Ductwork cleaning in Sydenham, done properly
Not sure when the ductwork was last cleaned? Tell us about the system when you ring 0345 646 2711 or drop us a line, and a fixed price will follow, typically within one working day. If you are dealing with gaps where access panels were never fitted and a duct nobody has opened in years, we can help, from attenuators, horizontal duct runs and multi-storey ducts onwards.
In a small place like Sydenham, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
How the visit works
Each visit runs to the same pattern: protect the area, make the system safe, carry out the ductwork cleaning, tidy up and hand over the paperwork. On site, the work takes a shift or more, depending on the length of the runs and the number of access points. Pictures of the system and its access let us plan the work in Sydenham before we set off.
- We start by working out how the duct runs and where it can be opened.
- Set points along the runs are tested for grease.
- Through the access panels, thick grease is removed by hand first.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
Preparing for the visit
- Let us know about permits to work or site inductions
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive

Advice
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Store the certificate with the fire risk assessment
- Consider fitting panels where the report shows gaps
- Keep access panels clear of stored items
- Run the extract fan throughout service
The report gives a recommended next clean date, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Watch for warning signs between cleans: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.
Why deal with it now?
A partly blocked duct slows the airflow. Less air moves, so heat and smoke stay in the kitchen while the fan strains, and grease may start to leak from joints. If the system at a site near Sydenham fails, there may be nowhere nearby to move to.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

Do you need ductwork cleaning in Sydenham?
Grease filters that don’t seal let fat straight through. More grease reaches the ductwork than it should, and build-up speeds up.
What we’re most often called out for:
- Proof of duct cleaning for the insurer
- Readings above 200 microns from a grease thickness test
- Grease leaking from duct joints
- Sections of duct with no access panels
If you run a church or community hall kitchen, near Church of St Mary or elsewhere in Sydenham, its extract still collects grease from every lunch and event.
What your quote should include
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When they can work, and whether that is outside your opening hours
- If they look at the system before pricing
- Whether they’re fully insured
What affects the cost of ductwork cleaning
Sites vary more than people expect. What affects the quote:
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- A few general shots of the system
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
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, the quote is fixed before any work is booked.
Other services in Sydenham
Ductwork cleaning around Sydenham
Food Standards Agency records list about 4 restaurants, cafés and works canteens in Sydenham 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. Oxfordshire Fire and Rescue Service covers Sydenham. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from South Oxfordshire council inspect food businesses in Sydenham. 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.
If you run catering at a historic house or estate in the area (Adwell House is about 2.4 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens, like those at hospitals such as Thame Community Hospital (about 2.7 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Part by part
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. They collect grease as the air cools and slows, and we clean them section by section through access panels.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Common questions in Sydenham
Do you work at weekends in Sydenham?
Yes, we can come after you close and finish before you open. That way a site in Sydenham doesn’t have to lose a day’s trading. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Which fire and rescue service is responsible for Sydenham?
It’s Oxfordshire Fire and Rescue Service, which covers Sydenham. 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.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
How much does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, typically ready within one working day.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can extra access doors be added to the duct?
Yes, as part of our fits and repairs work. Panels go where they give the best access to sections that couldn’t be reached, and we will recommend where.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
What paperwork do you give after a duct clean?
Every clean comes with a photo report, plus a TR19 certificate when the whole system is cleaned. File them with the fire risk assessment.
