Commercial kitchen extraction cleaning in Park Street
Duct Doctor has been cleaning kitchen extract systems since 2009. 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 fat running down the canopy edge and proof of cleaning requested by an insurer, on canopies and hoods, vertical risers and discharge points. Most calls from Park Street come after an insurer, an EHO or a fire officer asks to see the last TR19 certificate. We handle the clean and the paperwork in one visit.
The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, so that is where most of the work in Park Street goes.
For a kitchen in or near Park Street, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Common problems we fix in Park Street
Grease in an extract starts as vapour. As the air cools on its way through the duct, the fat condenses and sticks, and the layer grows a little with every meal cooked. Filters catch some of it, but never all.
These are the problems we see most often:
- A smoky, hot kitchen with weak extraction
- A TR19 certificate needed for the insurer
- An extract that has never been cleaned to TR19
- Stale cooking odours from the system
For kitchens close to Park Street station, where the day often starts early and ends late, the extract can be cleaned overnight.
Comparing quotes
- Whether they’re fully insured
- When they can work, and whether that is outside your opening hours
- Exactly which parts of the system are covered
- If they look at the system before pricing
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Keep the baffle filters clean
- Refit filters properly after cleaning
- Wipe the canopy down at the end of each day
- File each certificate with the fire risk assessment
When the clean is finished, grease readings are taken again at the same points, so you can see the difference in numbers as well as photos. Your TR19 certificate is then issued through the BESCA Vent Hygiene Elite portal.
Keep the outside of the canopy wiped and any grease cups emptied. It won’t replace a TR19 clean, but it slows what reaches the duct.
Managing agents and facilities teams in Park Street
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What the work involves, part by part
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, and measured readings show whether the minimum interval is enough.
Canopy and plenum
The plenum is out of sight behind the filters, so it’s easy to forget. We take the filters out and clean the plenum and housing thoroughly.
Questions from Park Street
Do you work at weekends in Park Street?
Yes, evening, overnight and weekend work is normal for us. That way a site in Park Street does not have to lose a day’s trading. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
Which fire service covers Park Street?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Park Street. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What does a TR19 kitchen extract clean include?
A TR19 Grease clean covers the full extract route, not just the canopy. That means canopy, plenum, filters, ducts, risers, fan and discharge, reached through access panels where necessary.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What paperwork comes with a kitchen extract clean?
You get both a certificate and a photo report. Keep them in the maintenance log with the fire risk assessment, ready for your insurer or an inspection.
How long does it take to clean a kitchen extract system?
A small kitchen with a short duct can be done in a few hours, while long runs and tall risers take longer and may need more than one visit. Your quote says how long to expect.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning doesn’t 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.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes one visit for most kitchens, while large or complex systems may need more than one. In a small place like Park Street, the journey is planned ahead and the visit arranged around the site’s hours.
- We start with a survey, so we know every part of the system before we quote.
- Set points are tested for grease thickness and the quote is fixed before we start.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- Finally the system is re-tested and photographed, and the certificate and report follow.
How to prepare
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after photos from each clean are a simple way to show the extract is in hand. Park Street is covered by Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
