Grease filter exchange in Woolstone
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. We point out any that need replacing. If you are dealing with damaged filters letting grease past and grease collecting in the filter channels, we can put it right, from school and hospital kitchens, mesh filters and wall canopies onwards.
Work in a small place like Woolstone 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.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Part by part
Canopy filter housings
Every exchange includes a check of how the filters sit since a gap is a route for grease.
Mesh filters
Older or smaller canopies often use mesh filters. They can be on the same exchange schedule as baffle filters.
What affects the quote in Woolstone
Your quote is based on your site. We take into account:
- The condition of the system
- A single visit or a regular plan
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
To speed up the quote, send us:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Why act early in Woolstone
Some kitchens in Woolstone wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. A planned visit to Woolstone is easier to arrange than an emergency callout.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
Why book with us
- A written report with photos after every visit
- We’re fully insured
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- A fixed price before any work starts

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too in Woolstone and across Oxfordshire. Work can be phased by floor, building or site around the people who use them.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Woolstone kitchens: local notes
Kitchens in Woolstone get their food hygiene inspections from Vale of White Horse council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand. The fire and rescue service for Woolstone is Oxfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in Woolstone, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Faringdon Day Hospital about 4.7 miles north, the extract may need cleaning more often than a part-time kitchen.
Woolstone is about 7 miles west of Wantage, in Oxfordshire. From the centre of Woolstone to the outskirts, grease filter exchange is available to all kinds of commercial premises, from a single unit to a large public building.

What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. The timing of a visit to Woolstone is set by you, and the travel is our side of the planning.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Before we arrive
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
Related advice
Common problems we fix in Woolstone
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.
Keep an eye out for any of the following:
- A greasy plenum behind the filters
- Poor airflow through the filters
- Filters so greasy the air can barely pass
- Staff short of time to wash filters
If your kitchen is in a listed or historic building, like the houses around Woolstone (Ashdown House is about 3.7 miles south), fitting access panels needs care.

Questions from Woolstone
Do you cover smaller places like Woolstone?
Yes. Woolstone is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Which environmental health team covers Woolstone?
In Woolstone, it’s Vale of White Horse council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How long does grease filter exchange take?
We will confirm the time with your quote. In most cases, the work takes well under an hour for most canopies.
How much does a filter exchange service cost?
Filters, canopies and how often you need visits all affect the price. Send us details or pictures and we’ll quote quickly.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Will you tell us when the next visit is due?
Yes. Every report includes a recommended date for the next visit, based on use and what we found.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
How often should grease filters be changed?
The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long, and we can change it.
