About our ventilation duct cleaning in Deacon's Hill
Extract ducts from toilets, changing rooms and general areas collect dust and lint. Supply ducts carry anything the filters miss. Both are cleaned, with the area protected and the mess contained. If you have duct runs that can’t be reached for cleaning and toilet and washroom extracts full of fluff, we can put it right, from grilles and diffusers, general extract ductwork and hospitals and care homes onwards.
Work in a small place like Deacon's Hill starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Common problems we fix in Deacon's Hill
Building work is one of the biggest sources of debris in ducts, especially when the system runs during the work. That dust can stay in the ducts long after the builders leave.
Clients usually contact us when they notice one of these:
- Systems missing access panels
- Construction dust left in ducts after a refit
- Extract ducts clogged with lint and dust
- Musty smells from the ventilation
For workplaces around Elstree & Borehamwood station with mechanical ventilation, cleaning can be done in the evening or at weekends.
What to look for in a quote

- What insurance they carry

- Whether the figure could change on the day
Honest limits
Before you book, it helps to know what’s not included:
- Condensation caused by the building rather than the ducts
- Grease in kitchen extract systems, cleaned to TR19® Grease instead
- Ventilation that’s undersized for the building
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we will tell you honestly.

Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

Questions from Deacon's Hill
Can ventilation in schools around Deacon's Hill be cleaned out of term?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Deacon's Hill. Tell us your holiday dates and we will book the visit for when the site is empty.
Will you come out to Deacon's Hill?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Will you look at the ducts before quoting?
Yes. TR19® Air is inspection-led, so we look inside the ducts at set points, with photos of the inside. We recommend cleaning where the inspection shows it’s due.
Can you clean without closing the building?
Yes. We work evenings, overnight and weekends, so the building can carry on as usual.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
