About our ductwork cleaning in Letchworth Garden City
We’ve been trading since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with each certificate issued through the BESCA portal. Common call-outs are for smells of old cooking grease from the ductwork and ductwork that has never been cleaned, on vertical risers, multi-storey ducts and horizontal duct runs.
Many kitchens in a town like Letchworth Garden City were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Fixed quotes for ductwork cleaning in Letchworth Garden City
The price is fixed before any work begins. It takes into account:
- The size of the system
- Parking and loading at the site
- A single visit or a regular plan
- The number of sites or systems
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or send details by email.
Aftercare tips
Once we’ve finished, these simple steps help:
- Tell us if grease leaks from the ductwork
- Keep grease filters clean and fitted whenever you cook
- Run the extract fan throughout service
- Book the next clean before the recommended date
Grease readings are taken again at the same set points, giving you before and after readings. Before and after photos sit next to the numbers.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
What happens if it’s left?
A dirty duct is something insurers ask about. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. A certificate that covers the ductwork is what they want to see. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Letchworth Garden City, having the work done and recorded first helps.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before work begins.

- In business since 2009
- Work around your opening hours, with 24/7 emergency cover
- Survey first, then a fixed quote

Signs you need ductwork cleaning in Letchworth Garden City
A greasy duct is a fire path, in Letchworth Garden City as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Common reasons sites call us include:
- Stale grease odours from the duct
- Grease pooling at the foot of the riser
- Thick crusts of old grease along the duct
- Ductwork that has never been cleaned
School kitchens, at schools like Pixmore Junior School for example, are normally cleaned in the holidays so no lunches are lost.
Comparing quotes
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the work can be done while the site is closed
- What records you will receive afterwards
- Whether the quote is based on a survey or photos
What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a few hours for a short run, longer for long runs and tall risers. Before the visit, a few photos of the system and how to reach it help us plan the work in Letchworth Garden City.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Getting ready for the visit
- Arrange a key holder or contact on site
- Dig out any earlier paperwork for the system
- Clear the space around the work
Ask for a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711, or email photos.

Common questions in Letchworth Garden City
Which fire service covers Letchworth Garden City?
Letchworth Garden City is in the area of Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can the work in Letchworth Garden City be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Letchworth Garden City doesn’t have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Can you clean ductwork with no access panels?
Ductwork needs access to be cleaned. We record those sections on the report and can fit access panels.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. If we need more, we will ask.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you cover Letchworth Garden City?
Yes. Our technicians work in Letchworth Garden City, as part of our area across London and the South East.
Do we need to close while you work?
Not typically. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
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.
What a clean will not put right
Ductwork cleaning cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- Duct sealed behind fixed ceilings or walls
- An extract fan that has stopped working
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think before you book.
What we work on in Letchworth Garden City
- Access panels
- Bends and junctions
- Horizontal duct runs
- Vertical risers
- Attenuators
- Multi-storey ducts
What the work involves, part by part
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Horizontal duct runs
Long horizontal runs need access panels at regular intervals. Any stretch out of reach is noted and can fit extra panels.
