Extract fan cleaning in Hemel Hempstead
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. Common call-outs are for a fan left out of previous cleans and a noisy fan that has got louder over time, across in-line fans, fan housings and axial fans.
In Hemel Hempstead, extract cleaning fits around service: after the last cover, before breakfast or on a day the kitchen is shut. Sites with more than one kitchen can be cleaned in phases.
We’ve 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.

Common questions in Hemel Hempstead
Do you clean school canteen extracts around Hemel Hempstead out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 30 schools, colleges and universities with registered kitchens within about a mile and a half of Hemel Hempstead. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
Can you come to Hemel Hempstead after we close?
Yes, we can come after you close and finish before you open. The work in Hemel Hempstead can fit around your hours. Let us know the hours you are closed and we’ll book within them.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Does a TR19 kitchen extract clean cover the fan?
Yes. TR19® Grease covers the whole system, fan included. It’s isolated, opened and cleaned along with the canopy, plenum, filters, ducts and discharge.
Why is my extract fan noisy?
Grease on the blades and housing is one of the usual causes, because it unbalances the fan. Worn bearings and motor problems are others, which our report will flag.
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.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Why act early in Hemel Hempstead
Cleaning the fan in Hemel Hempstead now is a short job: the work takes an hour or two for most single fans. Waiting adds vibration, wear and a harder clean. A gap in the records is hard to explain after an incident, so it pays to keep the work current.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Different parts, different methods
Inline duct fans
Inline fans can be in tight spaces, so we plan how to reach and clean them. If it can’t be reached fully, the report says so.
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 extract fan cleaning can’t fix
Before booking, it helps to know what’s not included:
- A fan that won’t start
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
If in doubt, call us on 0345 646 2711 or email us and we will say what we think before you book.
What we work on in Hemel Hempstead
- Centrifugal fans
- Axial fans
- Roof-mounted fans
- Discharge points
- In-line fans
- Fan housings
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a couple of hours per fan, depending on its size and the build-up. Larger sites in Hemel Hempstead can be done in phases, out of hours, so part of the building keeps working.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need

Staff cleaning versus specialist work
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Between visits
Good habits slow the build-up between visits. A few tips:
- Check filters are seated before cooking
- Keep each photo report with the maintenance log
- Do not turn the fan off mid-service
- Do not store items in front of the fan’s access point
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
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.
