How we handle ventilation duct cleaning in High Leigh
We cover High Leigh and the rest of Hertfordshire for ventilation duct cleaning, from offices and schools to hospitals, care homes and shops. Each building gets a survey first and a fixed quote. The work covers general extract ductwork, offices and schools and toilet extract systems, and people most often call us about stuffy rooms and stale air and toilet and washroom extracts full of fluff.
Somewhere as small as High Leigh, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We have 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 are fully insured.

In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a shift or two for a small system, longer for a whole building. Photos of the system and how to reach it help us plan a visit to High Leigh.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- After pictures are taken and the certificate and report issued.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
- Arrange a key holder or contact on site
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Related advice
Between visits
Aftercare is simple, and it helps at the next visit:
- Report dust blowing from grilles right away
- Make sure nothing is stacked against extract grilles
- Keep the TR19 certificate and photo report in the maintenance log
- Report leaks or damp near ceilings and risers
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
Good filter maintenance protects the ductwork. Overloaded or poorly seated filters let dust straight through.
What we’re called out for in High Leigh
In a building in High Leigh, the ventilation may run for long hours every day, and every hour of running brings more dust with it. Heavier use means faster build-up.
Signs it’s time to call us include:
- Ductwork that hasn’t been inspected
- Toilet and washroom extracts full of fluff
- Damp or stale smells from grilles
- Rooms that feel airless when the system runs
For schools like Westfield Community Primary School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book

- Proof of insurance
- What happens if part of the system can’t be accessed
- What’s included in the scope, part by part
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

What affects the cost of ventilation duct cleaning
A fixed price needs a few facts first. We look at:
- The condition we find in the survey
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- The paperwork from the last visit, if you have it

What the work involves, part by part
Supply ductwork
Supply ducts carry air from the AHU into the rooms. Dust that slips past the filters builds up inside, and we remove it through access panels.
Schools and colleges
Holidays and weekends are the natural time to clean school ventilation, when classrooms are empty.

High Leigh: your questions answered
Will you come out to High Leigh?
Yes, we work in villages as well as towns, and High Leigh is covered. The journey is planned ahead, so a few details about the route help.
Can you work in High Leigh outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in High Leigh can fit around your hours. Your opening times are the first thing we ask for.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
How long does ventilation cleaning take?
The clean takes a weekend for a modest system, with large buildings phased floor by floor. We’ll know more after the survey, and you can phone us on 0345 646 2711 or use the quote form to arrange it.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
What if there aren’t enough access panels?
We clean what we can reach and note the rest. Fitting access panels tends to be the answer, and we can quote for them.
