Ventilation duct cleaning in Clewer
In a building in Clewer, the people inside spend hours breathing what the ventilation delivers. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. The work covers supply ductwork, offices and schools and general extract ductwork, and people most often call us about stuffy rooms and stale air and grilles and diffusers streaked with dirt.
Smaller buildings around Clewer often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Common questions in Clewer
Can you get to a site in Clewer?
Yes. Clewer is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you clean school ventilation in Clewer during the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 55 schools, colleges and universities with registered kitchens within about a mile and a half of Clewer. Just give us a ring on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Is TR19 a legal requirement?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What happens if parts of the ductwork can’t be reached?
Accessible sections are cleaned and the others recorded. Extra access panels can solve it, and we can fit them.
Do you provide a report?
Yes. You get a TR19® certificate and a report with before and after photos. Keep them in the maintenance log.
Will you look at the ducts before quoting?
Yes. We always survey first, on site or from pictures and drawings, and then quote a fixed price.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Between visits
To keep the system working properly between visits:
- Diary the next TR19® Air inspection
- Wipe grilles and diffusers during routine cleaning
- Report leaks or damp near ceilings and risers
- Log every filter change
If there’s building work planned, protect the ventilation. Turn off the system or cover the openings during dusty jobs.
Fix leaks and damp near the ductwork quickly, as moisture makes dust stick.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Windsor and Maidenhead. Larger estates can be phased building by building to keep disruption down.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
What the work involves, part by part
Supply ductwork
Anything in a supply duct can end up in the rooms it feeds. Cleaning it deals with the source.
Extract ductwork
Toilet and washroom extract can carry moisture as well as dust, which makes dirt stick. We clean them and note any damp or corrosion.
What ventilation duct cleaning can’t fix
We will always give you a straight diagnosis, so here’s what ventilation duct cleaning will not do:
- Building management settings that run the plant
- Condensation caused by the building rather than the ducts
- Leaking or broken duct sections
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
Parts of the system we cover
- Hospitals and care homes
- Offices and schools
- General extract ductwork
- Supply ductwork
- Grilles and diffusers
- Toilet extract systems
Common problems we fix in Clewer
Many systems run for long hours, day after day, and every hour moves more dust through the ducts. Heavier use means faster build-up.
It’s time to book a visit if you see:
- Construction dust left in ducts after a refit
- Ductwork with too few access panels to clean
- Dusty supply ductwork that hasn’t been cleaned in years
- Ductwork that hasn’t been inspected
If you manage shops or offices close to Windsor & Eton Central station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Before you book anyone
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the figure could change on the day
- Exactly which parts of the system are covered
- Proof of insurance
What we do, step by step
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. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes a shift or two for a small system, longer for a whole building. Because the survey comes first, a visit to Clewer can normally be finished without a second trip.
- We start by looking at the layout of the ductwork and how it can be reached.
- Inspection comes next, with pictures of the inside of the ducts.
- The area below is protected and the system switched off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Before we arrive
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
- Clear the space around the work
Get a fixed quote
For a fixed quote, ring 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
