Ventilation duct cleaning in Bengeo, done properly
We always start by inspecting. The ducts are opened at access points and the condition recorded, then recommend cleaning where it’s needed. That way the work matches the real condition. If you have ductwork never cleaned since it was installed and ventilation full of debris from building work, we can help.
In a place like Bengeo, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a shift or two for a small system, longer for a whole building, and the area is cleaned down before we leave. Because the survey comes first, a visit to Bengeo can usually be finished without a second trip.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- We take after pictures and send the certificate and report.
Before we arrive
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Wipe grilles and diffusers during routine cleaning
- Report leaks or damp near ceilings and risers
- Flag any dust coming out of the vents
- Diary the next TR19® Air inspection
The report includes a recommended date for the next inspection, based on what we found. Put it in the diary now so it isn’t missed.
Deal with condensation and leaks near ducts promptly, as wet dust is much harder to clean.
Bengeo: your questions answered
Can you come to Bengeo after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Bengeo doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Can you clean school ventilation in Bengeo during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 22 schools and colleges with food registrations within roughly a mile and a half of Bengeo. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Will you look at the ducts before quoting?
Yes. TR19® Air is inspection-led, so we look inside the ducts at set points, with photos of the inside. We recommend cleaning where the inspection shows it’s due.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How does TR19 Air differ from TR19 Grease?
TR19® Air applies to the general ventilation in buildings like offices, schools and hospitals. Kitchen extract systems fall under TR19® Grease instead.
Will we have to shut during the visit?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Will you clean the vents in the rooms?
Yes. We clean the grilles and diffusers along with the ductwork, so the room side is clean too.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Honest limits
Some problems need a different service or another trade:
- Condensation caused by the building rather than the ducts
- Damaged ductwork beyond cleaning
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
If you’re not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

Do you need ventilation duct cleaning in Bengeo?
In a building in Bengeo, the ventilation may run for long hours every day, and every hour of running brings more dust with it. The busier the building, the faster it builds up.
Common reasons sites call us are:
- Ductwork that hasn’t been inspected
- Grilles and diffusers streaked with dirt
- Ductwork with too few access panels to clean
- Ductwork never cleaned since it was installed
If you manage shops or offices close to Hertford East station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Questions to ask before you book
- Proof of insurance
- Whether the figure could change on the day
- Exactly which parts of the system are covered
- Whether the quote is based on a survey or pictures

What the work involves, part by part
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
Grilles and diffusers
Dust marks around grilles can point to dirt further back in the system. The grilles are cleaned and the ducts behind inspected.
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
