Great Hormead: your questions answered
Do you work at weekends in Great Hormead?
Yes. We work evenings, overnight and at weekends. That way a site in Great Hormead doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you get to a site in Great Hormead?
Yes, we work in villages as well as towns, and Great Hormead is covered. The journey is planned ahead, so a few details about the route help.
Can you quote from pictures?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
How do you deal with ducts you can’t get into?
We clean what we can reach and note the rest. Fitting access panels tends to be the answer, and we can quote for them.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.

Signs you need ventilation duct cleaning in Great Hormead
Refits and building work send dust into ventilation systems, especially when the system runs during the work. Plaster, wood and masonry dust can sit in the ducts for years.
Common reasons sites call us are:
- Dusty supply ductwork that hasn’t been cleaned in years
- Blocked general extract ductwork
- Systems missing access panels
- Dust marks around grilles and ceiling diffusers
If you manage a school such as Hormead Church of England (VA) First School, ventilation cleaning is best booked for the holidays.

What ventilation duct cleaning cannot fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Leaks from roofs, pipes or walls into the ductwork
- Problems with how the system is controlled
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
If you are not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.
Where we work
- Grilles and diffusers
- Hospitals and care homes
- Toilet extract systems
- Offices and schools
- General extract ductwork
- Supply ductwork
Different parts, different methods
Extract ductwork
A dirty extract duct makes its fan work harder. Clearing the duct helps the fan do its job.
Grilles and diffusers
Dark streaks round a ceiling diffuser can be a sign of dirty supply air. We clean the grilles and look at what’s behind them.
How we price ventilation duct cleaning
Your quote is based on your site. We consider:
- Site requirements such as sign-in and permits
- How many systems or sites are involved
- What state the system is in
- Access, including roofs, risers and ceiling voids
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What happens if it’s left?
After building work, cleaning the ventilation before people move back in makes sense. Otherwise the dust from the works comes out of the grilles once it’s switched back on. In a place like Great Hormead, ductwork and fans are easy to forget until something goes wrong.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Report leaks or damp near ceilings and risers
- Wipe grilles and diffusers during routine cleaning
- Flag any dust coming out of the vents
- Keep filters changed on time
Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.
Keep filters changed on time. Overloaded or poorly seated filters let dust straight through.
