Surrey · Ductwork cleaning
Dorking ductwork cleaning
Ductwork cleaning across Dorking and nearby, timed so the site keeps working and finished with a written report and photos.
- Fat dripping from the ductwork
- Grease pooling at the foot of the riser
- A duct clean needed for an insurer
How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes a few hours for a short run, longer for long runs and tall risers. Send us pictures of the system and we can plan most of a visit in Dorking before we arrive.
- 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.
How to prepare
- Let us know when the site is closed or quiet
- Clear loose items from the work area
- Have your last certificate or report to hand
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Ductwork cleaning in Dorking
Each extract duct we take on in Dorking goes through the full routine: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and pictures complete the record. Common call-outs are for years of grease along the duct floor and grease pooling at the foot of the riser, across horizontal duct runs, attenuators and vertical risers.
Around a town like Dorking, extract cleaning usually means a restaurant, pub, takeaway or the kitchen of a school or care home. Each has a canopy, filters, ductwork and a fan to keep clear of grease, and each is cleaned to the same TR19® standard.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Honest limits
Ductwork cleaning cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Faulty fire dampers
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- A duct that’s too small or badly routed for the kitchen (a design issue)
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.
Parts of the system we cover
- Horizontal duct runs
- Multi-storey ducts
- Bends and junctions
- Attenuators
- Access panels
- Vertical risers
What the work involves, part by part
Horizontal duct runs
The underside of a horizontal duct collects the most grease. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
Attenuators and discharge
Attenuators, where fitted, quieten the extract, and their linings can soak up grease. They’re cleaned where possible and recorded if not.
Your questions about ductwork cleaning in Dorking
Can you clean school kitchen extracts in Dorking during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Dorking, it pays to plan holiday dates ahead. You can phone us on 0345 646 2711 or use the quote form with the dates the site is empty.
Who is the fire and rescue service for Dorking?
It’s Surrey Fire and Rescue Service, which covers Dorking. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How can I tell if my extract ducts are dirty?
Start with the date of the last clean. If it’s overdue, or there is not one, a clean is due, and grease readings will confirm how urgent it is.
How much does ductwork cleaning cost in Dorking?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Will the duct clean disrupt the kitchen?
Only while we’re working, and we work around you. Most kitchens book overnight or weekend cleans, so no service is lost.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
Do I get a certificate for ductwork cleaning?
You get a photo report with before and after pictures, plus a TR19 certificate when the whole system is cleaned. File them with the fire risk assessment.

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Ductwork cleaning in Dorking: the local picture
Food Standards Agency records list about 59 restaurants, cafés and canteens and about 10 sandwich bars and takeaways in and around Dorking, up to about a mile and a half out. Where they cook under a canopy, grease does not stop at the filters: it settles along the duct and up the riser. Kitchens in Dorking get their food hygiene inspections from Mole Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Surrey Fire and Rescue Service covers Dorking. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hospital like Headley Court, about 4.8 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a café or takeaway near Dorking Deepdene station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. School kitchens, at schools like St Paul's CofE (Aided) Primary School for example, are typically cleaned in the holidays so no lunches are lost.

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Why act early in Dorking
There’s no law that names TR19. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and grease in the duct is part of that. In a town like Dorking, a problem caught early is a planned visit, not an emergency.
