Ductwork cleaning for kitchens and businesses in Knaphill
No two duct runs are the same, in Knaphill or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route, so we know where to get in and how long it will take. The work covers horizontal duct runs, attenuators and vertical risers, and people most often call us about thick deposits at the bottom of a vertical duct and fat dripping from the ductwork.
In a smaller place like Knaphill, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Ductwork cleaning around Knaphill
The FSA’s food hygiene register includes about 7 pubs, bars and clubs within roughly a mile and a half of the centre of Knaphill. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Knaphill get their food hygiene inspections from Woking council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Knaphill sits within the area of Surrey 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.
School kitchens, at schools like Knaphill School for example, are usually cleaned in the holidays so no lunches are lost. If you run catering at a healthcare site, such as a hospital like Brookwood Hospital about under half a mile south, the extract may need cleaning more often than a part-time kitchen.

What we do, step by step
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the ductwork cleaning, tidy up and hand over the paperwork. The visit itself takes a few hours for a short run, longer for long runs and tall risers. Evenings, weekends or a closed day all work for a site in a place like Knaphill.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, photos and a recommended next clean date complete the job.
How to prepare
- Find the previous report, if there is one
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
Advice
What we’re called out for in Knaphill
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
The symptoms we’re asked about most include:
- Readings above 200 microns from a grease thickness test
- A rancid smell from the extract duct
- Proof of duct cleaning for the insurer
- Thick deposits at the bottom of a vertical duct
If you run a church or community hall kitchen, near St Hugh of Lincoln's Church or elsewhere in Knaphill, its extract still collects grease from every lunch and event.
What to look for in a quote
- How areas they cannot reach will be recorded
- What’s included in the scope, part by part
- Whether the quote is based on a survey or photos
- Whether the work can be done while the site is closed
What affects the quote in Knaphill
We quote each job individually. These are the things that affect it:
- Whether we need access equipment or extra panels

- Travel, parking and unloading
- One-off work versus a regular cycle
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see

Aftercare tips
After the visit, a few habits help the work last:
- Keep access panels clear of stored items
- Never cook with a filter missing
- Get panels fitted where the duct couldn’t be cleaned
- Ask for a grease thickness test if the kitchen gets busier
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Knaphill questions
Which fire service covers Knaphill?
That’s Surrey Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who inspects food businesses in Knaphill?
In Knaphill, it’s Woking council that carries out food hygiene inspections. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
How often does extract ductwork need cleaning?
At least as often as BESA guidance sets for your cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What shows that the ducts need a clean?
The date on the last certificate is the first thing to check. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Leave it or put it right?
Old grease in a duct for a kitchen in Knaphill does not stay soft. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Even a site near Knaphill that is only busy part of the week needs its system checked on a schedule.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or drop us a line, and we will talk you through it.
