Your questions about ductwork cleaning in Preston
Can you work in Preston outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Preston needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
How do you handle parking and loading in Preston?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
What shows that the ducts need a clean?
Drips, smells and weak extraction are clues, but the only sure way is to measure. Grease thickness testing shows exactly where the duct stands.
Can you fit access panels in our ductwork?
Yes, we do. The survey or clean shows where sections couldn’t be reached, and we can fit them so those sections are cleaned in future.
Will I get a report after the ducts are cleaned?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. The report shows readings, photos and any sections we couldn’t reach.
How is kitchen extract ductwork cleaned?
We open each access panel and clean the section it reaches. Grease is scraped out first, then degreased, with readings taken before and after.
Ductwork cleaning in Preston
No two duct runs are the same, in Preston or anywhere else. A few metres to an outside wall, or a riser up through the building to a roof fan. We map the route during the survey and finds every access point before we quote. The work covers attenuators, vertical risers and bends and junctions, and common reasons people get in touch are hardened, baked-on grease in long horizontal runs and heavy grease at the base of a riser.
In London, few kitchens can spare a day to close, so work in Preston is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Duct Doctor has been trading since 2009, as 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.

Ductwork cleaning around Preston
According to Food Standards Agency records, there are about 27 pubs and bars and about 6 hotels and B&Bs in Preston and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Most London extract cleaning happens at night, after the last service. The fire and rescue service for Preston is London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run a café or takeaway near South Kenton station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Bursars and site managers at schools such as Preston Park Primary School tend to book extract cleaning for when the kitchen is empty.

Signs you need ductwork cleaning in Preston
Grease in a duct running from a kitchen in Preston is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Signs it’s time to call us include:
- Duct runs that cannot be reached
- An insurer asking for TR19 evidence
- High readings at a recent grease test
- Smells of old cooking grease from the ductwork
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Preston is St. Mark's Hospital, about 1.1 miles west.
Questions to ask before you book
- Whether a written report and pictures are included
- Whether the quote is based on a survey or pictures
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How VAT is shown on the quote
Different parts, different methods
Access panels
Access panels are the doors that let us into the duct. Without them, parts of the duct cannot be reached and the report has to say so.
Horizontal duct runs
Grease settles on the floor of a flat duct run. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
How we price ductwork cleaning
The quote reflects the site in front of us. We consider:
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
- The condition of the system
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What we need to know
Many jobs can be priced from photos and some basics. Send what you can of the following:
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
When it’s something else
To be straight with you, some problems need a different fix:
- Undersized or badly laid-out ducts
- A damper stuck open in the duct
- Duct sections that need replacing
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly before you book.
What we work on in Preston
- Bends and junctions
- Multi-storey ducts
- Horizontal duct runs
- Vertical risers
- Access panels
- Attenuators
How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. Loading bays, visitor permits and roof access are the first things we ask about for a site in Preston.
- 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.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Report any grease dripping from duct joints
- Keep the fan on while anything is cooking
- Never cook with a filter missing
- Keep your cleaning records together
Any section of duct we couldn’t reach is listed on the report and why. We can fit access panels so those sections are cleaned next time.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.

What else we do in Preston
Why deal with it now?
There’s no law that names TR19. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and grease in the duct is part of that. A building in Preston may have flats or offices above and alongside, and a fault in the system can affect them too.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
