What the work involves, part by part
Canopy filter housings
Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.
The plenum
Clean filters reduce the grease reaching the plenum, but it’s still cleaned during a full TR19 clean.
Grease filter exchange in North Mundham, done properly
We set up grease filter exchange for kitchens in North Mundham on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing, lighter ones less. The interval is agreed before the first visit. If you are dealing with filter washing that keeps being missed and damaged filters letting grease past, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
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.

Your questions about grease filter exchange in North Mundham
Does coastal air change anything about grease filter exchange in North Mundham?
It can. North Mundham is within about 3 miles of the coast, and salt air speeds up corrosion. Corroded fixings and housings are noted on the report so they can be dealt with.
Who is the fire and rescue service for North Mundham?
It’s West Sussex Fire and Rescue Service, which covers North Mundham. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How regularly do grease filters need exchanging?
That depends on the cooking. Heavy cooking means more frequent changes than kitchens that cook less. We agree the interval with you.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What should go in our maintenance log?
Anything that proves the system is maintained: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.
Where do the greasy filters go?
The greasy set leaves with us for cleaning, so your staff don’t have to wash them. Clean filters go straight in.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Let us know if your cooking hours increase
- Do not let the full clean slip because filters are changed
- Report a dripping canopy early
- Keep the extract on whenever the range is in use
The canopy looks cleaner and the air moves better right away. Keep the extract running while you cook so they catch grease as intended.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.

What staff can safely do
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 will take a look and send you a fixed quote.
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 they do not reach the grease that builds up further in. That part needs specialist access and equipment.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes less than an hour in most kitchens, and the area is cleaned down before we leave. A few photos of the system help us make the most of a visit to a place like North Mundham.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- At each visit, the greasy filters are lifted out.
