How we price ductwork cleaning
A fixed price needs a few facts first. We look at:
- The number of sites or systems
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
- How easy every part is to reach
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Helping us quote
To speed up the quote, please include:
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business

Ductwork cleaning for kitchens and businesses in St Mary Cray
Each extract duct we take on in St Mary Cray goes through the full routine: we test the grease first, remove thick deposits by hand and degrease what’s left. Readings are taken again afterwards and pictures go into your report. If you are dealing with gaps where access panels were never fitted and a duct nobody has opened in years, we can put it right.
Kitchens in St Mary Cray, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Managing agents and facilities teams in St Mary Cray
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Kitchen extracts in St Mary Cray
Food Standards Agency data counts about 85 cafés, restaurants and staff canteens and about 56 sandwich bars and takeaways in St Mary Cray and the streets around it, up to about 1.5 miles out. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. The fire and rescue service for St Mary Cray is London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to St Mary Cray is Queen Mary's Hospital, about 1.9 miles north. If you run a church or community hall kitchen, near Church of St Mary or elsewhere in St Mary Cray, its extract still collects grease from every lunch and event.

St Mary Cray: your questions answered
Can school kitchens in St Mary Cray be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of St Mary Cray. Just call 0345 646 2711 or send us an email with your term dates and we will plan around them.
Which environmental health team covers St Mary Cray?
That is Bromley council, whose environmental health officers carry out food hygiene inspections in St Mary Cray. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
How long does ductwork cleaning take?
Duct length, access and grease levels all affect it. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.
What should I send you?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
What we are called out for in St Mary Cray
Many ducts don’t have enough access panels. Sections between panels go uncleaned, sometimes since the system was installed, and the grease there keeps building out of sight.
What we are most often called out for:
- Ductwork that has never been cleaned
- A duct clean needed for an insurer
- Grease seeping out of the duct seams
- Smells of old cooking grease from the ductwork
Term dates shape school work: for a school like Poverest Primary School, an extract clean fits neatly into a half-term or summer break.
Questions to ask before you book
- What insurance they carry
- Whether a survey comes first
- When the next visit should be, and why
- Which accreditations they hold, and whether you can check them
What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a shift or more, depending on the length of the runs and the number of access points. In a London area like St Mary Cray, parking, loading and building access are planned before the day of the work.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Preparing for the visit
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
Advice
Different parts, different methods
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Vertical risers
Cleaning a riser needs access along its height. Any part that can’t be safely reached is recorded.
Why act early in St Mary Cray
Grease left in a duct in St Mary Cray hardens over time. It bakes into a hard layer that takes far longer to remove, which makes each delayed clean a bigger one. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What ductwork cleaning can’t fix
Not every problem is solved by ductwork cleaning, and we’ll tell you before any work starts. It won’t put right:
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- A failed fan motor at the end of the duct (a fan repair job)
- Parts of the duct with no way in
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer.
