Ductwork cleaning in Bygrave
Not sure when the ductwork was last cleaned? 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. The work covers multi-storey ducts, access panels and horizontal duct runs, and the jobs we see most are stale grease odours from the duct and grease seeping out of the duct seams.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Ductwork cleaning in Bygrave: the local picture
There are about 8 restaurants, cafés and works canteens across Bygrave and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. In Bygrave, food businesses are inspected by environmental health officers from North Hertfordshire council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. The fire and rescue service for Bygrave is 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.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Fairfield Hospital is the nearest hospital to Bygrave, about 3.6 miles west. If you run a church or community hall kitchen, near Church of St Margaret of Antioch or elsewhere in Bygrave, its extract still collects grease from every lunch and event.

What else we do in Bygrave
Part by part
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. We agree a sequence that suits the building, out of hours where possible.
Access panels
After cleaning, every panel is closed and sealed, so grease and air stay inside the duct. We will tell you if any panel needs replacing.
FAQs for Bygrave
Do you work overnight in Bygrave?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you work in villages like Bygrave?
Yes, Bygrave is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do I get a certificate for ductwork cleaning?
A photo report, with readings and before and after pictures, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
How is kitchen extract ductwork cleaned?
After a survey and grease readings, the duct is opened up through its access panels. Each run and riser is scraped and degreased, then the readings are repeated.
How long will the duct clean take?
It takes a few hours for a short run, longer for long runs and tall risers. We will confirm the time when we quote.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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.
Why deal with it now?
A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains and grease can drip from duct joints. Planning a trip to Bygrave ahead is easier for everyone than a rushed one.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.

How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a few hours for a short run, longer for long runs and tall risers. For a village or hamlet like Bygrave, tell us about narrow lanes, gates and parking when you book.
- We start by working out how the duct runs and where it can be opened.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take photos and note any part that couldn’t be reached.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading
- Agree a time when the area can be out of use

Between visits
A little care between visits keeps the system in better shape. Our advice:
- Keep grease filters clean and fitted whenever you cook
- Don’t switch the extract off early
- Diarise the next duct clean
- Do not block access panels with shelving or stock
You will have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
Do you need ductwork cleaning in Bygrave?
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Common reasons sites call us include:
- Grease leaking from duct joints
- Smells of old cooking grease from the ductwork
- Proof of duct cleaning for the insurer
- Readings above 200 microns from a grease thickness test
School kitchens, at schools like The Knights Templar School for example, are typically cleaned in the holidays so no lunches are lost.
