Ductwork cleaning in Clayhall, done properly
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Grease settles along every metre of it and a fire in the duct can spread through the building. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. If you have heavy grease at the base of a riser and grease leaking from duct joints, we can help.
Around a smaller place like Clayhall, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Your questions about ductwork cleaning in Clayhall
Which environmental health team covers Clayhall?
That is Gosport council, whose environmental health officers carry out food hygiene inspections in Clayhall. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Which fire service covers Clayhall?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Clayhall. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work in Clayhall?
Yes. Our area takes in London and the counties of South East England, and that includes Clayhall.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
How often does extract ductwork need cleaning?
It follows the same interval as the whole extract, ranging from 3-monthly to 12-monthly. Readings tell you if it needs to be more often.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What happens if there aren’t enough access panels?
Any section we can’t reach is recorded on the report, in line with TR19. New panels can be fitted to reach them in future.
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.
What affects the cost of ductwork cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the system
- Site rules, permits and inductions
- What state the system is in
- Whether we need access equipment or extra panels
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or send details by email, and we will talk you through it.
What to send for a quote
When you call or email, these details help:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Common problems we fix in Clayhall
A greasy duct is a fire path, in Clayhall as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
Keep an eye out for any of the following:
- Heavy grease at the base of a riser
- A grease test showing the duct is overdue
- A duct clean needed for an insurer
- A duct nobody has opened in years
For schools such as Haselworth Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Questions to ask before you book
- What insurance they carry
- Whether inaccessible sections are listed on the report
- Whether the work can be done while the site is closed
- What records you will receive afterwards
Why act early in Clayhall
A fire in a greasy duct is hard to reach and hard to stop. It can travel through the ductwork to other parts of the building, which is why the duct matters as much as the canopy. You choose the date of a planned visit, and a breakdown never asks.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

Aftercare tips
To keep the system working properly between visits:
- File each certificate and photo report in the maintenance log
- Flag drips from the duct right away
- Never cook with a filter missing
- Ask us about extra access panels where sections cannot be reached
Grease readings are taken again at the same set points, giving you before and after readings. Photos of each section go alongside them.
Have access panels fitted where sections cannot be reached. It doesn’t stop grease forming, but it stops it building unseen.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes from a few hours to more than one visit, depending on duct length and access. For a place like Clayhall, we load the van from the survey notes so the work can be done in one visit where possible.
- 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, photos and a next clean date.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system
- Move anything stored near the system
Getting a quote
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A failed fan motor at the end of the duct (a fan repair job)
- Leaking duct joints that need repair
- Faulty fire dampers
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.

- Access panels
- Multi-storey ducts
- Attenuators

What ductwork cleaning looks like in Clayhall
Clayhall lies within about 1 mile of the sea. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. The FSA’s food hygiene register shows about 64 restaurants, cafés and canteens and about 24 sandwich bars and takeaways within about 1.5 miles of central Clayhall. The duct above a busy canopy coats itself in grease long before anyone sees it. In Clayhall, food businesses are inspected by environmental health officers from Gosport council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
A hospital like Gosport War Memorial Hospital, about 1 mile north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Volunteers running a hall kitchen near St Francis, or anywhere in Clayhall, may not know when the extract was last cleaned, and a grease test settles it.
