Why it’s worth doing now in Marden Thorn
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. It’s worth booking a check, because nobody sees inside a duct day to day.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Why Marden Thorn businesses choose us
- Out-of-hours work and a 24/7 emergency line
- Full insurance on every job
- We diagnose before we treat
- Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease

TR19 inspection in Marden Thorn, done properly
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you are on. The work covers wet film thickness tests, insurer audits and pre-clean surveys, and common reasons people get in touch are ductwork where grease may be over the TR19 limits and kitchen extract systems with no recent grease readings.
In a village or hamlet like Marden Thorn, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
Good records are part of the job. You get a written report with pictures after each 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 ready for an insurer, fire officer or EHO.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
TR19 inspection in Marden Thorn: the local picture
The Food Standards Agency lists about 4 pubs and bars as registered food businesses within about 1.5 miles of central Marden Thorn. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Environmental health officers from Maidstone council inspect food businesses in Marden Thorn. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Marden Thorn sits within the area of Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A TR19® clean in Marden Thorn doesn’t stop at the filters: the plenum, ductwork, fan and discharge are cleaned too.

What else we do in Marden Thorn
Part by part
Vertical risers
Risers carry the extract up through the building. Grease can run down and collect at the base, so we check there.
Canopy and plenum
Clean-looking filters do not mean a clean plenum. So we measure behind the filters, not just in front.
What affects the quote in Marden Thorn
A fixed price needs a few facts first. We check:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- The times the site is available
- How easy every part is to reach
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.
Helping us quote
To speed up the quote, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
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 photos, get a survey first. Either way, you get a fixed price before we start.
The process
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a couple of hours for a typical kitchen extract system. Seeing the system in pictures first means the trip to Marden Thorn can be planned properly.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or email us.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Store grease readings where your insurer can see them
- Report grease dripping from the canopy
- Mention new equipment or longer hours at the next test
- Keep the route to access panels clear
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
Marden Thorn: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Marden Thorn?
Kitchens in Marden Thorn are inspected by Maidstone council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which fire authority looks after Marden Thorn?
Fire safety enforcement in Marden Thorn is handled by Kent Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
At what point does grease need cleaning?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. Our report sets your readings against both.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Will you produce a report for our insurer?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
Is a quote from pictures possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What if parts of the system can’t be reached?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711 or email us.
When to call us in Marden Thorn
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
The symptoms we’re asked about most include:
- Surveys needed before quoting a full clean
- Insurance renewals needing proof of TR19 cleaning
- Kitchens taken over with no cleaning records
- Sections of duct that can’t be reached
Before-and-after photos and a TR19® certificate come with every clean around Marden Thorn.
