Ventilation duct cleaning in New Barn
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. Common call-outs are for stuffy rooms and stale air and ductwork with too few access panels to clean, on supply ductwork, offices and schools and general extract ductwork.
Around a place like New Barn, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Busy, occupied buildings like these are where clean supply air matters most. About 20 miles out from central London, New Barn is part of the South East area we work across.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Ducts that are damaged, corroded or leaking and need replacing
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Design problems with the ductwork layout
Not sure which it is? You can call us on 0345 646 2711 or email us and we will tell you honestly before booking.

What else we do in New Barn
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Get leaks near ductwork fixed quickly
- Keep to the inspection interval in your report
- Keep grilles and diffusers dusted
- Keep filters changed on time
What was cleaned is listed, along with any parts that weren’t accessible, with photos before and after. If access panels are needed, we’ll say where.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.
When to call us in New Barn
Ventilation hygiene often gets left out of planned maintenance. A building in New Barn can have well-serviced plant and dirty ductwork at the same time.
The symptoms we’re asked about most are:
- Musty smells from the ventilation
- Ductwork never cleaned since it was installed
- Duct runs that cannot be reached for cleaning
- Toilet and washroom extracts full of fluff
Healthcare ventilation, from large hospitals like Gravesham Community Hospital (about 3.6 miles north-east) to small clinics, depends on clean filters, coils and ducts.
Before you book anyone
- What insurance they carry
- Whether inaccessible sections are listed on the report
- What records you will receive afterwards
- Whether the quote shows VAT
What affects the cost of ventilation duct cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- Working hours and out-of-hours timing
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.
Asking for a quote
There’s no need for technical detail. Just send:
- Any previous report or certificate
- Problems your staff have spotted
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then ring 0345 646 2711, or send details by email.
Different parts, different methods
Offices and retail
Fit-outs in offices and shops leave dust in the ventilation. Cleaning before the new occupants move in makes sense.
Grilles and diffusers
Where they come out, grilles are taken down and cleaned, then put back.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes from one overnight visit to a phased programme over several weeks. For a place like New Barn, we load the van from the survey notes so the work can be done in one visit where possible.
- We survey the system from drawings, photos or a site visit.
- Ducts are inspected at access points and the condition recorded.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Questions from New Barn
Can you come to New Barn after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
Can you get to a site in New Barn?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you clean grilles and diffusers?
Yes. Removable grilles come down for cleaning and go back up. Fixed ones are cleaned in place.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
