Canopy cleaning in Theydon Bois
Duct Doctor has cleaned canopies and hoods since 2009. As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, we treat the canopy as one part of a whole system, and we are fully insured, with CHAS, SafeContractor and ISO 9001. Typical jobs include drips from the canopy onto the range and a plenum thick with grease behind the filters, on plenum chambers, island canopies and baffle filters.
For a smaller kitchen near Theydon Bois, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

Grease, kitchens and Theydon Bois
Food Standards Agency data counts about 7 cafés, restaurants and staff canteens in Theydon Bois and the streets around it, up to about 1.5 miles out. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. Kitchens in Theydon Bois get their food hygiene inspections from Epping Forest council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Theydon Bois is covered by Essex County Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as Theydon Bois Primary School or anywhere near Theydon Bois, the holidays are the usual time for a TR19® clean. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St. Margaret's Hospital is the nearest hospital to Theydon Bois, about 2.5 miles north-east. If you run catering at a historic house or estate in the area (Hill Hall is about 2.3 miles east), event kitchens in older buildings often have awkward duct runs that need planning.

Different parts, different methods
Plenums and filter housings
Filter housings hold the filters in place, and their channels fill with grease. We clean them so the filters sit tight and leave no gaps.
Grease troughs and gutters
Many canopies have troughs or gutters around the edge to catch running grease. We empty and degrease them, so they can do their job again.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A canopy too small for the cooking under it (that’s a design question)
- Grease filters too damaged to refit (they need replacing)
- A fan that cannot pull enough air because it’s worn out
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think before you book.
What the work covers
- Baffle filters
- Canopy light fittings
- Island canopies
- Grease gutters
- Wall canopies
- Plenum chambers
Between visits
Here’s the after-treatment advice, in brief:
- Clean the baffle filters often
- Report new drips or smells from the canopy
- Clean the hood’s outer surfaces daily
- Check and empty canopy gutters regularly
We recommend when the canopy, or the whole system, should next be cleaned. That date is based on your cooking hours and what we found, in line with BESA guidance.
Keep the fan running throughout service and for a short while after. Air that keeps moving carries less grease onto the canopy.
Common questions in Theydon Bois
Can you get to a site in Theydon Bois?
Yes, Theydon Bois is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Who is the fire and rescue service for Theydon Bois?
Fire safety enforcement in Theydon Bois is handled by Essex County Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Is the inside of the hood cleaned?
We clean the canopy inside and out, along with its seams and grease channels. The plenum and filter housing behind the filters are cleaned too.
Do we need to close the kitchen for a canopy clean?
We clean when the kitchen is closed: after service, overnight or before opening. Equipment under the canopy needs to be off and cool.
How long is a canopy clean?
A single canopy with a light build-up is fairly quick, while long canopies, several hoods or heavy deposits take more time. You will know before any work starts.
What kinds of canopies do you clean?
Wall and island canopies, long cooking-line hoods and small single hoods. The method is the same: filters out, plenum and housing cleaned, canopy degreased inside and out.
Can I just have the canopy cleaned instead of the whole system?
You can have the canopy cleaned on its own, but it won’t cover the ductwork or fan. For TR19, the whole system needs cleaning, at intervals set by BESA guidance.
What we do, step by step
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the canopy cleaning, tidy up and leave you the report. On site, the work takes a few hours for most canopies. Tell us about any gates, ladders or locked plant areas at your site near Theydon Bois when you book.
- The canopy is checked from photos or on a visit.
- Once the kitchen has closed, the cooking line is cooled and sheeted.
- With the filters removed, the plenum and filter channels are cleaned.
- The canopy shell, seams, troughs and gutters are degreased inside and out.
- Filters are refitted, the area cleaned down and the photo report put together.
Getting ready for the visit

Related advice
Leave it or put it right?
Grease dripping from the hood can fall onto food, pans and worktops. That is a hygiene problem as well as a fire one, and environmental health officers look at the cleanliness of equipment, extraction included.
