How we handle grease filter exchange in Crowell
Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers wall canopies, restaurants and pubs and baffle filters, and the jobs we see most are grease building up behind the canopy filters and a canopy that drips grease.
Work in a small place like Crowell starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Every visit ends with a written report and photos, 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.

How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes anything from a few minutes to an hour or so, depending on the number of filters. Somewhere like Crowell, lanes, gates and parking are worth mentioning in advance.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- At each visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions

Advice
Fixed quotes for grease filter exchange in Crowell
We quote each job individually. These are the things that affect it:
- Travel, parking and unloading
- The number of sites or systems
- How easy every part is to reach
- The condition of the system
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.
What we need to know
What to send for a quote:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
How the job changes from site to site
Baffle filters
A clogged baffle filter restricts airflow. A clean exchange set brings the airflow back.
Mesh filters
Mesh filters are still found in many canopies. We exchange them on the same basis as baffles.
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Crowell questions
Do you work at weekends in Crowell?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Which fire and rescue service is responsible for Crowell?
It’s Oxfordshire Fire and Rescue Service, which covers Crowell. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Which grease filters does the service cover?
We work with both baffle and mesh filters. The first step is recording what you have and set up the service around them.
Can damaged filters stay in the canopy?
A bent filter leaves a gap for grease. We point them out on the visit so they can be replaced.
Do you recommend a next date?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Can you clean our existing filters instead?
Yes, that is an option. The first step is looking at the filters you have, as damaged ones may be better replaced.

Signs you need grease filter exchange in Crowell
Washing filters by hand doesn’t always get them clean. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
What we are most often called out for:
- A canopy that drips grease
- Grease left in baffles after washing
- Blocked baffle filters
- Weak extraction at the canopy
A hall kitchen that only cooks for events, whether near Church of the Nativity of the Blessed Virgin Mary or elsewhere in Crowell, still needs its extract cleaned, just less often.

What your team can do, and what needs us
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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
What grease filter exchange looks like in Crowell
The FSA’s food hygiene register shows about 5 cafés, restaurants and staff canteens in and around Crowell, up to about a mile and a half out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Environmental health officers from South Oxfordshire council inspect food businesses in Crowell. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. The fire and rescue service for Crowell is Oxfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
School kitchens, at schools like Mill Lane Community Primary School for example, are usually cleaned in the holidays so no lunches are lost. Historic houses near Crowell, such as Adwell House about 2.9 miles west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
