Common questions in Thornhill
Can you get to a site in Thornhill?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Do you work overnight in Thornhill?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Thornhill needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
How long will the duct cleaning take?
It takes anything from a single shift for a small office to a planned programme of nights for a large building. The size of the system and the access make the biggest difference.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Can you quote from photos?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
Do we lose a day’s trading?
Not normally. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Will you look at the ducts before quoting?
Yes. Inspection is the start of the TR19® Air approach and record what we find. Cleaning is recommended where it’s needed.
Ventilation duct cleaning for kitchens and businesses in Thornhill
When the work is finished, you get a TR19® certificate and before and after photos. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. Common call-outs are for construction dust left in ducts after a refit and musty smells from the ventilation, across general extract ductwork, supply ductwork and toilet extract systems.
In a place like Thornhill, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

How the job changes from site to site
Extract ductwork
Washroom extracts handle damp air, so the dust tends to cling. We clean them and note any damp or corrosion.
Grilles and diffusers
Where they come out, grilles are taken down and cleaned, then put back.
Ventilation in Thornhill buildings
There are about 29 schools, colleges and universities and about 35 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in Thornhill and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1.4 miles north-east of Thornhill is Moorgreen Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like Thornhill Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Thornhill is about 2 miles east of Southampton, in Southampton. We provide ventilation duct cleaning for businesses, landlords and public buildings in Thornhill and the rest of Southampton. Our Southampton coverage runs to 40 places, Thornhill among them.

Common problems we fix in Thornhill
Ventilation hygiene often gets left out of planned maintenance. A building in Thornhill can have well-serviced plant and dirty ductwork at the same time.
Keep an eye out for any of the following:
- Ducts that need a clean before handover
- Damp or stale smells from grilles
- Supply ducts with years of dust inside
- Dust marks around grilles and ceiling diffusers
If you run a surgery, dental practice or care home near Thornhill, clean ventilation matters as much to you as to a hospital like Moorgreen Hospital (about 1.4 miles north-east).

Fixed quotes for ventilation duct cleaning in Thornhill
Some jobs are bigger than they look, and some smaller. The main factors:
- Site requirements such as sign-in and permits
- The number of sites or systems
- The scale of the work
- The condition of the system
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
Helping us quote
When you contact us, it’s useful to have:
- The times we could work without disrupting the site
- Wide pictures of the system and the area around it
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then phone us on 0345 646 2711, or send details by email.
What happens on the day
We work around your opening hours, not the other way round. 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 a weekend for a modest system, with large buildings phased floor by floor. Because the survey comes first, a visit to Thornhill can usually be finished without a second trip.
- We start by looking at the layout of the ductwork and how it can be reached.
- Ducts are inspected at access points and the condition recorded.
- The area below is protected and the system switched off.
- Dust and debris are removed from ducts, grilles and diffusers.
- A certificate and before and after photos follow, with anything not reached recorded.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.

What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
When your team notices a problem 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.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
What ventilation duct cleaning cannot fix
Before booking, it helps to know what’s not included:
- Damaged ductwork beyond cleaning
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Damp or mould problems coming from the building fabric
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly.
