Why act early in Underriver
A fan that fails mid-service can stop a kitchen cooking. Grease is often where fan trouble begins, so cleaning the fan helps keep it working. We also offer a 24/7 emergency callout if the worst happens. Equipment tucked in a roof space or outbuilding near Underriver rarely gets looked at unless someone books it.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.

Extract fan cleaning in Underriver
Grease on a fan isn’t spread evenly. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. Typical jobs include a fan that no longer moves enough air and a fan shaking on its mounts, on centrifugal fans, roof-mounted fans and fan housings.
In a small place like Underriver, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. 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 carry full insurance.

How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a couple of hours per fan, depending on its size and the build-up. In a small place like Underriver, the journey is planned ahead and the visit arranged around the site’s hours.
- We start by checking where the fan sits and how to isolate it.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- It’s closed up, run and checked, and pictures go into your report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
- Clear loose items from the work area
Get a fixed quote

Common problems we fix in Underriver
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
These are the problems we see most often:
- A noisy fan that has got louder over time
- Grease stains around the discharge
- A fan that no longer moves enough air
- An extract fan that vibrates or rattles
Volunteers running a hall kitchen near Church of St Margaret, or anywhere in Underriver, may not know when the extract was last cleaned, and a grease test settles it.

What extract fan cleaning looks like in Underriver

Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. In Underriver, food businesses are inspected by environmental health officers from Sevenoaks council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.

What affects the cost of extract fan cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- The condition of the system
- The size of the system
- Any permits to work or inductions
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- The site address and the type of premises
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Wall fans
Smaller kitchens may extract through a fan on an outside wall. It’s isolated, opened and cleaned inside and out.
