How we handle ductwork cleaning in Great Gaddesden
No two duct runs are the same, in Great Gaddesden or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route and finds every access point before we quote. If you have a duct nobody has opened in years and grease leaking from duct joints, we can put it right.
In a small place like Great Gaddesden, 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.
A written report with photos follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

What we do, step by step
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 the same goes into the written report. All told, the work takes from a few hours to more than one visit, depending on duct length and access. Somewhere like Great Gaddesden, lanes, gates and parking are worth mentioning in advance.
- We map the duct route and check where the access panels are.
- 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.
- We test again, take pictures and note any part that couldn’t be reached.
Before we arrive
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
- Let us know about permits to work or site inductions

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure filters are seated properly
- File each certificate and photo report in the maintenance log
- Diarise the next duct clean
- Consider fitting panels where the report shows gaps
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.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
What ductwork cleaning looks like in Great Gaddesden
The Food Standards Agency lists about 3 pubs, bars and clubs as registered food businesses in and around Great Gaddesden, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Great Gaddesden get their food hygiene inspections from Dacorum council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Hertfordshire Fire and Rescue Service covers Great Gaddesden. 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.
Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 3.2 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Great Gaddesden Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

How we price ductwork cleaning
Every site gets its own quote. These are the things that affect it:
- The size of the system
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
How the job changes from site to site
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. They collect grease as the air cools and slows, and we clean them section by section through access panels.
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. We test those as a separate job.
