- Building management settings that run the plant
- Leaks from roofs, pipes or walls into the ductwork
- Ventilation that’s undersized for the building
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think.

How we handle ventilation duct cleaning in Blacknest
We get into the ducts through access panels along each run. If some sections can’t be reached, the report says so, and new access panels can be installed so they’re covered next time. If you have ducts that need a clean before handover and extract ducts clogged with lint and dust, we can help.
For a building in or near Blacknest, access is agreed in advance and the visit is planned around the journey.
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.

Why act early in Blacknest
Facilities teams are regularly asked to show evidence of ventilation hygiene. A TR19® certificate and photo report from a recent clean give them that. Out of sight is the usual reason a rural system goes too long without attention.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep the TR19 certificate and photo report in the maintenance log
- Wipe grilles and diffusers during routine cleaning
- Report dust blowing from grilles straight away
- Watch for water stains around grilles
What was cleaned is listed, along with any parts that weren’t accessible, backed up by before and after pictures. If access panels are needed, we will say where.
Fit access panels where the ductwork cannot be reached. The worst build-up tends to be where no one can look.
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a shift or two for a small system, longer for a whole building. Pictures of the system and its access let us plan the work in Blacknest before we set off.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
How to prepare
- Let us know about parking and loading
- Arrange a key holder or contact on site
- Have your last certificate or report to hand

Part by part
Grilles and diffusers
Grilles and diffusers that are designed to come out are removed for cleaning, then put back.
Extract ductwork
Extract fans pull air through these ducts, so a blocked duct strains them. A clean duct takes the load off.

Questions from Blacknest
Can ventilation in schools around Blacknest be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 9 schools and colleges on the FSA’s register within roughly a mile and a half of Blacknest, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Will you come out to Blacknest?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.
What happens if parts of the ductwork cannot be reached?
We list any unreached sections on the report, so it’s clear what’s outstanding. New access panels can be installed so the whole system can be cleaned.
Will we have paperwork to show the system was cleaned?
Yes. Every clean comes with a TR19® certificate and a photo report. BESA advises keeping certificates in the maintenance log.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Who is the responsible person?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What affects the cost of ventilation duct cleaning
The diagnosis comes before the price. The main factors are:
- Working hours and out-of-hours timing
- The number of sites or systems
- How big the system is
- A single visit or a regular plan
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or use the quote form for straight advice and a fixed quote.
