Heronsgate questions
Do you work at weekends in Heronsgate?
Yes, out-of-hours work is a big part of what we do. The work in Heronsgate can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
Can you get to a site in Heronsgate?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Who is responsible for fire safety on the premises?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Can you quote from photos?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
When should our ventilation next be cleaned?
Inspection should decide it, in line with TR19® Air. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
How we handle ventilation duct cleaning in Heronsgate
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. If you have ventilation that needs a TR19® Air inspection and toilet and washroom extracts full of fluff, we can put it right.
In a village or hamlet like Heronsgate, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: 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 we’re called out for in Heronsgate
Ductwork is hidden above ceilings and in risers, so nobody sees the build-up. Grilles may be wiped, but the ducts behind them rarely are.
Any of these means the system needs a check-up:
- Construction dust left in ducts after a refit
- Dirty diffusers dropping dust into rooms
- Ductwork with too few access panels to clean
- Rooms that feel airless when the system runs
Wherever a school like Chorleywood Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- What happens if part of the system can’t be accessed
- Which accreditations they hold, and whether you can check them
- When they can work, and whether that’s outside your opening hours
- What records you’ll receive afterwards

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes anything from a single shift for a small office to a planned programme of nights for a large building, and we clear up before we go. Visits to a village like Heronsgate are booked in advance, at a time that suits whoever runs the site.
- We survey the system from drawings, photos or a site visit.
- Inspection comes next, with photos of the inside of the ducts.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- A certificate and before and after pictures follow, with anything not reached recorded.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one

Looking after it afterwards
After the visit, a few habits help the work last:
- Keep filters changed on time
- Report leaks or damp near ceilings and risers
- Flag any dust coming out of the vents
- Protect the system from construction dust
What was cleaned is listed, along with any parts that weren’t accessible, with pictures before and after. We will suggest where new access panels would help.
Fit access panels where the ductwork can’t be reached. The worst build-up tends to be where no one can look.
What a clean won’t put right
To be straight with you, there are a few things this work won’t fix:
- Controls and BMS faults that affect the system
- Ducts that are damaged, corroded or leaking and need replacing
- Damp or mould problems coming from the building fabric
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly.
