- Grease left in baffles after washing
What staff can safely do
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
How we handle grease filter exchange in Catford
We run grease filter exchange for all kinds of kitchens in Catford, from a single canopy to several. We can come before or after service, so cooking is not interrupted. We’re often asked to deal with grease left in baffles after washing and filter washing that keeps being missed, across restaurants and pubs, school and hospital kitchens and island canopies.
Kitchens in Catford, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What happens on the day
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes a short visit, depending on how many filters the canopies hold. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Catford.
- We start by noting how many filters you have and what type they are.
- A change schedule is agreed to match the kitchen’s cooking hours.
- Each visit starts with the used filters being removed.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload

We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or use the quote form.

Why it’s worth doing now in Catford
Some kitchens in Catford wash filters themselves to save the cost of a service, and it works when it’s done well and never skipped. Where it slips, an exchange service takes the job off staff. Every month a London system goes without attention adds to what has to be done later.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before any work starts.

Grease filter exchange around Catford
The Food Standards Agency lists about 32 pubs and bars and about 3 hotels and B&Bs as registered food businesses in and around Catford, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In Catford, food businesses are inspected by environmental health officers from Lewisham council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. London Fire Brigade covers Catford. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you look after a school kitchen, at a school such as Holy Cross Catholic Primary School or anywhere near Catford, the holidays are the usual time for a TR19® clean. If you run catering at a healthcare site, such as a hospital like University Hospital Lewisham about 0.8 miles north, the extract may need cleaning more often than a part-time kitchen. A kitchen near Catford Bridge station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Catford questions
Do you work overnight in Catford?
Yes, nights and weekends are routine for us. It means the site in Catford keeps running as normal. Tell us your opening hours when you ask for a quote.
Can a school canteen extract in Catford be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 46 schools, colleges and universities with registered kitchens within about a mile and a half of Catford. You can call us on 0345 646 2711 or email us with the dates the site is empty.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What types of filter do you exchange?
We exchange baffle and mesh filters. At the start, we note what your canopies use so the clean set always fits.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
What if some of our filters are damaged?
A bent filter leaves a gap for grease. We flag any we find and explain what’s needed.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Fixed quotes for grease filter exchange in Catford
Your quote is based on your site. We take into account:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- What state the system is in
- One-off work versus a regular cycle
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
What we need to know
Photos let us diagnose from a distance. Try to include:
- A few general shots of the system
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Between visits
Once we have finished, these simple steps help:
- Watch for grease drips between visits
- Keep the canopy clear for exchange visits
- Never cook with the extract switched off
- Report damaged filters so they can be replaced
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us for cleaning.
If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
