Ductwork cleaning in Highfield, Hertfordshire
Looking for ductwork cleaning in Highfield? We diagnose first, fix the price and book the work around your hours, finishing with a written report and pictures.
- Proof of duct cleaning for the insurer

Do you need ductwork cleaning in Highfield?
Grease filters that don’t seal let fat straight through. The duct then takes grease that the filters should have stopped and it fills faster.
These are the problems we see most often:
- A grease test showing the duct is overdue
- Heavy grease at the base of a riser
- Stale grease odours from the duct
- A duct clean needed for an insurer
If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 1.1 miles south-west, the extract may need cleaning more often than a part-time kitchen.

What ductwork cleaning looks like in Highfield
Food Standards Agency records include about 26 bars, pubs and nightclubs and about 4 hotels, B&Bs and guest houses in and around Highfield, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Highfield falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Highfield, food businesses are inspected by environmental health officers from Dacorum council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Bursars and site managers at schools such as Yewtree Primary School tend to book extract cleaning for when the kitchen is empty. A hall kitchen that only cooks for events, whether near St Paul's or elsewhere in Highfield, still needs its extract cleaned, just less often.

What the work involves, part by part
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. They collect grease as the air cools and slows, so each section is cleaned through its access panels.
Vertical risers
Cleaning a riser needs access along its height. Any part that can’t be safely reached is recorded.
How we price ductwork cleaning
Your quote is based on your site. We take into account:
- How easy every part is to reach
- How big the system is
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
Asking for a quote
You don’t need the technical terms. It helps if you can send:
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Managing agents and facilities teams in Highfield
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Leave it or put it right?
Grease left in a duct in Highfield hardens over time. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. A planned visit to Highfield fits your hours; an emergency doesn’t.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

Your questions about ductwork cleaning in Highfield
Can school kitchens in Highfield be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 25 schools, colleges and universities with registered kitchens within about a mile and a half of Highfield. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who is the fire and rescue service for Highfield?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Highfield. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
How do you clean inside the ductwork?
We get into the duct through its access panels. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
What if part of the duct can’t be reached?
We clean everything we can reach and record what we cannot. Fitting extra access panels is the usual answer, and we can do that for you.
