Ventilation duct cleaning for businesses, landlords and public buildings in Knaphill. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

- Damp or stale smells from grilles
- Ducts that need a clean before handover
What the work involves, part by part
Grilles and diffusers
Dust marks around grilles can point to dirt further back in the system. We clean the grilles and look at what’s behind them.
Supply ductwork
Supply runs are inspected at set points first before deciding what to clean.
Ventilation duct cleaning in Knaphill, done properly
Inspection comes first. The ducts are opened at access points and the condition recorded, then recommend cleaning where it’s needed. That keeps the work in proportion to the risk. We’re often asked to deal with grilles and diffusers streaked with dirt and stuffy rooms and stale air, across offices and schools, hospitals and care homes and grilles and diffusers.
Smaller buildings around Knaphill often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Also in Knaphill
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, and that is where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Knaphill questions
Can ventilation in schools around Knaphill be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Knaphill, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Can you come to Knaphill after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
How do you deal with ducts you cannot get into?
We clean what we can reach and note the rest. Extra access panels can solve it, and we can quote for them.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
What information do you need?
A short description and a few pictures plus the address and your hours. If we need more, we will ask.

There are about 4 schools, colleges and universities and about 10 hospitals, care homes and childcare premises on the FSA’s food hygiene register across Knaphill and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Brookwood Hospital is the nearest hospital, about within half a mile south of Knaphill.

Visits are booked around your hours, evenings and weekends included.

What we are called out for in Knaphill
Moisture in ducts makes dust stick. Where there’s condensation or a leak, dust clings and builds faster, which is harder to shift later.
Look out for these warning signs:
- Ventilation that needs a TR19® Air inspection
- Systems missing access panels
- Rooms that feel airless when the system runs
- Toilet and washroom extracts full of fluff
If you manage a school such as Knaphill School, ventilation cleaning is best booked for the holidays.
Before booking anyone
- Which accreditations they hold, and whether you can check them

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
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. Where responsibility is shared, records matter even more.
What affects the cost of ventilation duct cleaning
Every site gets its own quote. This is what makes a difference:
- One-off work versus a regular cycle
- The times the site is available
- What state the system is in
- Site requirements such as sign-in and permits
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

How it works
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 before we start, and the area around the work is covered and protected. On site, it takes anything from a single shift for a small office to a planned programme of nights for a large building. Tell us when your site near Knaphill is quiet and the visit will be booked for then.
- First the system is surveyed, on site or from pictures and drawings.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- Debris is cleared from the duct runs, then grilles and diffusers are cleaned.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
