Ventilation duct cleaning for kitchens and businesses in Shenleybury
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. The work covers hospitals and care homes, supply ductwork and toilet extract systems, and the jobs we see most are ductwork with too few access panels to clean and extract ducts clogged with lint and dust.
Somewhere as small as Shenleybury, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Shenleybury
If a building in Shenleybury has just been refitted, now is the time to clean the ductwork. Otherwise construction dust left in the ducts is blown out once the system runs. Our emergency line runs 24/7, but a planned visit to Shenleybury is calmer for everyone.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
Why book with us
- Full insurance on every job
- Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
- Accredited under CHAS and SafeContractor, with ISO 9001
- Work around your opening hours, with 24/7 emergency cover
For landlords and multi-site operators
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Keeping the system healthy
To keep the system working properly between visits:
- Report dust blowing from grilles straight away
- Make sure nothing is stacked against extract grilles
- Wipe grilles and diffusers during routine cleaning
- Keep the TR19 certificate and photo report in the maintenance log
The report includes a recommended date for the next inspection, based on what we found. Put it in the diary now so it is not missed.
Fix leaks and damp near the ductwork quickly, as moisture makes dust stick.
Your questions about ventilation duct cleaning in Shenleybury
Can ventilation in schools around Shenleybury be cleaned out of term?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of Shenleybury. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you work in Shenleybury outside opening hours?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Shenleybury needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you cover Shenleybury?
Yes. Our area takes in London and the counties of South East England, Shenleybury included.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
How does TR19 Air differ from TR19 Grease?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. Under TR19® Air, inspection decides when cleaning is needed.
How often do ventilation ducts need cleaning?
Inspection should decide it, in line with TR19® Air. Busy or sensitive buildings may need it more often.
When to call us in Shenleybury
It matters for the people inside: dusty ducts can blow debris back into rooms, restrict airflow and make fans work harder. Where people are vulnerable, as in healthcare and care settings, the stakes are higher.
These are the problems we see most often:
- Systems missing access panels
- Supply ducts with years of dust inside
- Grilles and diffusers streaked with dirt
- Stuffy rooms and stale air
If you run a surgery, dental practice or care home near Shenleybury, clean ventilation matters as much to you as to a hospital like Kingsley Green (about 0.7 miles west).

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
