Ventilation duct cleaning in Farnham, done properly
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. Cleaning restores the clear airway the system was designed with. Common call-outs are for construction dust left in ducts after a refit and ductwork never cleaned since it was installed, across supply ductwork, offices and schools and hospitals and care homes.
Buildings in towns like Farnham often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Ventilation in Farnham buildings

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Stick to the filter change schedule
- Book the next inspection on the date the report recommends
- Tell your facilities team about dirty diffusers
- Switch the ventilation off or cover grilles during dusty building work
If there’s building work planned, protect the ventilation. Turn off the system or cover the openings during dusty jobs.
TR19® Air works through regular inspection. Inspecting on a schedule catches build-up before it becomes a big clean.
What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a day or less for a small system and a series of visits for a large one. A closed day, an evening or an early start: whichever suits your site in Farnham, we’ll book around it.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before photos are taken and the ducts cleaned section by section.
- We clean the grilles and diffusers and put them back.
- After photos are taken and the certificate and report issued.
How to prepare
- Move anything stored near the system
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site

Advice
Leave it or put it right?
If a building in Farnham has just been refitted, now is the time to clean the ductwork. Otherwise construction dust left in the ducts is blown out once the system runs. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Farnham, having the work done and recorded first helps.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What you get with us
- A fixed price before any work starts
- One number for every site across the South East and London
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Full insurance on every job

Questions from Farnham
Can a school’s ventilation in Farnham be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 10 schools and colleges on the FSA’s register within roughly a mile and a half of Farnham, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711, or email photos, and we’ll fit the work in.
Do you offer ventilation duct cleaning in Farnham?
Yes. We work across London and the South East, and Farnham is part of that. Just phone us on 0345 646 2711, or email photos with a few details of the site.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Can you quote from pictures?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
Will you look at the ducts before quoting?
Yes. Every job is surveyed first, from photos, drawings or a site visit, and then quote a fixed price.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
When should our ventilation next be cleaned?
TR19® Air is risk-based, so cleaning follows inspection rather than a fixed calendar. Each report recommends when the system should next be inspected.
How long will the duct cleaning take?
As a guide, it takes anything from a single shift for a small office to a planned programme of nights for a large building. Large buildings can be phased, often out of hours, and we’ll confirm the plan when we quote.
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
