About our grease filter exchange in Sleapshyde
We run grease filter exchange for all kinds of kitchens in Sleapshyde, whether there’s one canopy or many. Visits can be timed around your service, so cooking is not interrupted. We’re often asked to deal with drips falling from the filters onto equipment and a greasy plenum behind the filters, on baffle filters, island canopies and mesh filters.
In a small place like Sleapshyde, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
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.

Why deal with it now?
Grease dripping from the canopy is a sign the filters cannot hold any more. Drips land on surfaces and equipment below, which an EHO may well notice. Rural sites can’t always move to another kitchen or room when something fails.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What you get with us
- Full insurance on every job
- Fixed quotes, usually within one working day
- Work around your opening hours, with 24/7 emergency cover

FAQs for Sleapshyde
Can the work in Sleapshyde be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Sleapshyde keeps running as normal. Tell us your opening hours when you ask for a quote.
Is Sleapshyde within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How long does grease filter exchange take?
Your quote will say how long we expect to be there. For a typical site, it takes anything from a few minutes to an hour or so, depending on the number of filters.
Does a filter exchange replace TR19 cleaning?
No. The rest of the system still collects grease at the right interval.
What happens to the dirty filters?
We take them away to be cleaned and your staff don’t have to deal with them. Clean filters go straight in.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Does the report say when we need you again?
Yes. The recommended date is on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.
Do you handle baffle and mesh filters?
We work with both baffle and mesh filters. We check what’s in your canopies first and plan the exchange around them.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes less than an hour in most kitchens, and we clear up before we go. We agree a date with you, plan the drive to Sleapshyde and turn up when the site is quiet.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
How to prepare
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet

How we price grease filter exchange
We quote each job individually. This is what makes a difference:
- The number of sites or systems
- The times the site is available
- How easy every part is to reach
- Where the site is and how we reach it
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.
Asking for a quote
What to send for a quote:
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Photos showing the whole system and its surroundings
- The postcode and the type of business
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, call 0345 646 2711, or email photos.
What staff can safely do
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.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Sleapshyde kitchens: local notes
Food Standards Agency records list about 35 restaurants, cafés and works canteens and about 13 takeaways within 1.5 miles or so of the middle of Sleapshyde. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. In Sleapshyde, food businesses are inspected by environmental health officers from St Albans City council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Sleapshyde falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Term dates shape school work: for a school like Colney Heath Junior Mixed Infant and Nursery School, an extract clean fits neatly into a half-term or summer break. If your kitchen is in a listed or historic building, like the houses around Sleapshyde (Hatfield House is about 2.5 miles north-east), fitting access panels needs care. If you run a church or community hall kitchen, near Church of St Mark or elsewhere in Sleapshyde, its extract still collects grease from every lunch and event.

For rail, the closest station is Welham Green station, roughly 2.4 miles east of the centre.

Keeping the system healthy
So the system stays in good health:
- Keep the extract on whenever the range is in use
- Do not let the full clean slip because filters are changed
- Keep canopy surfaces wiped down
- Look out for drips from the canopy
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease so tell us if you need a replacement.
Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.
Part by part
Busy restaurant and pub kitchens
When service is non-stop, filters get forgotten. An exchange service takes it off the rota.
Canopy filter housings
We check that filters sit snugly in the housing at each visit since a gap is a route for grease.
