About our ventilation duct cleaning in Flamstead
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’re dealing with dust marks around grilles and ceiling diffusers and duct runs that can’t be reached for cleaning, we can put it right, from hospitals and care homes, offices and schools and general extract ductwork onwards.
Somewhere as small as Flamstead, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with photos follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

What affects the quote in Flamstead
Every site gets its own quote. These are the things that affect it:
- Access, including roofs, risers and ceiling voids
- The condition of the system
- How many systems or sites are involved
- Travel, parking and unloading
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.
Asking for a quote
To help us quote quickly, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Your last certificate, test record or report
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, before work begins.
Different parts, different methods
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. Clearing the duct helps the fan do its job.
Schools and colleges
Classrooms full of people, paper and coats produce plenty of dust. Inspection shows when cleaning is due.

Do you need ventilation duct cleaning in Flamstead?
Many systems run for long hours, day after day, and every hour of running brings more dust with it. Heavier use means faster build-up.
Look out for these warning signs:
- Musty smells from the ventilation
- Ventilation that needs a TR19® Air inspection
- Construction dust left in ducts after a refit
- Dust marks around grilles and ceiling diffusers
Healthcare buildings such as Hemel Hempstead Hospital, about 5 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Flamstead, yours matters too.

How the visit works
There are three stages on the day: 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 weekend for a modest system, with large buildings phased floor by floor. The timing of a visit to Flamstead is set by you, and the travel is our side of the planning.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After pictures are taken and the certificate and report issued.
Preparing for the visit
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
How to get a quote
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.
Advice
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Keep filters changed on time
- Keep grilles and diffusers dusted
- Keep vents and grilles clear of shelving and stock
- Get leaks near ductwork fixed quickly
Pass the paperwork to your facilities or maintenance team, so it’s all in one place. Over time, it shows how quickly the system gets dirty.
Regular inspection is the core of TR19® Air. Scheduled inspections spot dust before it becomes a major job.
