Our grease filter exchange service in Hertfordshire

Whether your canopy has baffle or mesh filters, they load up with grease. Clogged filters choke the airflow and the extract struggles. Regular exchange keeps the air moving. The work covers restaurants and pubs, wall canopies and school and hospital kitchens, and common reasons people get in touch are a canopy running with filters missing and blocked baffle filters.

Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes well under an hour for most canopies.

We start by noting how many filters you have and what type they are.
A change schedule is agreed to match the kitchen’s cooking hours.
Each visit starts with the used filters being removed.
We fit clean filters and check they sit snugly in the housing.
Anything we notice, such as bent filters or a dirty plenum, is pointed out.

Pricing in Hertfordshire

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Grease filter exchange across Hertfordshire: local notes

From Watford, Hemel Hempstead and Stevenage to its smaller places, Hertfordshire has kitchens of every size. Every one gets the same full TR19® clean, from the canopy to the discharge.

From central London kitchens to coastal hotels and country pubs, London and the South East have every kind of site. The same TR19® standard applies to all of them, in Hertfordshire and beyond.

Watford: If you look after a school kitchen, at a school such as Watford St John's Church of England Primary School or anywhere near Watford, the holidays are the usual time for a TR19® clean. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Watford General Hospital is the nearest hospital to Watford, about 1.1 miles south.

What your team can do, and what needs us

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

What the work involves, part by part

Busy restaurant and pub kitchens

In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.

School, care home and staff kitchens

Visits can be planned around holidays and quieter periods so the filters are clean when cooking picks up.

Signs you need grease filter exchange

However long the kitchen cooks each day, the filters see every minute of it. A kitchen that cooks all day loads its filters quickly, so it needs more frequent changes.

Keep an eye out for these warning signs:

Filters that come out of the sink still dirty
A canopy that drips grease
Staff short of time to wash filters
Bent or damaged filters that don’t sit properly

Why act early?

Grease dripping from the canopy is a sign the filters cannot hold any more. Left, it ends up on equipment, food areas and staff, which an EHO may well notice.

Managing agents and facilities teams in Hertfordshire

Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

Hertfordshire: your questions answered

Will I get paperwork for my records?

Yes. It’s your proof that the work was done: a dated report with photos, listing the work and any areas we couldn’t reach.

Do we need to close the kitchen while filters are changed?

An exchange doesn’t take long, and can be booked outside service times. The clean set goes in as soon as the dirty one comes out.

Can we skip TR19 cleans if the filters are changed regularly?

No. Some grease passes the filters as vapour and settles in the ducts and the whole system still needs its TR19 clean.

Which sectors do you work in?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

Do you handle baffle and mesh filters?

Baffle filters and mesh filters. Tell us what you have when you give us a ring on 0345 646 2711 or email us and we’ll confirm it on site.

What accreditations do you have?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How long does grease filter exchange take?

On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Larger systems naturally take longer, and the quote will say how long.
