- Grease left in baffles after washing
- Poor airflow through the filters
- Grease building up behind the canopy filters
What the work involves, part by part
Busy restaurant and pub kitchens
High-output kitchens clog filters quickly. Their exchange schedule is usually the tightest.
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease is thrown out of the airstream and collects on the baffles.
How we handle grease filter exchange in Fawley Bottom
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers school and hospital kitchens, island canopies and baffle filters, and common reasons people get in touch are grease collecting in the filter channels and poor airflow through the filters.
In a village or hamlet like Fawley Bottom, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Duct Doctor has been trading since 2009, as 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.

Common problems we fix in Fawley Bottom
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up so changes need to come round sooner.
Signs it’s time to call us include:
- Weak extraction at the canopy
- Staff short of time to wash filters
- Grease filters clogged with grease
- Hand-washed filters that still look greasy
Historic houses near Fawley Bottom, such as Stonor Park about 1.5 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Your questions about grease filter exchange in Fawley Bottom
Who would carry out a food hygiene inspection at a kitchen in Fawley Bottom?
That’s Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Fawley Bottom. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Is Fawley Bottom within the area you cover?
Yes, Fawley Bottom is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Will I get paperwork for my records?
Yes, always. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Do you handle baffle and mesh filters?
Baffle filters and mesh filters. Mention how many canopies you have when you get in touch and we will confirm it on site.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange won’t do:
- A fan that’s failing or too weak for the system
- Grease behind the filters that a swap cannot remove
- Grease already built up in the ductwork, which needs a full TR19 clean
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.
Parts of the system we cover
- Restaurants and pubs
- School and hospital kitchens
- Baffle filters
- Wall canopies
- Island canopies
- Mesh filters
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Clear anything stored on or near the canopy
- Report a dripping canopy early
- Tell us if the menu or opening hours change
- Do not refit a filter that’s bent
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.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule keeps everything on track.

Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
