In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
How we handle kitchen extract cleaning in Stone
We have been trading since 2009, cleaning kitchen extracts across the South East and London. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. Common call-outs are for poor airflow at the canopy and fat running down the canopy edge, on horizontal duct runs, plenums and filters and canopies and hoods. Searching for commercial kitchen extraction cleaning in Stone? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
A kitchen running fryers and chargrills all day builds up grease much faster than one that mostly steams and boils, so we look at the menu as well as the opening hours when we suggest the next date.
In a smaller place like Stone, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Grease, kitchens and Stone
The FSA’s data shows about 12 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses registered in Stone and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for Stone is Kent 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 Stone get their food hygiene inspections from Dartford council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
Commuter trade near Stone Crossing station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. If you run a church or community hall kitchen, near Church of St Mary or elsewhere in Stone, its extract still collects grease from every lunch and event. School kitchens, at schools like Stone St Mary's CofE Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Different parts, different methods
Grease filters
A filter that is missing or bent lets grease straight past. We check they fit as they should when we refit them, and flag any that don’t.
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, so grease readings help set the right interval.
Towns and villages near Stone

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Switch the fan on before cooking starts
- Make sure every filter is fitted before cooking
- Wash or exchange the filters often
- Give the canopy a daily wipe
The certificate records when the clean was done, where and by whom. Keep it in the maintenance log with your fire risk assessment so it’s ready when anyone asks to see it.
Clean the grease filters often, not just on clean day. Clean, well-fitted filters catch more fat before it reaches the duct, which slows build-up further down the system.
What we do, step by step
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from a few hours to a full night, depending on the size of the system. Visits to a place like Stone are planned ahead, so we arrive with what the survey says the job needs.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- We arrive after close, protect the area and contain the waste.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
How to prepare
- Let us know about parking and loading

Common questions in Stone
Will you come out to Stone?
Yes, we work in villages as well as towns, and Stone is covered. Just mention lanes, gates or anything else about the site when you book.
Which fire authority looks after Stone?
Fire safety enforcement in Stone is handled by Kent Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What types of premises do you cover?

What about areas you can’t get to?

Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
What does a TR19 kitchen extract clean include?
Every part the air passes through, as far as access allows. Sections with no access are listed on the report, and extra panels can be fitted.
Will my insurer ask for a TR19 certificate?
Extract grease is fuel for a kitchen fire, which is why many insurers require TR19 cleaning. Our certificate and photo report give you that evidence.

Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
