Portchester: your questions answered
Do you work in villages like Portchester?
Yes. Villages and rural sites across the South East are part of our work, Portchester included. Just mention lanes, gates or anything else about the site when you book.
Who carries out food hygiene inspections in Portchester?
In Portchester, it’s Fareham council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What shows that the ducts need a clean?
A grease thickness test gives the answer. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). BESA guidance says the mean shouldn’t exceed 200 microns, and 500 or more anywhere needs immediate spot cleaning.
How long does ductwork cleaning take?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. Visits are planned out of hours.
What happens if there are not enough access panels?
Any section we can’t reach is recorded on the report, as TR19 expects. We can fit new access panels so they’re cleaned next time.
Do you install duct access panels?
Yes. The survey or clean shows where sections couldn’t be reached, and fitting them means future cleans are more complete.
How do you clean inside the ductwork?
Through access panels along the duct. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
What paperwork do you give after a duct clean?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, photos and any unreachable sections.
About our ductwork cleaning in Portchester
Grease in a duct is hidden, which is exactly why it’s dangerous. A flare-up drawn up from the range can light it, carrying a fire along the duct and into rooms far from the kitchen. Cleaning the duct takes that fuel away. We are often asked to deal with years of grease along the duct floor and a duct nobody has opened in years, on horizontal duct runs, attenuators and access panels.
In a smaller place like Portchester, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
The sign-off is always in writing: a written report, dated and illustrated with pictures, 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.

Kitchen extracts in Portchester
Sea air reaches Portchester, which sits within about 1 mile of the coast. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. The FSA’s food hygiene register shows about 39 restaurants, cafés and works canteens and about 19 takeaways in Portchester and the streets around it, up to about 1.5 miles out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Portchester sits within the area of Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run catering at a healthcare site, such as a hospital like Queen Alexandra Hospital about 2.3 miles east, the extract may need cleaning more often than a part-time kitchen. For schools such as Castle Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

How it works
The visit has three parts: set-up, the treatment itself and the sign-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 from a few hours to more than one visit, depending on duct length and access. Your opening hours decide when we come to Portchester, not ours.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Signs you need ductwork cleaning in Portchester
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, so duct runs keep collecting grease long after the canopy.
What we’re most often called out for:
- Stale grease odours from the duct
- A grease test showing the duct is overdue
- Fat dripping from the ductwork
- A duct nobody has opened in years
Where a hall near Church of St Mary, or anywhere in Portchester, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
What your quote should include
- If they look at the system before pricing
- Whether the whole system is included, or only the parts that are easy to reach
- What paperwork you get at the end
- How areas they cannot reach will be recorded
What affects the quote in Portchester
We don’t publish a price list, because sites vary so much. The quote depends on:
- The condition of the system
- Parking and loading at the site
- The times the site is available
- One-off work versus a regular cycle
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
What we need to know
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or send us an email.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Managing agents and facilities teams in Portchester
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
How the job changes from site to site
Multi-storey and shared buildings
In a building with several floors, the duct may pass other tenants’ spaces. Access is planned with the building’s managers, so the clean is done safely and quietly.
Horizontal duct runs
Grease settles on the floor of a flat duct run. We scrape out the heavy layer first, then the walls and roof are cleaned too.
Honest limits
Some problems need a different service or another trade:
- A duct that’s too small or badly routed for the kitchen (a design issue)
- An extract fan that has stopped working
- Fire dampers that do not close (they need testing and remedials)
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think.
