Canopy cleaning in Wallington
Dripping edges and a sticky hood are the first things a visitor notices. What is not seen, behind the filters, tends to be worse. We clean both, so the canopy is clean where it shows and where it does not. Common call-outs are for fat running down the front of the hood and an EHO comment about the canopy, on island canopies, plenum chambers and baffle filters.
Work in a small place like Wallington starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
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 are fully insured.

The process
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. If the van will struggle with a lane or gateway near Wallington, let us know and we’ll plan around it.
- We look at the canopy first, from photos or on a visit.
- The range is turned off and allowed to cool before we cover it.
- Filters come out and the plenum behind them is scraped and degreased.
- The canopy is cleaned inside and out, including troughs and seams.
- Clean filters are refitted and before and after pictures go into your report.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Make sure equipment near the work can be switched off and left to cool

What else we do in Wallington
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What happens if it’s left?
A blocked plenum and clogged filters cut the airflow at the canopy. The kitchen gets hotter and smokier, and the fan works harder for less. Cleaning restores the path the air should take. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

- Survey first, then a fixed quote
- One number for every site across the South East and London

Your questions about canopy cleaning in Wallington
Is Wallington within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Which fire authority looks after Wallington?
That’s Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
Do you clean inside the canopy as well as outside?
All of it: the outer surfaces, the inner skin, the seams and the troughs. We also remove the filters and clean the plenum and housing behind them, since that is where grease hides.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Are you fully insured?
Yes. We’re fully insured, and the details are available on request.
Who is the responsible person?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Kitchen extracts in Wallington
At about 34 miles from central London, Wallington sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Wallington is covered by Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Where a hall near Church of St Mary, or anywhere in Wallington, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Healthcare kitchens, like those at hospitals such as Fairfield Hospital (about 5.6 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Wallington is about 5 miles east of Letchworth, in Hertfordshire. We provide canopy cleaning for commercial premises of every kind in Wallington and the rest of Hertfordshire.

Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Grease filters too damaged to refit (they need replacing)
- A canopy undersized for the equipment
- A dirty extract fan further along the system

What the work covers
- Wall canopies
- Island canopies
- Baffle filters
- Canopy light fittings
- Plenum chambers
- Grease gutters
Do you need canopy cleaning in Wallington?
Air straight off the range hits the canopy first. Grease from the vapour lands on the canopy’s inner surfaces, its joints and its filters before what gets through reaches the plenum.
Most sites get in touch after spotting something like this:
- Heavy deposits behind the grease filters
- Condensation running down the canopy
- Greasy streaks across the canopy
- Fat running down the front of the hood
If you run catering at a historic house or estate in the area (Hinxworth Place is about 4.9 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning.

What the work involves, part by part
School and staff canteen kitchens
School and canteen kitchens often cook to set hours, so the canopy can be cleaned when the kitchen is closed. Holidays and weekends work well.
Grease troughs and gutters
A blocked or full trough is the usual cause of grease dripping from the canopy. We clean it out so the grease has somewhere to go.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep every filter in place while cooking
- Wash or exchange the filters on a regular cycle
- Use non-abrasive cloths on the hood
- Keep grease cups and drawers emptied
The kitchen is handed back clean, with the sheeting gone and the waste removed. Every filter is refitted and checked, and the kitchen is ready to cook.
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.
