What affects the cost of canopy cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- One-off work versus a regular cycle
- The condition of the system
- How many systems or sites are involved
- Site requirements such as sign-in and permits
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or email us, and we’ll talk you through it.

How we handle canopy cleaning in Garston
The canopy is where the extract system breathes in. If it’s coated in grease, everything downstream gets more of it. Our diagnosis starts there, and the cure is a thorough clean of the hood, the plenum and the filter housing. If you have fat running down the front of the hood and a hood coated in old grease, we can help.
For a smaller kitchen near Garston, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Managing agents and facilities teams in Garston
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a few hours, depending on the size of the canopy and how much grease has built up. Everything the job in Garston needs is worked out beforehand, from the survey.
- The canopy is checked from photos or on a visit.
- Out of hours, the range is switched off, cooled and covered.
- We lift out the filters and scrape the plenum and housing.
- Inside and out, the hood and its troughs are cleaned.
- Filters are refitted, the area cleaned down and the photo report put together.
How to prepare
- Clear the space around the work
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before we start.

Garston: your questions answered
Can you clean school kitchen extracts in Garston during the holidays?
Yes, and it’s the easiest time to do it. With about 20 schools and colleges on the FSA’s register within roughly a mile and a half of Garston, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Which environmental health team covers Garston?
In Garston, it’s Watford council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
What kinds of canopies do you clean?
Most commercial kitchen canopies, from one small hood to a long run of canopies. The survey tells us how best to clean yours, from photos or a visit.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
What happens to the filters during the clean?
We remove the filters to reach the plenum, and they’re cleaned before going back in. Any that are damaged are noted on the report.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How much does canopy cleaning cost in Garston?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll usually reply within one working day.
How the job changes from site to site
Plenums and filter housings
Filter housings hold the filters in place, and their channels fill with grease. Clean housings let the filters seat properly and leave no gaps.
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.
Signs you need canopy cleaning in Garston
Because the plenum sits behind the filters, it’s easy to forget. Kitchen staff clean what they can see, so the plenum often carries months of grease.
Signs it’s time to call us include:
- Fat running down the front of the hood
- A filter housing caked in grease
- Wet, greasy drips from the hood
- Greasy streaks across the canopy
Bursars and site managers at schools such as The Grove Academy tend to book extract cleaning for when the kitchen is empty.

What else we do in Garston
Why act early in Garston
In Garston, as elsewhere, a greasy canopy is one of the first things an inspector sees. Keeping it clean shows the rest of the kitchen is being looked after and keeping it that way is easier than catching up. You choose the date of a planned visit, and a breakdown never asks.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What you get with us
- Survey first, then a fixed quote
- CHAS and SafeContractor accredited, with ISO 9001
- Each visit written up, with photos
- Evenings, overnight and weekends, plus 24/7 emergency callout
Grease, kitchens and Garston
Food Standards Agency data counts about 50 restaurants, cafés and works canteens and about 18 takeaways in and around Garston, up to about a mile and a half out. Any of those kitchens with a canopy has a hood that needs cleaning inside and out. Garston is covered by Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Watford council inspect food businesses in Garston. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Commuter trade near Garston station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. If you run a church or community hall kitchen, near Stanborough Park Church or elsewhere in Garston, its extract still collects grease from every lunch and event.
