Grease filter exchange for kitchens and businesses in Windsor
In Windsor, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often, lighter ones less. The interval is agreed before the first visit. The work covers wall canopies, baffle filters and mesh filters, and common reasons people get in touch are a canopy that drips grease and smoke and heat lingering under the hood.
Kitchens in towns like Windsor are often in older buildings that were never designed for them, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How the job changes from site to site
School, care home and staff kitchens
Visits can be planned around holidays and quieter periods so the filters are clean when cooking picks up.
Canopy filter housings
Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.
What grease filter exchange can’t fix
We will not sell you work that doesn’t address the problem, so here are the limits:
- Grease deep in the extract system
- Smell complaints that need odour control equipment
- A canopy too small for the cooking beneath it
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before booking.
Parts of the system we cover
- Restaurants and pubs
- School and hospital kitchens
- Island canopies
- Baffle filters
- Mesh filters
- Wall canopies
What else we do in Windsor
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Always run the extract while cooking
- Mention it if the kitchen gets busier
- Watch for grease drips between visits
- Do not refit a filter that’s bent
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due, and we can arrange it.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
What we are called out for in Windsor
Filters get bent and damaged with handling. A bent filter doesn’t seat properly and grease passes round them.
These are the problems we see most often:
- Missing filters in the filter bank
- Grease building up behind the canopy filters
- Poor airflow through the filters
- Drips falling from the filters onto equipment
Historic houses near Windsor, such as St Leonard's Hill about 1 mile south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Grease filter exchange around Windsor
Look up Windsor on the FSA’s food hygiene register and you will find about 164 restaurants, cafés and works canteens and about 19 takeaways within 1.5 miles or so of the middle of Windsor. Each canopy among them has filters that load with grease and need swapping or cleaning. Kitchens in Windsor get their food hygiene inspections from Windsor and Maidenhead council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Royal Berkshire Fire and Rescue Service covers Windsor. 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.
A hall kitchen that only cooks for events, whether near All Saints Church or elsewhere in Windsor, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like King Edward VII Hospital about 0.8 miles east, the extract may need cleaning more often than a part-time kitchen.

How we price grease filter exchange
Your quote is based on your site. We consider:
- Access, including roofs, risers and ceiling voids
- How big the system is
- The times the site is available
- The condition of the system
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What we need to know
Photos let us diagnose from a distance. Try to include:
- When the site is open and when it’s quiet
- The site address and the type of premises
- 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, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
Questions from Windsor
Which fire and rescue service is responsible for Windsor?
Royal Berkshire Fire and Rescue Service is the fire and rescue service for Windsor. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work overnight in Windsor?
Yes, we can come after you close and finish before you open. The work in Windsor can fit around your hours. Tell us your opening hours when you ask for a quote.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do I get a report after the visit?
Yes. It’s your proof that the work was done: a dated report with pictures, listing the work and any areas we couldn’t reach.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do we need to close while you work?
Not normally. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Can you give a price for filter changes?
Every kitchen is different, so we quote once we know your filters and schedule. We send you a fixed quote before the first visit.
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Let us know how to reach the roof or plant area at your site in Windsor, and where the van can go.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- 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
- Clear the space around the work
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711, or send details by email.

In-house cleaning or a specialist?
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.
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, which is where we come in.
