Grease filter exchange for kitchens and businesses in Long Marston
We set up grease filter exchange for kitchens in Long Marston on a schedule that suits their cooking. Busy kitchens need changes more often while a lighter kitchen can go longer. We agree the interval with you at the start. The work covers wall canopies, restaurants and pubs and mesh filters, and common reasons people get in touch are a greasy plenum behind the filters and missing filters in the filter bank.
Work in a small place like Long Marston starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
When it’s something else
Some problems need a different service or another trade:
- A canopy too small for the cooking beneath it
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Cooking smells reaching neighbours, which need odour control
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.

FAQs for Long Marston
Which fire service covers Long Marston?
Long Marston is in the area of Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you work overnight in Long Marston?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Long Marston needn’t be disturbed. Just give us a ring on 0345 646 2711 or email us with your opening times and we’ll plan around them.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
What accreditations do you have?
Duct Doctor is 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.
What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Signs you need grease filter exchange in Long Marston
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.
Keep an eye out for any of the following:
- Grease building up behind the canopy filters
- A canopy running with filters missing
- Weak extraction at the canopy
- Filters left unwashed on busy weeks
If you run a church or community hall kitchen, near Church of All Saints (Church of England) or elsewhere in Long Marston, its extract still collects grease from every lunch and event.

Different parts, different methods
The plenum
Clean filters reduce the grease reaching the plenum, but it still needs cleaning as part of TR19.
Baffle filters
Baffle filters are a common choice for commercial canopies. They don’t clean themselves, because the grease they collect builds up.
What grease filter exchange looks like in Long Marston
The FSA’s data shows about 3 bars, pubs and nightclubs registered within about 1.5 miles of central Long Marston. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Long Marston falls to Hertfordshire 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. Kitchens in Long Marston get their food hygiene inspections from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
If you run catering at a historic house or estate in the area (Ascott House is about 4.3 miles north), event kitchens in older buildings often have awkward duct runs that need planning. School kitchens, at schools like Long Marston VA Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost.
