Ventilation duct cleaning in Cranbrook, Kent
Ventilation duct cleaning in Cranbrook, surveyed first and signed off with a written report and photos. Ask us for a fixed quote.
- Ducts that need a clean before handover
- Poor airflow from the vents
- Ventilation that needs a TR19® Air inspection
Aftercare tips
After the visit, a few habits help the work last:
- Make sure nothing is stacked against extract grilles
- Get leaks near ductwork fixed quickly
- Protect the system from construction dust
- Keep grilles and diffusers dusted
The report includes a recommended date for the next inspection, in line with the risk-based approach of TR19® Air. Diary it right away so it doesn’t slip.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.
How we handle ventilation duct cleaning in Cranbrook
Dust in ventilation ductwork is not only a cleanliness issue. It can restrict airflow, make the system work harder and send dust back into occupied rooms. Cleaning restores the clear airway the system was designed with. We’re often asked to deal with duct runs that can’t be reached for cleaning and supply ducts with years of dust inside, on hospitals and care homes, grilles and diffusers and supply ductwork.
In a smaller place like Cranbrook, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
The paperwork matters as much as the work. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What we are called out for in Cranbrook
Building work is one of the biggest sources of debris in ducts, particularly if it’s left running while work goes on. Plaster, wood and masonry dust can sit in the ducts for years.
Signs it’s time to call us include:
- Ducts that need a clean before handover
- Dust marks around grilles and ceiling diffusers
- Odours carried round the building by the ducts
- Ductwork with too few access panels to clean
Healthcare ventilation, from large hospitals like Benenden Hospital (about 3.6 miles east) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- Whether they’re fully insured
- Whether the price is fixed
- Whether the quote shows VAT
- What paperwork you get at the end
Leave it or put it right?
Leave dust in the ductwork and it keeps building. Every year adds to the job, and the more gets blown back into the rooms. It’s better to plan the work at a site near Cranbrook than wait for a failure.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Your questions about ventilation duct cleaning in Cranbrook
Will you come out to Cranbrook?
Yes, Cranbrook is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can ventilation in schools around Cranbrook be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Cranbrook. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. A fixed quote follows.
How often should ventilation ductwork be cleaned?
TR19® Air is risk-based, so cleaning follows inspection rather than a fixed calendar. Each report recommends when the system should next be inspected.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Is TR19 a legal requirement?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What ventilation duct cleaning looks like in Cranbrook
Food Standards Agency records list about 4 schools, colleges and universities and about 3 care, childcare and hospital premises registered as food businesses across Cranbrook and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Cranbrook is Benenden Hospital, about 3.6 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from one overnight visit to a phased programme over several weeks. For a place like Cranbrook, 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, pictures or a site visit.
- Ducts are inspected at access points and the condition recorded.
- The area below is protected and the system switched off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Agree a time when the area can be out of use
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Managing agents and facilities teams in Cranbrook
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
