Ventilation duct cleaning in Calvert
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It’s risk-based and inspection-led, so every job starts with a look inside the ducts. The work covers grilles and diffusers, offices and schools and toilet extract systems, and people most often call us about toilet and washroom extracts full of fluff and ductwork with too few access panels to clean.
In a village or hamlet like Calvert, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What affects the cost of ventilation duct cleaning
The price is fixed before any work begins. It’s based on:
- How many systems or sites are involved
- The condition we find in the survey
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- The times we could work without disrupting the site
To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Part by part
Hospitals and care homes
In care settings, keeping dust contained is a priority. We protect the work area and take everything away.
Schools and colleges
Classrooms full of people, paper and coats produce plenty of dust. Inspection shows when cleaning is due.
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
When it’s something else
A few issues sit outside what this work can do:
- Leaking or broken duct sections
- Ventilation that’s undersized for the building
- Leaks from roofs, pipes or walls into the ductwork
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes a shift or two for a small system, longer for a whole building. Visits to a village like Calvert are booked in advance, at a time that suits whoever runs the site.
- We survey the system from drawings, pictures or a site visit.
- Ducts are inspected at access points and the condition recorded.
- Floors and furniture are covered and the ventilation turned off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or drop us a line.

Looking after it afterwards
To keep the system working properly between visits:
- Keep vents and grilles clear of shelving and stock
- Store cleaning certificates where auditors can find them
- Switch the ventilation off or cover grilles during dusty building work
- Wipe grilles and diffusers during routine cleaning
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Don’t let construction dust into the ventilation by turning it off or covering the openings.

Common questions in Calvert
Do you cover Calvert for ventilation duct cleaning?
Yes. We work across London and the South East, and Calvert is part of that. Just phone us on 0345 646 2711 or use the quote form with a few details of the site.
Do you cover smaller places like Calvert?
Yes. Villages and rural sites across the South East are part of our work, Calvert included. A survey first, from photos or a visit, means we arrive with the right kit.
Will you look at the ducts before quoting?
Yes. Every job is surveyed first, from pictures, drawings or a site visit, then we give you a fixed quote.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How often should ventilation ductwork be cleaned?
That varies with the building, the filters and how hard the system works. Regular inspection tells you when it’s due.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Will we have to shut during the visit?
Not typically. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.
Is a quote from photos possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
