Ductwork cleaning in Frensham
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. If you are dealing with gaps where access panels were never fitted and duct runs with no cleaning record, we can put it right.
For a kitchen in or near Frensham, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Why deal with it now?
Grease left in a duct in Frensham hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. Planning a trip to Frensham ahead is easier for everyone than a rushed one.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

What else we do in Frensham
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a few hours for a short run, longer for long runs and tall risers. Seeing the system in pictures first means the trip to Frensham can be planned properly.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- 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.
- We close up, re-test, photograph and record anything out of reach.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.
Advice
What we are called out for in Frensham
Risers carry the extract up through the building. Grease clings to the walls and can run down to the base, where it can pool. Panels along the riser make proper cleaning possible.
The symptoms we are asked about most are:
- Readings above 200 microns from a grease thickness test
- Grease pooling at the foot of the riser
- Ductwork that has never been cleaned
- Years of grease along the duct floor
Church and community hall kitchens, near Church of St Mary the Virgin or anywhere around Frensham, are easy to forget, but their extracts collect grease like any other.

FAQs for Frensham
Can you clean school kitchen extracts in Frensham during the holidays?
Yes, holiday work suits schools best. Around Frensham, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
Which environmental health team covers Frensham?
Food hygiene inspections in Frensham are carried out by Waverley council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
How long does it take to clean extract ducts?
It takes from a few hours to more than one visit, depending on duct length and access. The survey tells us how long your duct needs.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
How is kitchen extract ductwork cleaned?
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.
How often does extract ductwork need cleaning?
The duct is cleaned as part of the whole system, at intervals set by BESA guidance, from every 3 months for heavy use to every 12 months for light use. Grease thickness testing shows whether that’s often enough.
Do we have to stop cooking while the ducts are cleaned?
We plan the clean when you are not cooking. Overnight and weekend work is common, so no service is lost.

How the job changes from site to site
Access panels
Extra panels can be installed where there are gaps, so the next clean reaches more of the system. The survey shows where they’re needed.
Vertical risers
Risers carry the extract up through the building to the roof. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Do not block access panels with shelving or stock
- Store the certificate with the fire risk assessment
- Keep to the interval on the report
- Do not switch the extract off early
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.
Have access panels fitted where sections cannot be reached. It does not stop grease forming, but it stops it building unseen.
What your team can do, and what needs us
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.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
What ductwork cleaning looks like in Frensham
There are about 4 restaurants, cafés and canteens in and around Frensham, up to about a mile and a half out, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Food hygiene inspections in Frensham are the job of Waverley council’s environmental health team. 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. Frensham is covered by Surrey Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run catering at a healthcare site, such as a hospital like Chase Community Hospital about 5.1 miles south-west, the extract may need cleaning more often than a part-time kitchen. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Farnham Castle is about 3.6 miles north), access may need planning.
