About our ductwork cleaning in Leatherhead
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. We are often asked to deal with proof of duct cleaning for the insurer and grease leaking from duct joints, across attenuators, horizontal duct runs and access panels.
In a town like Leatherhead, most of the kitchen extracts we’re asked about belong to restaurants, cafés, pubs, takeaways and school or care home kitchens. Whatever the kitchen, the canopy, filters, duct and fan all collect grease, and each is cleaned to the same TR19® standard.
We’ve been trading since 2009, as 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.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Different parts, different methods
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. We agree a sequence that suits the building, out of hours where possible.
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, which is one of the points we test.
Aftercare tips
Once we’ve finished, these simple steps help:
- Book the next clean before the recommended date
- Have the grease measured if cooking hours go up
- Don’t switch the extract off early
- Keep your cleaning records together
File the paperwork in the maintenance log. An insurer, fire officer or EHO may ask to see it, and the photos make the duct’s condition easy to see.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.

FAQs for Leatherhead
Can school kitchens in Leatherhead be cleaned in the holidays?
Yes. The holidays are the usual time for school work. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Leatherhead. Just phone us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Which environmental health team covers Leatherhead?
Food hygiene inspections in Leatherhead are carried out by Mole Valley council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What accreditations do you have?
Duct Doctor is 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 do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
What paperwork do you give after a duct clean?
A photo report, with readings and before and after photos, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we will quote them together.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a shift or more, depending on the length of the runs and the number of access points. Parking in a town like Leatherhead is typically straightforward, so the main questions are access and timing.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
How to prepare
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need

Advice
When something else is needed
In fairness, some problems need a different fix:
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that do not close (they need testing and remedials)
- Undersized or badly laid-out ducts
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly before booking.
What the work covers

What we’re called out for in Leatherhead
Risers carry the extract up through the building. Grease collects on the riser walls and gathers at the bottom as liquid grease runs down. Panels along the riser make proper cleaning possible.
These are the problems we see most often:
- High readings at a recent grease test
- Grease pooling at the foot of the riser
- Grease seeping out of the duct seams
- Hardened, baked-on grease in long horizontal runs
Commuter trade near Leatherhead station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
Questions to ask before you book
- Whether the work can be done while the site is closed
- Which accreditations they hold, and whether you can check them
- What happens if part of the system can’t be accessed
- Whether the whole system is included, or only the parts that are easy to reach
Leave it or put it right?
Grease left in a duct in Leatherhead hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. A fresh certificate on file is the best thing to have when someone asks to see your records.
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 give you a fixed price before we start.

Ductwork cleaning in Leatherhead: the local picture
Look up Leatherhead on the FSA’s food hygiene register and you will find about 53 restaurants, cafés and works canteens and about 19 takeaways and sandwich shops in and around Leatherhead, up to about a mile and a half out. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. In Leatherhead, food businesses are inspected by environmental health officers from Mole Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Leatherhead is Surrey Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you look after a school kitchen, at a school such as Leatherhead Trinity School and Children's Centre or anywhere near Leatherhead, the holidays are the usual time for a TR19® clean.
