Ductwork cleaning in Weston
Duct Doctor has cleaned kitchen extract ductwork since 2009, working across London and the South East. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers bends and junctions, attenuators and horizontal duct runs, and people most often call us about grease leaking from duct joints and readings above 200 microns from a grease thickness test.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Keeping the system healthy
After the visit, a few habits help the work last:
- Keep the fan on while anything is cooking
- Keep to the interval on the report
- File each certificate and photo report in the maintenance log
- Never cook with a filter missing
Any section of duct we couldn’t reach is listed on the report, with the reason. You can then decide whether to have access panels fitted.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
Weston: your questions answered
Can school kitchens in Weston be cleaned in the holidays?
Yes. The holidays are the usual time for school work. Around Weston, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we’ll fit the work in.
Is Weston within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Weston included. Let us know about access, parking and anything unusual about getting there when you book.
Are you insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
What about areas you cannot 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 long does it take to clean extract ducts?
Short runs are quick, but long or complex ducts may take several visits. We plan the work around your kitchen.
When to call us in Weston
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base, where it can pool. Panels along the riser make proper cleaning possible.
Most sites get in touch when they notice one of these:
- Fat dripping from the ductwork
- Ductwork that has never been cleaned
- Gaps where access panels were never fitted
- High readings at a recent grease test
Where a hall near Church of the Holy Trinity, or anywhere in Weston, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before booking anyone
- If they look at the system before pricing
- How VAT is shown on the quote
- When they can work, and whether that is outside your opening hours
- Whether the whole system is included, or only the parts that are easy to reach
Leave it or put it right?
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. A certificate that covers the ductwork is what they want to see. Planning a trip to Weston ahead is easier for everyone than a rushed one.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

Other services in Weston
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Ductwork cleaning in Weston: the local picture
Weston is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Weston are the job of North Hertfordshire council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.

What ductwork cleaning can’t fix
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- A duct that is too small or badly routed for the kitchen (a design issue)
- Parts of the duct with no way in
- A damper stuck open in the duct
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly.
What the work covers
- Attenuators
- Bends and junctions
- Multi-storey ducts
- Access panels
- Horizontal duct runs
- Vertical risers
What we do, step by step
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. Most of the time goes on the work itself, and that takes anything from a few hours to several visits, depending on the length of duct. Somewhere like Weston, lanes, gates and parking are worth mentioning in advance.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool

What the work involves, part by part
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, where fire dampers may be fitted. We test those as a separate job.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
