Grease filter exchange for kitchens and businesses in Woodmansterne
Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. The work covers baffle filters, school and hospital kitchens and wall canopies, and common reasons people get in touch are a greasy plenum behind the filters and grease filters clogged with grease.
Size doesn’t change the work: a kitchen in a place like Woodmansterne gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- A canopy that does not capture the vapour properly
- A noisy or failed extract fan
- Greasy ducts and risers that a filter change won’t reach
If in doubt, ring 0345 646 2711, or email photos and we’ll say what we think before booking.
Parts of the system we cover
- School and hospital kitchens
- Restaurants and pubs
- Mesh filters
- Baffle filters
- Wall canopies
- Island canopies
Leave it or put it right?
Grease dripping from the canopy is a sign the filters can’t hold any more. Drips land on surfaces and equipment below and that’s the kind of thing inspectors look for. Systems on quieter sites still build up dirt and wear, just more slowly.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What you get with us
- Evenings, overnight and weekends, plus 24/7 emergency callout
- We are fully insured
- Photo reports with every job
- A fixed price before any work starts

What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes less than an hour in most kitchens. Tell us about any gates, ladders or locked plant areas at your site near Woodmansterne when you book.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- 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.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
Getting a quote
Getting a quote does not take long. 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.

What affects the quote in Woodmansterne
We don’t publish a price list, because sites vary so much. What we look at:
- Where the site is and how we reach it
- The condition we find in the survey
- One-off work versus a regular cycle
- The size of the system
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
To help 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. Once you have those, call 0345 646 2711 or send us an email.
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Clean the canopy surfaces regularly
- Tell us if a filter is bent or damaged
- Let us know if your cooking hours increase
- Keep the canopy clear for exchange visits
Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to keep up.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.
Questions from Woodmansterne
Can you come to Woodmansterne after we close?
Yes, we can come after you close and finish before you open. It means the site in Woodmansterne keeps running as normal. Your opening times are the first thing we ask for.
Who inspects food businesses in Woodmansterne?
Food hygiene inspections in Woodmansterne are carried out by Reigate and Banstead council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you handle baffle and mesh filters?
Both baffle filters and mesh filters are covered. At the start, we note what your canopies use so every set we bring fits.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Do we lose a day’s trading?
Not usually. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What we are called out for in Woodmansterne
Sometimes a filter is taken out and never put back. A missing filter leaves an open route into the system where it settles out of sight.
Most sites get in touch when they notice one of these:
- A greasy plenum behind the filters
- Filters that leave gaps in the canopy
- Filters so greasy the air can barely pass
- A canopy running with filters missing
If you run a café or takeaway near Chipstead station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
What to look for in a quote
- What insurance they carry
- Proof of accreditation you can verify
- How they set the interval to the next visit
- What happens if part of the system can’t be accessed
Woodmansterne kitchens: local notes
The FSA’s food hygiene register includes about 13 pubs, bars and clubs across Woodmansterne and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Woodmansterne, food businesses are inspected by environmental health officers from Reigate and Banstead council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Woodmansterne sits within the area of Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Term dates shape school work: for a school like Chipstead Valley Primary School, an extract clean fits neatly into a half-term or summer break. If you run a church or community hall kitchen, near St Peter's Church or elsewhere in Woodmansterne, its extract still collects grease from every lunch and event.

Part by part
The plenum
A greasy plenum is a sign filters have been left too long or that the next TR19 clean is due.
Baffle filters
Baffle filters are a common choice for commercial canopies. They still need regular cleaning, because the grease they collect builds up.
