Ductwork cleaning in Northchurch, done properly
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey and finds every access point before we quote. Common call-outs are for a rancid smell from the extract duct and duct runs that can’t be reached, on attenuators, bends and junctions and access panels.
Around a smaller place like Northchurch, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Make sure filters are seated properly
- Keep the fan on while anything is cooking
- Leave a way through to the access panels
- Get panels fitted where the duct couldn’t be cleaned
Any section of duct we couldn’t reach is listed on the report, with the reason. You can then decide whether to have access panels fitted.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Northchurch kitchens: local notes
There are about 38 restaurants, cafés and works canteens and about 10 sandwich bars and takeaways within about 1.5 miles of central Northchurch, 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 Northchurch 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. Kitchens in Northchurch get their food hygiene inspections from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Cholesbury Manor House is about 3 miles west), access may need planning. If you look after a school kitchen, at a school such as St Mary's CofE Primary School or anywhere near Northchurch, the holidays are the usual time for a TR19® clean. If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 5.2 miles east, the extract may need cleaning more often than a part-time kitchen.

How the job changes from site to site
Bends and transitions
Wherever the duct turns or changes size, grease builds up. Slowing air leaves grease behind, so we clean these points carefully.
Multi-storey and shared buildings
A fire in a duct in a shared building can affect far more than one kitchen, which makes keeping it clean all the more important. Your certificate and report give building managers the record they need.
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
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.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes anything from a few hours to several visits, depending on the length of duct. Tell us about any gates, ladders or locked plant areas at your site near Northchurch when you book.
- We start by working out how the duct runs and where it can be opened.
- 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.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Clear loose items from the work area
- Let us know about parking and loading
- Have your last certificate or report to hand

How we price ductwork cleaning
The quote reflects the site in front of us. We take into account:
- The condition of the system
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- Working hours and out-of-hours timing
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- A few general shots of the system
- Any access panels or hatches you can see
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
FAQs for Northchurch
Do you clean school canteen extracts around Northchurch out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 10 schools and colleges with food registrations within roughly a mile and a half of Northchurch. Booking early in the term gives the best choice of holiday dates.
Can the work in Northchurch be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
How long does ductwork cleaning take?
Duct length, access and grease levels all affect it. Typically it takes from a few hours to more than one visit, depending on duct length and access.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
How much does ductwork cleaning cost in Northchurch?
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 happens if it’s left?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. Around Northchurch, a kitchen or building out of action is missed straight away.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
