Ductwork cleaning in Tisman's Common, done properly
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, and our certificates are issued through the BESCA Vent Hygiene Elite portal. Typical jobs include grease leaking from duct joints and high readings at a recent grease test, across horizontal duct runs, multi-storey ducts and attenuators.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What we’re called out for in Tisman's Common
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped, and build-up speeds up.
What we’re most often called out for:
- Readings above 200 microns from a grease thickness test
- A rancid smell from the extract duct
- Gaps where access panels were never fitted
- Grease seeping out of the duct seams
Bursars and site managers at schools such as Pennthorpe School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- What’s included in the scope, part by part
- Whether the price is fixed
- Whether a survey comes first
- Whether a written report and pictures are included
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. The timing of a visit to Tisman's Common is set by you, and the travel is our side of the planning.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
How to prepare
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Every quote begins with a look at the system, 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 so you know the cost before any work starts.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Keep your cleaning records together
- Keep access panels clear of stored items
- Report any grease dripping from duct joints
- Keep grease filters clean and fitted whenever you cook
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Grease and dirty water are contained and removed.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Tisman's Common and across West Sussex. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

What happens if it’s left?
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Leaving the duct makes those limits harder to keep to. A fault that closes a site in a village like Tisman's Common affects everyone who depends on it.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.

Tisman's Common questions
Which fire service covers Tisman's Common?
Tisman's Common is in the area of West Sussex Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Which council inspects kitchens in Tisman's Common?
The local authority for Tisman's Common is Horsham council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
How much does ductwork cleaning cost in Tisman's Common?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Can you clean ductwork with no access panels?
Every reachable section is cleaned and the rest recorded. Extra panels can be installed, and we can do that for you.
What shows that the ducts need a clean?
Start with the date of the last clean. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What affects the cost of ductwork cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Any permits to work or inductions
- How easy every part is to reach
- The condition we find in the survey
- Working hours and out-of-hours timing
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
What to send for a quote
Before you ask for a quote, gather:
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
- The paperwork from the last visit, if you have it
- The site address and the type of premises
If you need ductwork cleaning in Tisman's Common, phone us on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. We typically send a fixed quote within one working day.
When it’s something else
We will not sell you work that does not address the problem, so here are the limits:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Faulty fire dampers
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly before you book.
