Ductwork cleaning in Preston, Hertfordshire

Ductwork cleaning in Preston, done properly
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. If you are dealing with thick deposits at the bottom of a vertical duct and grease seeping out of the duct seams, we can put it right, from multi-storey ducts, vertical risers and horizontal duct runs onwards.
Work in a small place like Preston starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Leave it or put it right?
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. A certificate that covers the ductwork is what they want to see. Rural sites cannot always move to another kitchen or room when something fails.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

Managing agents and facilities teams in Preston
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
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 can quote for the whole system.
Between visits
Aftercare is simple, and it makes the next visit easier:
- Consider fitting panels where the report shows gaps
- Don’t switch the extract off early
- Book the next clean before the recommended date
- Leave a way through to the access panels
The report names every part of the duct that couldn’t be reached, with the reason. We can fit access panels so those sections are cleaned next time.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
What a clean will not put right
Not every problem is solved by ductwork cleaning, and we’ll tell you before work begins. It won’t put right:
- Fire dampers that don’t close (they need testing and remedials)
- A failed fan motor at the end of the duct (a fan repair job)
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
If in doubt, call us on 0345 646 2711, or send details by email and we’ll say what we think before you book.

FAQs for Preston
Who is the fire and rescue service for Preston?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Preston. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Is Preston within the area you cover?
Yes. Preston is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How often does extract ductwork need cleaning?
The minimum depends on how long the kitchen cooks each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings may show it needs doing sooner.
How long does it take to clean extract ducts?
It depends on the length of the duct, the number of access panels and how much grease there is. Typically it takes a few hours for a short run, longer for long runs and tall risers.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
What ductwork cleaning looks like in Preston
The Food Standards Agency lists about 4 bars, pubs and nightclubs as registered food businesses within 1.5 miles or so of the middle of Preston. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Preston is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s North Hertfordshire council that sends environmental health officers to food businesses in Preston. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
Historic houses near Preston, such as Knebworth House about 3.9 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. A hall kitchen that only cooks for events, whether near Church of St Martin or elsewhere in Preston, still needs its extract cleaned, just less often. For schools such as Preston Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

What affects the quote in Preston
The price is fixed before any work begins. It takes into account:
- The scale of the work
- The times the site is available
- Whether several sites go on one quote
- Travel, parking and unloading
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
What to send for a quote:
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
The quickest way to a quote is to send pictures: 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.
How the visit works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours to more than one visit, depending on duct length and access. A quick note on how to find the site and where to park makes a visit to Preston run smoothly.
- We map the duct route and check where the access panels are.
- Grease readings are taken at set points along the duct.
- Through the access panels, thick grease is removed by hand first.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
How to get a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
