How we handle ventilation duct cleaning in Great Wymondley
We cover Great Wymondley and the rest of Hertfordshire for ventilation duct cleaning, in offices, schools, healthcare buildings and retail. Each building gets a survey first and a fixed quote. If you are dealing with construction dust left in ducts after a refit and grilles and diffusers streaked with dirt, we can put it right, from offices and schools, hospitals and care homes and general extract ductwork onwards.
Somewhere as small as Great Wymondley, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
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.
When it’s something else
Some problems need a different service or another trade:
- Kitchen extract ductwork, which needs a TR19® Grease clean
- Damp or mould problems coming from the building fabric
- Design problems with the ductwork layout
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly.

Other services in Great Wymondley
Do you need ventilation duct cleaning in Great Wymondley?
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.
Clients usually contact us when they notice something like this:
- Systems with no record of inspection or cleaning
- Ducts that need a clean before handover
- Grilles and diffusers streaked with dirt
- Supply ducts with years of dust inside
Healthcare ventilation, from large hospitals like Lister Hospital (about 1.6 miles south-east) to small clinics, depends on clean filters, coils and ducts.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Report dust blowing from grilles right away
- Report leaks or damp near ceilings and risers
- Make sure nothing is stacked against extract grilles
- Book the next inspection on the date the report recommends
Keep up with filter changes to protect the ducts. Overdue filters are the quickest way to undo a duct clean.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
Different parts, different methods
Hospitals and care homes
In healthcare and care settings, there’s no quiet time. We plan the order of work with the site team so care carries on.
Grilles and diffusers
Grilles and diffusers that are designed to come out are removed for cleaning, then put back.
How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. If the van will struggle with a lane or gateway near Great Wymondley, let us know and we will plan around it.
- First the system is surveyed, on site or from pictures and drawings.
- Inspection comes next, with photos of the inside of the ducts.
- We protect the rooms beneath and switch the system off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Move anything stored near the system
