A survey and a fixed quote come first, then the visit at a time that suits you. For Tewin Wood, the closest hospital is Queen Elizabeth II Hospital, roughly 3.5 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

About our ventilation duct cleaning in Tewin Wood
Beyond the kitchen, TR19® Air covers the ordinary supply and extract systems that serve offices, schools and other buildings. It’s risk-based and inspection-led, so we look before we clean. The work covers general extract ductwork, hospitals and care homes and offices and schools, and the jobs we see most are musty smells from the ventilation and dust marks around grilles and ceiling diffusers.
Work in a small place like Tewin Wood starts with agreeing access and timings.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Log every filter change
- Keep to the inspection interval in your report
- Do not run the ventilation while builders are sanding or cutting
- File each ventilation report with the building records
Before any works, think about the ducts. Turn off the system or cover the openings during dusty jobs.
Protect the system during building work by switching it off or covering the grilles.
Why act early in Tewin Wood
An inspection-led approach avoids cleaning ducts that do not need it. Skipping it leaves you guessing. Rural sites cannot always move to another kitchen or room when something fails.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or send us an email, and we will talk you through it.

What the work involves, part by part
Hospitals and care homes
People in hospitals and care homes can be more vulnerable to poor air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.
Supply ductwork
Dust in supply ducts can be blown straight into occupied rooms. We clean the runs so it is not blown back in.

The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a weekend for a modest system, with large buildings phased floor by floor. We agree a date with you, plan the drive to Tewin Wood and turn up when the site is quiet.
- First we check the layout and any past paperwork.
- We inspect the ducts at chosen points to see where cleaning is needed.
- We cover the area below and turn off the system.
- We clean the system and remove the debris from site.
- We report on the work, listing any inaccessible sections and the next inspection date.
Getting ready for the visit
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards

Common questions in Tewin Wood
Can a school’s ventilation in Tewin Wood be done out of term time?
Yes. The holidays are the usual time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Tewin Wood. Send us your term dates when you call 0345 646 2711 or send us an email, and we will fit the work in.
Can you get to a site in Tewin Wood?
Yes. Villages and rural sites across the South East are part of our work, Tewin Wood included. A survey first, from pictures or a visit, means we arrive with the right kit.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Who has the legal duty for fire safety?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
How long does ventilation cleaning take?
Expect it to take a weekend for a modest system, with large buildings phased floor by floor. The size of the system and the access make the biggest difference.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you survey the system first?
Yes. TR19® Air is inspection-led, so we look inside the ducts at set points and record what we find. We recommend cleaning where the inspection shows it’s due.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. 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. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
