Fixed quotes for ductwork cleaning in Boxmoor
We quote each job individually. This is what makes a difference:
- The size of the system
- What state the system is in
- How easy every part is to reach
- The times the site is available
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
If you need ductwork cleaning in Boxmoor, give us a ring on 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Ductwork cleaning in Boxmoor, done properly
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. We are often asked to deal with duct runs that can’t be reached and fat dripping from the ductwork, on multi-storey ducts, access panels and horizontal duct runs.
For a smaller kitchen near Boxmoor, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Boxmoor questions
Which fire service covers Boxmoor?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Boxmoor. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you do school kitchen extract cleaning in Boxmoor in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 20 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Boxmoor. Just phone us on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
How much does ductwork cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, phone us on 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do I get a certificate for ductwork cleaning?
Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
What shows that the ducts need a clean?
The date on the last certificate is the first thing to check. No record, or a passed date, means it’s due, and grease readings will confirm how urgent it is.
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We reach it from the plenum side where possible.
Vertical risers
Risers are cleaned through panels at different levels. Any part that cannot be safely reached is recorded.
Grease, kitchens and Boxmoor
Food Standards Agency records include about 30 pubs and bars and about 3 hotels and B&Bs across Boxmoor and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s Dacorum council that sends environmental health officers to food businesses in Boxmoor. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. The fire and rescue service for Boxmoor is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 0.7 miles north-east, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near Church of St John the Evangelist and Attached Church Hall, or anywhere in Boxmoor, may not know when the extract was last cleaned, and a grease test settles it. For kitchens close to Hemel Hempstead station, where the day often starts early and ends late, the extract can be cleaned overnight.

Between visits
Simple habits between visits make a real difference. Our advice:
- Tell us if grease leaks from the ductwork
- Ask us about extra access panels where sections cannot be reached
- Have the grease measured if cooking hours go up
- Leave a way through to the access panels
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Some signs mean the duct needs attention sooner: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes from a few hours to more than one visit, depending on duct length and access. Because the survey comes first, a visit to Boxmoor can usually be finished without a second trip.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, pictures and a next clean date.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

Why act early in Boxmoor
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, and grease in the duct is part of that. Systems on quieter sites still build up dirt and wear, just more slowly.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
