Ductwork Cleaning in Potten End
Ductwork cleaning for businesses, landlords and public buildings in Potten End. CHAS, SafeContractor and ISO 9001, and fully insured.
- Heavy grease at the base of a riser
- Years of grease along the duct floor
- Gaps where access panels were never fitted
What we are called out for in Potten End
A duct with too few access doors cannot be fully cleaned. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
If you notice any of these, it’s worth a diagnosis:
- Grease leaking from duct joints
- Duct runs that can’t be reached
- Thick crusts of old grease along the duct
- Grease pooling at the foot of the riser
A hall kitchen that only cooks for events, whether near Church of the Holy Trinity or elsewhere in Potten End, still needs its extract cleaned, just less often.
Questions to ask before you book
- Whether the work can be done while the site is closed
- What insurance they carry
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What happens if part of the system can’t be accessed
Ductwork cleaning in Potten End, done properly
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Removing it is the whole point. We are often asked to deal with ductwork that has never been cleaned and thick crusts of old grease along the duct, across vertical risers, multi-storey ducts and attenuators.
In a village or hamlet like Potten End, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
The paperwork matters as much as the work. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Potten End questions
Do you work at weekends in Potten End?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Potten End needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Which fire authority looks after Potten End?
That’s Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. As a guide, it takes a shift or more, depending on the length of the runs and the number of access points.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Landlords, agents and facilities managers
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
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.
What happens if it’s left?
A dirty duct is something insurers ask about. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. A certificate that covers the ductwork is what they want to see. A fault that closes a site in a village like Potten End affects everyone who depends on it.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.
What you get with us
- One number for every site across the South East and London
- Every job surveyed first
- In business since 2009
- A written report with photos after every visit
Between visits
How long the results last depends on use and care. We suggest:
- Tell us if grease leaks from the ductwork
- Keep your cleaning records together
- Don’t switch the extract off early
- Book the next clean before the recommended date
Every panel we open is refitted when we finish, and the area around them is cleaned down. Grease and dirty water are contained and removed.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
Part by part
Access panels
Access panels are the doors that let us into the duct. Where there are none, those sections cannot be cleaned and the report has to say so.
Bends and transitions
Wherever the duct turns or changes size, grease builds up. The air slows and drops its load, so these points get extra attention.

Fixed quotes for ductwork cleaning in Potten End
The diagnosis comes before the price. We look at:
- The size of the system
- Whether several sites go on one quote
- What state the system is in

What to send for a quote
We can often survey from photos. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it

How it works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes from a few hours to more than one visit, depending on duct length and access. A few photos of the system help us make the most of a visit to a place like Potten End.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- We test again, take photos and note any part that couldn’t be reached.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
