Managing agents and facilities teams in Mackerye End
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Ventilation duct cleaning in Mackerye End, done properly
Dust in ventilation ductwork is not only a cleanliness issue. It slows the air, strains the fans and can be blown back out of the grilles. Cleaning restores the clear airway the system was designed with. The work covers hospitals and care homes, offices and schools and toilet extract systems, and people most often call us about ventilation full of debris from building work and grilles and diffusers streaked with dirt.
Somewhere as small as Mackerye End, 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.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Between visits
How long the results last depends on use and care. We suggest:
- Diary the next TR19® Air inspection
- Keep vents and grilles clear of shelving and stock
- Keep filters changed on time
- Store cleaning certificates where auditors can find them
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Fix leaks and damp near the ductwork quickly, as moisture makes dust stick.

When to call us in Mackerye End
Even good filters let some dust through, so fine dust settles in supply ductwork over the years. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
Look out for these warning signs:
- Stuffy rooms and stale air
- Extract ducts clogged with lint and dust
- Musty smells from the ventilation
- Dust marks around grilles and ceiling diffusers
Healthcare buildings such as St Albans City Hospital, about 4.8 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Mackerye End, yours matters too.

What the work involves, part by part
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. A clean duct takes the load off.
Schools and colleges
Schools and colleges are easiest to clean during the holidays, when classrooms are empty.
Questions from Mackerye End
Is Mackerye End within the area you cover?
Yes, we work in villages as well as towns, and Mackerye End is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in Mackerye End outside opening hours?

Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Does the law say we must follow TR19?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
