Grease filter exchange in Andover, done properly
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled straight away. If you’re dealing with gaps where filters have been removed and filters so greasy the air can barely pass, we can help.
Most kitchens in a town like Andover cannot close for a day, so the work is done after service, overnight or on a closed day. The kitchen is handed back clean and ready to cook.
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 carry full insurance.

Signs you need grease filter exchange in Andover
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up, so it needs more frequent changes.
Most sites get in touch after spotting something like this:
- Grease left in baffles after washing
- Blocked baffle filters
- Damaged filters letting grease past
- Drips falling from the filters onto equipment
A hospital like Andover War Memorial Hospital, about 0.7 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before booking
- Whether the price is fixed
- When they can work, and whether that’s outside your opening hours
- Whether they’re fully insured
- How they set the interval to the next visit
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Do not let the full clean slip because filters are changed
- Keep canopy surfaces wiped down
- Mention it if the kitchen gets busier
- Never leave gaps in the filter bank
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner between full cleans.
Why act early in Andover
For any kitchen in Andover, filters can’t stand in for a full TR19 clean. But clean filters do help the system between cleans, and that shows when the next clean comes round. In a town like Andover, a problem caught early is a planned visit, not an emergency.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Questions from Andover
Can school kitchens in Andover be cleaned in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 15 schools, colleges and universities with registered kitchens within about a mile and a half of Andover. Just call us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Which council inspects kitchens in Andover?
Kitchens in Andover are inspected by Test Valley council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you clean our existing filters instead?
Yes, filter cleaning is available. The first step is looking at the filters you have because bent or damaged ones may need replacing.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Does a filter exchange disrupt service?
An exchange doesn’t take long, and we can come before or after service. The clean set goes in as soon as the dirty one comes out.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a dated report with pictures, listing the work and any areas we couldn’t reach.

Fixed quotes for grease filter exchange in Andover
Before we fix a price, we need to know a few things. We check:
- The times the site is available
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
What to send for a quote
We can often survey from pictures. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You will usually have a quote within one working day.
How the visit works
There are three stages on the day: 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 photos. Most of the time goes on the work itself, and that takes well under an hour for most canopies. Three things shape a visit in Andover: when you are closed, where we can park and how we get to the system.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- At each visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
- Let us know about parking and loading
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

For schools such as St John the Baptist Catholic Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Different parts, different methods
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
The plenum
Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.
