Ductwork Cleaning in Northaw
Our technicians work in Northaw on ductwork cleaning. Fixed quotes, work around your opening hours and photo reports as standard.
- An insurer asking for TR19 evidence
- Stale grease odours from the duct
- A duct nobody has opened in years
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
About our ductwork cleaning in Northaw
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that’s where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. If you are dealing with ductwork that has never been cleaned and grease pooling at the foot of the riser, we can help, from attenuators, horizontal duct runs and multi-storey ducts onwards.
In a small place like Northaw, kitchens are often in older or extended buildings, with long single-storey duct runs, 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. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Ask us about extra access panels where sections can’t be reached
- Flag drips from the duct right away
- Keep the fan on while anything is cooking
- Never cook with a filter missing
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
Ductwork cleaning around Northaw
The FSA’s data shows about 6 bars, pubs and nightclubs registered within roughly a mile and a half of the centre of Northaw. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Northaw are the job of Welwyn Hatfield council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in Northaw falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If your kitchen is in a listed or historic building, like the houses around Northaw (Wyllyotts Manor is about 2.1 miles west), fitting access panels needs care. Church and community hall kitchens, near Parish Church of St Thomas A Becket or anywhere around Northaw, are easy to forget, but their extracts collect grease like any other. A hospital like Chase Farm Hospital, about 3.3 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

How it works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like Northaw, tell us about narrow lanes, gates and parking when you book.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- 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
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Agree a time when the area can be out of use
- Find the previous report, if there is one

Why it’s worth doing now in Northaw
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. In a place like Northaw, ductwork and fans are easy to forget until something goes wrong.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

In-house cleaning or a specialist?
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, next to our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What the work involves, part by part
Access panels
Extra panels can be installed where there are gaps, so the next clean reaches more of the system. We’ll recommend where they should go.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
