Ventilation duct cleaning in Coldblow, done properly
Supply ducts carry air into the rooms and extract ducts take it away. Over time, both collect dust and debris, some of which ends up back in the rooms. We clean the ductwork, grilles and diffusers to TR19® Air. If you have ventilation that needs a TR19® Air inspection and duct runs that can’t be reached for cleaning, we can help.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Coldblow, dust and debris build up in the units and ductwork over time.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How it works
We turn up 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 before work begins, and the area around the work is covered and protected. The work itself takes a shift or two for a small system, longer for a whole building. Loading bays, visitor permits and roof access are the first things we ask about for a site in Coldblow.
- We survey the system from drawings, photos or a site visit.
- Inspection comes next, with pictures of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned 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.
Preparing for the visit
- Find the previous report, if there is one
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Get leaks near ductwork fixed quickly
- Flag any dust coming out of the vents
- Don’t run the ventilation while builders are sanding or cutting
- File each ventilation report with the building records
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Put it in the diary now so it does not slip.
Protect the system during building work by turning it off or covering the openings.
