Signs you need grease filter exchange in Belmont
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.
These are the problems we see most often:
- Grease left in baffles after washing
- Grease filters clogged with grease
- Drips falling from the filters onto equipment
- Bent or damaged filters that don’t sit properly
A hall kitchen that only cooks for events, whether near Church of St Anselm or elsewhere in Belmont, still needs its extract cleaned, just less often.

Grease filter exchange in Belmont, done properly
A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. If you are dealing with gaps where filters have been removed and smoke and heat lingering under the hood, we can put it right, from mesh filters, wall canopies and restaurants and pubs onwards.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Belmont, that normally means a longer system to clean and more access panels to plan around.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What else we do in Belmont
Why act early in Belmont
Leaving filters too long pushes more grease into the plenum and ducts. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. Leaving it on a busy London site only adds to the work.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
What a clean won’t put right
We’d rather tell you now than book work that will not help, so here are the limits:
- A canopy that does not capture the vapour properly
- Cooking smells reaching neighbours, which need odour control
- A fan that’s failing or too weak for the system
If in doubt, call 0345 646 2711, or email photos and we’ll say what we think before you book.

Common questions in Belmont
Which fire authority looks after Belmont?
Fire safety enforcement in Belmont is handled by London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can the work in Belmont be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What’s the right interval for changing filters?
It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than lighter ones. We agree the interval with you.
What we do, step by step
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. A name and number for whoever controls access to the building in Belmont saves time on the night.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- 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.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

There are about 154 restaurants, cafés and works canteens and about 59 takeaways within 1.5 miles or so of the middle of Belmont, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. London Fire Brigade covers Belmont. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. London jobs normally start after the last service, with loading and roof access agreed with the building first.

How the job changes from site to site
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Regular changes help protect the ductwork.
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
