About our canopy cleaning in Knowl Hill
Duct Doctor has cleaned canopies and hoods since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001. If you’re dealing with greasy streaks across the canopy and a greasy hood noticed by an inspector, we can put it right, from canopy light fittings, baffle filters and plenum chambers onwards.
Work in a small place like Knowl Hill starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
We have 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.

Knowl Hill questions
Who is the fire and rescue service for Knowl Hill?
That is Royal Berkshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can the work in Knowl Hill be done at night or at weekends?
Yes, we can come after you close and finish before you open. That way a site in Knowl Hill does not have to lose a day’s trading. Just phone us on 0345 646 2711 or email us with your opening times and we will plan around them.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
How much of the canopy do you clean?
Inside and out, along with its seams and grease channels. With the filters out, the plenum and housing are cleaned as well.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Will I get a report after the canopy clean?
A photo report shows the canopy and plenum before and after. Full system cleans also come with a TR19 certificate.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a few hours, depending on the size of the canopy and how much grease has built up. Visits to a village like Knowl Hill are booked in advance, at a time that suits whoever runs the site.
- We start by checking the canopy, filters and plenum.
- The range is turned off and allowed to cool before we cover it.
- Filters come out and the plenum behind them is scraped and degreased.
- We degrease the canopy shell, its seams and the grease troughs.
- Filters go back, the area is cleaned down and pictures are taken.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area
Get a fixed quote
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Fixed quotes for canopy cleaning in Knowl Hill
Sites vary more than people expect. What affects the quote:
- Working hours and out-of-hours timing
- A single visit or a regular plan
- Where the site is and how we reach it
- Whether several sites go on one quote
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
What we need to know
Before you ask for a quote, gather:
- Any access panels or hatches you can see
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
If you need canopy cleaning in Knowl Hill, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote usually follows within one working day.
Common problems we fix in Knowl Hill
Air straight off the range hits the canopy first. Fat in that air settles on the inside of the hood, in its seams and on the filters before what gets through reaches the plenum.
Signs it’s time to call us include:
- Grease filters blocking between washes
- A hood coated in old grease
- A canopy that no longer draws the smoke away
- A canopy flagged at an environmental health inspection
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Knowl Hill is St Mark's Hospital, about 3.3 miles east.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Run the extract the whole time you’re cooking
- Avoid harsh scourers that scratch the canopy
- Wash or exchange the filters on a regular cycle
- Keep every filter in place while cooking
Keep the photo report with your maintenance log, so it’s ready when an EHO, insurer or fire officer asks. Photos of a clean canopy and plenum make the record easy to follow.
Empty the grease troughs and cups before they fill. Most canopy drips start with a full trough, so make emptying them part of the closing routine.
Leave it or put it right?
If the canopy waits for the next full clean, grease keeps adding up. Some kitchens need the canopy cleaning more often than the whole system, and readings or a look behind the filters will show it. Our emergency line runs 24/7, but a planned visit to Knowl Hill is calmer for everyone.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
