Ashford questions
Can you work in Ashford outside opening hours?
Yes, evening, overnight and weekend work is normal for us. It means the site in Ashford keeps running as normal. Your opening times are the first thing we ask for.
Do you clean school canteen extracts around Ashford out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 19 schools, colleges and universities with registered kitchens within about a mile and a half of Ashford. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which records should we keep?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
How regularly do grease filters need exchanging?
It varies from kitchen to kitchen. The schedule is based on how heavily you cook, and adjust it if needed.
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 the clean set always fits.
Where do the greasy filters go?
The greasy set leaves with us for cleaning, so your staff don’t have to wash them. A clean set is fitted in their place.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
About our grease filter exchange in Ashford
We run grease filter exchange for all kinds of kitchens in Ashford, from a single canopy to several. We can come before or after service so nobody has to stop cooking. The work covers island canopies, baffle filters and mesh filters, and people most often call us about a canopy that drips grease and poor airflow through the filters.
Most kitchens in a town like Ashford can’t close for a day, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes well under an hour for most canopies. Parking in a town like Ashford is usually straightforward, so the main questions are access and timing.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- 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 loose items from the work area
- Let us know about parking and loading
- Name a contact who can let us in at the agreed time
Get a fixed quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Common problems we fix in Ashford
Repeated removal and washing takes its toll on filters. Damaged filters do not sit flush and grease passes round them.
Keep an eye out for these warning signs:
- Hand-washed filters that still look greasy
- Filters that leave gaps in the canopy
- Grease collecting in the filter channels
- Filter washing that keeps being missed
If you run a café or takeaway near Ashford Surrey station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What else we do in Ashford
Between visits
Results last longer with the right care. We suggest:
- Watch for grease drips between visits
- Keep canopy surfaces wiped down
- Keep the extract on whenever the range is in use
- Keep filter exchange and TR19 cleaning on the same plan
Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
What affects the quote in Ashford
Every site gets its own quote. This is what makes a difference:
- Any permits to work or inductions
- The condition we find in the survey
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
Helping us quote
When you contact us, these details help:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- Where the site is and what kind of site it is
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
Ashford kitchens: local notes
According to Food Standards Agency records, there are about 8 pubs, bars and clubs across Ashford and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Environmental health officers from Spelthorne council inspect food businesses in Ashford. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Ashford is Surrey Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Ashford is Ashford Hospital, about 0.7 miles north. A hall kitchen that only cooks for events, whether near Parish Church of St Matthew or elsewhere in Ashford, still needs its extract cleaned, just less often.
