Kitchen extract cleaning in Waterdale, done properly
Duct Doctor has been cleaning kitchen extract systems since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. The work covers vertical risers, horizontal duct runs and plenums and filters, and the jobs we see most are extraction mentioned at an environmental health visit and a TR19 certificate needed for the insurer. Extraction cleaning, hood cleaning and TR19 duct cleaning all end up in the same place: a system that’s clean inside, not just on the surface, and a certificate that proves it.
Kitchens that fry and grill hardest need the most frequent cleans, so we look at the menu as well as the opening hours when we suggest the next date.
Work in a small place like Waterdale starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Kitchen extracts in Waterdale
There are about 27 restaurants, cafés and works canteens and about 17 sandwich bars and takeaways in Waterdale and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Each one that cooks under a canopy has an extract system that collects grease and needs regular cleaning. Environmental health officers from Three Rivers council inspect food businesses in Waterdale. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Waterdale is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you run catering at a historic house or estate in the area (High Elms Manor is about 0.5 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in Waterdale, still needs its extract cleaned, just less often.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes as long as the system needs, from a few hours to several planned visits. A few photos of the system help us make the most of a visit to a place like Waterdale.
- First comes a survey of the whole system, by photos or a visit.
- Set points are tested for grease thickness and the quote is fixed before work begins.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Readings and pictures are taken again, and you receive a TR19 certificate and photo report.
Before we arrive
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
- Mention any locked doors, roof access or ceiling voids

What else we do in Waterdale
Leave it or put it right?
If your kitchen in Waterdale is past its cleaning date, it’s worth booking now. It takes anything from a few hours to a full night, depending on the size of the system, and we fit around your opening hours. Every extra month adds grease. Equipment tucked in a roof space or outbuilding near Waterdale rarely gets looked at unless someone books it.
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

When it’s something else
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- A duct that is holed or coming apart
- Fire dampers that will not close (that needs damper testing and remedials)
- Extraction that cannot cope with the cooking because of its design
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly before booking.
Where we work
- Plenums and filters
- Canopies and hoods
- Horizontal duct runs
- Extract fans
- Discharge points
- Vertical risers
Aftercare tips
So the system stays in good health:
- File each certificate with the fire risk assessment
- Book the next clean before the date on the report
- Switch the fan on before cooking starts
- Do not let the canopy gutters overflow
The report gives a recommended date for the next clean, based on your cooking hours and the grease we measured. We can put the system on a 3, 6 or 12-monthly plan, so the date isn’t missed.
Clean the grease filters often, not just on clean day. A filter that’s clean and seated properly stops more grease getting into the plenum, which slows build-up further down the system.
Waterdale: your questions answered
Who enforces fire safety at workplaces in Waterdale?
It’s Hertfordshire Fire and Rescue Service, which covers Waterdale. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who would carry out a food hygiene inspection at a kitchen in Waterdale?
In Waterdale, 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.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Do I have to clean my extract to TR19 by law?
Strictly, the legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, not from TR19. In practice, TR19 is how kitchens show they’re managing grease, and an insurer may refuse or reduce a claim without it.
Are you a BESCA Vent Hygiene Elite member?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we are fully insured.
What’s the right cleaning interval for a kitchen extract?
That comes down mainly to daily cooking hours. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. We will recommend a date after measuring the grease.
Common problems we fix in Waterdale
How fast grease builds up depends mostly on how long the kitchen cooks each day. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. They are minimums: measured grease levels set the real interval.
Any of these means the system needs a check-up:
- Ductwork thick with old, hardened grease
- Stale cooking odours from the system
- Missing paperwork after a change of operator
- Poor airflow at the canopy
Bursars and site managers at schools such as Parmiter's School tend to book extract cleaning for when the kitchen is empty.

Different parts, different methods
Schools, hospitals and care homes
Even a kitchen that cooks only a few hours a day needs cleaning at least every 12 months under BESA guidance. Holidays make it simple to schedule.
Grease filters
A filter that is missing or bent lets grease straight past. We check they fit as they should when we refit them, and flag any that do not.
