Grease filter exchange in Cookham Dean
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. If you are dealing with damaged filters letting grease past and grease left in baffles after washing, we can help, from school and hospital kitchens, restaurants and pubs and baffle filters onwards.
For a kitchen in or near Cookham Dean, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What affects the cost of grease filter exchange
We do not publish a price list, because sites vary so much. The quote depends on:
- How many systems or sites are involved
- Parking and loading at the site
- How easy every part is to reach
- The scale of the work
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, gather:
- Problems your staff have spotted
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
For a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
Cookham Dean questions
Can the work in Cookham Dean be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Cookham Dean needn’t be disturbed. Just ring 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Who inspects food businesses in Cookham Dean?
The local authority for Cookham Dean is Windsor and Maidenhead council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Is there a cleaning option for the filters we have?
We can. Cleaning your existing filters is an option while others want an exchange. We make sure the canopy is ready for service either way.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Do we lose a day’s trading?
Usually not. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
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.
Do you handle baffle and mesh filters?
The common types of grease filter: baffle and mesh. Tell us what you have when you give us a ring on 0345 646 2711 or email us and we’ll confirm it on site.
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes well under an hour for most canopies, and the area is cleaned down before we leave. Somewhere like Cookham Dean, lanes, gates and parking are worth mentioning in advance.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.
Advice
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Wipe the outside of the canopy as part of daily cleaning
- Make sure we can reach the canopy on exchange day
- Never leave gaps in the filter bank
- Book full TR19 cleans alongside filter changes
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease, so let us know if one goes missing or gets damaged.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.
Kitchen extracts in Cookham Dean
The FSA’s food hygiene register shows about 19 restaurants, cafés and works canteens and about 5 takeaways and sandwich shops in and around Cookham Dean, up to about a mile and a half out. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Environmental health officers from Windsor and Maidenhead council inspect food businesses in Cookham Dean. 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. Cookham Dean sits within the area of Royal Berkshire 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.
If you look after a school kitchen, at a school such as Cookham Dean CofE Primary School or anywhere near Cookham Dean, the holidays are the usual time for a TR19® clean. If you run catering at a historic house or estate in the area (Cliveden is about 2.5 miles east), event kitchens in older buildings often have awkward duct runs that need planning.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Common problems we fix in Cookham Dean
Wherever you are, Cookham Dean included, filter washing is the job that gets skipped when the kitchen is busy. A missed wash or two is all it takes for a filter bank to clog.
Signs it’s time to call us include:
- Hand-washed filters that still look greasy
- Staff short of time to wash filters
- Grease dripping from the canopy
- Poor airflow through the filters
If you run a church or community hall kitchen, near Church of St John the Baptist or elsewhere in Cookham Dean, its extract still collects grease from every lunch and event.
Questions to ask before booking

- When the next visit should be, and why
What grease filter exchange can’t fix
Grease filter exchange can’t fix everything, and we will tell you before work begins. It won’t put right:
- Odours from the discharge that filters won’t stop
- Grease deep in the extract system
- An extract that was undersized from the start
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.

Why act early in Cookham Dean
Grease-loaded filters are a fire risk in their own right. A flare-up on the range can reach them, and from there into the duct. Keeping filters clean takes some of that fuel away. A planned visit to Cookham Dean is easier to arrange than an emergency callout.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
