Nash Mills canopy cleaning
We cover Nash Mills for canopy cleaning. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Grease channels that no longer drain
- Grease filters blocking between washes
- Greasy streaks across the canopy
Why deal with it now?
For a kitchen in Nash Mills, a canopy that looks greasy can colour a whole inspection. A clean hood is a sign the kitchen is cared for and keeping it that way is easier than catching up. A site near Nash Mills that has to close at short notice is hard to cover for.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Why choose Duct Doctor in Nash Mills
- We diagnose before we treat
- Fixed quotes, normally within one working day

About our canopy cleaning in Nash Mills
Grease troughs, seams and the inside edge of the canopy are the spots a daily wipe misses. Thick deposits are scraped off by hand, then the surfaces degreased to suit what’s there, using hot water or steam where it helps. If you have a plenum thick with grease behind the filters and wet, greasy drips from the hood, we can put it right.
For a smaller kitchen near Nash Mills, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Grease, kitchens and Nash Mills
The FSA’s data shows about 16 pubs and bars registered in and around Nash Mills, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Nash Mills, food businesses are inspected by environmental health officers from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Nash Mills sits within the area of 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.
If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 1.7 miles north-west, the extract may need cleaning more often than a part-time kitchen. A hall kitchen that only cooks for events, whether near Church of St Mary or elsewhere in Nash Mills, still needs its extract cleaned, just less often.
Nash Mills is about 2 miles south of Hemel Hempstead, in Hertfordshire. We provide canopy cleaning for commercial premises of every kind in Nash Mills and the rest of Hertfordshire. Nash Mills is one of 381 places in Hertfordshire where we work for commercial clients. We also work in London, about 22 miles from Nash Mills.

Questions from Nash Mills
Can you clean school kitchen extracts in Nash Mills during the holidays?
Yes, holiday work suits schools best. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Nash Mills. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who is the fire and rescue service for Nash Mills?
It’s Hertfordshire Fire and Rescue Service, which covers Nash Mills. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you clean inside the canopy as well as outside?
Inside and out, along with its seams and grease channels. The plenum and filter housing behind the filters are cleaned too.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
Do you provide photos of the cleaned canopy?
Every clean comes with a photo report that lists what was cleaned and anything we couldn’t reach. Where the whole system is cleaned, you also get a TR19 certificate through the BESCA Vent Hygiene Elite portal.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
Why is my canopy dripping grease?
Typically because the troughs or gutters are full, or the plenum is overloaded. With nowhere to collect, the grease overflows, and condensation can carry it too. Cleaning the canopy and plenum clears it.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
How we price canopy cleaning
We quote each job individually. These are the things that affect it:
- Site requirements such as sign-in and permits
- The condition we find in the survey
- Parking and loading at the site
- The size of the system
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we’ll explain what it covers.
What to send for a quote
You don’t need the technical terms. Just send:
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks

What the work involves, part by part
Pub and hotel kitchens
A hotel or pub kitchen can rarely close for long. We clean the canopy overnight or between services so the kitchen keeps trading.
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.
What we’re called out for in Nash Mills
Steam and condensation make canopy grease harder to deal with. Water vapour condenses on the cooler canopy surfaces and drips, carrying grease with it. The result is sticky streaks and drips onto the range.
Common reasons sites call us include:
- A hood coated in old grease
- Grease filters blocking between washes
- Condensation and grease dripping together
- A filter housing caked in grease
If you run a café or takeaway near Apsley station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- Proof of insurance
- Whether a written report and pictures are included
- How they set the interval to the next visit
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
How it works
Each visit runs to the same pattern: protect the area, make the system safe, carry out the canopy cleaning, tidy up and leave you the report. On site, the work takes part of a shift for most kitchens, more where there are several canopies or heavy deposits. For a place like Nash Mills, we load the van from the survey notes so the work can be done in one visit where possible.
- We start by checking the canopy and what’s behind its filters.
- We protect everything below once it has cooled.
- Heavy deposits come off by hand, then the surfaces are degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- The canopy is signed off with before and after pictures and a next clean date.
Preparing for the visit
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Let us know about permits to work or site inductions
Ask for a quote
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.
Advice
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
