About our grease filter exchange in St Mary's
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the extract struggles. Regular exchange keeps the air moving. The work covers mesh filters, restaurants and pubs and island canopies, and the jobs we see most are filters that leave gaps in the canopy and grease left in baffles after washing.
In a smaller place like St Mary's, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Why act early in St Mary's
Once filters are saturated, more grease gets past them. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. A site near St Mary's that has to close at short notice is hard to cover for.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.

The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Because the survey comes first, a visit to St Mary's can usually be finished without a second trip.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site

FAQs for St Mary's
Can you get to a site in St Mary's?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Which fire service covers St Mary's?
That is Hampshire and Isle of Wight Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do you clean filters as well as exchanging them?
Yes. Some kitchens prefer their own filters cleaned on a schedule while others want an exchange. Either way, the canopy is not left without filters during service.
Do you handle baffle and mesh filters?
We exchange baffle and mesh filters. At the start, we note what your canopies use so the clean set always fits.
Will you tell us when the next visit is due?
Yes. How often depends on use and condition and the report sets out why.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What should go in our maintenance log?
Every certificate and report from each visit, filed in the maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Signs you need grease filter exchange in St Mary's
Filters get bent and damaged with handling. Damaged filters don’t sit flush, leaving gaps for grease to slip through.
Clients usually contact us after spotting one of these:
- Drips falling from the filters onto equipment
- Weak extraction at the canopy
- Grease filters clogged with grease
- A canopy running with filters missing
A kitchen near Southampton Central station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Kitchen extracts in St Mary's
St Mary's lies within about 1 mile of the sea. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. Food Standards Agency records list about 309 restaurants, cafés and works canteens and about 109 sandwich bars and takeaways in and around St Mary's, up to about a mile and a half out. Clogged filters slow the airflow, and busy kitchens like these clog them fast. In St Mary's, food businesses are inspected by environmental health officers from Southampton council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
Term dates shape school work: for a school like Hope Community School Southampton, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens, like those at hospitals such as Royal South Hants Hospital (about 0.5 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.
