How we handle extract fan cleaning in Watford Heath
The fan is cleaned as part of every full TR19® Grease clean, but some fans need cleaning between full cleans, especially when it has started to vibrate or sound rough. Where only the fan is cleaned, the report says so. Common call-outs are for a fan that hums, whines or rumbles and fat spreading onto the roof or wall by the fan, on discharge points, roof-mounted fans and fan housings.
Size does not change the work: a kitchen in a place like Watford Heath gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Extract fan cleaning in Watford Heath: the local picture
There are about 119 cafés, restaurants and staff canteens and about 37 takeaways and sandwich shops across Watford Heath and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Fire safety in Watford Heath falls to 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. Food hygiene inspections in Watford Heath are the job of Watford council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you look after a school kitchen, at a school such as Bromet Primary School or anywhere near Watford Heath, the holidays are the usual time for a TR19® clean. Volunteers running a hall kitchen near Church of St Matthew, or anywhere in Watford Heath, may not know when the extract was last cleaned, and a grease test settles it.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

What else we do in Watford Heath
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Watford Heath: your questions answered
Which fire service covers Watford Heath?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Watford Heath. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who would carry out a food hygiene inspection at a kitchen in Watford Heath?
In Watford Heath, it’s Watford 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.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Is TR19 a legal requirement?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
What paperwork do I get after a fan clean?
You get a photo report with before and after photos of the fan. If it’s part of a full TR19 clean, a TR19 certificate is issued too.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Which accreditations do you hold?
Duct Doctor is 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.
When something else is needed
To be straight with you, some problems need a different fix:
- An impeller that is bent or split
- A motor that has burnt out
- An undersized fan that can’t cope
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly before you book.
What the work covers
- Roof-mounted fans
- Axial fans
- Centrifugal fans
- Discharge points
- In-line fans
- Fan housings
Looking after it afterwards
To keep the system working properly between visits:
- Check filters are seated before cooking
- Leave a clear route to the fan
- Tell us if the extract feels weaker
- Keep the fan on whenever the range is lit
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
How the job changes from site to site
Roof-mounted fans
Roof fans sit at the top of the riser. They’re cleaned where safe access allows, and anything we can’t reach is recorded.
Kitchens with long cooking hours
A long-hours kitchen cannot afford a fan failure. Keeping the fan clean is part of avoiding that, and our 24/7 emergency callout is there if it happens anyway.
What we are called out for in Watford Heath
How fast a fan gets greasy in Watford Heath depends on the cooking: how many hours a day the kitchen runs and what it cooks. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Keep an eye out for these warning signs:
- Less air being pulled from the kitchen
- Hot, greasy smells near the fan
- A fan coated in grease inside its housing
- Fat spreading onto the roof or wall by the fan
A kitchen near Bushey station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What your quote should include
- Whether they’re fully insured
- What paperwork you get at the end
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether a survey comes first
What we do, step by step
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes an hour or two for one fan, longer when it’s hard to reach. In a smaller place like Watford Heath, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
Getting ready for the visit
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
