Ductwork cleaning for kitchens and businesses in Woodcock Hill
Not sure when the ductwork was last cleaned? Tell us about the system when you phone us on 0345 646 2711, or email photos, and a fixed price will follow, normally within one working day. Common call-outs are for thick crusts of old grease along the duct and heavy grease at the base of a riser, across bends and junctions, multi-storey ducts and attenuators.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Multi-site and managed buildings
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
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 to call us in Woodcock Hill
Grease in a duct running from a kitchen in Woodcock Hill is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Keep an eye out for any of the following:
- Proof of duct cleaning for the insurer
- Grease seeping out of the duct seams
- A rancid smell from the extract duct
- Thick deposits at the bottom of a vertical duct
Volunteers running a hall kitchen near Church of St Mary, or anywhere in Woodcock Hill, may not know when the extract was last cleaned, and a grease test settles it.

What the work involves, part by part
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and test it before and after.
Horizontal duct runs
A long flat run can’t be cleaned from one end. Where the gaps between panels are too long, we record what couldn’t be reached and can fit extra panels.
Questions from Woodcock Hill
Do you work overnight in Woodcock Hill?
Yes, we can come after you close and finish before you open. It means the site in Woodcock Hill keeps running as normal. Let us know the hours you are closed and we will book within them.
Who would carry out a food hygiene inspection at a kitchen in Woodcock Hill?
In Woodcock Hill, it’s Three Rivers council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can extra access doors be added to the duct?
Yes, we fit access panels where the duct needs them. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
Can you set up regular visits?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Do I get a certificate for ductwork cleaning?
A photo report, with readings and before and after photos, plus a TR19 certificate for a full system clean. It also gives a recommended next clean date.
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. Work is timed around how each site runs.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
How long does it take to clean extract ducts?
It depends on the length of the duct, the number of access panels and how much grease there is. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.
What happens if it’s left?
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. Rural sites can’t always move to another kitchen or room when something fails.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Woodcock Hill kitchens: local notes
The FSA’s data shows about 16 pubs and bars and about 3 hotels, B&Bs and guest houses registered in Woodcock Hill and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Environmental health officers from Three Rivers council inspect food businesses in Woodcock Hill. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Woodcock Hill is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens, like those at hospitals such as Bishops Wood Hospital (about 1 mile south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like St Mary's Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes a shift or more, depending on the length of the runs and the number of access points. A quick note on how to find the site and where to park makes a visit to Woodcock Hill run smoothly.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
- Have your last certificate or report to hand
