How we handle canopy cleaning in Dorchester
Duct Doctor has cleaned canopies and hoods since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. The work covers grease gutters, wall canopies and island canopies, and the jobs we see most are a hood coated in old grease and grease channels that no longer drain.
Somewhere as small as Dorchester, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Clean the baffle filters often
- Keep the fan on through service
- Make sure filters sit tight in the housing
- Do not scrape the canopy with metal tools
Where the canopy is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. If the job covers only the canopy, the paperwork reflects that.
Run the extract for as long as anything is cooking. Air that keeps moving carries less grease onto the canopy.
How the job changes from site to site
Grease troughs and gutters
Some troughs drain to a cup or drawer, that’s emptied and cleaned too, and we’ll show staff where it is.
Pub and hotel kitchens
In pubs and hotels, the kitchen may be busy for much of the day. That’s a lot of grease on the canopy, and canopy cleans between full cleans can help.
What affects the quote in Dorchester
The survey tells us what the work involves. The main factors are:
- The size of the system
- The times the site is available
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any access panels or hatches you can see
- A few general shots of the system
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
For a fixed quote, call 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
Dorchester questions
Can you work in Dorchester outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you cover smaller places like Dorchester?
Yes, we work in villages as well as towns, and Dorchester is covered. Let us know about access, parking and anything unusual about getting there when you book.
Does a canopy clean meet TR19?
Canopy cleaning is part of TR19, not the whole of it. Your report lists exactly what was cleaned, so your records stay accurate.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Which kinds of sites do you work on?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
What does canopy cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
How long does canopy cleaning take?
That depends on the size of the canopy and how much grease is on it. Typically it takes an hour or two for one small canopy, longer where there are several.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
What happens if it’s left?
For a kitchen in Dorchester, a canopy that looks greasy can colour a whole inspection. A clean hood is a sign the kitchen is cared for and keeping it that way is easier than catching up. In a place like Dorchester, ductwork and fans are easy to forget until something goes wrong.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

When to call us in Dorchester
A canopy with gaps around its filters lets grease straight through. The plenum and housing behind them then take far more grease than they should, which shows up as heavy deposits when the filters come out.
Signs it’s time to call us include:
- A canopy that no longer draws the smoke away
- An EHO comment about the canopy
- A hood coated in old grease
- A plenum thick with grease behind the filters
Bursars and site managers at schools such as Dorchester St Birinus Church of England School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- What records you will receive afterwards
- How VAT is shown on the quote
- What insurance they carry
How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes an hour or two for one small canopy, longer where there are several, and we clear up before we go. Seeing the system in pictures first means the trip to Dorchester can be planned properly.
- Diagnosis first: we look behind the filters as well as at the hood.
- We protect everything below once it has cooled.
- Heavy deposits come off by hand, then the surfaces are degreased.
- We finish the plenum, troughs and canopy and check them over.
- The canopy is signed off with before and after pictures and a next clean date.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
Get a fixed 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, before any work starts.

Grease, kitchens and Dorchester
Dorchester sits within the area of Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. At about 47 miles from central London, Dorchester sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
If you run a church or community hall kitchen, near Dorchester Abbey or elsewhere in Dorchester, its extract still collects grease from every lunch and event. A hospital like Littlemore Hospital, about 5.6 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Dorchester is about 4 miles north-east of Didcot, in Oxfordshire. Whatever kind of site you run in Dorchester, canopy cleaning is something we can help with.
