Duct cleaning in Shermanbury
For cleaning of kitchen extract ductwork, horizontal runs and vertical risers through access panels in Shermanbury, one call is all it takes: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- High readings at a recent grease test
- Heavy grease at the base of a riser
- A rancid smell from the extract duct
Different parts, different methods
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. Grease can collect there and stain the area around it, so it’s cleaned as far as safe access allows.
Access panels
We can fit new access panels where the duct needs them, making future cleans more complete. We’ll recommend where they should go.
About our ductwork cleaning in Shermanbury
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we can’t reach, so you know exactly where you stand. Common call-outs are for smells of old cooking grease from the ductwork and heavy grease at the base of a riser, across multi-storey ducts, attenuators and vertical risers.
Somewhere as small as Shermanbury, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What else we do in Shermanbury
Between visits
Good habits slow the build-up between visits. Our tips:
- Keep your cleaning records together
- Keep access panels clear of stored items
- Never cook with a filter missing
- Ask us about extra access panels where sections can’t be reached
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Waste grease and water are taken away.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.
What ductwork cleaning looks like in Shermanbury
The fire and rescue service for Shermanbury is West Sussex Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Shermanbury, food businesses are inspected by environmental health officers from Horsham council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens, like those at hospitals such as The Dene Hospital (about 5.2 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. Church and community hall kitchens, near The Parish Church of St Giles or anywhere around Shermanbury, are easy to forget, but their extracts collect grease like any other.

Why deal with it now?
BESA guidance says grease shouldn’t exceed a mean of 200 microns between cleans. A reading of 500 microns or more at any point means a spot clean right away. Leaving the duct makes those limits harder to keep to. In a place like Shermanbury, ductwork and fans are easy to forget until something goes wrong.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
Why us?
- In business since 2009
- A single point of contact for sites across the South East and London

- Fully insured
Take a look at what affects the cost and our accreditations.
What affects the cost of ductwork cleaning
Sites vary more than people expect. The main factors:
- The scale of the work
- Access, including roofs, risers and ceiling voids
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
What to send for a quote
There’s no need for technical detail. Just send:
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
If you need ductwork cleaning in Shermanbury, ring 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote typically follows within one working day.
What we’re called out for in Shermanbury
Grease filters that don’t seal let fat straight through. The duct then takes grease that the filters should have stopped, and build-up speeds up.
It’s time to book a visit if you see:
- Stale grease odours from the duct
- Readings above 200 microns from a grease thickness test
- Duct runs that can’t be reached
- Hardened, baked-on grease in long horizontal runs
Bursars and site managers at schools such as Jolesfield CofE Primary School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- When they can work, and whether that is outside your opening hours
- Whether the quote is based on a survey or photos
- What’s included in the scope, part by part
- If the quote is a fixed price or an estimate
The process
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the ductwork cleaning, clear away and leave you the report. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. We agree a date with you, plan the drive to Shermanbury and turn up when the site is quiet.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
How to prepare
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
- Mention any sign-in, permit or induction we need
Getting a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Shermanbury questions
Can you get to a site in Shermanbury?
Yes. Villages and rural sites across the South East are part of our work, Shermanbury included. Let us know about access, parking and anything unusual about getting there when you book.
Which fire service covers Shermanbury?
West Sussex Fire and Rescue Service is the fire and rescue service for Shermanbury. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How do you know if the ductwork needs cleaning?
Start with the date of the last clean. If it’s overdue, or there is not one, a clean is due, and grease readings will confirm how urgent it is.
What’s the cleaning interval for extract ductwork?
It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then phone us on 0345 646 2711 or drop us a line.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Staff cleaning versus specialist work
If your staff spot something 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’ll take a look and send you a fixed quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
