Common questions in Mapesbury
What do you need to know about parking in Mapesbury?
A loading bay, a visitor permit or off-street space near the site in Mapesbury makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.
Can a school canteen extract in Mapesbury be done out of term time?
Yes. The holidays are the usual time for school work. With about 33 schools and colleges on the FSA’s register within roughly a mile and a half of Mapesbury, it pays to plan holiday dates ahead. Just call us on 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you clean inside the canopy as well as outside?
The whole canopy, inside and out. We also remove the filters and clean the plenum and housing behind them because that is often the dirtiest part.
What about areas you can’t get to?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Are the filters cleaned too?
They’re taken out, cleaned and refitted. Each filter is checked for fit as it goes back, because gaps let grease through.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.
How we handle canopy cleaning in Mapesbury
Duct Doctor has cleaned canopies and hoods since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001. The work covers wall canopies, island canopies and grease gutters, and the jobs we see most are filters that clog soon after cleaning and grease dripping from the canopy edge.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Mapesbury, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

When to call us in Mapesbury
Any canopy in Mapesbury that’s used for cooking will gather grease in the end. That grease is fuel sitting right above the heat, so a flare-up near a greasy hood can quickly become a fire.
Common reasons sites call us include:
- Filters that clog soon after cleaning
- Grease dripping from the canopy edge
- Condensation and grease dripping together
- Canopy gutters full of old fat
For schools such as St Joseph's RC Infant School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
Before you book anyone
- What insurance they carry
- When they can work, and whether that is outside your opening hours
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Grease, kitchens and Mapesbury
According to Food Standards Agency records, there are about 21 bars, pubs and nightclubs and about 7 hotels and B&Bs within roughly a mile and a half of the centre of Mapesbury. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Mapesbury is covered by London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Most London extract cleaning happens at night, after the last service.
Healthcare kitchens, like those at hospitals such as Neasden Hospital (about 0.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you cook for passing trade around Wembley Stadium station, the extract can be cleaned between your last and first customer.

When it’s something else
We will always give you a straight diagnosis, so here’s what canopy cleaning will not do:
- Filters that no longer seal in the housing
- Grease in the duct runs and risers behind the canopy
- A hood that doesn’t cover the cooking line
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before booking.

In-house cleaning or a specialist?
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. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Different parts, different methods
Pub and hotel kitchens
In pubs and hotels, the kitchen may be busy for much of the day. Long hours mean the canopy collects grease fast, so it may need cleaning between full TR19 cleans.
Island canopies
Everything about an island canopy is on show, so the finish matters. It’s degreased and photographed for your report.

The process
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes a few hours for most canopies. Security desks and permits-to-work are routine in London, so let us know what your building in Mapesbury needs from us.
- First the canopy is surveyed, by pictures or in person.
- Equipment below is switched off and left to cool, then sheeted.
- Filters come out and the plenum behind them is scraped and degreased.
- We degrease the canopy shell, its seams and the grease troughs.
- We refit the filters, clear up and photograph the finished canopy.
Before we arrive
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site
Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
Advice
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Give the canopy a wipe after service
- Don’t scrape the canopy with metal tools
- Check and empty canopy gutters regularly
- Clean the baffle filters often
We clear away the sheeting, waste grease and water before we leave. Every filter is refitted and checked ready for the next service.
Tell us if the canopy starts dripping or the filters clog sooner than usual. It can mean the cooking has changed or the interval is too long, which a grease thickness test can confirm.
