Kitchen duct cleaning in Knapp
Across Knapp, we clean kitchen extract systems to BESA TR19® Grease. The job starts with a survey and grease readings, then works through canopy, plenum, filters, ductwork, fan and discharge. You get a TR19 certificate and a photo report at the end. The work covers canopies and hoods, discharge points and plenums and filters, and the jobs we see most are rancid smells from grease in the duct and a kitchen with no current TR19 certificate. When a restaurant in Knapp asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that’s our main job: canopy to fan, to TR19® Grease.
Grease that collects out of sight, behind the filters and along the duct, is what insurers and fire officers worry about, which is why a TR19® clean in Knapp goes well beyond the canopy.
In a small place like Knapp, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
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. Any parts we couldn’t reach are recorded on it too.

Questions from Knapp
Do you cover smaller places like Knapp?
Yes, we work in villages as well as towns, and Knapp is covered. Photos of the system and directions to the site help us plan the visit.
Do you do school kitchen extract cleaning in Knapp in the summer holidays?
Yes, holiday work suits schools best. Around Knapp, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711, or email photos with the dates the site is empty.
Why do insurers care about extract cleaning?
Grease in an extract is a known fire risk, so many insurers want evidence it’s being cleaned to TR19. Our certificate and photo report give you that evidence.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Is a quote from pictures possible?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Give the canopy a daily wipe
- Refit filters properly after cleaning
- Keep to the recommended cleaning interval
- Keep the baffle filters clean
You leave with a date for the next clean, set from your daily cooking hours and the readings we took. We can put the system on a 3, 6 or 12-monthly plan, so the date is not missed.
Keep the outside of the canopy wiped and any grease cups emptied. It won’t replace a TR19 clean, but it slows what reaches the duct.

How the job changes from site to site
Restaurant and pub kitchens
Busy restaurant and pub kitchens often cook for long hours, frying and grilling, so their cleaning interval is often 3 or 6 months under BESA guidance. Cleans are done after close, overnight or before opening.
Ductwork and risers
Risers take the extract up through floors to roof level, and grease often collects at the bottom of them. They’re cleaned through access points along their height.
What happens if it’s left?
Putting it off simply moves the grease further down the duct. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Regular cleans keep each visit shorter. Somewhere as small as Knapp, losing a kitchen or building to a fault is felt by everyone who uses it.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
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.
Honest limits
We’d rather tell you now than book work that won’t help, so here are the limits:
- Ductwork that is corroded, split or leaking (that is for a ductwork contractor)
- Extraction that can’t cope with the cooking because of its design
- Fire dampers that won’t close (that needs damper testing and remedials)
If in doubt, give us a ring on 0345 646 2711, or email photos and we will say what we think.
Parts of the system we cover
- Horizontal duct runs
- Vertical risers
- Canopies and hoods
- Plenums and filters
- Discharge points
- Extract fans
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. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
What happens on the day
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. We agree a date with you, plan the drive to Knapp and turn up when the site is quiet.
- First the diagnosis: a survey of the whole system and its access points.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
Getting a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
