Hertfordshire · Ventilation duct cleaning
Ventilation duct cleaning in Newnham, Hertfordshire
We cover Newnham for ventilation duct cleaning. Out-of-hours visits, a fixed quote and a written report with photos on every job.
- Damp or stale smells from grilles
- Ventilation that needs a TR19® Air inspection
- Ductwork with too few access panels to clean
Leave it or put it right?
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. A planned visit to Newnham is easier to arrange than an emergency callout.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

Ventilation duct cleaning in Newnham, done properly
A dusty duct in a building in Newnham is more than an eyesore. 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. The work covers hospitals and care homes, supply ductwork and general extract ductwork, and the jobs we see most are dirty diffusers dropping dust into rooms and ductwork that hasn’t been inspected.
In a village or hamlet like Newnham, 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. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

How it works
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from one overnight visit to a phased programme over several weeks. The timing of a visit to Newnham is set by you, and the travel is our side of the planning.
- 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.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
Preparing for the visit
- Have your last certificate or report to hand
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Signs you need ventilation duct cleaning in Newnham
Ventilation hygiene often gets left out of planned maintenance. Plant can be well serviced while the ductwork goes untouched for years.
If you notice any of these, it’s worth a diagnosis:
- Ducts that need a clean before handover
- Grilles and diffusers streaked with dirt
- Ductwork that hasn’t been inspected
- Musty smells from the ventilation
For schools like The Knights Templar School, the holidays are the usual time to inspect and clean ventilation.

Newnham questions
Do you cover Newnham for ventilation duct cleaning?

What does TR19 Air cover?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. TR19® Air takes an inspection-led, risk-based approach.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you provide a report?
Yes, a TR19® certificate and pictures. It also notes unreached sections and a recommended next inspection.
How often do ventilation ducts need cleaning?
Under TR19® Air, the answer comes from inspecting the ducts. Heavily used buildings, or those with vulnerable occupants, may need attention more often.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you survey the system first?
Yes, always. We check the layout, access and condition before giving a fixed quote.

What affects the quote in Newnham
The quote reflects the site in front of us. We consider:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- A few general shots of the system
- Where the site is and what kind of site it is
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Get leaks near ductwork fixed quickly
- Book the next inspection on the date the report recommends
- Log every filter change
- Keep the TR19 certificate and photo report in the maintenance log
We recommend when the system should next be inspected, in line with the risk-based approach of TR19® Air. Put it in the diary now so it doesn’t slip.
Protect the system during building work by turning it off or covering the openings.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
