Ventilation duct cleaning for kitchens and businesses in Key's Green
When the work is finished, you get a TR19® certificate and before and after pictures. It shows what was cleaned, anything we couldn’t reach and when the system should next be inspected, so you have it all on record. If you have poor airflow from the vents and ducts that need a clean before handover, we can put it right.
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.

Key's Green questions
Can the work in Key's Green be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Key's Green can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in Key's Green be done out of term time?
Yes, out-of-term visits are normal for schools. Around Key's Green, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
What about areas you can’t get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
How often do ventilation ducts need cleaning?
TR19® Air is risk-based, so cleaning follows inspection rather than a fixed calendar. Each report recommends when the system should next be inspected.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Will you look at the ducts before quoting?
Yes. We always survey first, on site or from photos and drawings, and then quote a fixed price.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
What affects the quote in Key's Green
The diagnosis comes before the price. The main factors are:
- The scale of the work
- Whether several sites go on one quote
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
Asking for a quote
You don’t need the technical terms. Just send:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- Wide photos of the system and the area around it
For a fixed quote, phone us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes a weekend for a modest system, with large buildings phased floor by floor. If the van will struggle with a lane or gateway near Key's Green, let us know and we will plan around it.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
- Let us know when the site is closed or quiet
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Advice
Honest limits
In fairness, some problems need a different fix:
- Condensation caused by the building rather than the ducts
- Building management settings that run the plant
- Design problems with the ductwork layout
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly.
Parts of the system we cover
- General extract ductwork
- Grilles and diffusers
- Toilet extract systems
- Supply ductwork
- Hospitals and care homes
- Offices and schools
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Report leaks or damp near ceilings and risers
- Don’t run the ventilation while builders are sanding or cutting
- Stick to the filter change schedule
- Make sure nothing is stacked against extract grilles
We recommend when the system should next be inspected, based on what we found. Put it in the diary now so it isn’t missed.
Protect the system during building work by switching it off or covering the grilles.
What happens if it’s left?
After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. In a place like Key's Green, ductwork and fans are easy to forget until something goes wrong.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
