Ventilation duct cleaning in Great Oakley
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. The work covers offices and schools, hospitals and care homes and grilles and diffusers, and common reasons people get in touch are duct runs that can’t be reached for cleaning and grilles and diffusers streaked with dirt.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
FAQs for Great Oakley
Can a school’s ventilation in Great Oakley be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Great Oakley. Just ring 0345 646 2711, or email photos with your term dates and we will plan around them.
Can you come to Great Oakley after we close?
Yes, nights and weekends are routine for us. It means the site in Great Oakley keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Do you provide a report?
Yes. You get a certificate with the date, location and technician, along with pictures before and after.
When should our ventilation next be cleaned?
Inspection should decide it, in line with TR19® Air. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How do you deal with ducts you cannot get into?
Accessible sections are cleaned and the others recorded. Fitting access panels tends to be the answer, and we can quote for them.
How long does ventilation cleaning take?
Typically, the work takes a day or less for a small system and a series of visits for a large one. Large buildings can be phased, often out of hours, to fit around the building.
Between visits
So the system stays in good health:
- Wipe grilles and diffusers during routine cleaning
- Book the next inspection on the date the report recommends
- Keep the TR19 certificate and photo report in the maintenance log
- Switch the ventilation off or cover grilles during dusty building work
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.
Deal with condensation and leaks near ducts promptly, as moisture makes dust stick.
Why it’s worth doing now in Great Oakley
Leave dust in the ductwork and it keeps building. The longer it’s left, the more there is to remove, and the more gets blown back into the rooms. Systems in rural buildings are often out of sight and out of mind.
The cost depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

How the job changes from site to site
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. A clean duct takes the load off.
Offices and retail
Offices and shops tend to need the work done outside opening hours so staff and customers are not disturbed.
What affects the quote in Great Oakley
Some jobs are bigger than they look, and some smaller. The main factors:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- A single visit or a regular plan
- Travel, parking and unloading
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or email us, and we will explain what it covers.
What to send for a quote
What to send for a quote:

What else we do in Great Oakley
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes a weekend for a modest system, with large buildings phased floor by floor. Seeing the system in photos first means the trip to Great Oakley can be planned properly.
- 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.
- 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
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Clear loose items from the work area
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, call us on 0345 646 2711 or use the quote form.
