Waterdale extract fan cleaning
Cleaning of kitchen extract fans, impellers, fan housings and discharge points for commercial sites in Waterdale and across Hertfordshire. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- A fan that no longer moves enough air
- Rough running from the extract fan
- A fan shaking on its mounts
Keeping the system healthy
So the system stays in good health:
- Flag smoke lingering at the canopy
- Listen for new noises or vibration from the fan
- Don’t turn the fan off mid-service
- Keep each photo report with the maintenance log
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Make sure the fan is reachable. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
How we handle extract fan cleaning in Waterdale
Every kitchen extract depends on its fan: it pulls air from the canopy, through the duct and out of the building. Whatever grease slips past the filters and duct reaches the fan and we clean it off. We’re often asked to deal with a fan that has never been cleaned and hot, greasy smells near the fan, on fan housings, in-line fans and roof-mounted fans.
Somewhere as small as Waterdale, 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.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Signs you need extract fan cleaning in Waterdale
Grease builds up unevenly on the blades. Over time, that imbalance shakes the fan, wearing bearings and mounts. Left too long, grease turns into wear.
What we’re most often called out for:
- Vibration from an unbalanced impeller
- A fan that no longer moves enough air
- A heavily greased fan housing
- A fan motor running hot under a coat of grease
School kitchens, at schools like Parmiter's School for example, are normally cleaned in the holidays so no lunches are lost.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
How we price extract fan cleaning
There’s no set price list, because no two systems are the same. What we look at:
- The condition of the system
- The size of the system
- Whether we need access equipment or extra panels
- The number of sites or systems
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
Helping us quote
When you call or email, these details help:
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
For a fixed quote, ring 0345 646 2711 or use the quote form 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. We normally come back within one working day.
Extract fan cleaning around Waterdale
The FSA’s data shows about 12 pubs, bars and clubs registered across Waterdale and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Waterdale is covered by 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. It’s Three Rivers council that sends environmental health officers to food businesses in Waterdale. 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.
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. Volunteers running a hall kitchen near Church of All Saints, or anywhere in Waterdale, may not know when the extract was last cleaned, and a grease test settles it.

What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes an hour or two for one fan, longer when it’s hard to reach. Photos of the system and how to reach it help us plan a visit to Waterdale.
- First we check the fan’s condition and how it sounds.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- The fan goes back into service with a report on its condition.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

Questions from Waterdale
Who is the fire and rescue service for Waterdale?
It’s Hertfordshire Fire and Rescue Service, which covers Waterdale. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who would carry out a food hygiene inspection at a kitchen in Waterdale?
That is Three Rivers council, whose environmental health officers carry out food hygiene inspections in Waterdale. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Do you provide a report after cleaning the fan?
A photo report shows the fan before and after. Full system cleans come with a TR19 certificate as well.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Is it safe to clean the fan while the kitchen is open?
We isolate the fan, so the kitchen can’t cook while we work. That is why fan cleans are done out of hours, and the kitchen is ready when we leave.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Part by part
Fan housings and motors
We clean around the motor without soaking its electrics, and the fan is isolated throughout. Grease around the motor can make it run hotter, so the surrounding area is cleaned carefully.
Wall fans
With little duct before them, wall fans collect grease fast. They can need regular attention, which grease readings will show.
