Grease filter exchange in Hornchurch
Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. Typical jobs include a canopy running with filters missing and smoke and heat lingering under the hood, across island canopies, restaurants and pubs and school and hospital kitchens.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Hornchurch, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
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 carry full insurance.

Fixed quotes for grease filter exchange in Hornchurch
You’ll get a fixed price before we start. It’s based on:
- The times the site is available
- One-off work versus a regular cycle
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
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 there are no surprises.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
What your team can do, and what needs us
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. That’s our job.
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.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Hornchurch and across Greater London. Larger estates can be phased building by building around the people who use them.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Different parts, different methods
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters though typically at a gentler pace.
The plenum
Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.
Grease filter exchange around Hornchurch
Food Standards Agency records include about 26 pubs and bars within about 1.5 miles of central Hornchurch. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Hornchurch 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.

When to call us in Hornchurch
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters, and day by day they load up and airflow falls away.
These are the problems we see most often:
- Filters so greasy the air can barely pass
- A canopy that drips grease
- Weak extraction at the canopy
- A greasy plenum behind the filters
A kitchen near Emerson Park station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What your quote should include
- When they can work, and whether that is outside your opening hours
- Which accreditations they hold, and whether you can check them
- Whether inaccessible sections are listed on the report
- Whether the quote shows VAT
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes less than an hour in most kitchens. In a London area like Hornchurch, parking, loading and building access are planned before the day of the work.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.

Hornchurch: your questions answered
Can a school canteen extract in Hornchurch be done out of term time?
Yes, holiday work suits schools best. There are about 33 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hornchurch. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we will fit the work in.
Which fire service covers Hornchurch?
Fire safety enforcement in Hornchurch is handled by London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How often should grease filters be changed?
The right interval depends on the kitchen. If filters clog early, the interval needs shortening, and we can change it.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Does a filter exchange disrupt service?
A change takes well under an hour for most canopies, so disruption is small. We plan visits outside your busiest times wherever possible.
Can you give a price for filter changes?
We price it on the number of filters and the visit frequency. Tell us what you have and we’ll come back with a fixed quote, typically within one working day.
