The process
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes a day or less for a small system and a series of visits for a large one. A quick note on how to find the site and where to park makes a visit to Over Wallop run smoothly.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- Before pictures are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after pictures and send the certificate and report.
Before we arrive
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
Ask for 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 so you know the cost before work begins.

Ventilation duct cleaning in Over Wallop, done properly
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. Common call-outs are for duct runs that can’t be reached for cleaning and construction dust left in ducts after a refit, across hospitals and care homes, toilet extract systems and general extract ductwork.
In a village or hamlet like Over Wallop, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Why deal with it now?
Dust streaks around grilles and stale rooms suggest the ducts need looking at. Dealing with them now stops them getting worse. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

How we price ventilation duct cleaning
The diagnosis comes before the price. We look at:
- The times the site is available
- The condition we find in the survey
- How many systems or sites are involved
- Whether we need access equipment or extra panels
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
To speed up the quote, send us:
- The postcode and the type of business
- Wide pictures of the system and the area around it
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Part by part
Offices and retail
Fit-outs in offices and shops leave dust in the ventilation. Cleaning before the new occupants move in makes sense.
Schools and colleges
Busy classrooms send a lot of dust and fibre into extract ducts. Inspection shows when cleaning is due.
Signs you need ventilation duct cleaning in Over Wallop
Refits and building work send dust into ventilation systems, especially when the system runs during the work. That dust can stay in the ducts long after the builders leave.
Signs it’s time to call us include:
- Systems missing access panels
- Grilles and diffusers streaked with dirt
- Stuffy rooms and stale air
- Damp or stale smells from grilles
In Over Wallop, we look inside the system before deciding what needs cleaning.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work aren’t the same thing. 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.
FAQs for Over Wallop
Do you work at weekends in Over Wallop?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you cover Over Wallop for ventilation duct cleaning?
Yes, Over Wallop is within the area we cover across London and the South East. Get in touch with the details and we will arrange a survey.
Will you look at the ducts before quoting?
Yes. Every job is surveyed first, from pictures, drawings or a site visit, and then quote a fixed price.
Will we have to shut during the visit?
Not normally. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages so parts stay in use.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Who is the responsible person?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What happens if parts of the ductwork can’t be reached?
Nothing is hidden: any section we couldn’t get into is listed. Access panels can be added where needed.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
