How we handle ductwork cleaning in St Lawrence
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. If you’re dealing with thick crusts of old grease along the duct and grease pooling at the foot of the riser, we can put it right.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
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, and we are fully insured.

What affects the quote in St Lawrence
Every site gets its own quote. These are the things that affect it:
- The number of sites or systems
- Whether we need access equipment or extra panels
- Parking and loading at the site
- Any permits to work or inductions
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’re unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
Asking for a quote
We can often survey from photos. Try to include:
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then call us on 0345 646 2711 or email us.
Grease, kitchens and St Lawrence
The coast is only about 1 mile from St Lawrence. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Look up St Lawrence on the FSA’s food hygiene register and you’ll find about 8 cafés, restaurants and staff canteens and about 3 takeaways within roughly a mile and a half of the centre of St Lawrence. The duct above a busy canopy coats itself in grease long before anyone sees it. Hampshire and Isle of Wight Fire and Rescue Service covers St Lawrence. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Term dates shape school work: for a school like St Francis Catholic and Church of England Primary Academy, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near St Lawrence's Church, or anywhere in St Lawrence, may not know when the extract was last cleaned, and a grease test settles it.
St Lawrence is about 4 miles south-west of Shanklin, in the Isle of Wight. Every kind of commercial site in St Lawrence, ductwork cleaning is something we can help with. Visits can be booked for evenings, overnight or weekends so the site keeps running. Our area takes in 125 places across the Isle of Wight, from busy centres to quieter spots. Portsmouth is in our area too, about 17 miles from St Lawrence.

Local landmarks in St Lawrence
Typical jobs here are in premises near St Catherine's School and the streets around them. For rail, the closest station is Shanklin station, roughly 4.1 miles north-east. A little further out are Arthur Webster Memorial Hospital for Children (4.1 miles north-east) and Longshoremans Museum (1.3 miles east). Open spaces near St Lawrence include Stenbury Down.
How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes anything from a few hours to several visits, depending on the length of duct. Somewhere as small as St Lawrence, the date and timings are agreed with you well before the day.
- We trace the duct and find every way in.
- We take grease readings along the route.
- 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 pictures repeated, and unreachable sections recorded.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
- Dig out any earlier paperwork for the system
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.

What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Signs you need ductwork cleaning in St Lawrence
A duct with too few access doors can’t be fully cleaned. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
Any of these means the system needs a check-up:
- Proof of duct cleaning for the insurer
- Grease pooling at the foot of the riser
- A rancid smell from the extract duct
- Fat dripping from the ductwork
Healthcare kitchens, like those at hospitals such as Arthur Webster Memorial Hospital for Children (about 4.1 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common questions in St Lawrence
Is ductwork cleaning any different in a coastal place like St Lawrence?
It can. Salt air reaches St Lawrence, which is within about 1 mile of the coast, and it speeds up rust. Outdoor metalwork near the sea is worth inspecting at every visit.
Can you clean school kitchen extracts in St Lawrence during the holidays?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of St Lawrence, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How do you clean inside the ductwork?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
Do I get a certificate for ductwork cleaning?
Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Diarise the next duct clean
- Ask for a grease thickness test if the kitchen gets busier
- Don’t switch the extract off early
- Never cook with a filter missing
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
