About our ductwork cleaning in St Nicholas
If the ducts in St Nicholas haven’t been cleaned for a while, or nobody is sure when they were? Tell us about the system when you give us a ring on 0345 646 2711, or send details by email, and a fixed price will follow, normally within one working day. Common call-outs are for duct runs with no cleaning record and heavy grease at the base of a riser, on attenuators, horizontal duct runs and multi-storey ducts.
In a smaller place like St Nicholas, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Keeping the system healthy
So the system stays in good health:
- File each certificate and photo report in the maintenance log
- Do not block access panels with shelving or stock
- Ask us about extra access panels where sections cannot be reached
- Run the extract fan throughout service
Any section of duct we couldn’t reach is listed on the report and why. You can then decide whether to have access panels fitted.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few hours for a short run, longer for long runs and tall risers. Tell us when your site near St Nicholas is quiet and the visit will be booked for then.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- We open the panels and scrape out the heaviest grease.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take photos and note any part that couldn’t be reached.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet

St Nicholas: your questions answered
Is St Nicholas within the area you cover?
Yes, St Nicholas is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can a school canteen extract in St Nicholas be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 20 schools and colleges with food registrations within roughly a mile and a half of St Nicholas. You can ring 0345 646 2711, or send details by email with the dates the site is empty.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How much does ductwork cleaning cost in St Nicholas?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What do you do with what you remove?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Can you fit access panels in our ductwork?
Yes, extra panels can be fitted. It means more of the duct can be cleaned next time, and the report will show where they’re needed.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call 0345 646 2711 or use the quote form.
Leave it or put it right?
Fire inside a duct is out of sight and out of reach. It can travel through the ductwork to other parts of the building, so cleaning the duct is as important as cleaning the hood. It’s easy to lose track of when the work was last done on a quieter site.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

Ductwork cleaning in St Nicholas: the local picture
There are about 16 restaurants, cafés and works canteens and about 23 sandwich bars and takeaways within about 1.5 miles of central St Nicholas, according to the Food Standards Agency’s register. The duct above a busy canopy coats itself in grease long before anyone sees it. The fire and rescue service for St Nicholas is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In St Nicholas, food businesses are inspected by environmental health officers from Stevenage council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to St Nicholas is Lister Hospital, about 1.5 miles west. Church and community hall kitchens, near All Saints Church or anywhere around St Nicholas, are easy to forget, but their extracts collect grease like any other. Historic houses near St Nicholas, such as Aston Bury about 3.3 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, so the base is one of our test points.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
Staff cleaning versus specialist work
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, and that is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
