Ductwork Cleaning in Brasted
Ductwork cleaning for Brasted, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Years of grease along the duct floor
- Duct runs that cannot be reached
- Thick deposits at the bottom of a vertical duct
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Check readings when the menu changes
- Book the next clean before the recommended date
- Keep your cleaning records together
- Keep the fan on while anything is cooking
Every panel we open is refitted when we finish, and the surrounding area is left clean. Waste grease and water are taken away.
Grease that never reaches the duct never needs cleaning out of it. Keep the filters clean, well fitted and in place whenever you cook.
About our ductwork cleaning in Brasted
No two duct runs are the same, in Brasted or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route and finds every access point before we quote. We are often asked to deal with heavy grease at the base of a riser and years of grease along the duct floor, on vertical risers, access panels and multi-storey ducts.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Brasted, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Brasted kitchens: local notes
There are about 15 restaurants, cafés and works canteens and about 3 takeaways within about 1.5 miles of central Brasted, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. London jobs normally start after the last service, with loading and roof access agreed with the building first. Kitchens in Brasted get their food hygiene inspections from Sevenoaks council. 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.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Tandridge Priory is the nearest hospital to Brasted, about 3.8 miles south-west. Quebec House, about 1.5 miles south-west, is one of the historic houses near Brasted; if you run event catering at a venue like that, cleans can be booked between functions.

What the work involves, part by part
Bends and transitions
Grease tends to pile up at elbows. It’s scraped out and degreased, and readings are taken there before and after.
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.
Do you need ductwork cleaning in Brasted?
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Any of these means the system needs a check-up:
- Gaps where access panels were never fitted
- A grease test showing the duct is overdue
- Duct runs with no cleaning record
- Thick deposits at the bottom of a vertical duct
If you run a church or community hall kitchen, near Church of St Martin or elsewhere in Brasted, its extract still collects grease from every lunch and event.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Brasted: your questions answered
Can the work in Brasted be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Brasted keeps running as normal. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Which fire service covers Brasted?
Fire safety enforcement in Brasted is handled by London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do we need to close while you work?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What’s involved in cleaning extract ducts?
We survey the route, test the grease, then open the access panels. Each run and riser is scraped and degreased, and test again when we’re done.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Are you accredited?
We are 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.
Leave it or put it right?
A dirty duct is something insurers ask about. Many policies require TR19 cleaning, and a claim may be refused or reduced without evidence. Your certificate and photo report show the ducts were cleaned. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes a few hours for a short run, longer for long runs and tall risers. Before any visit in Brasted, we agree where the van can stop and how equipment reaches the system.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Before we arrive
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Have your last certificate or report to hand
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
