Ventilation duct cleaning for kitchens and businesses in St Margarets
Dust in ventilation ductwork is not only a cleanliness issue. It slows the air, strains the fans and can be blown back out of the grilles. A clean puts the system back as it should be. If you’re dealing with rooms that feel airless when the system runs and ventilation full of debris from building work, we can put it right, from supply ductwork, general extract ductwork and offices and schools onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
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, trading since 2009.

Different parts, different methods
Schools and colleges
The work is fitted around term dates and events, with access agreed with the caretaker or site manager.
Grilles and diffusers
Dark streaks round a ceiling diffuser can be a sign of dirty supply air. The grilles are cleaned and the ducts behind inspected.
The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes a day or less for a small system and a series of visits for a large one. For a village or hamlet like St Margarets, tell us about narrow lanes, gates and parking when you book.
- We survey the system from drawings, photos or a site visit.
- Inspection comes next, with pictures of the inside of the ducts.
- Floors and furniture are covered and the ventilation turned off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions

In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
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.
What affects the cost of ventilation duct cleaning
Your quote is based on your site. We take into account:
- How big the system is
- One-off work versus a regular cycle
- Any permits to work or inductions
- The number of sites or systems
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
What we need to know
When you call or email, it’s useful to have:
- Problems your staff have spotted
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, ring 0345 646 2711, or email photos.
