Common problems we fix in Langley
Grease in a duct running from a kitchen in Langley is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
The symptoms we’re asked about most include:
- Duct runs that cannot be reached
- Thick crusts of old grease along the duct
- High readings at a recent grease test
- A duct clean needed for an insurer
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Knebworth House is about 1.3 miles south-east), access may need planning.

Ductwork cleaning in Langley
We have been trading since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. Typical jobs include ductwork that has never been cleaned and duct runs that can’t be reached, across multi-storey ducts, access panels and vertical risers.
Work in a small place like Langley starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What ductwork cleaning looks like in Langley
The FSA’s data shows about 4 pubs, bars and clubs registered within roughly a mile and a half of the centre of Langley. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. The fire and rescue service for Langley 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. In Langley, food businesses are inspected by environmental health officers from North Hertfordshire council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
A hospital like Lister Hospital, about 2.7 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as The Thomas Alleyne School tend to book extract cleaning for when the kitchen is empty.

Landmarks near Langley
We work in commercial kitchens and buildings around Concerts at Knebworth House and Farmers Boy Public House, among other places. The closest station to Langley is Stevenage station, roughly 1.5 miles north-east of the centre. A little further out are Lister Hospital (2.7 miles north) and Wymondley Castle (3.7 miles north).

Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes a few hours for a short run, longer for long runs and tall risers. Visits to a village like Langley are booked in advance, at a time that suits whoever runs the site.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Clear the space around the work
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem 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.

Why it’s worth doing now in Langley
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean straight away. Leaving the duct makes those limits harder to keep to. If the system at a site near Langley fails, there may be nowhere nearby to move to.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before we start.

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. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. We test those as a separate job.
What ductwork cleaning can’t fix
Some problems need a different service or another trade:
- A worn-out fan that needs replacing
- Leaking duct joints that need repair
- A damper stuck open in the duct
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we will tell you honestly before booking.
