How the job changes from site to site
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and test it before and after.
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. Access is planned with the building’s managers, so the clean is done safely and quietly.
How we handle ductwork cleaning in Waltham St Lawrence
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers attenuators, multi-storey ducts and vertical risers, and the jobs we see most are duct runs that can’t be reached and grease leaking from duct joints.
In a village or hamlet like Waltham St Lawrence, the kitchens that need extract cleaning are usually 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.
Duct Doctor has been trading since 2009, and we’re 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.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Keep to the interval on the report
- Get panels fitted where the duct couldn’t be cleaned
- Report any grease dripping from duct joints
- Never cook with a filter missing
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Book the next duct clean before the date passes. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Common problems we fix in Waltham St Lawrence
A greasy duct is a fire path, in Waltham St Lawrence as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Any of these means the system needs a check-up:
- A rancid smell from the extract duct
- Duct runs that can’t be reached
- A grease test showing the duct is overdue
- A duct nobody has opened in years
If you look after a school kitchen, at a school such as Waltham St Lawrence Primary School or anywhere near Waltham St Lawrence, the holidays are the usual time for a TR19® clean.

Waltham St Lawrence questions
Which environmental health team covers Waltham St Lawrence?
The local authority for Waltham St Lawrence is Windsor and Maidenhead council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Waltham St Lawrence?
It’s Royal Berkshire Fire and Rescue Service, which covers Waltham St Lawrence. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
How often does extract ductwork need cleaning?
BESA guidance sets minimum intervals by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease sets the real interval.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Do you install duct access panels?
Yes, we do. We will point out where panels are needed, and we can fit them so those sections are cleaned in future.
What paperwork do you give after a duct clean?
Every clean comes with a photo report, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.

Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do.

- Ductwork that was poorly designed
- An extract fan that has stopped working
- Duct sections that need replacing
