Ventilation duct cleaning in Langley Bottom
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It works by inspecting first and cleaning where the risk calls for it, so we look before we clean. Common call-outs are for dusty supply ductwork that hasn’t been cleaned in years and odours carried round the building by the ducts, on grilles and diffusers, hospitals and care homes and offices and schools.
In a village or hamlet like Langley Bottom, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What ventilation duct cleaning cannot fix
We will always give you a straight diagnosis, so here’s what ventilation duct cleaning won’t do:
- Controls and BMS faults that affect the system
- Damaged ductwork beyond cleaning
- Grease in kitchen extract systems, cleaned to TR19® Grease instead

What we do, step by step
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes from one overnight visit to a phased programme over several weeks. Seeing the system in photos first means the trip to Langley Bottom can be planned properly.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
How to prepare
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms

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.
Supply ductwork
Supply runs are inspected at set points first to see where cleaning is needed.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep grilles and diffusers dusted
- Keep filters changed on time
- Keep to the inspection interval in your report
- Make sure nothing is stacked against extract grilles
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Don’t let construction dust into the ventilation by switching it off or covering the grilles.
FAQs for Langley Bottom
Is Langley Bottom within the area you cover?
Yes, Langley Bottom is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you work overnight in Langley Bottom?
Yes, we can come after you close and finish before you open. That way a site in Langley Bottom doesn’t have to lose a day’s trading. Just call 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Who has the legal duty for fire safety?
The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you are not sure, check your lease and fire risk assessment.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How much time does a ventilation clean need?
Work on site takes anything from a single shift for a small office to a planned programme of nights for a large building. The survey gives us a clearer idea, so call us on 0345 646 2711 or send us an email to get started.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or drop us a line.
Can you quote from pictures?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If pictures aren’t enough, we will survey first.
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
