidden above ceilings and in risers, so dust collects unseen. Grilles may be wiped, but the ducts behind them rarely are.
Any of these means the system needs a check-up:
- Musty smells from the ventilation
- Dirty diffusers dropping dust into rooms
- Extract ducts clogged with lint and dust
- Stuffy rooms and stale air
Classrooms and halls at schools such as Walsh CofE Junior School are easiest to work in when pupils are away.

Why it’s worth doing now in Ash
Starting with an inspection means you only clean what needs it. Skipping it leaves you guessing. Light use slows the build-up but doesn’t stop it.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.

What affects the quote in Ash
The survey tells us what the work involves. The main factors are:
- How easy every part is to reach
- Site rules, permits and inductions
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Wide pictures of the system and the area around it
- Where the site is and what kind of site it is
- Any access panels or hatches you can see

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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, and that is where we come in.
Ash buildings and their air
Food Standards Agency data includes about 19 schools, colleges and universities and about 13 care, childcare and hospital premises across Ash and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 4.8 miles east of Ash is Guildford Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Ash is about 32 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
If you manage offices or shops near Ash station, their ventilation can be inspected and cleaned out of hours. If you run a surgery, dental practice or care home near Ash, clean ventilation matters as much to you as to a hospital like Guildford Hospital (about 4.8 miles east).
Ash is about 2 miles east of Aldershot, in Surrey. We carry out ventilation duct cleaning for commercial premises of every kind in Ash and the rest of Surrey.

Whether your site is on Ash Church Road, Square Field Way and Littlefield Close or a nearby road, our technicians can take on the work.

Well-known places in the area include Farnham Castle (4 miles south-west) and Ash Museum (under half a mile north-east). For a walk, there’s Rowhill Nature Reserve and Hog's Back.
What the work involves, part by part
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, which makes dirt stick. They’re cleaned and their condition recorded.
Schools and colleges
The work is fitted around term dates and events and agree access with the site team.
How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from one overnight visit to a phased programme over several weeks. Because the survey comes first, a visit to Ash can normally be finished without a second trip.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- After photos are taken and the certificate and report issued.
Getting ready for the visit
- Move anything stored near the system
- Tell us about site rules, permits or sign-in
