Ductwork cleaning for kitchens and businesses in Alton
No two duct runs are the same, in Alton or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey, so we know where to get in and how long it will take. If you are dealing with grease seeping out of the duct seams and a duct clean needed for an insurer, we can put it right.
For a pub, café or restaurant in a town like Alton, losing a day’s trade to cleaning is not an option, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Alton
The survey tells us what the work involves. The main factors are:
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- Parking and loading at the site
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- A few general shots of the system
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call us on 0345 646 2711, or email photos.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
When something else is needed
To be straight with you, there are a few things this work won’t fix:
- A duct that is too small or badly routed for the kitchen (a design issue)
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Fire dampers that don’t close (they need testing and remedials)
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think.

FAQs for Alton
Which environmental health team covers Alton?
The local authority for Alton is East Hampshire council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Who enforces fire safety at workplaces in Alton?
Alton is in the area of Hampshire and Isle of Wight Fire and Rescue Service. 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.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How do you know if the ductwork needs cleaning?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
What information do you need?
Some pictures and a quick description of the system plus the address and your hours. We will ask for anything else we need.
Can you quote from pictures?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How long does it take to clean extract ducts?
Duct length, access and grease levels all affect it. Typically it takes a few hours for a short run, longer for long runs and tall risers.
Managing agents and facilities teams in Alton
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a few hours for a short run, longer for long runs and tall risers. Three things shape a visit in Alton: when you’re closed, where we can park and how we get to the system.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
- Tell us about site rules, permits or sign-in
Getting a quote
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 work begins.

Alton kitchens: local notes
The FSA’s food hygiene register includes about 19 pubs, bars and clubs and about 3 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Alton. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Food hygiene inspections in Alton are the job of East Hampshire council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Alton falls to Hampshire and Isle of Wight Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Church and community hall kitchens, near Church of St Lawrence or anywhere around Alton, are easy to forget, but their extracts collect grease like any other.

What else we do in Alton
Between visits
So the system stays in good health:
- Diarise the next duct clean
- Don’t switch the extract off early
- Keep access panels clear of stored items
- Have the grease measured if cooking hours go up
Grease readings are taken again at the same set points, so the report shows the before and after figures. Photos of each section go alongside them.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
Different parts, different methods
Bends and transitions
A bend can hold far more grease than a straight run of the same length. 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.
