Ductwork cleaning in Netley, Hampshire
Our technicians work in Netley on ductwork cleaning. Out-of-hours visits, a fixed quote and a written report with pictures on every job.

How we handle ductwork cleaning in Netley
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it, and that’s where a kitchen fire can travel. We clean it from the inside, through access panels, to BESA TR19® Grease. If you have a grease test showing the duct is overdue and a rancid smell from the extract duct, we can put it right, from horizontal duct runs, attenuators and bends and junctions onwards.
Size doesn’t change the work: a kitchen in a place like Netley gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Ask us about extra access panels where sections can’t be reached
- Ask for a grease thickness test if the kitchen gets busier
- Do not switch the extract off early
- Keep your cleaning records together
Keep the certificate and report with the fire risk assessment. An insurer, fire officer or EHO may ask to see it, and the pictures make the duct’s condition easy to see.
The less grease gets past the canopy, the cleaner the duct stays. Clean, properly seated filters are the duct’s best protection.
When to call us in Netley
A vertical riser can run up several floors. Grease collects on the riser walls and gathers at the bottom, where it can pool. Access along its height is needed to clean it properly.
These are the problems we see most often:
- Ductwork that has never been cleaned
- High readings at a recent grease test
- Gaps where access panels were never fitted
- Stale grease odours from the duct
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Netley is Coldeast, about 2.8 miles east.

Leave it or put it right?
A fire in a greasy duct is hard to reach and hard to stop. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, which is why the duct matters as much as the canopy. Light use slows the build-up but doesn’t stop it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What you get with us
- Fully insured
- A fixed price before any work starts

Ductwork cleaning in Netley: the local picture
Netley is within about 1 mile of the coast. Corrosion on the fan housing and cowl is worth a look at every clean, alongside the grease. There are about 22 restaurants, cafés and canteens and about 15 takeaways within 1.5 miles or so of the middle of Netley, according to the Food Standards Agency’s register. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Kitchens in Netley get their food hygiene inspections from Eastleigh council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
If you look after a school kitchen, at a school such as Netley Abbey Infant School or anywhere near Netley, the holidays are the usual time for a TR19® clean. For kitchens close to Netley station, where the day often starts early and ends late, the extract can be cleaned overnight.
Netley is about 3 miles north-east of Hythe, in Hampshire. Whether your site is in the middle of Netley or further out, ductwork cleaning is available to all kinds of commercial premises, from a single unit to a large public building.

Netley questions
Which environmental health team covers Netley?
That’s Eastleigh council, whose environmental health officers carry out food hygiene inspections in Netley. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Which fire authority looks after Netley?
Netley 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.
How long does it take to clean extract ducts?
A short duct can be cleaned in a few hours, while long ducts and tall risers can need more than one visit. We plan the work around your kitchen.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What’s involved in cleaning extract ducts?
Each section is cleaned through its own panel. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
How can I tell if my extract ducts are dirty?
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.
Do you cover Netley?
Yes. We work in Netley and across Hampshire, as part of our work across South East England and London. To book, phone us on 0345 646 2711 or use the quote form.

- Access panels
- Bends and junctions
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
The process
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 work takes anything from a few hours to several visits, depending on the length of duct. Everything the job in Netley needs is worked out beforehand, from the survey.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, pictures and a next clean date.
Before we arrive
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.
