About our ventilation duct cleaning in Grovehill
We get into the ducts through access panels at intervals along the system. Where there aren’t enough panels to reach every section, we note the uncleaned parts in the report, and we can fit new panels for the next clean. We are often asked to deal with construction dust left in ducts after a refit and supply ducts with years of dust inside, across grilles and diffusers, general extract ductwork and hospitals and care homes.
In a place like Grovehill, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Questions from Grovehill
Can ventilation in schools around Grovehill be cleaned out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 35 schools, colleges and universities with registered kitchens within about a mile and a half of Grovehill. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Do you cover smaller places like Grovehill?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How often should ventilation ductwork be cleaned?
That varies with the building, the filters and how hard the system works. Inspecting regularly shows when cleaning is needed.
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.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Will we have to shut during the visit?
Not normally. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits so parts stay in use.
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to 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.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Don’t block grilles with furniture or storage
- Diary the next TR19® Air inspection
- Do not run the ventilation while builders are sanding or cutting
- Log every filter change
Share the report with whoever looks after the building’s maintenance, so the history stays together. Year on year, it shows how fast dust builds up.
Good filter maintenance protects the ductwork. Overdue or badly fitted filters let dust into the supply ducts.
Signs you need ventilation duct cleaning in Grovehill
Most ductwork is out of sight, so dust collects unseen. The grilles get a wipe, but what’s behind them does not.
Clients normally contact us when they notice something like this:
- Construction dust left in ducts after a refit
- Musty smells from the ventilation
- Systems with no record of inspection or cleaning
- Poor airflow from the vents
Healthcare buildings such as Hemel Hempstead Hospital, about under half a mile south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Grovehill, yours matters too.

Different parts, different methods
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.
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.
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a weekend for a modest system, with large buildings phased floor by floor. Your opening hours decide when we come to Grovehill, not ours.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After photos are taken and the certificate and report issued.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
