How we price ductwork cleaning
The quote reflects the site in front of us. We take into account:
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
- Whether several sites go on one quote
- How easy every part is to reach
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Where the site is and what kind of site it is
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
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. Add the site type and your opening hours, and many jobs can be priced from that alone.
Ductwork cleaning for kitchens and businesses in Hemel Hempstead
Each extract duct we take on in Hemel Hempstead goes through the full routine: we test the grease first, remove thick deposits by hand and degrease what’s left. Readings are taken again afterwards and photos go into your report. If you’re dealing with a rancid smell from the extract duct and proof of duct cleaning for the insurer, we can put it right, from bends and junctions, vertical risers and attenuators onwards.
Kitchens in a place the size of Hemel Hempstead are cleaned around trading, not the other way round: late at night, early in the morning or on a closed day. Bigger sites can be done kitchen by kitchen, so cooking carries on elsewhere.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What ductwork cleaning looks like in Hemel Hempstead
Food Standards Agency data counts about 108 restaurants, cafés and works canteens and about 69 takeaways within about 1.5 miles of central Hemel Hempstead. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Fire safety in Hemel Hempstead 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. Environmental health officers from Dacorum council inspect food businesses in Hemel Hempstead. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run a church or community hall kitchen, near St Barnabas or elsewhere in Hemel Hempstead, its extract still collects grease from every lunch and event. If you run catering at a historic house or estate in the area (High Elms Manor is about 4.6 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning.

The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes from a few hours to more than one visit, depending on duct length and access. Larger sites in Hemel Hempstead can be done in phases, out of hours, so part of the building keeps working.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- 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.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear loose items from the work area

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.

Part by part
Attenuators and discharge
Some systems have attenuators to reduce noise, but they can hold grease in their linings. We clean what can be reached and note anything that can’t.
Access panels
After cleaning, every panel is closed and sealed so the duct stays tight. A damaged panel is noted on the report.
What a clean won’t put right
Ductwork cleaning cannot fix everything, and we will tell you before we start. It will not put right:
- A failed fan motor at the end of the duct (a fan repair job)
- Ductwork that was poorly designed
- Duct sections that need replacing
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.
Parts of the system we cover
- Horizontal duct runs
- Multi-storey ducts
- Bends and junctions
- Attenuators
- Vertical risers
- Access panels
When to call us in Hemel Hempstead
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should and it fills faster.
If you notice any of these, it’s worth a diagnosis:
- Gaps where access panels were never fitted
- Readings above 200 microns from a grease thickness test
- Hardened, baked-on grease in long horizontal runs
- A duct clean needed for an insurer
Bursars and site managers at schools such as Broadfield Academy tend to book extract cleaning for when the kitchen is empty.
Questions to ask before booking
- How they set the interval to the next visit
- Whether a written report and pictures are included
- Exactly which parts of the system are covered
- Which accreditations they hold, and whether you can check them
Managing agents and facilities teams in Hemel Hempstead
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
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. With shared responsibility, good records help everyone.
Why act early in Hemel Hempstead
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy and grease can drip from duct joints. Records matter in Hemel Hempstead: insurers and inspectors may ask to see them.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
