Grease filter exchange in Sydenham, done properly
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. The work covers wall canopies, baffle filters and school and hospital kitchens, and common reasons people get in touch are grease left in baffles after washing and weak extraction at the canopy.
London kitchens tend to trade late and open early, so extract cleaning in Sydenham is usually done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Grease filter exchange in Sydenham: the local picture
The FSA’s data shows about 54 bars, pubs and nightclubs and about 5 hotels and B&Bs registered in Sydenham and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected. Sydenham sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as Kirkdale School or anywhere near Sydenham, the holidays are the usual time for a TR19® clean. If you cook for passing trade around Sydenham station, the extract can be cleaned between your last and first customer. A hospital like St Christopher's Hospice, about less than half a mile south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Aftercare tips
After the visit, a few habits help the work last:
- Book full TR19 cleans alongside filter changes
- Make sure we can reach the canopy on exchange day
- Report a dripping canopy early
- Do not refit a filter that’s bent
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us to be cleaned.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
When it’s something else
It’s worth knowing the limits before booking:
- Greasy ducts and risers that a filter change will not reach
- A canopy that doesn’t capture the vapour properly
- A noisy or failed extract fan
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly.

FAQs for Sydenham
Can a school canteen extract in Sydenham be done out of term time?
Yes, holiday work suits schools best. With about 40 schools and colleges on the FSA’s register within roughly a mile and a half of Sydenham, it pays to plan holiday dates ahead. Just call us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
What do you need to know about parking in Sydenham?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Where do the greasy filters go?
They leave with us. That’s how an exchange works: you always have a clean set fitted and nothing greasy left on site.
Does a filter exchange replace TR19 cleaning?
No. The rest of the system still collects grease at the right interval.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Will I get paperwork for my records?
Yes. Each visit ends with a written report and photos, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. A fixed quote follows.

How we price grease filter exchange
The diagnosis comes before the price. We look at:
- Site rules, permits and inductions
- The times the site is available
- How easy every part is to reach
- Travel, parking and unloading
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
Helping us quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Your last certificate, test record or report
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Different parts, different methods
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
Leave it or put it right?
Clogged filters choke the extract. Heat and fumes hang in the kitchen while the fan strains. A regular exchange keeps the airflow where it should be. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
