About our ventilation duct cleaning in Potten End
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, alongside filter changes and AHU maintenance. If you’re dealing with toilet and washroom extracts full of fluff and supply ducts with years of dust inside, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a written report, dated and illustrated with pictures, 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 your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Stick to the filter change schedule
- Diary the next TR19® Air inspection
- Report leaks or damp near ceilings and risers
- Keep grilles and diffusers dusted
You get a TR19® certificate and a photo report after the clean. Keep them in the maintenance log, with the date, location and technician recorded.
Do not let construction dust into the ventilation by turning it off or covering the openings.
What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes anything from a single shift for a small office to a planned programme of nights for a large building. In a small place like Potten End, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Before we arrive
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Signs you need ventilation duct cleaning in Potten End
It matters for the people inside: dirt in the ducts can come back out of the grilles, slow the air and add strain on fans. In hospitals, care homes and schools, clean air is especially important.
If you notice any of these, it’s worth a diagnosis:
- Ducts that need a clean before handover
- Grilles and diffusers streaked with dirt
- Blocked general extract ductwork
- Systems missing access panels
Hemel Hempstead Hospital, about 2.7 miles south-east, is the nearest hospital to Potten End, and healthcare sites of every size need their supply air kept clean.

Questions from Potten End
Can you come to Potten End after we close?
Yes. We work evenings, overnight and at weekends. The work in Potten End can fit around your hours. Your opening times are the first thing we ask for.
Do you work in villages like Potten End?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Can you set up regular visits?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
How often do ventilation ducts need cleaning?
Under TR19® Air, the answer comes from inspecting the ducts. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
How much does ventilation duct cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
Will we have to shut during the visit?
Not usually. 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.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Honest limits
In fairness, there are a few things this work won’t fix:
- Condensation caused by the building rather than the ducts
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Controls and BMS faults that affect the system
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly.
Parts of the system we cover
- Supply ductwork
- General extract ductwork
- Grilles and diffusers
- Hospitals and care homes
- Offices and schools
- Toilet extract systems
Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
What affects the cost of ventilation duct cleaning
Sites vary more than people expect. The main factors:
- The times the site is available
- How many systems or sites are involved
- The condition of the system
- How easy every part is to reach
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
