Ductwork cleaning in Rush Green, Hertfordshire
Ductwork cleaning for Rush Green and the surrounding area: diagnosis first, then a fixed quote, the work and a report with photos. Ask us for a fixed quote.
- Duct runs that cannot be reached
- Hardened, baked-on grease in long horizontal runs
- Stale grease odours from the duct
Between visits
So the system stays in good health:
- Keep grease filters clean and fitted whenever you cook
- Tell us if grease leaks from the ductwork
- Keep your cleaning records together
- Keep to the interval on the report
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
About our ductwork cleaning in Rush Green
Grease in a duct is hidden, which is exactly why it’s dangerous. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. If you have sections of duct with no access panels and heavy grease at the base of a riser, we can put it right, from bends and junctions, access panels and horizontal duct runs onwards.
For a kitchen in or near Rush Green, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
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, and we are fully insured.

Signs you need ductwork cleaning in Rush Green
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
The symptoms we’re asked about most are:
- Readings above 200 microns from a grease thickness test
- Grease seeping out of the duct seams
- Hardened, baked-on grease in long horizontal runs
- Ductwork that has never been cleaned
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Knebworth House is about 2.1 miles south-east), access may need planning.

What the work involves, part by part
Attenuators and discharge
At the end of the duct is the discharge. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Access panels
We can fit new access panels where the duct needs them, making future cleans more complete. We will recommend where they should go.

What ductwork cleaning looks like in Rush Green
According to Food Standards Agency records, there are about 8 bars, pubs and nightclubs within about 1.5 miles of central Rush Green. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Rush Green get their food hygiene inspections from North Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. Hertfordshire Fire and Rescue Service covers Rush Green. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
School kitchens, at schools like The Thomas Alleyne School for example, are usually cleaned in the holidays so no lunches are lost. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Rush Green is Lister Hospital, about 2.2 miles north-east.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a shift or more, depending on the length of the runs and the number of access points, and the area is cleaned down before we leave. We agree a date with you, plan the drive to Rush Green and turn up when the site is quiet.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Post-clean readings and photos go into the report, with any unreachable section listed.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool

What affects the cost of ductwork cleaning
We quote each job individually. This is what makes a difference:
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- A single visit or a regular plan
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 we start.
Asking for a quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Any access panels or hatches you can see
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.
Leave it or put it right?
Booking the duct clean in Rush Green now keeps it a planned job. It takes from a few hours to more than one visit, depending on duct length and access, done out of hours so the kitchen keeps cooking. It’s worth booking a check, because nobody sees inside a duct day to day.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Your questions about ductwork cleaning in Rush Green
Which council inspects kitchens in Rush Green?
Kitchens in Rush Green are inspected by North Hertfordshire council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Do you work in villages like Rush Green?
Yes. Rush Green is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Grease is scraped out first, then degreased, with readings taken before and after.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
When is the ductwork cleaned?
We clean while the kitchen is closed, so evenings, nights and weekends are all possible. Equipment and the extract are switched off while we work.
How much does ductwork cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711 or send us an email and tell us about the site and its opening hours.

Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
