How we handle ductwork cleaning in Bower Heath
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we cannot is written down, so you know exactly where you stand. The work covers horizontal duct runs, attenuators and multi-storey ducts, and common reasons people get in touch are thick crusts of old grease along the duct and fat dripping from the ductwork.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from a few hours to several visits, depending on the length of duct, and the area is cleaned down before we leave. A few pictures of the system help us make the most of a visit to a place like Bower Heath.

Different parts, different methods
Attenuators and discharge
Near the discharge, the air has cooled the most, so it can collect more grease than expected. It’s tested and cleaned along with the rest.
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. Damper testing is a separate service.
Bower Heath questions
Can school kitchens in Bower Heath be cleaned in the holidays?
Yes, and it’s the easiest time to do it. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bower Heath. Booking early in the term gives the best choice of holiday dates.
Will you come out to Bower Heath?
Yes, Bower Heath is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can you price the work without visiting?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. Some sites still need a visit, and we will say so.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
How long will the duct clean take?
It depends on the length of the duct, the number of access panels and how much grease there is. Typically it takes anything from a few hours to several visits, depending on the length of duct.
Can extra access doors be added to the duct?
Yes, we fit access panels where the duct needs them. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
When something else is needed
In fairness, some problems need a different fix:
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
- Duct sections that need replacing
- Fire dampers that don’t close (they need testing and remedials)
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 the work covers
- Horizontal duct runs
- Attenuators
- Multi-storey ducts
- Bends and junctions
- Vertical risers
- Access panels
What happens if it’s left?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Leaving the duct makes those limits harder to keep to. It’s worth booking a check, because nobody sees inside a duct day to day.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.

Common problems we fix in Bower Heath
Damaged or poorly fitted filters let more grease into the duct. The duct then takes grease that the filters should have stopped and it fills faster.
The symptoms we are asked about most are:
- Sections of duct with no access panels
- Years of grease along the duct floor
- Grease seeping out of the duct seams
- A grease test showing the duct is overdue
If you run a church or community hall kitchen, near All Saints or elsewhere in Bower Heath, its extract still collects grease from every lunch and event.
