How the job changes from site to site
Roof-mounted fans
Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. We note any grease around the fan.
Impellers and blades
Coated blades move less air. We clean each blade back to its surface, so the fan can run as intended.
How we handle extract fan cleaning in Marshalswick
Every TR19® Grease clean includes the extract fan, but some fans need cleaning between full cleans, for example when it’s noisy or vibrating. A fan-only clean is recorded as exactly that. The work covers in-line fans, centrifugal fans and roof-mounted fans, and common reasons people get in touch are thick grease on the impeller and casing and grease escaping from the fan outlet.
Size does not change the work: a kitchen in a place like Marshalswick gets the whole system cleaned, canopy to discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Common problems we fix in Marshalswick
By the time air reaches the fan, it has passed the canopy, filters and duct. Whatever grease is still in it settles on the impeller and inside the housing where the spinning blades spread it around.
These are the problems we see most often:
- Grease stains around the discharge
- A smell of hot grease from the extract
- Grease around the motor and its mounts
- A fan that has never been cleaned
Term dates shape school work: for a school like St John Fisher Roman Catholic Primary School, an extract clean fits neatly into a half-term or summer break.

In-house cleaning or a specialist?
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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Why act early in Marshalswick
A fan that sounds rough in Marshalswick is often telling you the extract needs a clean. Grease on the fan means grease in the duct before it so a full TR19 clean may be due. When a site near Marshalswick shuts unexpectedly, the people who rely on it notice at once.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Check the report shows the fan was cleaned
- Listen for new noises or vibration from the fan
- Do not turn the fan off mid-service
- Report grease escaping from the fan
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Don’t run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes a few hours where there are several fans or heavy deposits. Tell us about any gates, ladders or locked plant areas at your site near Marshalswick when you book.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- 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 parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need

What extract fan cleaning looks like in Marshalswick
Food Standards Agency records include about 34 pubs, bars and clubs in and around Marshalswick, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Marshalswick is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Marshalswick are the job of St Albans City council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
Volunteers running a hall kitchen near Saint Mary's, or anywhere in Marshalswick, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens, like those at hospitals such as Hill End Hospital (about 1.1 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Questions from Marshalswick
Which fire authority looks after Marshalswick?
Fire safety enforcement in Marshalswick is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Will you come out to Marshalswick?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
Do you need to turn the fan off to clean it?
We always isolate the fan first, so it cannot run during the clean. With the extract off, the kitchen cannot cook, so we work out of hours.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
