About our ductwork cleaning in Speed Gate
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. We are often asked to deal with a rancid smell from the extract duct and grease leaking from duct joints, on horizontal duct runs, multi-storey ducts and access panels.
Work in a small place like Speed Gate starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Common questions in Speed Gate
Can you get to a site in Speed Gate?
Yes. Speed Gate is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Which fire authority looks after Speed Gate?
It’s Kent Fire and Rescue Service, which covers Speed Gate. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What’s the cleaning interval for extract ductwork?
It follows the same interval as the whole extract, from every 3 months for heavy use to every 12 months for light use. Grease thickness testing shows whether that’s often enough.
When is the ductwork cleaned?
We plan the clean when you are not cooking. Overnight and weekend work is common, so no service is lost.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
Keeping the system healthy
To keep the system working properly between visits:
- Leave a way through to the access panels
- Never cook with a filter missing
- Consider fitting panels where the report shows gaps
- Tell us if grease leaks from the ductwork
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Waste grease and water are taken away.
Extra access panels mean more of the duct gets cleaned each time. Grease you can reach is grease that gets removed.
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Managing agents and facilities teams in Speed Gate
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building around the people who use them.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
When to call us in Speed Gate
Risers carry the extract up through the building. Grease collects on the riser walls and gathers at the bottom, where it can pool. Panels along the riser make proper cleaning possible.
If you notice any of these, it’s worth a diagnosis:
- Proof of duct cleaning for the insurer
- Years of grease along the duct floor
- Grease pooling at the foot of the riser
- Grease seeping out of the duct seams
A hospital like Darent Valley Hospital, about 4.5 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
What to look for in a quote
- When they can work, and whether that is outside your opening hours
- Whether VAT is included
- Whether a survey comes first
- What happens if part of the system cannot be accessed
What ductwork cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning won’t do:
- Parts of the duct with no way in
- An extract fan that has stopped working
- A damper stuck open in the duct
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly.
What the work covers
- Bends and junctions
- Horizontal duct runs
- Attenuators
- Access panels
- Multi-storey ducts
- Vertical risers
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes anything from a few hours to several visits, depending on the length of duct. For a village or hamlet like Speed Gate, tell us about narrow lanes, gates and parking when you book.
- We map the duct route and check where the access panels are.
- Grease readings are taken at set points along the duct.
- Access panels are opened and heavy deposits scraped out by hand.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
- Move anything stored near the system
Ask for a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
