Ventilation duct cleaning in Letchworth, done properly
Toilet, washroom and general extract ducts gather dust, fluff and debris. Supply ducts pick up whatever gets past the filters. Both are cleaned, with the area protected and the mess contained. If you have dust marks around grilles and ceiling diffusers and systems with no record of inspection or cleaning, we can help.
Buildings in towns like Letchworth often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Multi-site and managed buildings
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
What the work involves, part by part
Supply ductwork
Supply ducts carry air from the AHU into the rooms. Dust that slips past the filters builds up inside, and we remove it through access panels.
Hospitals and care homes
Dust control matters during work in occupied care settings. We protect the work area and take everything away.
Do you need ventilation duct cleaning in Letchworth?
In a building in Letchworth, the ventilation may run for long hours every day, and every hour moves more dust through the ducts. The busier the building, the faster it builds up.
Common reasons sites call us include:
- Toilet and washroom extracts full of fluff
- Ventilation that needs a TR19® Air inspection
- Damp or stale smells from grilles
- Dust marks around grilles and ceiling diffusers
If you run an office near Letchworth Garden City station, its supply ductwork can gather dust for years before anyone looks inside.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Report leaks or damp near ceilings and risers
- Keep vents and grilles clear of shelving and stock
- Keep the TR19 certificate and photo report in the maintenance log
- Keep to the inspection interval in your report
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Protect the system during building work by turning it off or covering the openings.
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from a single shift for a small office to a planned programme of nights for a large building. In a town like Letchworth, we normally work after closing or on a quiet day, so the site opens again on time.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with photos of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time
- Make sure equipment near the work can be switched off and left to cool

Common questions in Letchworth
Can you work in Letchworth outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Letchworth does not have to lose a day’s trading. Just give us a ring on 0345 646 2711 or email us with your opening times and we’ll plan around them.
Can ventilation in schools around Letchworth be cleaned out of term?
Yes, out-of-term visits are normal for schools. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Letchworth, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with photos where possible, and we explain what access is needed, for example new access panels.
Do you inspect before cleaning?
Yes, always. The survey shows the layout, the access and the condition, so the quote is fixed before any work starts.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
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 insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
