Signs you need ventilation duct cleaning in Seal
Many systems run for long hours, day after day, and every hour of running brings more dust with it. The busier the building, the faster it builds up.
Common reasons sites call us include:
- Grilles and diffusers streaked with dirt
- Dusty supply ductwork that hasn’t been cleaned in years
- Stuffy rooms and stale air
- Musty smells from the ventilation
Sevenoaks Hospital, about 1.1 miles west, is the nearest hospital to Seal, and healthcare sites of every size need their supply air kept clean.

How we handle ventilation duct cleaning in Seal
Ductwork is reached through access panels at intervals along the system. Where there are not enough panels to reach every section, we note the uncleaned parts in the report, and new access panels can be installed for the next clean. The work covers toilet extract systems, general extract ductwork and hospitals and care homes, and common reasons people get in touch are supply ducts with years of dust inside and musty smells from the ventilation.
Work in a small place like Seal starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Leave it or put it right?
Dust in ducts doesn’t go away on its own. Every year adds to the job, and the more gets blown back into the rooms. A planned visit to Seal is easier to arrange than an emergency callout.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.

What the work involves, part by part
Hospitals and care homes
Dust control matters during work in occupied care settings. The area is protected, and debris contained and removed.
Extract ductwork
General extract ductwork removes stale air from rooms, toilets and washrooms. Lint, dust and fibres gather inside and restrict the flow over time.
Common questions in Seal
Can you work in Seal outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Seal can fit around your hours. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Will you come out to Seal?
Yes. Villages and rural sites across the South East are part of our work, Seal included. The journey is planned ahead, so a few details about the route help.
Do you survey the system first?
Yes. We always survey first, on site or from photos and drawings, and then quote a fixed price.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How often should ventilation ductwork be cleaned?
That varies with the building, the filters and how hard the system works. Regular inspection tells you when it’s due.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you survey before quoting?
Yes. We always survey first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Is TR19 a legal requirement?
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.

- Ventilation that’s undersized for the building
- Cooking extract ducts, which are a separate specialist clean
- Leaks from roofs, pipes or walls into the ductwork
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
Parts of the system we cover
- Toilet extract systems
- General extract ductwork
- Grilles and diffusers
- Hospitals and care homes
- Supply ductwork
- Offices and schools
How it works
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. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from one overnight visit to a phased programme over several weeks. Seeing the system in pictures first means the trip to Seal can be planned properly.
- We look at the system and any earlier reports.
- Inspection points are chosen and the ducts examined.
- 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.
Before we arrive
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time
- Clear the space around the work

Advice
Ventilation in Seal buildings
Food Standards Agency data includes about 15 schools, colleges and universities and about 4 care, childcare and hospital premises within about 1.5 miles of central Seal. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Seal, about 20 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. Sevenoaks Hospital is the nearest hospital, about 1.1 miles west of Seal. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
School buildings such as Seal Church of England Voluntary Controlled Primary School are usually done in the holidays, so classrooms are not disturbed.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What affects the quote in Seal
The survey tells us what the work involves. We look at:
- Whether it’s a one-off visit or part of a schedule
- The size of the system
- How easy every part is to reach
- Any permits to work or inductions
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Your opening hours and when the area is out of use
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.
