Commercial kitchen extraction cleaning in Kemprow
The part of the system nobody sees is often the dirtiest. We reach horizontal runs and vertical risers through access panels, removing thick grease by hand, then using degreasers, hot water or steam to suit the deposit. Any section we cannot reach is recorded on the report, and new panels can be fitted. If you have extraction mentioned at an environmental health visit and a smoky, hot kitchen with weak extraction, we can help. Searching for commercial kitchen extraction cleaning in Kemprow? We have been cleaning kitchen extracts across the South East since 2009, as a BESCA Vent Hygiene Elite member.
Each job starts with a look at where grease has built up: wet film or deposit thickness readings show which parts of the duct need the most attention, and the same readings after the clean show the result.
Somewhere as small as Kemprow, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Kemprow: your questions answered
Can the work in Kemprow be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Kemprow needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Who carries out food hygiene inspections in Kemprow?
That is Hertsmere council, whose environmental health officers carry out food hygiene inspections in Kemprow. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Are you a BESCA Vent Hygiene Elite member?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How much does kitchen extract cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Can you set up regular visits?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.

The process
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes a few hours for a small kitchen, longer for a large system. If the van will struggle with a lane or gateway near Kemprow, let us know and we’ll plan around it.
- First the diagnosis: a survey of the whole system and its access points.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Why act early in Kemprow
A clogged extract doesn’t only raise the fire risk. Blocked filters and narrowed ducts slow the airflow, leaving the kitchen hot and smoky, while the fan works harder to move less air. Grease drips, smells and condensation are common next. Out of sight is the usual reason a rural system goes too long without attention.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

Kitchen extract cleaning in Kemprow: the local picture
According to Food Standards Agency records, there are about 8 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses across Kemprow and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Kemprow get their food hygiene inspections from Hertsmere council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Kemprow sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hospital like Shenley Hospital, about 2.3 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 2.7 miles north-west), access may need planning.
Kemprow is about 3 miles north of Bushey, in Hertfordshire. We provide kitchen extract cleaning for commercial premises of every kind in Kemprow and the rest of Hertfordshire. Our area takes in 381 places across Hertfordshire, large and small. There’s also a page for London, about 16 miles away.

What the work involves, part by part
Extract fan and discharge
Some systems have attenuators to cut noise, and they hold grease. Where they can be cleaned, they are, and the report notes anything that cannot.
Ductwork and risers
Grease builds up most where the duct turns. We test at points like these before and after cleaning, so the report shows the difference.
Managing agents and facilities teams in Kemprow
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Signs you need kitchen extract cleaning in Kemprow
In Kemprow, as anywhere, grease gathers where the air slows down: in long flat runs, at bends and changes of direction, and in the fan housing. Cooler sections of duct collect the most.
The symptoms we are asked about most include:
- Ductwork thick with old, hardened grease
- Poor airflow at the canopy
- Grease drips onto cooking equipment
- Grease smells coming from the extract
If you look after a school kitchen, at a school such as Fair Field Junior School or anywhere near Kemprow, the holidays are the usual time for a TR19® clean.
What to look for in a quote
- What’s included in the scope, part by part
- Proof of insurance
- Whether the price is fixed
- When they can work, and whether that’s outside your opening hours
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Day-to-day cleaning is something your team can do: 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, and that is where we come in.
What affects the quote in Kemprow
We do not publish a price list, because no two systems are the same. What we look at:
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- The number of sites or systems
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
To get a fixed quote, phone us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
